TL;DR: In this study, a candidate R2R3 MYB TF, PyMYB114, was identified by linkage to the quantitative trait loci for red skin color on linkage group 5 in a population of Chinese pear, and this interaction network provides insight into the coloration of fruits and the interaction of different TFs to regulate anthocyanin biosynthesis.

TL;DR: The expression patterns of genes encoding enzymes indicated that ANS and UFGT were decisive genes for anthocyanin biosynthesis for red-skinned pear, and their different expressions led to the coloration differences between occidental and oriental pears.

TL;DR: It is speculated that the regulation of PA biosynthesis might be a key factor for this red/green color mutant, and this study can serve as a valuable new resource laying a solid foundation for functional gene identification in the anthocyanin pathway of red-skinned pear and provide a good reference for relevant research on molecular mechanisms of color variation in other pear species.

TL;DR: It was found that, in response to light, PybZIPa promoted anthocyanin biosynthesis by regulating important transcription factors as well as structural genes (PyUFGT) via binding to G-boxes within promoters.

TL;DR: The results provide an important reference for studying the molecular mechanism of light response and coloration in red pear and lay the foundation for future studies on red pear coloration research.
