Expression of foreign gene in plants is affected by many factors, such as the insertion site, copy numbers, the extemal environment et al.In applications, however, the popular topic is whether the expression of foreign genes can achieve the desired results.The artificially modified foreign genes of Cry1Ab/Ac and CpTI were transferred to cotton that is the most important cash crop in China, and were commercialization and industrialization of development.

花生在整个生育时期会遭受到各种环境胁迫,其中温度就是影响花生生长发育的重要因素之一.花生播种后常遭遇低温威胁,这种灾害的发生生理表现为:生长缓慢,代谢弱,根系吸水减少,蒸腾作用减弱,植株单位时间内的生物量小,最终导致产量的降低.花生在我国种植范围较广泛,北方已种植到黑龙江省黑河市(北纬50°).

由Ralstonia solanacearum引起的花生青枯病是我国花生上的一种毁灭性病害.通过轮作、化学药剂和生物防治能够在一定程度上预防青枯病的发生,但是这些方法浪费土地资源,并且增加了种植成本.选育和种植抗青枯病花生品种是目前最为经济有效的防治途径.花生栽培种基因组庞大,且含有较多重复序列.虽然近年来有不少关于花生青枯病抗性基因分子标记的报道,但是这些分子标记与抗性间的图距较大,实用价值不大
橡胶是我国的重要物质.巴西橡胶树是一种重要的产胶植物,也是我国热带、亚热带地区重要的经济作物.用分子标记方法构建橡胶树的连锁群或遗传图谱难度大,现有的橡胶树连锁遗传图少而且是从总基因组中获得,并有连锁群不稳定,连锁标记少且分布不均匀,无法确定许多重要基因在染色体上的位置和分布特点.构建橡胶树单染色体文库,可以有效的解决上述问题.本实验以巴西橡胶树热研7-33-97幼叶为材料,采用酶解去壁低渗法,建
