Available in PDF, EPUB and Kindle. Book excerpt: Linum (flax) is a genus of about 200 species in the flowering plant family Linaceae. The genus includes common flax, which is one of the best fibers to produce linen, the seeds to produce linseed oil and has health-related properties of flax in human and animal nutrition. This book describes the genetics and genomics of Linum including the development of extensive experimental resources (e.g. whole genome sequence, efficient transformation methods, insertional mutant collections, large germplasm collections, resequenced genomes) that have led much progress and its economic importance. The methods and use of Linum to address a wide range of applications (e.g. disease resistance, cell wall composition, abiotic stress tolerance, floral development, natural diversity) is also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have shown that certain flax varieties are especially prone to genomic destabilization by the external growing environment. The best characterized variety that responds to this environmental stress is the fiber flax variety Stormont cirus, which is subsequently referred to Pl. Bethune is an oil seed variety, which appears to be genomically stable irrespective of the growth environment. To elucidate the genetic control of this phenomenon, a cross was made between Pl and Bethune. The F1 generation from this cross (Bethune x Pl) was grown in a non-inducing environment and appeared to be stable under this environment. However, when the F1 generation was grown under an inducing environment, then genomic variation was observed which is consistent with the character of inducibility under the stress of the external growing environment being a dominant characteristic. When F2 individuals from these non-induced F1's were grown under inducing conditions then, using the amplification of LIS-1 as the marker for inducibility, some individuals showed inducibility and some were stable. Scoring many loci in these induced F2's showed that many were inherited in the expected Mendelian pattern, but some were inherited anomalously. In general, the data indicated that there was an overabundance of Bethune parental alleles, where the allele in Bethune was the same as that in induced progeny from Pl. The alleles were characterized by PCR so individual loci were scored independently. Subsequently, whole genome sequencing was done for a set of DNAs isolated from these F2's. A 2Mb region of Chromosome 14 was selected because it is a potential region which contains multiple sections that respond to the growth environment. The rDNA, which is a quantitative polymorphism associated with the induction of genomic changes, was also assessed to observe the data for a different chromosome. Several potential blocks and some SNPs have been determined as the border of responsive regions. The rDNA data shows a different extent of responsiveness in F2 individuals and indicates that the induction may be under the control of 2 genes.

This book was released on 2011 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flax (Linum usitatissimum L.) undergoes heritable genomic changes in response to nutrient stress, including changes in total DNA content, rDNA copy number variation, and the insertion of Linum Insertion Sequence 1 (LIS-1). LIS-1 represents a novel type of insertion sequence, as it appears to be assembled from sequences dispersed throughout the flax genome before its insertion into a defined target sequence. To begin to find genes and genomic regions controlling the stress response, a genetic map of the flax genome was created using crosses between responsive and unresponsive lines of flax. Simple sequence repeats (SSRs) were isolated from the flax genome and markers that were polymorphic between the flax lines were used to create a preliminary genetic map, which contained 37 markers in 17 linkage groups. The responsiveness of the F2 offspring of reciprocal crosses between Stormont Cirrus, a responsive line, and Bethune, an unresponsive line, was determined. The appearance of LIS-1 was assayed using PCR on DNAs isolated from F2s grown under nutrient stress conditions at two time points. Changes in large and small rDNA copy number were also measured using quantitative PCR (qPCR). The number of loci involved in responsiveness was determined for each measure of responsiveness at each time point. Changes in rDNA copy number was determined to be the first step in the stress response, with 1-2 dominant loci controlling changes in the copy number of genes for large and small rDNA. The early insertion of LIS-1 appears to require 3-4 dominant loci, while a later response is controlled by 2 independent, dominant loci. The early LIS-1 response is linked to marker 258, while the late LIS-1 response is linked to marker JA23 and to the loci for the rDNA response. Marker 157-158 was linked to the rDNA response in the 5S genes. These markers indicate genomic regions in which the genes that control responsiveness reside, which can be analyzed in greater detail to identify specific genes controlling the response to nutrient stress in flax.

Available in PDF, EPUB and Kindle. Book excerpt: Flax (Linum usitatissimum L.), one of the eight founder crops of agriculture, is a versatile plant that has been a source of fiber and oil for millennia. Flax production, however, is constrained by various factors, including moisture stress. Yet, variations in the level of tolerance to different moisture regimes exists among flax germlines, thereby providing opportunities for breeders. To understand the global scale eco-geographic adaptation and to further gain insight into the genetic architecture of drought-related traits leading towards marker-assisted breeding and/or genomic selection in flax, a genome-wide investigation using high density single nucleotide polymorphism (SNP) data was performed in two sets of flax genotypes: a core (n=407) and a mini-core (n=115) collection, both representing the major world flax growing regions. The core collection was used to demonstrate haplotype distribution and possible driving forces that have shaped the population structure of the crop. The mini-core was used to perform genotype-phenotype association for drought-related traits through genome-wide association studies (GWAS) based on phenotypic values generated in two experiments. In the first experiment, 16 early root and shoot traits were evaluated using a semi-hydroponic pouch system in a controlled environment, while in the second experiment 11 drought-related traits were evaluated under irrigated and non-irrigated conditions. For the latter, GWAS was performed using the adjusted values of six of the measured traits that significantly responded to the watering regime, as well as six calculated stress indices for each trait. The genetic structure analysis clustered the core collection into four major groups: Temperate, South Asian, Mediterranean and Abyssinian. The Temperate group comprised the majority of the core collection and was dominated by accessions from Eurasia, the Americas and Oceania. Despite their limited representation, the other three groups harbored a high concentration of endemic haplotypes that can be attributed to the long history of flax cultivation in these regions hypothesized to be the centers of diversification the crop. More in-depth samplings from these regions is thus expected to broaden the genetic diversity of the flax core collection substantially. Genetic variation within morphotypes is more pronounced than between the fiber and oil types, reflecting selection of genotypes for dually elite traits i.e. both for seed and fiber. The overall result suggests the contribution of use-directed human selection and eco-geographic variations along the latitudinal gradient as major forces in shaping the genetic structure of the crop. The two GWAS experiments, i.e., early root-shoot growth and field-drought-tolerance-related traits, yielded 228 and 144 quantitative trait nucleotides (QTNs), respectively, that were associated with at least one trait. Most loci, 100 kb up- and downstream of the associated QTN, harbored genes predicted to play roles in modulating the associated trait or traits. In the root-shoot GWAS, genes predicted to encode GRAS transcription factors, mitogen-activated protein kinases (MAPKs), and auxin related lateral organ boundary proteins were present at root trait QTN loci, while QTN loci associated with shoot traits mainly harbored genes involved in photo-morphogenesis and plant immunity. QTN loci of drought tolerant traits consistently harbored genes known to mediate responses to abiotic stress, including drought, heat and salt, suggesting the importance of these loci for stress tolerance to be considered as candidate QTL of the traits associated with.

Available in PDF, EPUB and Kindle. Book excerpt: Inherited genetic change can happen in flax (Linum usitatissimum) due to environmental stress. The change can result in different phenotypes in flax progeny. The genetic changes can be induced during one generation and can result in stable genotypes in the next generation. Also the genetic changes are precise and repeatable that homozygous individuals show the same genome reorganization at specific sites in their progeny. Therefore, the genetic re-arrangements are not the result of a random process but a preference for a particular DNA structure, which indicates that possible new genes or functional fragments are formed during this process. The genomes of different varieties of flax are compared to explain the detail of the rapid but intentional genomic changes and regions of variation identified by whole genome comparisons. Possible mechanisms and the potential causes of these rearrangements bring a new light to modern plant genome studies and molecular evolution research.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract Flax (linseed, Linum usitatissimum L) is cultivated either for its seeds or its stem (bast fiber). With the goal of contributing to development of novel flax germplasm, a forward genetics screen of EMS mutagenized flax (var. CDC Bethune) was conducted to identify seeds with abnormal pigmentation or mucilage. Seeds of 16,764 M4 families were examined visually, with and without staining by Toluidine Blue. A total of 86 putative seed color mutants were identified, with the most common phenotype being yellow seeds. There were 1,975 identified putative mucilage mutants, with a range of phenotypes, including Blue Seed, No Mucilage Released, and Abnormal Mucilage Released. A subset of the seed colors and mucilage phenotypes were tested for heritability. The seed colors were generally heritable, but the mucilage phenotypes appeared to show variable expressivity that is probably highly dependent on the environment. Histological analysis revealed how seed coat anatomy changes affected seed color, but did not explain the mucilage phenotypes tested. The lines have been provided to flax breeders other collaborators for further analysis and potential use in breeding programs. GASA (Gibberellic Acid Stimulated in Arabidopsis) genes encode a family of small proteins of unknown biochemical function, whose expression has been correlated with various processes in plants including hormone response, defense, and development. GASA genes have also been reported in our lab to be expressed in developing flax stems. To better characterize the GASA-like gene family in flax, I identified 20 predicted GASA-like genes in the flax whole genome assembly. Using microarray and qRT-PCR analysis, seven of these genes showed differential transcript expression during stem development. I cloned and verified the sequences of these genes. Based on these studies, I was able to define groups of flax GASA-like genes whose expression was well-correlated with stem segments in either the elongation or cell wall deposition stage. These results provide further evidence that specific GASA genes are involved in different processes in flax stem and/or fiber development.

This book was released on 2012 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent sequencing and assembly of the Bethune genome, a linseed type, and the sequencing of several of the genotrophs of Stormont cirrus, a fiber type, provided a platform for analysis of structural variation sites between flax fiber and linseed types which could be used to identify regions worthy of investigation for the improvement of seed and fiber traits in flax. The most well characterized site of structural variation in flax is that of LIS-1, an environmentally inducible and heritable 5.7Kb structural variation. Previous investigations suggest the LIS-1 structural variant is the result of a programmed DNA rearrangement. The only vaguely comparable system for controlled or programmed DNA rearrangement is that seen in the ciliate macronucleus. The scnRNA mechanism used by ciliates utilizes much of the same machinery as that of small RNAs and the action is similar to that of heterochromatin-associated siRNAs. By identifying small RNAs which map to other regions of structural variation in flax, the impact these regions could have on the microRNA regulated biological pathways, and association of other small RNAs mapping to these regions may be discerned and used to prioritize structural variants for further molecular investigation. Regions of the Bethune genome which may be associated with small RNAs was determined by computational prediction of microRNAs and mapping of small RNA reads from high throughput RNA sequencing. Over 25,000 miRNAs were predicted from the flax genome and Unigene database using the novoMIR plant miRNA prediction program. Of these 649 discreet miRNA gene units were identified as having potential targets among the 30,649 flax Unigenes. RNAseq provided preliminary support for 349 of the predicted miRNAs derived from novoMIR and identified an additional 1.4 million unique reads to be included in further investigations. Sequence similarity to public miRNA databases suggest that the flax transcriptome utilizes most of the conserved miRNAs among angiosperm and will likely have similar regulatory roles. Using Perl programming scripts, 44,106 PAV sites of at least 1Kb were identified between flax linseed and fiber types. 143 PAV sites were found to be associated with computationally predicted miRNAs or sRNAs identified by high-throughput sequencing.

This book was released on 2024-01-15 with total page 1630 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crop plants cater not only to our basic F5 (food, feed, fiber, fuel, and furniture) needs but also provide a number of nutraceuticals with potential nutritional, safety and therapeutic properties. Many crop plants provide an array of minerals, vitamins, and antioxidant-rich bioactive phytochemicals. Increasing incidences of chronic diseases such as cancer, diabetes and HIV, and malnutrition necessitate global attention to health and nutrition security with equal emphasis to food security. This compendium compiles results of researches on biochemical, physiological and genetic mechanisms underlying biosynthesis of the health and nutrition related nutraceuticals. It also explores the precise breeding strategies for augmentation of their content and amelioration of their quality in crop plants under all commodity categories including cereals and millets, oilseeds, pulses, fruits and nuts, and vegetables. The compendium comprise 5 sections dedicated to these 5 commodity groups and presents enumeration on the concepts, strategies, tools and techniques of nutraceutomics. These sections include 50 chapters devoted to even number of major crop plants. These chapters present deliberations on the biochemistry and medicinal properties of the nutracuticals contained; genetic variation in their contents; classical genetics and breeding for their quantitative and qualitative improvement; tissue culture and genetic engineering for augmentation of productivity and quality; and sources of genes underlying their biosynthesis. They also include comprehensive enumeration on genetic mapping of the genes and QTLs controlling the contents and profile of the nutraceuticals and molecular breeding for their further improvement through marker assisted selection and backcross breeding tools. Prospects of post-genomic precise breeding strategies including genome-wide association mapping, genomic selection, allele mining, and genome editing are also discussed. This compendium fills the gap in academia, and research and development wings of the private sector industries interested in an array of subjects including genetics, genomics, tissue culture, genetic engineering, molecular breeding, genomics-assisted breeding, bioinformatics, biochemistry, physiology, pathology, entomology, pharmacognosy, IPR, etc., and will also facilitate understanding of the policy making agencies and people in the socio-economic domain and research sponsoring agencies.

This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lectins are proteins that bind specifically to carbohydrates and are active in plant defense and other processes. The sequencing of the flax (Linum usitatissimum) genome showed that it was unusually rich in genes predicted to encode one or more agglutinin domains (PFAM PF07468). This domain is characteristic of the amaranthin-type lectin family, thus the 19 predicted flax genes were named LuALLs (Linum usitatissimum amaranthin-like lectins). To investigate their functions, transcript expression of 19 LuALLs was measured using qRT-PCR. Some LuALLs were enriched in specific tissues, such as developing seeds, while most LuALLs were expressed at various levels throughout the vegetative and floral tissues assayed. Distinct clades of LuALLs were found to be inducible by either salicylic acid or methyl jasmonate, exclusively, consistent with a role for these genes in plant defense. Preliminary hemagglutination assays with a recombinant LuALL provided evidence that members of this family function as genuine lectins.

Available in PDF, EPUB and Kindle. Book excerpt: Plants are an important source of fats and oils, which are essential for the human diet. In recent years, genomics of oil biosynthesis in plants have attracted great interest, especially in high oil-bearing plants, such as sesame, olive, sunflower, and palm. Considering that, genome sequencing projects of these plants have been undertaken with the help of advanced genomics tools such as next generation sequencing. Several genome sequencing projects of oil crops are in progress and many others are en route. In addition to genome information, advanced genomics approaches are discussed such as transcriptomics, genomics-assisted breeding, genome-wide association study (GWAS), genotyping by sequencing (GBS), and CRISPR. These have all improved our understanding of the oil biosynthesis mechanism and breeding strategies for oil production. There is, however, no book that covers the genomes and genomics of oil crops. For this reason, in this volume we collected the most recent knowledge of oil crop genomics for researchers who study oil crop genomes, genomics, biotechnology, pharmacology, and medicine. This book covers all genome-sequenced oil crops as well as the plants producing important oil metabolites. Throughout this book, the latest genomics developments and discoveries are highlighted as well as open problems and future challenges in oil crop genomics. In doing so, we have covered the state-of-the-art of developments and trends of oil crop genomics.
