Comparative genomics of light harvesting chlorophyll a/b binding protein (LHC) family in green jujube (Ziziphus mauritiana) reveal the effect of domestication based on haplotype-resolved genome.

ABSTRACT:

Background

Green jujube (Ziziphus mauritiana) is an economically important fruit tree with exceptional nutritional and medicinal values, particularly in tropical undeveloped regions. Light-harvesting chlorophyll a/b-binding proteins (LHC) holds crucial positions in plant photosystem, which is essential for the climate adaptability of green jujube. Nevertheless, comprehensive genome-wide investigation of LHC family genes have never been full studied in genus Ziziphus.

Results

Herein, we identified respectively 72 and 72 putative LHC genes both in wild and cultivated green jujube based on the haplotype-resolved chromosome-level genomes. These genes were classified into four subfamilies (LHCa, LHCb, ELIP, and PsbS) according to phylogenetic relationships and conserved domains.
