Diversity of salt tolerance in , wild related species of the azuki bean ().

is a wild species closely related to the azuki bean (), with salt-tolerance abilities. The present study aimed to explore the genetic and salt tolerance diversity within the species, by evaluating the phylogenetic relationships of 55 accessions of including 25 newly collected from the Gotō Islands and Iki in Nagasaki Prefecture, Japan. We conducted salt-tolerance analysis for 48 of the accessions, including 18 of the newly collected accessions.

Unique Salt-Tolerance-Related QTLs, Evolved in (Na Includer) and (Na Excluder), Shed Light on the Development of Super-Salt-Tolerant Azuki Bean () Cultivars.

Wild relatives of crops have the potential to improve food crops, especially in terms of improving abiotic stress tolerance. Two closely related wild species of the traditional East Asian legume crops, Azuki bean (), "Tojinbaka" and "Ukushima" were shown to have much higher levels of salt tolerance than azuki beans. To identify the genomic regions responsible for salt tolerance in "Tojinbaka" and "Ukushima", three interspecific hybrids were developed: (A) azuki bean cultivar "Kyoto Dainagon" × "Tojinbaka", (B) "Kyoto Dainagon" × "Ukushima" and (C) "Ukushima" × "Tojinbaka".

Same Locus for Non-shattering Seed Pod in Two Independently Domesticated Legumes, and .

Loss of pod shattering is one of the most important domestication-related traits in legume crops. The non-shattering phenotypes have been achieved either by disturbed formation of abscission layer between the valves, or by loss of helical tension in sclerenchyma of endocarp, that split open the pods to disperse the seeds. During domestication, azuki bean () and yard-long bean ( cv-gr.

is one of the closely related species of (Adzuki bean). Two strain of 'Ukushima' and 'G418' were identified as salt tolerance strains in from gene bank collection. F populations from an inter- or intra-specific cross between the sensitive and tolerant strains are useful for the detection of salt tolerance QTL in .

Reciprocal translocation identified in Vigna angularis dominates the wild population in East Japan.

Using an F2 population derived from cultivated and wild azuki bean, we previously detected a reciprocal translocation and a seed size QTL near the translocation site. To test the hypothesis that the translocation in the cultivated variety contributed to the larger seed size, we performed further linkage analyses with several cross combinations between cultivated and wild azuki beans. In addition, we visually confirmed the translocation by cytogenetic approach using 25 wild and cultivated accessions.

Detection of genome donor species of neglected tetraploid crop Vigna reflexo-pilosa (créole bean), and genetic structure of diploid species based on newly developed EST-SSR markers from azuki bean (Vigna angularis).

Vigna reflexo-pilosa, which includes a neglected crop, is the only one tetraploid species in genus Vigna. The ancestral species that make up this allotetraploid species have not conclusively been identified, although previous studies suggested that a donor genome of V. reflexo-pilosa is V.

Construction of a genetic linkage map and genetic analysis of domestication related traits in mungbean (Vigna radiata).

The genetic differences between mungbean and its presumed wild ancestor were analyzed for domestication related traits by QTL mapping. A genetic linkage map of mungbean was constructed using 430 SSR and EST-SSR markers from mungbean and its related species, and all these markers were mapped onto 11 linkage groups spanning a total of 727.6 cM.

The genetics of domestication of rice bean, Vigna umbellata.

Background And Aims: The Asian genus Vigna, to which four cultivated species (rice bean, azuki bean, mung bean and black gram) belong, is suitable for comparative genomics. The aims were to construct a genetic linkage map of rice bean, to identify the genomic regions associated with domestication in rice bean, and to compare these regions with those in azuki bean.

Methods: A genetic linkage map was constructed by using simple sequence repeat and amplified fragment length polymorphism markers in the BC(1)F(1) population derived from a cross between cultivated and wild rice bean.

Mapping of quantitative trait loci for a new source of resistance to bruchids in the wild species Vigna nepalensis Tateishi & Maxted (Vigna subgenus Ceratotropis).

Azuki bean breeders have long been interested in producing azuki bean [Vigna angularis (Willd.) Ohwi & Ohashi] varieties with bruchid resistance. A new bruchid (Callosobruchus spp.

Genome dissection of traits related to domestication in azuki bean (Vigna angularis) and comparison with other warm-season legumes.

Background: The objective of this study was to dissect into quantitative trait loci (QTLs) the large morphological and physiological differences between cultivated azuki bean (Vigna angularis) and a wild relative and to infer the commonalities of the QTLs for domestication-related traits across the Asian Vigna and with other warm-season legumes.

Methods: Two linkage maps, for the BC(1)F(1) and F(2) populations, respectively, from the same cross between azuki bean and V. nepalensis were developed.
