The rice Os02g0649300 was reported as OsSLI1 in 2014 [1] by researchers from China.

Annotated Information

Gene Symbol

  • Os02g0649300 <=> OsSLI1
Figure 6. Nuclear localization of OsSLI1-GFP fusion protein.[1].

Function

  • OsSLI1 encodes member of the HD-Zip I subfamily
  • OsSLI1 may be a transcriptional activator regulating stress-responsive gene expression and panicle development in rice.
  • It was found that OsSLI1 expression was enhanced in an ABI5-Like1 (ABL1) deficiency mutant abl1 under both normal and stress conditions, suggesting that ABL1 probably negatively regulates OsSLI1 gene expression.

Expression

  • Quantitative RT-PCR result showed that in the seedlings, OsSLI1 expression was mainly in root.
  • The root tissue accumulates 7 times of OsSLI1 transcripts than in shoot tissue.
  • In panicles, the expression changes in different development stages, from relative low in 3 cm young panicles to a 33-fold increase in 8 cm panicles, and the 12 cm panicles still accumulate 8-fold OsSLI1 transcripts compared to 3 cm young panicles tissue.
  • Quantitative RT-PCR assay showed that OsSLI1 expression was highly induced by salt, PEG, H2O2 , high temperature, and ABA treatment but not by cold treatment.

Subcellular Localization

  • OsSLI1 is a nuclear-localized protein, in consistency with its potential function as a DNA binding transcription factor.
