Description
Summary:The <i>PLATZ</i> gene family, known for its pivotal roles in regulating plant growth, development, and stress responses, is of great significance in rice biology and crop improvement efforts. In this study, we undertook a comprehensive identification and analysis of the <i>PLATZ</i> gene family across 10 <i>Oryza</i> genus species, including both cultivated and wild rice varieties. A total of 144 <i>PLATZ</i> genes were identified, demonstrating their widespread distribution. Phylogenetic analysis revealed six distinct groups among these genes, with high sequence similarity among members indicating a common evolutionary origin and potential functional conservation. Further analysis of conserved motifs, domains, and promoter regions provided insights into the transcriptional regulation and potential functions of <i>PLATZ</i> genes. Notably, expression profiling showed differential expression patterns of specific <i>PLATZ</i> genes, such as <i>OsPLATZ7</i>, <i>OsPLATZ9</i>, and <i>OsPLATZ11</i>, under various abiotic stress conditions and hormone treatments, highlighting their important roles in stress adaptation and hormone signaling. Additionally, the consistently high expression of <i>OsPLATZ9</i> across multiple tissues suggests its involvement in multiple developmental processes. Overall, this study provides a detailed characterization of the <i>PLATZ</i> gene family in rice, laying the foundation for future functional studies and potential applications in agricultural biotechnology.
