[Method] First,a screening for glyphosate resistant varieties among sixty-seven wild soybean materials was done in a field trial; subsequently, physiological indexes of the screened resistant variety ZYD0685 and the sensitive variety ZYD0790 were studied. [Result]At the glyphosate dose of 1.23 kg a.i/hm2, glyphoaste resistance varied greatly among different wild soybean materials, with the highest survival rate of 87% and83% occurring in ZYD0685 and ZYD2405, respectively, and that of another seven accessions ranged from 2.7% to 38%, and all the remaining fifty-eight soybean materials died. After treatment with glyphoaste at different doses, there were no significant differences in chlorophyll content and shikimate content in the resistant ZYD0685, but there was an evident increase in the activity of gultathione-S-transferases(GSTs); while in the sensitive ZYD0790, the content of shikimic acid increased significantly, and chlorophyll content decreased significantly, and GSTs activity revealed a slight change. [Conclusion] Therefore, lowering the amount of accumulated shikimic acid is the major physiological response to glyphosate in wild soybean.展开更多

The diverse growing conditions of wild soybean in China contribute to numer- ous phenotypes of wild soybean, which also reflect the evolution process through long-term natural and artificial selection. The research progress of wild soybean germpfasms was summarized in resource status and innovative utilization in order to provide information for research of wild soybean germplasms.展开更多

China is rich in wild soybean resources. In the past 30 years, domestic scholars have carried out a large quantity of studies on the genetic diversity of wild soybean in China, which have laid the theoretical foundation for the protection and utilization of wild soybean resources. In this paper, the research progress on the genetic diversity of wild soybean in China at the phenotypic, biochemical and molecular levels of wild soybean was reviewed, and the future development of the research on the genetic diversity of wild soybean was introduced.展开更多

The transgenic roundup-ready soybean was sown in the middle of the field in a circular manner for 5 circles, with the distance of 3 m, from one circle to another. Then the wild soybean was planted in plots as the rays of the circles in 8 directions (N, E, W, S, NE, NW, SE and SW), spaced every 5 m until 50 m. Each plot comprised 25 plants. In the second year, the wild soybean seeds from the first year were planted in the field together with the original wild soybean as check. Before flowering time, high concentrations of roundups (about 4-5 times of the normal dose) were sprayed on the plants and the surviving plants were identified. The leaves were taken to the lab for DNA extraction to determine the unique DNA for roundup-ready soybean (CTAB method). About 2% of the plants survived, but some leaves were yellow. One plant of wild soybean was found to have the roundup-ready gene from the original roundup-ready soybean. The other surviving wild soybeans should also had some fragments of the roundup tolerance gene. However, the DNA bands were not very clear in the PCR map.展开更多

Merr. (G. hispida Max.), G. soja Sieb., and Zucc (G, ussuriensis Reg. and Maack); and the hybrids of their homozygous forms (F6). Representatives of the initial kinds and interspecific hybrids for reproduction were grown up in comparable conditions. Seeds of a soybean were grown up at 24℃ in Petri cups in thermostat in darkness during winter. For research of mitotic meristem cages activity the tips of roots were fixed temporal by acetoalcohol (fractional fixing) from 1 p.m. till 12 a.m., further up to 12 p.m. each 60 minutes. Acetokarmin was used for preparing the coloring. For researching of mitotic indexes, there have been analyzed from 6 up to 10 thousand cells at each stage (during each moment of time: 01 hour, 02, 03 06 ... 12, 13 ... 18 hours and further). Within a day (day + night) in cells of root apical meristem, three mitosis "waves" in each of the investigated forms with an absolute starting point of rest at 12 p.m., with precisely expressed further periodicity were found out. Each of the investigated forms misses in character of wave processes, on a degree of increase and recession of mitosis waves, on the level of mitotic indexes. Maximal mitotic activity at all the investigated forms is noted at 6 and 12 a.m. and 6 p.m.展开更多

Merr.) and G. soja Sieb. et Zucc. in comparison with parent plant species. The parent plant species and interspecific hybrids were sowed and grew under similar conditions. The similarity of the anatomic structure of stalks of cultivated plants and Glycine soja (wild soya) proves the hypothesis the studied species have the same origin. However, the obtained results show the considerable degree of phylogenetic dissociation between the studied soya species. Interspecific hybrids inherit from G. soja the ability to high intensive growth. The G. soja use in practical selective breeding is of great interest.展开更多
