The production of drought tolerant transgenic poplars is one of the effective ways to improve the ecological environment of arid regions.In this study,the expression of SacB gene in transgenic lines of Populus alba×P.glandulosa was analyzed by RT-PCR and the drought tolerance of those transgenic lines was evaluated by water stress trial in greenhouse.The results showed that the transcription of SacB was detected in all transgenic lines and the fructan accumulated in the leaves of those plants.The growth,bio...

杨树是重要经济树种和短轮伐期工业用材树种之一,在水土保持和维护生态环境方面发挥着重要作用.但大多数杨树品种抗旱性较差,难以在干旱地区发挥其高产潜力.基因工程技术的发展和成熟成为短时间内培育抗旱转基因杨树的有效途径.转抗旱基因植物的研究主要集中在烟草(Nicotiana t
