Plant Male Sterility Induced by Anti-Gene CYP86MF in Brassica oleracea var. italica

摘要

An anti-gene CYP86MF was introduced into hypocotyls of broccoli (Brassica oleracea L.var. italica Plenck) with Agrobacterium tumefaciens, and the transgenic plants were obtained by kanamycin selection. The results of PCR, Southern blot and Northern blot indicated that the anti-CYP86MF has been integrated into chromosome of the transgenic plant. And also, plants with hypogenetic stamina or ungerminated pollen were observed. The transgenic male sterility plant could fructify via artificial pollination with normal pollen. Thus it was proved that the pistil of male sterility plant was normally developed, and the sterility originated from anti-CYP86MF.
