Background: Chlorophyll breakdown is the most obvious sign of leaf senescence. The chlorophyll catabolism pathway and the associated proteins/genes have been identified in considerable detail by genetic approaches combined with stay-green phenotyp...

Intercellular CO2 concentration of leaves (C-i) is a critical parameter in photosynthesis. Nevertheless, uncertainties in calculating C-i arise as stomata close. Here, by modifying the assimilation chamber of a commercial gas- exchange equipment t...

In the dicotyledonous plant Arabidopsis thaliana, the cotyledon chloroplast biogenesis factor AtCYO1 is crucial for the biogenesis of cotyledon chloroplasts. Arabidopsis mutants lacking AtCYO1 have pale cotyledons but develop normal mature leaves....

Allantoin, a stress-related purine metabolite, can activate JA responses via ABA in Arabidopsis, suggesting its possible involvement in the homeostasis of these phytohormones and their interplay in stress signaling.Allantoin is a metabolic interme...

Arabidopsis chloroplast biogenesis factor CYO2/At3g47650 is a cotyledon-specific chloroplast biogenesis factor CYO1 homolog. The cyo2 mutant showed pale-green leaves, and the maximum quantum yield of photosystem II in the mutant was much decreased...

I selected 120 genes that are co-expressed with ARC3 and FtsZ genes, chloroplast division factor, using a gene expression profile in Arabidopsis thaliana, and I got the T-DNA line of the each gene from a stock center. I screened the homo lines of ...
