Bean pyralid (BP; Lamprosema indicata Fabricius) is one of the major leaf-feeding insects that affect soybean crops in central and southern China. Four recombinant inbred line populations (KY, WT, XG and SX) were tested during 2004–2006 in Nanjing, China, to identify quantitative trait loci (QTL) for resistance to BP on the basis of data for rolled leaflet(More)
Annual wild soybean (Glycine soja Sieb. et Zucc.) is believed to be a potential gene source for future soybean improvement in coping with the world climate change for food security. To evaluate the wild soybean genetic diversity and differentiation, we analyzed allelic profiles at 60 simple-sequence repeat (SSR) loci and variation of eight morph-biological(More)
Association mapping (AM) combined with linkage mapping (LM) was executed to identify molecular markers and QTL regions associated with aluminum (Al) tolerance using relative root elongation (RRE) in hydroponics as an indicator. A set of 188 soybean cultivars released in Yellow and Changjiang River Valleys and 184 recombinant inbred lines (RIL) derived from(More)
The relative importance of various types of quantitative trait locus (QTL) conferring oil content and its fatty acid components in soybean seeds was assessed through testing a recombinant inbred line (RIL) population (derived from KF1 × NN1138-2) in randomized blocks experiments in 2004–2006. The contents of oil and oleic, linoleic, linolenic, palmitic and(More)
Determining mitochondrial genomes is important for elucidating vital activities of seed plants. Mitochondrial genomes are specific to each plant species because of their variable size, complex structures and patterns of gene losses and gains during evolution. This complexity has made research on the soybean mitochondrial genome difficult compared with its(More)
A representative sample comprising 366 accessions from the Chinese soybean landrace population (CSLRP) was tested under four growth environments for determination of the whole-genome quantitative trait loci (QTLs) system of the 100-seed weight trait (ranging from 4.59g to 40.35g) through genome-wide association study (GWAS). A total of 116 769 single(More)
To investigate the genetic mechanism of Al-tolerance in soybean, a recombinant inbred line population (RIL) with 184 F(2:7:11) lines derived from the cross of Kefeng No.1 x Nannong 1138-2 (Al-tolerant x Al-sensitive) were tested in pot experiment with sand culture medium in net room in Nanjing. Four traits, i.e. plant height, number of leaves, shoot dry(More)
Ariadne (ARI) subfamily of RBR (Ring Between Ring fingers) proteins have been found as a group of putative E3 ubiquitin ligases containing RING (Really Interesting New Gene) finger domains in fruitfly, mouse, human and Arabidopsis. Recent studies showed several RING-type E3 ubiquitin ligases play important roles in plant response to abiotic stresses, but(More)
The short petiole trait is valuable to ideotype breeding for yield. In this study, short petiole and abnormal pulvinus of two mutant lines NJ90L-1SP and D76-1609 were genetically investigated. These two mutants were crossed with each other and with five long petiole and normal pulvinus genotypes. Genetic analysis indicated that short petiole in NJ90L-1SP(More)
It is well accepted that somatic embryogenesis serves a primary role in plant regeneration. However, it is also a model system to explore the regulatory and morphogenetic events in the life of a plant. To date, a suite of genes that serve important roles in somatic embryogenesis have been isolated and identified. In the present study, a novel gene(More)
