Effect of transgenic drought resistant soybean on soil microbial community and beneficial microorganism

Pot culture method was used to study the effect of transgenic drought resistant soybean(TDRS) and no transgenic drought resistant soybean(NTDRS) on soil bacteria number,actinomycetes number,fungi number and two kinds of the beneficial microorganisms named trichoderma and azoto-bacter.The results showed that the soil bacteria number was significant increased and actinomycetes number decreased in rhizosphere of TDRS only at VE growth stage under normal soil water condition.Under water stress condition actinomycetes number was significant decreased only at R1 growth stage in rhizosphere of TDRS compared with that of in the normal water condition.There was no significant effect on number of bacteria,actinomycetes,fungi,trichoderma and azotobacter at R1,R4 under normal water condition and VE,R4 under water stress condition in rhizosphere of TDRS.
