31648387-4	2020	Recently, GUN1 was found to interact physically with factors involved in chloroplast protein homeostasis, and with enzymes of tetrapyrrole biosynthesis in adult leaves that function in various retrograde signalling pathways.	Tetrapyrroles	126-138	s uncoupled 1	Arabidopsis thaliana	10-14	
31732672-0	2019	The retrograde signaling protein GUN1 regulates tetrapyrrole biosynthesis.	Tetrapyrroles	48-60	s uncoupled 1	Arabidopsis thaliana	33-37	
31732672-6	2019	Here, we show that GUN1 directly binds to heme and other porphyrins, reduces flux through the tetrapyrrole biosynthesis pathway to limit heme and protochlorophyllide synthesis, and can increase the chelatase activity of FC1.	Tetrapyrroles	94-106	s uncoupled 1	Arabidopsis thaliana	19-23	
31732672-7	2019	These results raise the possibility that the signaling role of GUN1 may be manifested through changes in tetrapyrrole metabolism, supporting a role for tetrapyrroles as mediators of a single biogenic chloroplast-to-nucleus retrograde signaling pathway.	Tetrapyrroles	105-117	s uncoupled 1	Arabidopsis thaliana	63-67

Tetrapyrroles	152-165	s uncoupled 1	Arabidopsis thaliana	63-67	
26823545-4	2016	Genetic evidence suggests that the chloroplast protein GUN1 integrates signals derived from perturbations in plastid redox state, plastid gene expression, and tetrapyrrole biosynthesis (TPB) in Arabidopsis (Arabidopsis thaliana) seedlings, exerting biogenic control of chloroplast functions.	Tetrapyrroles	159-171	s uncoupled 1	Arabidopsis thaliana	55-59
