Summary: Leaf morphology is an important trait for plant architecture and stress resistance. In this study, a rice mutant, ltr1, with rumpled leaves and decreased grain yield was identified. LTR1, a wax synthesis gene, was found to be constitutively expressed in various tissues, with higher expression in leaves and panicles. Overexpression of LTR1 increased grain yield and positively regulated salt stress by affecting water and ion homeostasis. These findings provide insights into the molecular mechanisms of leaf morphogenesis and stress response, and offer a potential strategy for stress-tolerance breeding.

Summary: A mutant rice flo22 showed delayed amyloplast development in endosperm cells, affecting mitochondrial morphology and function. Flo22, encoding a mitochondrion-localized P-type PPR protein, mutations led to defective trans-splicing of mitochondrial nad1 intron 1 and affected complex I assembly and activity. Additionally, FLO22 interacted with DYW3 and participated in mitochondrial RNA editing.

Summary: In this study, a leaf mutant with small leaf size was identified and its location on chromosome 7 was determined. The candidate gene OsHSP40 was found to be responsible for leaf size regulation in rice. The study also revealed that OsHSP40 affects leaf size by modulating vein formation and cell size/cell number.

Summary: Moderate leaf rolling is important for improving photosynthetic efficiency and grain yield in rice. This study identified a mutant with adaxially rolled leaves, which was caused by a mutation in OsDRB2 gene. The mutation affected the accumulation of miRNAs and the expression of related genes, leading to abnormal leaf development.

Summary: This study reveals that OsSAUR10 plays a role in cell elongation and contributes to plant growth in rice. The expression of OsSAUR10 is regulated in a tissue-specific, developmental, and hormone-dependent manner. Mutants of OsSAUR10 exhibit various developmental defects. Furthermore, OsSAUR10 is involved in regulating the expression of genes related to auxin biosynthesis and polar transport.

Summary: The mutant spl42 exhibits a reddish-brown spotted leaf phenotype, with significantly lower chlorophyll content and abnormal thylakoid morphology. Reactive oxygen species (ROS)-scavenging enzyme activities are elevated in the mutant. Genes related to chloroplast development and chlorophyll biosynthesis are down-regulated, while genes involved in leaf senescence, ROS production, and defense responses are upregulated in the spl42 mutant. Map-based cloning revealed that SPL42 encodes a porphobilinogen deaminase (PBGD), with significantly reduced enzyme activity due to a base substitution.

Summary: This study identifies a rice mutant, VPB1, which plays a role in regulating inflorescence architecture by affecting gene expression and interacting with other genes, especially OsBOPs. VPB1 is found to preferentially express in inflorescence and branch meristems, and disruption of its function leads to disturbed arrangement of primary branch meristems in rice. The findings highlight the importance of VPB1 in controlling rice inflorescence architecture.
