Network analysis of the metabolome and transcriptome reveals novel regulation of potato pigmentation

Abstract

HighlightAn integrated approach of metabolomics and transcriptomics was applied to understand regulatory networks associated with biosynthesis of anthocyanins that are differentially regulated in light-red- and dark-purple-colored potato cultivars.

Biochemical and functional characterization of AcUFGT3a, a galactosyltransferase involved in anthocyanin biosynthesis in the red‐fleshed kiwifruit (Actinidia chinensis)

“…Nonetheless, the functional critical genes, which contribute to the formation of this phenotype remain scarce. Anthocyanin biosynthesis in kiwifruit is derived from the flavonoid branch of the phenylpropanoid metabolic pathway and has been extensively studied (Crowhurst et al , Huang et al , Li et al ) as well as in Arabidopsis (Gonzalez et al ), peach (Rahim et al ), sweet cherry (Wei et al ), sweet oranges (Lo Piero ), lotus petals (Deng et al ), apple (El‐Sharkawy et al ) and potato (Cho et al ). As shown in Fig.…”

The perspectives of metabolomics studies of potato plants

“…Hongyoung имеет светлокрасную кожуру и мякоть, а клубни сорта Jayoung окрашены в темнофиолетовый цвет. Анализ данных про филирования методом PCA показал, что метаболитные профили этих сортов различаются в пространстве первых двух главных компонент (Cho et al, 2016). В частности, состав флавоноидов сильно различался у сортов Hong young и Jayoung, что свидетельствует, возможно, о реша ющей роли этих метаболитов в определении пигментации картофеля.…”

“…В частности, состав флавоноидов сильно различался у сортов Hong young и Jayoung, что свидетельствует, возможно, о реша ющей роли этих метаболитов в определении пигментации картофеля. Апигенин, кемпферол, дигидрокемпферол и производные пеларгонидина содержались в больших количествах у сорта Hongyoung, тогда как производные пеонидина, петунидина и мальвидина -у сорта Jayoung (Cho et al, 2016).…”

Combined Metabolome and Transcriptome Analyses Reveal the Effects of Mycorrhizal Fungus Ceratobasidium sp. AR2 on the Flavonoid Accumulation in Anoectochilus roxburghii during Different Growth Stages

“…Similarly, the transcriptome means the detection of all RNA transcripts in a sample and reflects gene expression differences between different treatments [29]. Integrated transcriptome and metabolome analyses have been successfully applied to study the metabolic pathways of some substances [30,31], the color formation of vegetables, fruits, and flowers [32,33], the stress resistance mechanisms [34,35], and the growth and development mechanisms of the plants [36,37]. The combination can not only elucidate changes in the content of a series of metabolites, but it can also analyze the corresponding differentially expressed genes.…”
