[Effects of glyphosate-resistant transgenic soybean on soil rhizospheric bacteria and rhizobia.].

Transgenic soybean is the most widely grown genetically modified crop in the world, with herbicide resistance being the major modified trait. Microbial community is one of the most important indicators for soil quality. The effects of glyphosate-resistant transgenic soybean and glyphosate application on rhizospheric bacteria and rhizobia still remained unknown.

Improvement of Glyphosate Resistance through Concurrent Mutations in Three Amino Acids of the sp. 5-Enolpyruvylshikimate-3-Phosphate Synthase.

Glyphosate inhibits the target enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in the shikimate pathway. A mutant of EPSPS from sp. was identified using site-directed mutagenesis (SDM).

[Identification and genetic study of major genes of resistance to Cerospora Sojina Hara in soybean].

Soybean frogeye leaf spot is one of the main diseases in Heilongjiang province. Usually, under several physical races of Cerospora Sojina Hara existed condition, the inheritance of resistance to this disease is controlled by equal-effect polygene. While high resistant parent 'Dongnong 9674 and other sensitive parents were used to make the three resistance-sensitive combinations in this paper, the resistance to Cerospora Sojina Hara had appeared the significant major gene effect.
