Gene Details:

• MSU gene ID: LOC_Os01g63220
• RAPdb gene ID: Os01g0851000
• Gene Symbol: WLP2 OsFLN1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Expression levels of PEP-encoded genes, chloroplast development genes and photosynthesis-related genes were compromised in WLP2 mutants, indicating that WLP2 is essential for normal chloroplast biogenesis.
• Our results strongly indicate that WLP2 protects chloroplast development from heat stress via a TRX-FLN regulatory module in rice.
• Map-based cloning suggested that WLP2 encodes a putative pfkB-type carbohydrate kinase family protein, which is homologous to fructokinase-like 1 (AtFLN1) in Arabidopsis.
• Moreover, WLP2 and its paralog OsFLN2 can physically interact with thioredoxin OsTRXz to form a TRX-FLN regulatory module, which not only regulates transcription of the PEP-encoded genes but also maintains the redox balance in chloroplasts under heat stress.
• Moreover, OsFLN1 localizes to the chloroplast.
• Yeast two-hybrid, pull-down and bimolecular fluorescence complementation experiments revealed that OsFLN1 and HSA1/OsFLN2 interact with THIOREDOXINZ (OsTRXz) to regulate chloroplast development.
• These results show that OsFLN1 and HSA1/OsFLN2 contribute to chloroplast biogenesis and plant growth.
