Abstract

The invention discloses cabbage-type rape as well as parent species Chinese cabbage and cabbage TT8 gene families and applications thereof, wherein, the Chinese cabbage TT8 gene family comprises a BrTT8-1 gene (SEQ ID No.1-2) and a Br TT8-2 gene (SEQ ID No.3-4); the cabbage TT8 gene family comprises a BoTT8-1 gene (SEQ ID No.5-6) and a BoTT8-2 gene (SEQ ID No.7-8); the cabbage-type rape TT8 gene family comprises a BnTT8-1 gene (SEQ ID No.9-10) and a BnTT8-2 gene (SEQ ID No.11-12). The above gene families can be used for molecule breeding of the brassica crop seed properties.

Description

technical field [0001] The invention relates to the technical field of genetic engineering, in particular to Brassica napus and its parent species Chinese cabbage (Brassica rapa) and cabbage (Brassica oleracea) TT8 (TRANSPARENT TESTA8, transparent seed coat 8; also known as bHLH42, BASIC HELIX- LOOP-HELIX42, basic helix-loop-helix 42) gene family and its application. Background technique [0002] The genus Brassica (Brassica) of the Brassicaceae (Brassicaceae) includes many oil crops, vegetables and ornamental plant species. It provides humans with nutritious edible oils, vegetables and ornamental plants, and provides feed for animal husbandry. It has an important economic value. Among the Brassica species, the allotetraploid species Brassica napus was formed from two diploid species Brassica oleracea and Brassica oleracea through interspecific hybridization followed by remultiplication. Brassica napus is the second largest oil crop in the world, widely planted all over t...
