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 |

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 |
