An efficient regeneration and transformation system was established and optimized for adzuki bean (Vigna angularis Willd.Ohwi & Ohashi).6-Benzylaminopurine at 5 mg l-1 was used to increase adventitious bud induction frequency.The highest frequency of shoot elongation was 92.8% when using a medium composition of MS salts combined with 0.1 mg l-1 IAA, 0.5 mg l-1 GA3, 1.0 mg l-1 zeatin-fiboside, 50 mg l-1 aspartic acid and 50 mg l-1 glutamic acid.In vitro rooting was 100% when shoots were cultured on the solid MS medium supplemented with 1.0 mg l-1 NAA.Reproducible transformation of epicotyl explants was developed using the A.tumefaciens EHA105 strain.Using a concentration of 40 mg l-1 acetosyringone, 20 mM MES and 5 mg l-1 6-benzylarninopurine in co-cultivation medium a transformation efficiency of 12.6% was attained.Using this transformation protocol, we obtained transgenic adzuki bean plants resistant to soybean mosaic virus by introducing the V.angularis VaPR3 gene.

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
