Abstract
Endophytic filamentous actinobacteria were isolated from surface-sterilized roots of wheat plants. Endophytic colonization of germinating wheat seed was examined using one of these endophytes, Streptomyces sp. strain EN27, tagged with the egfp gene. Endophytic colonization was observed from a very early stage of plant development with colonization of the embryo, endosperm, and emerging radicle.
摘要
从经过表面消毒的小麦植株根部分离出内生丝状放线菌。使用其中一种内生菌——标记有egfp基因的链霉菌属菌株EN27，检测发芽小麦种子的内生定殖情况。在植物发育的早期阶段就观察到了内生定殖，定殖发生在胚、胚乳和胚根中。
