Gene Details:

• MSU gene ID: LOC_Os04g46580
• RAPdb gene ID: Os04g0551500
• Gene Symbol: OsSPL7
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Plants over-expressing OsSPL7 had a reduced tiller number, while OsSPL7 RNAi plants had an increased tiller number and a reduced height.
• Genetic analysis showed that OsSPL7 is a target of miR156f that regulates plant architecture.
• Heat stress transcription factor OsSPL7 plays a critical role in reactive oxygen species balance and stress responses in rice.
• OsSPL7 knockout (spl7ko) mutants showed LM and growth retardation.
• Transgenic rice lines strongly overexpressing OsSPL7 (SPL7OX-S) exhibited LM accompanied by accumulated H2O2, whereas moderate expressers of OsSPL7 (SPL7OX-M) did not, and neither of them exhibited severe growth defects.
• Collectively, our results suggest that OsSPL7 plays a critical role in plant growth and balancing ROS during biotic and abiotic stress.
• Transient expression of OsSPL7-GFP in rice protoplasts indicated that OsSPL7 localizes predominantly in the nucleus.
• Herein, we provide several lines of evidence elucidating the importance of OsSPL7 in maintaining reactive oxygen species (ROS) balance via the regulation of downstream gene expression.
• RNA sequencing analyses identified four major groups of differentially expressed genes associated with LM, pathogen resistance, LM-pathogen resistance, and potential direct targets of OsSPL7.
