Protein Variants

Protein Variants Comment Organism
agy1 a loss-of-function mutant of cpSecA, an albino or glassy yellow mutant, identified when screening a T-DNA insertion mutant collection. The mutant can grow normally on dim light with an exogenous carbon supply, but is subject to photo-oxidative stress in the light. Chloroplast biogenesis is clearly comprised in the mutant, and the transcription of both nucleus- and chloroplast-encoded photosynthetic proteins is repressed, whereas the transcription of mitochondrion-encoded respiratory complexes is induced Arabidopsis thaliana

General Information

General Information Comment Organism
physiological function AtcpSecA plays an essential role in chloroplast biogenesis, structure and function, the absence of which triggers a retrograde signalling (chloroplast-to-mitochondrion) possibly leads to reprogramming of chloroplast and mitochondrion gene expression to alleviate photooxidative stress in order to survive with an insufficient energy supply Arabidopsis thaliana
