Abstract:
S-adenosyl-L-met-nionine synthetase(SAMS)is a key enzyme in plant metabolize.The syntheses of S-adenosyl-L-methionine(SAM)were catalyzed by SAMS.Transgenic soybean with GsSAMS gene had a greater tolerance to saline and alkaline stress compared with non-transgenic plants.In order to scientific evaluate the variation of the main agronomic traits between transgenic soybean and the control,the yield traits,morphological traits and quality traits of transgenic soybean lines SN28-SA-1,SN28-SA-2,SN28-SA-3,SN28-SA-4 and SN28-SA-5 were investigated and analyzed.There were no obvious differences in yield traits between transgenic soybean and the control.In morphological traits,there were no obvious differences in yield traits between transgenic soybean lines SN28-SA-1，SN28-SA-2，SN28-SA-3,SN28-SA-4 and control,but the plant height of SN28-SA-5 was obvious less than control,which proved different transformation event could produce a variation of morphological traits.In quality traits,the protein contents of all the transgenic soybean lines were higher by 1.42%-2.12% compared with control,while the content of oil was not obviously different between transgenic soybean lines and the control.In conclusion,there was no negetive variation for morphological traits and quality traits in five transgenic soybean lines with GsSAMS gene,meanwhile the protein contents of all the transgenic soybean lines were higher than the contro1,so these transgenic soybean lines has good application prospects.
