wild soybean
Sampling strategy for wild soybean (Glycine soja) populations based on their genetic diversity and fine-scale spatial genetic st
      
A total of 892 individuals sampled from a wild soybean population in a natural reserve near the Yellow River estuary located in Kenli of Shandong Province (China) were investigated.
      
Spatial autocorrelation analysis revealed that the genetic patch size of this wild soybean population is about 18 m.
      
The study provided a scientific basis for the sampling strategy of wild soybean populations.
      
Genetic Variation of Wild Soybean Glycine soja Sieb.
      
Polymorphism of RAPD markers was analyzed in the wild soybean populations from the Far East region of Russia.
      
The results obtained suggest active development of genetically different groups of wild soybean.
      
Geographically isolated subpopulations showed maximum distance from the main population of wild soybean.
      
Construction of a soybean linkage map using an F2 hybrid population from a cultivated variety and a semi-wild soybean
      
This study was conducted with the objective of determining the genomic relationship between cultivated soybean (Glycine max) and wild soybean (G.
      
Nucleotide sequences of cDNAs encoding soybean glycinin B4 polypeptide were compared for three soybean cultivars and two introductions of wild soybean, G.
      
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.
      
A spontaneous mutant lacking the β-conglycinin subunits, α′, α and β, has been identified among Japanese wild soybean genetic resources.
      
All of the variants were found in wild soybean, whereas only 14 variants existed in the cultigen.
      
Both analyses indicated a considerably higher genetic diversity in the wild soybean.
      
The predominant haplotype in the cultigen may therefore have originated from a rare haplotype of the wild soybean that is presently distributed in the southern areas of Japan and China.
      
This indicated that Tibi5 type did not originate from a recent mutation event, but had spread in wild soybean from ancient times.
      
Mitochondrial DNA (mtDNA) fragments that contain cox2 and atp6 were cloned from a wild soybean (Glycine soja, accession `B09002') and from a cultivated soybean (G.
      
Mitochondrial DNA (mtDNA) fragments that contained cox2 or atp6 loci were cloned from three accessions of wild soybean (Glycine soja) in order to understand the evolutionary changes of mitochondrial genomes in the genus Glycine subgenus Soja.
      
max) and a wild soybean revealed various sites of recombination, as well as various combinations of the 5' and 3' regions, at the cox2 and atp6 loci.
