1. Activation of the heterotrimeric G protein α-subunit GPA1 suppresses the ftsh-mediated inhibition of chloroplast development in Arabidopsis

Subject:
Arabidopsis; gene expression; knockout mutants; leaves; microarray technology; proteins; signal transduction; thylakoids
Abstract:
... Heterotrimeric G protein knock-out mutants have no phenotypic defect in chloroplast development, and the connection between the G protein signaling pathway and chloroplast development has only been inferred from pharmaceutical evidence. Thus, whether G protein signaling plays a role in chloroplast development remains an open question. Here, we present genetic evidence, using the leaf-variegated mu ...

Subject:
Arabidopsis; N-acetylglucosamine; chimerism; cytokinins; gibberellins; glucocorticoid receptors; mutants; mutation
Abstract:
... Specific plant developmental processes are modulated by cross-talk between gibberellin (GA)- and cytokinin-response pathways. Coordination of the two pathways involves the O-linked N-acetylglucosamine transferase SPINDLY (SPY) that suppresses GA signaling and promotes cytokinin responses in Arabidopsis. Although SPY is a nucleocytoplasmic protein, its site of action and targets are unknown. Severa ...

Arabidopsis; Gloeobacter violaceus; Synechocystis; biosynthesis; chlorophyll; etioplasts; genes; heterologous gene expression; mutants; mutation; symbiosis
Abstract:
... In angiosperms, chlorophyll biosynthesis is light dependent. A key factor in this process is protochlorophyllide oxidoreductase (POR), which requires light to catalyze the reduction of protochlorophyllide to chlorophyllide. It is believed that this protein originated from an ancient cyanobacterial enzyme that was introduced into proto-plant cells during the primary symbiosis. Here we report that P ...
