Os01g0678600

The rice Os01g0678600 was reported as ASL1 in 2013 by researchers from China.

Annotated Information

Gene Symbol

• Os01g0678600 <=> ASL1,OsASL1

Function

• Plastid ribosomal proteins (PRPs) are essential for ribosome biogenesis, plastid protein biosynthesis, chloroplast differentiation, and early chloroplast development. * In their is study, the researchers identifies the first rice PRP mutant, asl1 (albino seedling lethality1), which exhibits an albino lethal phenotype at the seedling

stage.

• ASL1 is essential for chloroplast development in rice.
• ASL1 is involved in the establishment of the transcription/translation apparatus and plastid-to-nucleus signaling.
• ASL1 plays an important role in rice seedlings, especially at early stages.

Expression

• The researchers used RT-PCR to examine the expression of ASL1 in WT plants (Figure 5A). The researchers detected a significantly high level of expression in young leaves, culms, and flag leaves but weak expression in roots and young panicles. The ASL1 transcript was substantially reduced in asl1 mutants, indicating that the mutation in ASL1 causes a decreased transcript level.
• Light plays a major role in regulating ASL1 expression.

Subcellular localization

• The ASL1 protein was predicted to localize to chloroplasts by ChloroP and TargetP.
• Subcellular localization analysis of ASL1ASL1 protein is localized to the chloroplast.
