- Key message
- The defective OscpSRP54a (LOC_Os11g05552) was responsible for the pale green leaf phenotype of the viable pale green leaf 14 (pgl14) mutant
- Conclusion: Our study demonstrated that both OscpSRP54a and OscpSRP54b were essential for normal chloroplast development by interacting with OscpSRP43 in rice
- OscpSRP54a and OscpSRP54b might play distinct roles in transporting different chloroplast proteins into thylakoids through cpSRP-mediated pathway
- Both OscpSRP54a and OscpSRP54b were constitutively expressed mainly in shoots and leaves at the vegetative growth stage
- Here, we isolated and characterized a thermosensitive yellow-green leaf mutant named tsyl1 (thermosensitive yellow leaf 1) from an ethylmethylsulfone (EMS)-mutagenized pool of rice
- Furthermore, and chloroplast development-related genes was influenced in tsyl1 at different temperatures
- The expression of tsyl1 was induced by high temperature
- These results indicated that the TSYL1 gene plays a key role in chlorophyll biosynthesis and is affected by temperature at the transcriptional level
- At the mature stage of the tsyl1 mutant, the plant height, tiller number, number of spikelets per panicle and 1000 seed weight were decreased significantly compared to those of wild-type plants, but the seed setting rate and panicle length were not
- Connection
- OscpSRP43~PGL3, YGL138(t)~OscpSRP54a~TSYL1, Chloroplast SRP54s are Essential for Chloroplast Development in Rice, Both OscpSRP54a and OscpSRP54b were able to interact with OscpSRP43, respectively
- OscpSRP43~PGL3, YGL138(t)~OscpSRP54a~TSYL1, Chloroplast SRP54s are Essential for Chloroplast Development in Rice, In contrast, the transcript levels of OscpSRP54a, OscpSRP43 and OscpSRP54b were all significantly decreased in OscpSRP54b knockout lines
- OscpSRP43~PGL3, YGL138(t)~OscpSRP54a~TSYL1, Chloroplast SRP54s are Essential for Chloroplast Development in Rice, Conclusion: Our study demonstrated that both OscpSRP54a and OscpSRP54b were essential for normal chloroplast development by interacting with OscpSRP43 in rice
