转 GmCYS 20基因毛根中根瘤菌的侵染表型分析 转基因毛根接种携带LacZ标签的根瘤菌PN28 The transgenic hairy roots were inoculated with M. loti strain PN28 that constitutively expresses a lacZ marker.根瘤菌侵染表型分为根瘤菌吸附到根毛顶端(A),侵入线进入根表皮(B),根瘤菌进入根瘤原基(C)以及成熟根瘤的形成(D)4个类别 Rhizobial infection phenotypes included 4 categories: the position of the IT tips at the root hairs (A), at epidermis (B), at the nodule primordia (C) and at the mature nodule (D). 箭头表示根瘤菌到达的部位,用于不同表型的统计Arrows indicate the characteristic features used for scoring the phenotypes. Bar=25 μm.
