Metabolome and transcriptome analyses of anthocyanin biosynthesis reveal key metabolites and candidate genes in purple wheat (Triticum aestivum L.)

Abstract

Wheat (Triticum aestivum L.) is continuously subjected to genetic improvement to optimize grain quality. Purple wheat has recently gained attention because of its high anthocyanin and nutrient content. In this study, we performed an integrated transcriptome and metabolome analysis of the inbred wheat lines ZM152 (white wheat line) and ZM163 (purple wheat line) to elucidate molecular networks and identify potential genes regulating anthocyanin synthesis. A total of 564 metabolites were detected, of which 47 metabolite contents differed significantly between the two lines. Twenty-five flavonoids, including four anthocyanins, were significantly higher in purple wheat. High con-

Biregional division angles generate sharp apex and concave joints in leaves

“…T. sebifera, also known as the Chinese tallow tree, is an important member of the spurge family (Euphorbiaceae). Its oil production, leaf color changes, ecological adaptation, and genome sequence has been well studied (Liu et al, 2024;Carrillo et al, 2012;Luo et al, 2022). Despite its important economic value, research about its leaf development has been absent to date.…”

Metabolome and Transcriptome Reveal Chlorophyll, Carotenoid, and Anthocyanin Jointly Regulate the Color Formation of Triadica sebifera

“…Candidate structural genes and transcription factors associated with anthocyanin biosynthesis in T. sebifera leavesThe role of anthocyanin biosynthesis in the development of purple colouration has been extensively studied in multiple plant species, including tomato(Wang et al 2019), Tetrastigma hemsleyanum(Yan et al 2020a), Brassica(Heng et al 2020, Zhao et al 2022c, tea(Song et al 2022), and wheat(Liu et al 2023). …”
