The rice Os02g0649300 was reported as OsSLI1 in 2014 [1] by researchers from China.
Contents
Annotated Information
Gene Symbol
- Os02g0649300 <=> OsSLI1
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.
Figure 3. Effects of OsEXPA3 downregulation on the root system architecture. (a) Primary root length of 1-wk-old seedlings. (b) Lateralroot density of 1-wk-old seedlings. Two independent transgenic lines (Line 1 and Line 3) were analyzed. The seeds were placed on half-strength Murashige and Skoog solid medium and grown for 7 d vertically in a growth chamber. Primary root length was determined using a ruler. All visible lateral roots that emerged from the primary root were counted. Values are the means of 20 biological replications ± standard error. One independent plant was considered as one biological replication.[1].
