Expression differences of anthocyanin biosynthesis genes reveal regulation patterns for red pear coloration
TLDR
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.Abstract:
Key message

An R2R3 MYB transcription factor associated with regulation of the anthocyanin biosynthetic pathway in Rosaceae
Kui Lin-Wang,Karen Bolitho,Karryn Grafton,A.J. Kortstee,Sakuntala Karunairetnam,Tony K. McGhie,Richard V. Espley,Roger P. Hellens,Andrew C. Allan +8 more
TL;DR: In this paper, the authors used gene specific primers to show that the three activators of apple anthocyanin (myb10/myb1/myBA) are likely alleles of each other.

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.

Genome-Wide Identification, Evolution and Functional Divergence of MYB Transcription Factors in Chinese White Pear (Pyrus bretschneideri)
TL;DR: The phylogenetic, evolution and expression analyses of the MYB gene family in Chinese white pear establish a solid foundation for future comprehensive functional analysis of Pbr MYB genes.

Transcriptome profiling reveals differential gene expression in proanthocyanidin biosynthesis associated with red/green skin color mutant of pear (Pyrus communis L.)
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.

Transcriptome Analysis Reveals Candidate Genes Related to Color Fading of 'Red Bartlett' ( Pyrus communis L.).
TL;DR: This study demonstrated that color fading of ‘Red Bartlett’ was closely linked to reduced anthocyanin biosynthesis, increased anthocianin degradation and suppression of anthoclynin transport, and provided novel evidence for the involvement of light signals in the color fades of red-skinned pears.
