| Title | Identification and Expression Analysis of CCCH Zinc Finger Family Genes in <i>Oryza sativa</i>. | |
|
Abstract: CCCH zinc finger proteins (OsC3Hs) are a class of transcriptional regulators that play important roles in plant development and stress responses. Although their functional significance has been widely studied in model species, comprehensive genome-wide characterization of CCCH proteins in rice (<i>Oryza sativa</i>) remains limited. Using <i>Arabidopsis</i> CCCH proteins as references, we identified the CCCH gene family in rice and analyzed the physicochemical properties, subcellular localization, conserved structures, phylogeny, cis-regulatory elements, synteny analysis, spatiotemporal expression patterns, and expression patterns under drought, ABA, and MeJA treatments for the identified CCCH family members. The results showed that the rice CCCH family comprises 73 members, which are unevenly distributed across the 12 chromosomes. Phylogenetic analysis classified them into 11 subfamilies. Subcellular localization indicated that most members are localized in the nucleus. The upstream regions of CCCH promoters contain a large number of cis-regulatory elements related to plant hormones and biotic stress responses. Most genes respond to drought, abscisic acid (ABA), and methyl jasmonate (MeJA) treatments. <i>OsC3H36</i> was highly expressed under drought, ABA, and MeJA treatments. Haplotype analysis of this gene revealed two major allelic variants (H1 and H2), with H1 predominantly found in japonica rice and associated with increased grain width and 1000-grain weight. Functional validation using a chromosome segment substitution line (CSSL1) confirmed these findings. CCCH genes play important roles in rice growth, development, and stress responses. Additionally, we validated that OsC3H36 is associated with rice grain width and 1000-grain weight. |
