This book was released on 2013-11-09 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common bean (Phaseolus vulgaris L. ) is the most important pulse crop in the world. It is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. It complements cereals and other carbohydrate-rich foods in providing near-perfect nutrition to people of all ages. Moreover, a regular intake ofbeans helps lower cholesterol and cancer risks. Despite the fact that per capita consumption of common bean in some developed countries (e. g. , the U. S. A. ) has been increasing over the last several years, in general, the average global per capita consumption is declining because production is unable to keep up with the population growth. Moreover, increasing demand for pesticide-free food products, concern for natural resources conservation, and the need to reduce production costs offer daunting challenges to the twenty-first century policy makers, bean growers, and researchers alike. High yielding, high quality bean cultivars that require less water, fertilizers, pesticides, and manual labor combined with integrated management of abiotic and biotic stresses will have to be developed. Eminent bean researchers were invited to contemplate these issues, prepare a state-of-the-art account on most relevant topics, and offer their insight into research directions into the twenty-first century. Four excellent books have been published covering various aspects ofthe common bean since 1980. These books are: I) Bean Production Problems nd in the Tropics (l SI ed. 1980, 2 ed. 1989), H. F. Schwartz & M. A.

Download or read book The Host-pathogen Interaction and Breeding and Genetics of Resistance for Common Bacterial Blight of Common Bean (Phaseolus Vulgaris L.) Caused by Xanthomonas Campestris Pv. Phaseoli and X. C. Pv. Phaseoli Var. Fuscans written by Robert Wayne Duncan and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli Smith (Dye) (Xcp, synonym: X. axonopodis pv. phaseoli [Smith] Vauterin et al.) and X. c. pv. phaseoli var. fuscans (Burkholder) Starr & Burkholder (Xcpf, synonym: X. fuscans subsp. fuscans sp. nov.) is the most important bacterial disease of common bean (Phaseolus vulgaris L.). Host resistance is the best method of management for this seed-borne disease. The first objective of this research was a host-pathogen diversity study, where new Xcp and Xcpf genotypes associated with CBB in Wisconsin were identified. These new genotypes, along with five previously reported genotypes, were inoculated onto 27 common bean genotypes having different combinations of CBB resistance QTL and markers. Eight host genotypes were identified that were resistant to all pathogen genotypes. The second objective was to compare direct disease selection (DDS) with marker-assisted selection (MAS) for the development of CBB resistant breeding lines, and the cost-effectiveness of the two selection methods. More CBB-resistant breeding lines were generated with DDS under conditions of high disease pressure in the greenhouse. However, under moderate disease pressure in the field, there were no significant differences between the two selection techniques. Under the parameters of this study, DDS was more cost-effective than MAS. Finally, the relationship between flower and seed color, CBB resistance, a CBB resistance SCAR marker (BC420) and the SOD12490 marker associated with the V pigmentation locus was investigated. In an F2 population and in the F3 progeny test, no recombination was found between colored flowers (purple [P] and lilac [L]), a dark undesirable DRK seed coat color and presence of the BC420 marker. All plants in the F2 and F3 that lacked the BC420 marker had white/lilac-striped (wl) flower color and the desirable DRK seed color. The SOD12490 marker was not linked with CBB resistance. Some plants with wl flowers were resistant but lacked the BC420 marker, indicating unidentified QTL in the CBB-resistant donor germplasm (VAX 3, Wilkinson 2, or I9365-25). Together, this information will facilitate the improvement of CBB resistance in all market classes of common bean.
Book Synopsis The Development of a Niemann-Pick Gene-based Marker in Common Bean (Phaseolus Vulgaris L.) for the Selection of Common Bacterial Blight Resistance by : Emily Morneau

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Common bacterial blight (CBB) is a major disease in common bean (Phaseolus vulgaris) caused by Xanthomonas axonopodis pv. phaseoli and Xanthomonas fuscans subsp. fuscans. By characterizing alleles in three candidate genes within white bean line OAC Rex, a codominant molecular marker for resistance was created. The Niemann-Pick polymorphism (NPP) marker was developed to screen common beans for CBB resistance, and is anchored in a candidate resistance gene (Niemann-Pick like gene). Individuals in two segregating populations were screened for allelic state and disease susceptibility. It was found that the NPP marker is significantly more efficient (8% decrease in error rate) in comparison to other markers. Within the OAC Rex pedigree, the resistant allele for the NPP marker was found solely within progeny from the introgression of Phaseolus acutifolius into P. vulgaris. Lastly, the two additional candidate resistance genes investigated (R-genes 231733-8-004 and 231733-8-005), were found to have no exploitable polymorphisms.

Available in PDF, EPUB and Kindle. Book excerpt: The edited book covers all major and minor diseases in grain legumes (chickpea, pigeon pea, lentil, mung bean, common bean, groundnut, and soybean) and forages legumes (including Medicago, rice bean, and faba bean) and their control measures by using various breeding approaches. Grain legumes are versatile nutritionally rich crops, and are one of the important components of global food security. However, grain legumes are severely challenged by various major and emerging minor diseases causing serious limitations in grain yield and production. Thus, to minimize the negative impact of the growing yield loss caused by these diseases, several approaches have been developed and embraced. This book covers all the latest development in genetics, breeding, genomics, and molecular biology tools for combating various major and minor emerging diseases in all the grain legumes from expert authors. Chapters in this title contain all the relevant illustrations and statistical data detailing the present scenario and identifying the gap for meeting the future demand for sustaining global protein security by developing disease-resistant cultivars. This book is of interest to graduate and postgraduate students, researchers, and policymakers to understand the impacts of various diseases on yield loss in legume crops.

Download or read book Breeding for Bruchid Resistance in Common Bean (Phaseolus Vulgaris L) written by Paul Mbogo Kusolwa and published by . This book was released on 2007 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility for the lines to reproduce without assistance. The inheritance of a 33 kDa seed storage protein from accession G40199 was studied in an F2 intraspecific population from a cross of G40199 and a cultivated Brown Tepary accession. G40199 possessed the protein but Brown Tepary did not. The protein was inherited as a single dominant gene in a F2 population of 116 individuals. Following these observations, interspecific hybrids were progeny tested for the introgression of a 33 kDa protein from accession G40199. Backcross interspecific introgression lines were used as bridge parents to transfer the 33 kDa protein into the large red seeded cultivar Rojo adapted to Tanzania, and into a phaseolin null backcross breeding line of Rojo with the objective of introgressing resistance to A. obtectus into a Sub-Saharan Africa variety. Genomic, proteomic and phylogenetic characterization of genes associated with the 33 kDa proteins were conducted in order to identify the mechanism of resistance found in accession G40199. Genomic DNA encoding a family of lectin-like seed storage proteins (the complex APA locus) was amplified by PCR using primers for arcelin, phytohaemagglutinin and alpha amylase inhibitors. The PCR products were used as molecular markers and co-segregated with the 33 kDa protein. Analyses of mRNA expression identified two arcelin variants, ARL-3[superscript pa] and ARL-4[superscript pa], as expressed in G40199 and its derived interspecific hybrids. MS-MS proteomic analysis of seed protein profiles in G40199 demonstrated the presence of protein peptides with amino acid sequences corresponding to the two arcelin variants and phytohaemagglutinin (PHA) protein subunits. Essentially similar protein peptides were observed in the introgression lines. Phylogenetic analysis demonstrated the difference of the two arcelin variants in G40199 that clustered with P. acutifolius arcelin-like proteins and were separated from those of P. vulgaris. Seeds from G40199 and BC2F3 interspecific hybrid lines were subjected to an A. obtectus feeding trial at OSU. Introgression lines expressing the homozygous 33 kDa protein demonstrated significant bruchid resistance. This resistance was exhibited as delayed insect emergence with a mean of 63 days for 50% F1 adults after inoculation compared to 44 days to 50% adult for ICA Pijao. In addition, reduced size and weight of adults, and reduced number of adults was observed in a period of 72 days after bruchid infestation. G40199 was completely resistant with no emerging adults. The 33 kDa protein which is linked to co-expression of ARL-3[superscript pa], ARL-4[superscript pa] and PHA protein subunits is a contributing factor to the observed resistance to A. obtectus among interspecific hybrids.
Book Synopsis Bacterial Blights of Common Bean by : Michael Lennon O'Leary
Download or read book Bacterial Blights of Common Bean written by Michael Lennon O'Leary and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Common bean is a genetically diverse crop that is a staple food in many regions of the world. However, common bean is affected by numerous diseases that can negatively impact production. There are three major bacterial diseases of common bean: halo blight, caused by Pseudomonas syringae pv. phaseolicola (Psp), bacterial brown spot, caused by P. syringae pv. syringae (Pss), and common bacterial blight, caused by Xanthomonas axonopodis pv. phaseoli (Xap) and X. fuscans subsp. fuscans (Xff). Disease symptoms caused by Psp and Pss can be difficult to distinguish in certain common bean genotypes and under certain environmental conditions. Precise pathogen identification is important in terms of potential yield loss and the need for disease management. Symptoms with characteristics of both halo blight and bacterial brown spot were observed on a newly developed cultivar of dark red kidney beans in Wisconsin, and pseudomonads were recovered from all samples. To determine the etiology of this disease, a method of identification was developed that involved 1) PCR with primers specific for toxin genes utilized by Psp and Pss, 2) the ability to induce a hypersensitivity response in tobacco leaves, and 3) symptoms induced on common bean. When applied to the unusual disease phenotype on this dark red kidney variety most of these were atypical symptoms of halo blight. This method was then successfully applied to identify bacterial brown spot in disease samples from Oregon, and halo blight and bacterial brown spot in disease samples from Turkey. Xap and Xff strains induce identical symptoms on common bean but are genetically distinct species. Strains of Xap and Xff can be differentiated in culture by the production of a brown diffusible pigment by Xff strains. However, some Xap strains, particularly those that originate from East Africa, are more genetically related to Xff strains than to the globally predominant Xap strains, and show pathogenic variability on certain cultivars, e.g., Andean versus Middle American. To better understand the genetic diversity among Xap and Xff strains, the complete genome sequences of three globally predominant Xap strains, two East African Xap strains, three Xff strains, and one Xanthomonas spp. strain that is associated with common bean but not pathogenic were determined using long-read sequencing technology. Whole-genome alignment revealed differences in chromosome organization between Xap strains, East African Xap strains, and Xff strains; additionally, mobile element content is variable among these strains. Conserved genetic factors, e.g. conserved plasmids and type III secreted effector proteins, some of which may have been horizontally acquired by Xap and Xff strains, were identified. The brown diffusible pigment produced by Xff strains is the result of an oxidation product of homogentisic acid, which is referred to as pyomelanin. In the tyrosine catabolism pathway, homogentisic acid is produced by 4-hydroxyphenylpyruvate dioxygenase (HPPD) and converted to 4-maleylacetoacetate by homogentisate dioxygenase (HmgA). The complete genome sequences of Xap and Xff strains revealed that Xff strains have a conserved mutation in the hmgA gene, whereas Xap strains have an intact hmgA gene. HPPD deletion mutants in an Xff strain resulted in loss of pyomelanin (brown pigment) production, whereas deletion of hmgA in two Xap strains resulted in brown pigment production, making Xap colonies resemble those of wild-type Xff strains. Additionally, complementing a wild-type Xff strain with a functional hmgA gene eliminated visible pyomelanin accumulation. Finally, virulence of a Xff HPPD and a Xap hmgA deletion mutant was assessed on twelve bean cultivars, including both Andean and Middle American gene pools, with different levels of disease resistance to common bacterial blight. There was no significant differences in virulence between brown pigment mutants and wild-type strains.
