Genbank accession number

• We demonstrated that TSV protects rice chloroplasts from cold stress by interacting with OsTrxZ
• wp2 and Ostrx z knockout lines show reduced editing efficiencies in many plastidial-encoded genes especially under high temperature conditions

• OsTRXZ~WP2, TCD5~CSV1~TSV, TSV, a putative plastidic oxidoreductase, protects rice chloroplasts from cold stress during development by interacting with plastidic thioredoxin Z, Strikingly, TSV interacted with OsTrxZ (a subunit of PEP in chloroplasts) and enhanced OsTrxZ stability under low temperatures.
• OsTRXZ~WP2, WLP2~OsFLN1, White Leaf and Panicle 2, encoding a PEP-associated protein, is required for chloroplast biogenesis under heat stress in rice., 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
• OsTRXZ~WP2, WLP2~OsFLN1, FRUCTOKINASE-LIKE PROTEIN 1 interacts with TRXz to regulate chloroplast development in rice., Yeast two-hybrid, pull-down and bimolecular fluorescence complementation experiments revealed that OsFLN1 and HSA1/OsFLN2 interact with THIOREDOXINZ (OsTRXz) to regulate chloroplast development
• OsTRXZ~WP2, WLP2~OsFLN1, FRUCTOKINASE-LIKE PROTEIN 1 interacts with TRXz to regulate chloroplast development in rice., Quantitative reverse transcription polymerase chain reaction and immunoblot analysis revealed that the transcription and translation of PEP-dependent genes were strongly inhibited in fln1 and trxz mutants, indicating that loss of OsFLN1, HSA1/OsFLN2, or OsTRXz function perturbs the stability of the transcriptionally active chromosome complex and PEP activity
