The infection of rhizobia to rice was a dynamic process beginning with surface colonization of the rhizoplane (especially at lateral root emergence), followed by endophytic colonization within roots, and then ascending endophytic migration into the stem base, leaf sheath, and leaves where they developed high populations.

同时，根瘤菌还可以沿植物的表面从根到地上部分迁移。在植物的生殖生长阶段，内生根瘤菌仍然保持活动性，可以进入烟草子房的子房壁、胎座和胚珠内，暗示根瘤菌通过种子向子代垂直传播的可能性。

By removed ovary culture after positive and negative hybridization, produced interspecific hybridization, and have improved the hybrid seed through removed ovary culture and induced to shoot by culture medium MS, and produced hybrid F1, the plant of Brassica junce×B.pekinesis, the advantage characteristic of hybrid plant is similar to female nature;By cytology authenticating, chromosome number of F1 young flower bud cell (2n=28), it is the sum of monoploid chromosome number of female parent Brassica junce(2n=36) and male parent B.pekinesis(2n=20); The hybridization to Brassica junce×B.pekinesis, and embryonic bud come from removed ovary culture, and it found another form of plant embryo saving.
