Gene Details:

• MSU gene ID: LOC_Os07g09450
• RAPdb gene ID: Os07g0192300
• Gene Symbol: LM7 OsHSP40 NAL11
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Leaf Mutant 7 Encoding Heat Shock Protein OsHSP40 Regulates Leaf Size in Rice.
• Disruption of this gene in OsHSP40 mutants significantly reduced the leaf size compared with that of WT in rice.
• Microscopic examination showed that OsHSP40 modulated leaf size via regulating the veins formation and cell size/cell number.
• Therefore, the natural variation of OsHSP40 contributing to leaf size might be useful for rice breeding.
• Nucleotide diversity analysis indicated that a single nucleotide polymorphism (SNP) variation of C to T in the coding region of OsHSP40 may cause small leaves among rice accessions.
• Leaf Mutant 7 Encoding Heat Shock Protein OsHSP40 Regulates Leaf Size in Rice.
• NAL11 loss-of-function mutants present impaired chloroplast development and gibberellin (GA) defects.
• The DnaJ domain-containing heat-shock protein NAL11 determines plant architecture by mediating gibberellin homeostasis in rice (Oryza sativa).
• A promising rare allele of NAL11 (NAL11(-923del-1552) ) positively selected in Aus cultivars was identified; this allele exhibited increased expression and generated relatively few tillers, thick stems, and large panicles, components of the ideal plant architecture (IPA).
• Genetic analyses support the hypothesis that NAL11 acts downstream of IPA1 to regulate IPA by modulating GA homeostasis, and NAL11 may be an essential complement for IPA1.
• NAL11 is involved in regulating the cell cycle and cell proliferation.
• The DnaJ domain-containing heat-shock protein NAL11 determines plant architecture by mediating gibberellin homeostasis in rice (Oryza sativa).
• A promising rare allele of NAL11 (NAL11-923del-1552 ) positively selected in Aus cultivars was identified; this allele exhibited increased expression and generated relatively few tillers, thick stems, and large panicles, components of the ideal plant architecture (IPA).
