| Title | <i>Curling Leaf 1</i>, Encoding a MYB-Domain Protein, Regulates Leaf Morphology and Affects Plant Yield in Rice. | |
|
Abstract: The leaf is the main site of photosynthesis and is an important component in shaping the ideal rice plant architecture. Research on leaf morphology and development will lay the foundation for high-yield rice breeding. In this study, we isolated and identified a novel curling leaf mutant, designated <i>curling leaf 1</i> (<i>CL1</i>). The <i>CL1</i> mutant exhibited an inward curling phenotype because of the defective development of sclerenchymatous cells on the abaxial side. Meanwhile, the <i>CL1</i> mutant showed significant reductions in grain yield and thousand-grain weight due to abnormal leaf development. Through map-based cloning, we identified the <i>CL1</i> gene, which encodes a MYB transcription factor that is highly expressed in leaves. Subcellular localization studies confirmed its typical nuclear localization. Transcriptome analysis revealed a significant differential expression of the genes involved in photosynthesis, leaf morphology, yield formation, and hormone metabolism in the <i>CL1</i> mutant. Yeast two-hybrid assays demonstrated that CL1 interacts with alpha-tubulin protein SRS5 and AP2/ERF protein MFS. These findings provide theoretical foundations for further elucidating the mechanisms of <i>CL1</i> in regulating leaf morphology and offer genetic resources for practical applications in high-yield rice breeding. |
