Soybean was domesticated in East Asia, where various kinds of landraces have been established as a result of adaptation to different environments and the diversification of food cultures. Asia is thus an important germplasm pool of soybean. In order to evaluate the genetic structure of the Asian soybean population, we analyzed allelic profiles at 20(More)
Soybean [Glycine max (L.) Merr.] is one of the major crops in the world and was domesticated from a wild progenitor, Glycine soja Sieb. & Zucc., in East Asia. In order to address the questions concerning the evolution and maternal lineage of soybean, we surveyed the variation in chloroplast DNA simple sequence repeats (cpSSR) of 326 wild and cultivated(More)
To identify quantitative trait loci (QTLs) conditioning salt tolerance in soybean (Glycine max (L.) Merr.), two recombinant inbred line (RIL) populations derived from crosses of FT-Abyara × C01 and Jin dou No. 6 × 0197 were used in this study. The FT-Abyara × C01 population consisted of 96 F7 RILs, and the Jin dou No. 6 × 0197 population included 81 F6(More)
Salt-affected soils are generally classified into two main categories, sodic (alkaline) and saline. Our previous studies showed that the wild soybean accession JWS156-1 (Glycine soja) from the Kinki area of Japan was tolerant to NaCl salt, and the quantitative trait locus (QTL) for NaCl salt tolerance was located on soybean linkage group N (chromosome 3).(More)
A pyramided FHB resistance line of wheat (WSY) was previously developed from three FHB resistant cultivars (Sumai 3, Wangshuibai, and Nobeokabouzu) in the Jiangsu Academy of Agricultural Sciences, China. In the present study, we analyzed the genetic relationship between WSY and the three parental cultivars using DNA markers in order to clarify how many and(More)
Diurnal patterns of gas exchange and chlorophyll (Chl) fluorescence parameters of photosystem 2 (PS2) as well as H2O2 content were analyzed in Reaumuria soongorica (Pall.) Maxim., a perennial semi-shrub. The rate of photorespiration was estimated by combined measurement of gas exchange and Chl fluorescence. The rate of photorespiration increased with the(More)
Soybean chloroplast DNAs (cpDNAs) are classified into three types (I, II and III) based on RFLP profiles. Type I is mainly observed in cultivated soybean (Glycine max), while type II and type III are frequently found in both cultivated and wild soybean (Glycine soja), although type III is predominant in wild soybean. In order to evaluate the diversity of(More)
Species of the genus Elymus are closely related to some important cereal crops and may thus serve as potential alien genetic resources for the improvement of these crops. E. humidus is indigenous to Japan and is well adapted to a humid climate. However, the phylogenetic and evolutionary relationships between E. humidus and other Elymus species are unclear.(More)
Caragana korshinskii Kom. is a perennial xerophytic shrub, well known for its ability to resist drought. In order to study ecophysiological responses of C. korshinskii under extreme drought stress and subsequent rehydration, diurnal patterns of gas exchange and chlorophyll (Chl) fluorescence parameters of photosystem II as well as Chl content were analyzed.(More)
We used AFLP analysis to explore the genetic relationship and diversity between and within 4 Mangifera species. We analyzed 35 accessions comprising 8 cultivars and 3 landraces of M. indica L., 11 landraces of M. odorata Griff., 7 landraces of M. foetida Lour., and 6 landraces of M. caesia Jack. Using 8 primer combinations produced a total of 518 bands, 499(More)
