Comparative transcriptome and flavonoids components analysis reveal the structural genes responsible for the yellow seed coat color of Brassica rapa L.

ABSTRACT:

Background

Seed coat color is an important horticultural trait in Brassica crops, which is divided into two categories: brown/black and yellow. Seeds with yellow seed coat color have higher oil quality, higher protein content and lower fiber content. Yellow seed coat color is therefore considered a desirable trait in hybrid breeding of Brassica rapa, Brassica juncea and Brassica napus.

Methods

Comprehensive analysis of the abundance transcripts for seed coat color at three development stages by RNA-sequencing (RNA-seq) and corresponding flavonoids compounds by liquid chromatography-tandem mass spectrometry (LC-MS/MS) were carried out in B. rapa.

Results

We identified 41,286 unigenes with 4,989 differentially expressed genes between brown se
