“…All PbRVE genes in Pyrus bretschneideri leaves under a light/dark cycle exhibited a circadian rhythm. The four PbRVE genes also exhibited robust rhythms under constant light conditions [ 79 ]. In plants, Arabidopsis and Oenanthe javanica grow under various photoperiodic conditions, and the expression of the clock gene Lhcb always decreases from peak levels before dusk and increases from trough levels before dawn.…”

The circadian clock refers to the formation of a certain rule in the long-term evolution of an organism, which is an invisible ‘clock’ in the body of an organism. As one of the largest TF families in higher plants, the MYB transcription factor is involved in plant growth and development. MYB is also inextricably correlated with the circadian rhythm. In this study, the transcriptome data of the tea plant ‘Baiyeyihao’ were measured at a photoperiod interval of 4 h (24 h). A total of 25,306 unigenes were obtained, including 14,615 unigenes that were annotated across 20 functional categories within the GO classification. Additionally, 10,443 single-gene clusters were annotated to 11 sublevels of metabolic pathways using KEGG. Based on the results of gene annotation and differential gene transcript analysis, 22 genes encoding MYB transcription factors were identified. The G10 group in the phylogenetic tree had 13 members, of which 5 were related to the circadian rhythm, accounting for 39%. The G1, G2, G8, G9, G15, G16, G18, G19, G20, G21 and G23 groups had no members associated with the circadian rhythm. Among the 22 differentially expressed MYB transcription factors, 3 members of LHY, RVE1 and RVE8 were core circadian rhythm genes belonging to the G10, G12 and G10 groups, respectively. Real-time fluorescence quantitative PCR was used to detect and validate the expression of the gene transcripts encoding MYB transcription factors associated with the circadian rhythm.

“…In addition, we identified four light-responsive proteins ( FKF1 , LHY , RVE1 , and RVE2 ) involved in plant circadian pathways and in the regulation of plant photosynthesis and flowering. Note that few investigations have been conducted on plant anthocyanin synthesis ( Joo et al., 2017 ; Yan et al., 2020 ; Liu et al., 2023 ). The only existing studies showed that after overexpression of RVE8 in Arabidopsis thaliana, the structural genes of the anthocyanin pathway such as 4CL were up-regulated during the day, but this up-regulation was lost at night, suggesting that RVE8 may play a specific role in the influence of light on anthocyanin biosynthesis ( Pérez-García et al., 2015 ).…”

Anthocyanins exist widely in various plant tissues and organs, and they play an important role in plant reproduction, disease resistance, stress resistance, and protection of human vision. Most fruit anthocyanins can be induced to accumulate by light. Here, we shaded the “Hong Deng” sweet cherry and performed an integrated analysis of its transcriptome and metabolome to explore the role of light in anthocyanin accumulation. The total anthocyanin content of the fruit and two of its anthocyanin components were significantly reduced after the shading. Transcriptome and metabolomics analysis revealed that PAL, 4CL, HCT, ANS and other structural genes of the anthocyanin pathway and cyanidin 3-O-glucoside, cyanidin 3-O-rutinoside, and other metabolites were significantly affected by shading. Weighted total gene network analysis and correlation analysis showed that the upstream and middle structural genes 4CL2, 4CL3, and HCT2 of anthocyanin biosynthesis may be the key genes affecting the anthocyanin content variations in fruits after light shading. Their expression levels may be regulated by transcription factors such as LBD, ERF4, NAC2, NAC3, FKF1, LHY, RVE1, and RVE2. This study revealed for the first time the possible role of LBD, FKF1, and other transcription factors in the light-induced anthocyanin accumulation of sweet cherry, thereby laying a preliminary foundation for further research on the role of light in anthocyanin accumulation of deep red fruit varieties and the genetic breeding of sweet cherry.

“…We also counted the number of differentially expressed MYB genes occured duplications, the results show that 26 gene pairs (59.09%) were identi ed. By annotation of their Arabidopsis homo genes and review of previous studies [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67], the functions of homo genes were brie y annotated. the result show that 13 duplicated genes (30.95%) of homologs are linked to ABA, 11 genes (26.19%) are linked to stress defense, 5 genes (11.90%) are linked to lignin synthesis, and 4 genes (9.52%) are linked to plant optical morphology and circadian rhythms (Table S6).…”

Besides developmental and metabolic aspects, MYB transcription factors play key roles in plant defence and stress responses. From six pearl millet genomes, 1133 MYB genes were identi ed, and four subgroups were constructed by phylogenetically. The duplication pattern of MYB genes in the pearl millet genomes has a conserved and similar evolutionary history. In abiotic stress, MYB genes have a preference for drought stress and heat stress and are more strongly regulated in roots. Multiple analyses have shown that MYB genes respond to abiotic stresses by regulating ABA-related, circadian rhythms and histone modi cation pathways. Under abiotic stress, a large number of duplication events occurred in differentially expressed genes, and the positive expression trend of duplication on PMA5G04432.1-PMA2G00728.1 was consistent across multiple stresses, suggesting that gene duplication is essential for pearl millet adaptation to abiotic stresses. This work will contribute to further studies on the MYB gene family in pearl millet and facilitate further understanding of the potential role of MYB in the regulation of abiotic stresses.
