YCF3 is essential for the assembly of the photosystem I (PSI) complex. In Chlamydomonas reinhardtii, it seems to act as a PSI specific chaperone facilitating the assembly of the complex by interacting with PsaA and PsaD.
RP- L24, PLASTID RIBOSOMAL PROTEIN L24, RPL24, SUPPRESSOR OF VARIEGATION 8, SVR8
Background:
RPL24/SVR8 is a plastid 50S ribosomal protein. It functions as a structural constituent of the ribosome and is involved in plastid translation. It localizes to the chloroplast stroma and chloroplast envelope.
pTAC12, HEMERA, HMR, PLASTID TRANSCRIPTIONALLY ACTIVE 12, TAC12
Background:
In chloroplasts, transcription of plastid genes is mediated by two types of RNA polymerase: plastid-encoded RNA polymerase (PEP) and nuclearencoded RNA polymerase (NEP). Transcription in plastids is also mediated by a number of nuclear-encoded factors in addition to PEP and NEP. In the insoluble RNA polymerase preparation samples, a total of 18 components named as pTACs (pTAC1 to pTAC18) were identified. pTAC12 (AT2G34640) is one of the components associated with PEP complex.
FTSH4 is an FtsH protease that is localized to the mitochondrion. Loss of function results in increased determinacy of the meristem that is exacerbated when plants are grown at higher temperatures.
