稗草生防潜力菌Helminthosporium gramineum f. sp. echinochloae的原生质体制备和再生
Acta Agriculturae Zhejiangensis（2010）
Abstract
禾长蠕孢菌(Helminthosporium gramineum f. sp. echinochloae,HGE)是稗草生防潜力菌,为建立HGE的遗传转化体系,研究了菌龄、胞壁降解酶、稳渗剂等对其原生质体制备和再生的影响。结果表明,HGE菌原生质体制备的适宜条件为:26℃下采用1.0%崩溃酶处理菌龄为6h的HGE菌丝体2h,0.7mol/LNaCl为稳渗剂。原生质体再生的适宜条件为:32℃下采用0.5%崩溃酶处理菌龄为16h的HGE菌丝体4h,0.7mol/LNaCl为稳渗剂,R1为高渗再生培养基。
