The Halophyte S. portulacastrum L. living in seaside is a kind of high-salt and drought-tolerant plant. In this report, the expression and the salt-tolerant analysis of the three genes SRTG152-Ⅰ, SRTG152-Ⅱ and SRTG152-Ⅲ (GenBank: FJ457924, FJ457925 and FJ457926) isolated from salt stressed SSH bank have been researched in E. coli by inserting them into a vector pET-22b(+). The expressing proteins were obtained after inducing 3 h with 1 mmol/L IPTG at 37℃. The analysis of their salt tolerances showed that al...
高浓度盐离子胁迫和渗透胁迫,致使植物生长速率和光合作用等生理过程减慢并导致植物死亡(Hasegawa and Bressan,2000)。盐生植物能通过调节渗透压,或区域化盐离子来适应盐渍生境(赵可夫,1997,植物生理学通讯,33(6):501-502)。盐生植物海马齿(Sesuvium portulacastrumL.)常年生?
