“…Those results indicated that both auxin and ethylene have positive and negative regulation roles in the anthocyanin signal pathway; auxin is presented as an enhancement at low concentrations but is inhibitory at high concentrations. Anthocyanin accumulation has been demonstrated in rice, ornamental cabbage, and wheat after ABA treatment [40][41][42]. Cytokinin (CTK) can enhance the induction effect of light and can promote anthocyanin accumulation in the aleurone layer.…”

The color of the pericarp is a crucial characteristic that influences the marketability of papaya fruit. Prior to ripening, normal papaya exhibits a green pericarp, whereas the cultivar ‘Zihui’ displays purple ring spots on the fruit tip, which significantly affects the fruit’s visual appeal. To understand the mechanism behind the formation of purple pericarp, this study performed a thorough examination of the transcriptome, plant hormone, and metabolome. Based on the UPLC-ESI-MS/MS system, a total of 35 anthocyanins and 11 plant hormones were identified, with 27 anthocyanins and two plant hormones exhibiting higher levels of abundance in the purple pericarp. In the purple pericarp, 14 anthocyanin synthesis genes were up-regulated, including CHS, CHI, F3H, F3′5′H, F3′H, ANS, OMT, and CYP73A. Additionally, through co-expression network analysis, three MYBs were identified as potential key regulators of anthocyanin synthesis by controlling genes encoding anthocyanin biosynthesis. As a result, we have identified numerous key genes involved in anthocyanin synthesis and developed new insights into how the purple pericarp of papaya is formed.

“…As an important plant hormone, ABA can not only induce resistance to stress in crops but also improve yield, quality, even seed dormancy and seed germination [46]. Numerous studies have found that ABA-signaling pathway plays a vital role in plant responses to stresses such as drought, high salt conditions, low temperatures and invasion by pests or pathogens [12,25,42,44,48,49]. Under stressful conditions, ABA synthesis is activated in plants, resulting in the abundant production of this hormone.…”

NAC transcription factors play a significant role in plant stress responses. In this study, an NAC transcription factor, with a CDS of 792 bp encoding 263 amino acids, was cloned from Fagopyrum tataricum (L.) Gaertn. (F. tataricum), a minor cereal crop, which is rich in flavonoids and highly stress resistant. The transcription factor was named FtNAC10 (NCBI accession number: MK614506.1) and characterized as a member of the NAP subgroup of NAC transcriptions factors. The gene exhibited a highly conserved N-terminal, encoding about 150 amino acids, and a highly specific C-terminal. The resulting protein was revealed to be hydrophilic, with strong transcriptional activation activity. FtNAC10 expression occurred in various F. tataricum tissues, most noticeably in the root, and was regulated differently under various stress treatments. The over-expression of FtNAC10 in transgenic Arabidopsis thaliana (A. thaliana) seeds inhibited germination, and the presence of FtNAC10 enhanced root elongation under saline and drought stress. According to phylogenetic analysis and previous reports, our experiments indicate that FtNAC10 may regulate the stress response or development of F. tataricum through ABA-signaling pathway, although the mechanism is not yet known. This study provides a reference for further analysis of the regulatory function of FtNAC10 and the mechanism that underlies stress responses in Tartary buckwheat.

“…The bZIP family, one of the largest transcription factor families in plants, is involved in physiological processes such as plant development, environmental signaling, and stress responses (Djamei et al, 2007;Liu C. C. et al, 2018;Xiao et al, 2021). The bZIP transcription factor HY5 is an important transcription factor involved in light signal transduction and plant pigment accumulation in response to light (Holm et al, 2002;Stracke et al, 2010;Shin et al, 2013;Gangappa and Botto, 2016).…”

The perilla anthocyanins have important medicinal and ornamental value, and their contents are significantly affected by light intensity. In view of their molecular mechanisms were not well understood, we integrated the metabolomic and transcriptomic analyses of the light-sensitive perilla variety under different light intensity. The perilla leave color were obviously affected under different treatments. Totally 140 flavonoid metabolites and 2461 genes showed steady change, among which 60 flavonoid metabolites were increased accumulation and 983 genes were upregulated expression under elevated light intensity treatment. Light treatment prominently affected the expression of genes involved in the main anthocyanin metabolites accumulation in perilla leaves. Using WGCNA analysis, we identified 4 key genes in anthocyanin biosynthesis pathway (CHI, DFR, and ANS) and 147 transcription factors (MYB, bHLH, bZIP, ERF, and NAC) involved in malonylshisonin biosynthesis. Among them, 6 MYBs and 4 bZIPs were predicted to play important roles in light regulation of malonylshisonin biosynthesis based on phylogenetic construction, correlation analysis, cis-acting element identification and qPCR verification. The identified key genes and regulatory factors will help us to understand the potential mechanism of photo-regulated anthocyanin accumulation in perilla.
