Genome-wide identification and salt stress response analysis of the WD40 protein family in Populus yunnanensis.

ABSTRACT:

Background

The WD40 proteins constitute a large regulatory family involved in a wide range of biological processes and stress responses. Advances in sequencing technologies have facilitated the identification of numerous WD40 proteins with diverse functions in many plant species. However, research on tree species remains limited. Populus yunnanensis is an economically and ecologically important tree species that faces salt stress in certain habitats. Therefore, studying WD40 proteins in P. yunnanensis is of particular significance for understanding its salt tolerance mechanisms.

Results

A variable number of WD40 proteins were identified across six poplar species, generally correlating with their genome sizes. In P. yunnanensis, 258 PyWD40s were identified, exhibiting conside
