China: RNA-sequencing analysis reveals key genes behind eggplant peel variation

Published 2024년 2월 26일

Tridge summary

A study published in Horticulture Research has identified key genes responsible for the color variation in eggplant peels. Central to this is the SmMYB113 gene, which regulates anthocyanin biosynthesis, the process that gives fruits and vegetables their red, purple, and blue colors. The research also discovered 27 new genes potentially linked to color differences, 32 new genes within the SmMYB113-regulated anthocyanin biosynthesis network, and five genes crucial for both color variation and anthocyanin accumulation. These findings could guide future genetic and breeding strategies to enhance fruit coloration.

Anthocyanins give fruits and vegetables their red, purple, and blue colors, offering health benefits. Their biosynthesis involves specific enzymes and is regulated by the MBW complex of transcription factors. Research has linked color variations in plants to anthocyanin content and structure, with transcriptomic analyses revealing genes involved in these differences.In eggplants, SmMYB113 has been identified as a key regulator of anthocyanin biosynthesis, affecting peel color. Despite progress, the precise molecular mechanisms behind color diversity in eggplants remain unclear, indicating a need for further investigation into anthocyanin biosynthesis and regulation.Horticulture Research published research titled "RNA-sequencing analysis reveals novel genes involved in the different peel color formation in eggplant."Firstly, the expression patterns of anthocyanin biosynthesis genes in eggplants of different colors and developmental stages were explored, and it was found that ...
