Transcriptomic profiling of two Pak Choi varieties with contrasting anthocyanin contents provides an insight into structural and regulatory genes in anthocyanin biosynthetic pathway.

ABSTRACT:

Background

The accumulation of anthocyanin in horticultural crops not only improves their stress tolerances but also their nutritional values. Many key regulatory and structural genes in anthocyanin biosynthesis have been identified in model plants, but limited information is available for non-model plant species featured with colored leaves. In this study, two Pak Choi varieties with green or purple leaves were selected to analyze the anthocyanin biosynthesis through RNA-Seq.

Results

A total of 2475 unigenes were differentially expressed between these tested varieties, including 1303 down-regulated and 1172 up-regulated genes in the purple-leafed one. The reliability of the RNA-Seq was further confirmed by using real-time quantitative PCR. Kyoto Encyclopedia of Genes and Ge
