Genome-wide identification, expression analysis, and response to abiotic stress of the phosphate transporter gene family in cucumber (Cucumis sativus L.).

ABSTRACT:

Background

Phosphorus (P) is an essential nutrient for plant growth and development, which plays a pivotal role in energy metabolism, signal transduction, and stress responses. However, approximately one-third of the world's arable soils have insufficient available phosphorus, severely limiting crop productivity. While their genetic characteristics have been extensively studied in various plant species, the specific roles of phosphate transporter (PHT) in cucumber remain largely unexplored.

Results

In this study, 17 CsPHT genes were systematically identified in the cucumber genome and classified into four subfamilies: CsPHT1, CsPHT2, CsPHT3, and CsPHO1. Analyses of physicochemical properties and structural features revealed distinct divergence among subfamilies in terms of p
