“…The expression of UFGT was the highest at 0MS (Figure 6g), and the other treatments had little effect on UFGT. It was established that nutrient deficiency is a key factor that can induce significant anthocyanin accumulation in plants, with the concomitant upregulation of genes being responsible for anthocyanin synthesis, as reported by Li et al [55]. In this experiment, the expressions of PAL, CHS, CHI, and DFR showed similar trends to the anthocyanin content.…”

Red pears are appreciated for their abundant nutritional benefits and visually striking red hue, rendering them a favored option among consumers and stimulating substantial market demand. The present study employs the flesh of a red pear as the explant, subjecting the flesh callus to varying sugar sources, MS concentrations, light qualities, and temperatures to investigate the alterations in secondary metabolites, including anthocyanins, within the callus. It was found that sucrose can induce more anthocyanins, and its related metabolites and genes also increase as the sucrose and MS concentrations increase. Under the conditions of red-blue light and a temperature of 15 °C, it can further induce the production of more anthocyanins and secondary metabolites and can also upregulate the synthesis of anthocyanin-related genes. As such, this investigation serves to elucidate the factors that contribute to anthocyanin accumulation in red pears, thereby providing a theoretical foundation for understanding the mechanisms underlying color change.

“…Notably, IDM1 is outgroup to a clade that contains multiple Arabidopsis MYBs that belong to two subclades. One subclade contained MYBs that control trichome and root hair development (MYB0 (GLABRA 1), MYB23, and MYB66 (WEREWOLF)) 30,37,38 , whereas the other subclade is involved in the regulation of anthocyanin biosynthesis (MYB113/114, MYB75, and MYB90) 39,40 . IDM2 is outgroup to a clade that contains two less well-characterized Arabidopsis MYBs, MYB6 and MYB8 41 .…”

In plants, the biosynthetic pathways of some specialized metabolites are partitioned into specialized or rare cell types, as exemplified by the monoterpenoid indole alkaloid (MIA) pathway of Catharanthus roseus (Madagascar Periwinkle), the source of the anti-cancer compounds vinblastine and vincristine. In the leaf, the C. roseus MIA biosynthetic pathway is partitioned into three cell types with the final known steps of the pathway expressed in the rare cell type termed idioblast. How cell-type specificity of MIA biosynthesis is achieved is poorly understood. Here, we generated single-cell multi-omics data from C. roseus leaves. Integrating gene expression and chromatin accessibility profiles across single cells, as well as transcription factor (TF) binding site profiles, we constructed a cell-type-aware gene regulatory network for MIA biosynthesis. We showcased cell-type-specific transcription factors as well as cell-type-specific cis-regulatory elements. Using motif enrichment analysis, co-expression across cell types, and functional validation approaches, we discovered a novel idioblast specific TF (Idioblast MYB1, CrIDM1) that activates expression of late stage vinca alkaloid biosynthetic genes in the idioblast. These analyses not only led to the discovery of the first documented cell-type-specific TF that regulates the expression of two idioblast specific biosynthetic genes within an idioblast metabolic regulon, but also provides insights into cell-type-specific metabolic regulation.

“…We found four genes involved in anthocyanin metabolism expressed differentially, which were annotated as ANS , ANR , CHI , and F3′H . ANS, one of the key enzymes downstream of plant anthocyanin pathway, can catalyze the reaction of leucocyanidins to anthocyanins (Li et al, 2016; Turnbull et al, 2003). ANR is a crucial enzyme for the synthesis of proanthocyanidins with strong antioxidant effects (Yang et al, 2008).…”

Sodium nitroprusside (SNP), as a nitric oxide donor, is widely used in postharvest fruit physiology and metabolism. Our previous study has indicated that SNP plays a crucial role in postharvest browning control of rambutan, but the molecular mechanism underlying this process is still unclear. In this research, we investigated the gene expression and function of postharvest rambutan in response to SNP during browning. We found 7336 differentially expressed genes (DEGs), among which 2206 were upregulated and 5130 were downregulated. Gene Ontology (GO) enrichment as well as Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed, and the real-time quantitative PCR (qPCR) data were consistent with transcriptome data.The DEGs relevant to rambutan pericarp browning were mainly involved in anthocyanin biosynthesis, phenolic oxidation, reactive oxygen species (ROS) production, and energy supply. It was shown that SNP regulated the synthesis and degradation of anthocyanins, accumulation of phenols, level of ROS and energy metabolism to suppress the postharvest browning of rambutan. Also, one WRKY transcription factor involved in ROS metabolism was observed to be differentially regulated. These findings add to our insights into the molecular mechanisms of the SNP-induced browning delays of rambutan, which has implications for subsequent studies on molecular mechanisms of fruit browning.
