## Contribution

The study is the first to analyze the KEA gene family in rice using bioinformatics methods.

## Key findings

- Eight KEA family genes were identified in rice with specific chromosomal localization.

- The findings provide a foundation for understanding the function of KEA genes in rice.

## Abstract

KEA (K+/H+ reverse transporter, K+ efflux antiporter) gene family belongs to the CPA2 reverse transporter superfamily gene, which plays an important role in regulating plant growth and development and stress resistance by maintaining intracellular PH balance and K+ concentration. The studies on the function of KEA gene in plants mainly focus on Arabidopsis thaliana, and the studies on the function of KEA gene family in rice have not been reported. In this study, the evolutionary tree analysis, chromosome localization, protein physicochemical properties and tissue expression of rice KEA gene family were analyzed by bioinformatics methods. Eight KEA family genes were identified in rice, some localized on specific chromosomes, with particular domains and different expression patterns. These results provided references for the research and analysis of the function of rice KEA gene family.
