“…Although Niyomdham (1992) proposed a treatment of V. grandiflora as a variety of V. radiata, AFLP distance suggests this to be a distinct species. In addition, V. trinervia of section Angulares is more closely related to V. mungo than the other section Ceratotropis species analyzed here.…”

Thailand is a center of diversity for section Angulares of the Asian Vigna (genus Vigna subgenus Ceratotropis) and 4 Vigna species are cultivated in Thailand. Using newly collected wild and cultivated germplasm of Vigna from Thailand and outgroup accessions AFLP analysis was conducted to clarify genetic diversity and relationships. The results suggest that cultivated V. umbellata and V. mungo evolved from wild relatives in a single domestication event. Vigna umbellata is poorly differentiated from its wild and weedy relatives compared to V. mungo. Results suggest northern Thailand and the neighboring Shan state, Myanmar, is the probable center of domestication for V. umbellata as wild accessions from this area and cultivated rice bean from a wide area in Asia are not greatly diverged. Vigna minima, V. tenuicaulis and V. exilis accessions in Thailand are well differentiated with considerable intra-specific variation. Vigna hirtella consists of two well differentiated subgroups, suggesting taxonomic revision may be necessary. Close genetic relationships between V. radiata and V. grandiflora, and between V. mungo and V. trinervia are confirmed. Naturally growing V. mungo populations in northern Thailand appear to be true wild species as they are well differentiated from Indian wild and Thai cultivated populations. The origin of naturally growing cowpea in Thailand needs to be further studied using a more comprehensive set of materials. This study clarifies inter and intra-specific genetic diversity and inter species relationships of Thai Vigna species.

“…Certainly, Wajira grahamiana is morphologically and ecologically the most distinctive species in the genus. Niyomdham (1992) merged Vigna grahamiana with the Asian species Dolichos junghuhnianus Benth., resulting in an entity called D. grahamianus that was widely distributed in southern and eastern Asia. However, this action was totally unjustified as D. junghuhnianus has a capitate, penicillate stigma and has nothing to do with Vigna (Wajira) grahamiana.…”

We established cell suspension cultures derived from leaf, stem, and root calli of Pueraria candollei var. candollei and P. candollei var. mirifica using liquid Murashige and Skoog (MS) medium supplemented with 0.56 lM 6-benzyladenine (BA) and 4.52 lM 2,4-dichlorophenoxyacetic acid (2,4-D). Growth of the cell suspension cultures progressed to the stationary phase within 15-24 days. Methanolic extracts of cell suspension cultures of both varieties of P. candollei were analyzed using a validated HPLC protocol. All cell lines derived from leaf, stem, and root explants produced four major isoflavonoids: daidzein, daidzin, genistein, and genistin; these isoflavonoids were detected only in the roots of intact plants. Furthermore, the isoflavonoid contents of the cell suspension cultures were higher than those of intact plants. Thus, cell suspension culture of both varieties of P. candollei may be an effective tool for isoflavonoid production.
