Description
Yang and five co-authors asked why a pear variety sheds its calyx so readily in twenty twenty-four. The calyx is the leafy cap at the fruit's end; when it falls or persists it changes fruit quality. A mutant of the Korla fragrant pear, called Xinnonglinxiang, drops its calyx at a high rate.
The team sampled the shedding zone at three April stages in both varieties. Physiology, cell microscopy, and gene activity profiling were combined. Wall-digesting enzyme genes and plant hormone signaling genes differed most between varieties, especially mid-shedding. Network analysis found two gene modules tied to the hormone ethylene and twenty core genes, with three likely hubs. The results nominate candidate genes for breeding pears with a controlled calyx, the authors say.
