Book excerpt: The plastid genome has been the most important source of data for the reconstruction of plant phylogeny and taxonomic studies. With the rapid advancement of sequencing technology and bioinformatics, it has become laboratory routine work for obtaining plastid genomes (plastome), and population studies can be performed using chloroplast genome data. However, plastid genomes with specific characters such as pseudogenes, gene losses, gene duplications, gene rearrangements, widespread intra-individual polymorphisms, large-scale horizontal gene transfer, etc. have not been systematically studied. For example, plastomes of several saprophytic plants were confirmed to have lost many photosynthesis genes. The IR region of some plants decreased to several hundred base pairs, disappears completely, increased by dozens of kb, or repeat in the same direction. Most of these chloroplast structural variations are related to import plant evolution or special environmental adaptation, but their mechanisms are still unclear and effective analytical tools are lacking.

Book excerpt: Chloroplast genome structure, gene order and content arehighly conserved in land plants. We sequenced the complete chloroplastgenome sequence of Trachelium caeruleum (Campanulaceae) a member of anangiosperm family known for highly rearranged chloroplast genomes. Thetotal genome size is 162,321 bp with an IR of 27,273 bp, LSC of 100,113bp and SSC of 7,661 bp. The genome encodes 115 unique genes, with 19duplicated in the IR, a tRNA (trnI-CAU) duplicated once in the LSC and aprotein coding gene (psbJ) duplicated twice, for a total of 137 genes. Four genes (ycf15, rpl23, infA and accD) are truncated and likelynonfunctional; three others (clpP, ycf1 and ycf2) are so highly divergedthat they may now be pseudogenes. The most conspicuous feature of theTrachelium genome is the presence of eighteen internally unrearrangedblocks of genes that have been inverted or relocated within the genome, relative to the typical gene order of most angiosperm chloroplastgenomes. Recombination between repeats or tRNAs has been suggested as twomeans of chloroplast genome rearrangements. We compared the relativenumber of repeats in Trachelium to eight other angiosperm chloroplastgenomes, and evaluated the location of repeats and tRNAs in relation torearrangements. Trachelium has the highest number and largest repeats, which are concentrated near inversion endpoints or other rearrangements.tRNAs occur at many but not all inversion endpoints. There is likely nosingle mechanism responsible for the remarkable number of alterations inthis genome, but both repeats and tRNAs are clearly associated with theserearrangements. Land plant chloroplast genomes are highly conserved instructure, gene order and content. The chloroplast genomes of ferns, thegymnosperm Ginkgo, and most angiosperms are nearly collinear, reflectingthe gene order in lineages that diverged from lycopsids and the ancestralchloroplast gene order over 350 million years ago (Raubeson and Jansen,1992). Although earlier mapping studies identified a number of taxa inwhich several rearrangements have occurred (reviewed in Raubeson andJansen, 2005), an extraordinary number of chloroplast genome alterationsare concentrated in several families in the angiosperm order Asterales(sensu APGII, Bremer et al., 2003). Gene mapping studies ofrepresentatives of the Campanulaceae (Cosner, 1993; Cosner et al.,1997,2004) and Lobeliaceae (Knox et al., 1993; Knox and Palmer, 1999)identified large inversions, contraction and expansion of the invertedrepeat regions, and several insertions and deletions in the cpDNAs ofthese closely related taxa. Detailed restriction site and gene mapping ofthe chloroplast genome of Trachelium caeruleum (Campanulaceae) identifiedseven to ten large inversions, families of repeats associated withrearrangements, possible transpositions, and even the disruption ofoperons (Cosner et al., 1997). Seventeen other members of theCampanulaceae were mapped and exhibit many additional rearrangements(Cosner et al., 2004). What happened in this lineage that made itsusceptible to so many chloroplast genome rearrangements? How do normallyvery conserved chloroplast genomes change? The cause of rearrangements inthis group is unclear based on the limited resolution available withmapping techniques. Several mechanisms have been proposed to explain howrearrangements occur: recombination between repeats, transposition, ortemporary instability due to loss of the inverted repeat (Raubeson andJansen, 2005). Sequencing whole chloroplast genomes within theCampanulaceae offers a unique opportunity to examine both the extent andmechanisms of rearrangements within a phylogenetic framework. We reporthere the first complete chloroplast genome sequence of a member of theCampanulaceae, Trachelium caeruleum. This work will serve as a benchmarkfor subsequent, comparative sequencing and analysis of other members ofthis family and close relatives, with the goal of further understandingchloroplast genome evolution. We confirmed features previously identifiedthrough mapping, and discovered many additional structural changes, including several partial to entire gene duplications, deterioration ofat least four normally conserved chloroplast genes into gene fragments, and the nature and position of numerous repeat elements at or nearinversion endpoints. The focus of this paper is on analyses of sequencesat or near these rearrangements in Trachelium caeruleum. Inversions arebelieved to occur due to the presence of repeat elements subject tohomologous recombination (Palmer, 1991; Knox et al., 1993). Repeats mayfacilitate inversions or other genome rearrangements (Achaz et al.,2003), and higher incidences of repeats have been correlated with greaternumbers of rearrangements (Rocha, 2003). Alternatively, repeats mayproliferate within a genome asa result of DNA strand repair mechanismsfollowing a rearrangement event such as an inversion. Gene.

Book excerpt: The past decade has witnessed an explosion of our knowledge on the structure, coding capacity and evolution of the genomes of the two DNA-containing cell organelles in plants: chloroplasts (plastids) and mitochondria. Comparative genomics analyses have provided new insights into the origin of organelles by endosymbioses and uncovered an enormous evolutionary dynamics of organellar genomes. In addition, they have greatly helped to clarify phylogenetic relationships, especially in algae and early land plants with limited morphological and anatomical diversity. This book, written by leading experts, summarizes our current knowledge about plastid and mitochondrial genomes in all major groups of algae and land plants. It also includes chapters on endosymbioses, plastid and mitochondrial mutants, gene expression profiling and methods for organelle transformation. The book is designed for students and researchers in plant molecular biology, taxonomy, biotechnology and evolutionary biology.

Available in PDF, EPUB and Kindle. Book excerpt: It is very clear nowadays that plants offer several opportunities for basic studies, e.g. on development and embryogenesis, and that the fundamental principles laid open contribute to the development of new tools for plant breeding. Within the scope of the present publication, the editors have had to make a difficult choice from the many important subjects that have contributed to the remarkable progress of our molecular biological understanding of complex biological problems. This has resulted in review papers showing the present state of the art in genetic engineering, gene expression and its manipulation, microbe and insect interactions with plants, transposable elements and gene tagging, plant and organ development, the function and structure of the genome chloroplasts, and lipid biosynthesis. All papers have been written in such a way that they are also useful for non-experts interested in a particular field, as well as for students following courses in plant molecular biology. Besides presenting the state of the art, each paper gives some historical background to the developments in the field as well as perspectives for further basic research and applications. Because of the latter, scientists and students engaged in plant breeding will also profit from this publication.

Book excerpt: This book sheds new light on the chickpea genome sequencing and resequencing of chickpea germplasm lines and provides insights into classical genetics, cytogenetics, and trait mapping. It also offers an overview of the latest advances in genome sequencing and analysis. The growing human population, rapid climate changes and limited amounts of arable land are creating substantial challenges in connection with the availability and affordability of nutritious food for smallholder farmers in developing countries. In this context, climate smart crops are essential to alleviating the hunger of the millions of poor and undernourished people living in developing countries. In addition to cereals, grain legumes are an integral part of the human diet and provide sustainable income for smallholder farmers in the arid and semi-arid regions of the world. Among grain legumes, the chickpea (Cicer arietinum) is the second most important in terms of production and productivity. Besides being a rich source of proteins, it can fix atmospheric nitrogen through symbiosis with rhizobia and increase the input of combined nitrogen. Several abiotic stresses like drought, heat, salinity, together with biotic stresses like Fusarium wilt, Ascochyta blight, and Botrytis grey mould have led to production losses, as the chickpeas is typically grown in the harsh climates of our planet’s semi-arid regions.

Available in PDF, EPUB and Kindle. Book excerpt: Humankind has had a long and intimate association with gourds, and one of them, the bottle gourd, or calabash, may have been man's first cultivated plant. Although grown in the United States today primarily as ornamentals, in other parts of the world gourds have many other important uses. With charming text and stunning black-and-white photographs, The Gourd Book provides fascinating scientific information and folklore about these remarkable plants and keys for identifying species. The first part of the book deals with tree gourds, widely used as containers and for decoration; the Cucurbita gourds, including the buffalo gourd, the Turk's turban, the silver-seed gourd, and the Malabar gourd, all utilized as food, and the beautiful ornamental gourds; the loofah gourds, popular as cosmetic sponges; minor gourds, such as the snake, wax, bitter, teasel, and hedgehog, sometimes used as food or medicine; and gourds mentioned in the Bible. The second part takes up the bottle gourd, which has been used for thousands of years. Even today this gourd is almost indispensable in many parts of the tropics, where species are used to make containers, musical instruments, and clothing, as food and medicine, and in art. The book concludes with a discussion of the gourd in folklore and myth and an appendix on growing, hybridizing, and preserving gourds for decoration. Delightfully written for general readers, this book will also appeal to botanists, anthropologists, horticulturists, and everyone interested in plants or gardening.
