Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

本研究通过发根农杆菌工程菌LBA1334(含有野生型pRi1855质粒和pIG121HM双元载体质粒，编码NPTⅡ基因和GUS基因)转化烟草沙姆逊，获得了具有卡那霉素抗性烟草发状根，并筛选出良好的单克隆株系，该发状根具有典型的发状根特性(多根毛、多分支、在无激素培养基上快速生长)，通过根尖压片分析，烟草发状根不具备典型的根冠；发状根中烟碱含量1.61％稍高于与天然栽培品种母体根的含量(1.5％左右)，发状根向培养液中释放烟碱，释放量最多时占总烟碱量的81.1％；在无激素的培养基上获得了再生植株。

Hormone (growth substance; plant hormone; phytohormone) One of a group of essential organic substances produced in plants.

The content of GA exhibited on imbalance in different tissue of seedling. The content of IAA, GA and ZR of male sterile lines were lower than maintainer lines to some degree, especially in the stage of archesporial and meiosis. IAA, GA and ZR are the important plant hormone which regulates lots of activity of plant. Their deficient must interfere on the development of anther and result in abortion.

在花期叶片激素含量在保持系和不育系之间变化较大，蕾期不育系的IAA、GA和ZR含量出现不同程度的亏缺，尤其是从小蕾期到大蕾期阶段，ogura不育系、改良萝卜不育系的IAA、GA和ZR含量都极显著低于保持系IAA、GA和ZR是植物体内重要的信号物质，可调节植物的多种生命活动，其亏缺影响花粉的正常发育，从而引起败育。
