35S::GmPM30在拟南芥的根系生长中表现为对ABA的敏感性降低(英文)

摘要

LEA protein,late-embryogenesis-abundant protein,is importantin response to thesalt and drought stresses in plants.Here,weidentified a cDNA full length of LEA from soybean and found that LEA enhance the ability of anti-salinity in transgenic Arabidopsis thaliana.The expression of GmPM30 increases highly under salinity,cold or ABA treatment,and enhances by certain degree under drought stress.The germination rates,primary root lengths and survival rate of GmPM30 over-expression lines are obviously higher than that of the wild-type after suffering the salinity stress.Our studies displays that GmPM30-ox apparently enhances the tolerance to salinity in Arabidopsis thaliana.
