| Title | Identification and expression pattern analysis of the <i>OsCBL</i> gene family in rice. | |
|
Abstract: Calcium (Ca2+) signaling, which is mediated by calcineurin B-like proteins (CBLs), plays a pivotal role in the way that plants respond to abiotic stresses. However, the systematic bioinformatics and expression pattern analysis of <i>OsCBLs</i> remain largely unknown. In this study, we conducted a thorough genome-wide analysis of the <i>OsCBL</i> gene family in rice, identifying ten members spanning six chromosomes. Phylogenetic analysis classified these genes into three subfamilies, revealing evolutionary conservation with <i>Zea mays</i> and <i>Hordeum vulgare</i>, while also highlighting lineage-specific expansions. Structural characterization revealed that all OsCBL proteins contain three conserved EF-hand domains, though variations in protein stability, subcellular localization and motif composition were observed, particularly with regard to the chloroplast localization of OsCBL4/8/9/10. Promoter analysis revealed distinct <i>cis</i>-elements linked to responses to abscisic acid, drought and light, suggesting functional diversification among the different members. Expression profiling revealed that <i>OsCBL5</i> and <i>OsCBL9</i> were specifically induced by heat but repressed by cold. In contrast, <i>OsCBL3</i> responded to various stresses, including salt and temperature. Predictions of protein-protein interactions linked several OsCBLs to ion transporters. Notably, the functions of OsCBL1 and OsCBL9 may be exerted through the formation of a heterodimer. These findings provide critical insights into the functional divergence of <i>OsCBL</i> genes and lay the groundwork for future studies on calcium-mediated stress responses in rice. |
