TL;DR: It is shown that microRNA (miR) miR397a regulates fruit cell lignification by inhibiting laccase (LAC) genes that encode key lignin biosynthesis enzymes.

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.

TL;DR: It is shown that PbrMYB169, an R2R3 MYB transcription factor, of Pyrus bretschneideri positively regulates lignification of stone cells in pear fruit and advances the understanding of the regulation of lignin biosynthesis.

TL;DR: The transcriptomes of five pear cultivars were sequenced at seven key fruit developmental stages, from fruit setting to maturation and fruit senescence after harvesting, and co-expression analysis revealed that several ethylene synthesis genes and polyphenoloxidase-related genes interacted with each other directly, and an indirect relationship was reflected between ethylenehesis genes and ethylene response genes.

TL;DR: This study is the first to reveal protein and associated mRNA variations in pear during fruit development and quality conformation, and identify key genes and proteins helpful for future functional genomics studies, and provides gene resources for improvement of pear quality.
