Characterization of <i>Caleosin</i> Genes in <i>Carica papaya</i> and Insights into Lineage-Specific Family Evolution in Brassicales.

ABSTRACT: Caleosins (CLOs) or peroxygenases (PXGs), a class of structural proteins of lipid droplets (LDs), comprise a small family of multifunctional proteins widely involved in oil accumulation, organ development, and stress responses. Despite the proposal of two clades termed H and L in Arabidopsis thaliana, their evolution in the order Brassicales has not been well established. In this study, the first genome-wide analysis of the caleosin family was conducted in papaya (Carica papaya), a Caricaceae plant without any recent whole-genome duplication (WGD). A high number of five members representing both H and L clades were identified from the papaya genome. Further identification and comparison of 68 caleosin genes from 14 representative plant species revealed seven ort
