Abstract

The invention relates to the technical field of gene engineering, in particular to a Chinese cabbage TT2 gene family and application thereof. The gene family of Chinese cabbage transparent seed coat 2 comprises two members such as a BrTT2-1 gene and a BrTT2-2 gene, wherein the two TT2 genes have high homology. The invention further discloses application of the gene family to plant molecular breeding. After expression of the gene family in black seed cabbage type rape is subjected to antisense suppression, transgenic plants are subjected to character change such as color shallowing of seed coat and the like and potential of creating a transgenic yellow seed material is achieved.

Description

[0001] The present invention is a divisional application with the application number 201010281894.8, the application date is September 15, 2010, and the application name is "Brassica napus and its parent species Chinese cabbage and Brassica TT2 gene family and their application". technical field [0002] The invention relates to the technical field of genetic engineering, in particular to a cabbage (Brassica rapa) TT2 (TRANSPARENTTESTA2, transparent seed coat 2; also known as MYB123) gene family and applications thereof. Background technique [0003] Brassica (Brassica) is the most important genus among more than 300 genera in the Brassicaceae (Brassicacease), containing worldwide important vegetables, oilseeds and ornamental crops, such as cabbage (B.rapa), cabbage (B.oleracea) and Brassica napus (B. napus), and Brassica napus is an allotetraploid formed by natural interspecific hybridization and doubling of Chinese cabbage and Brassica napus. Arabidopsis thaliana is the mo...
