Energy balance, organellar redox status, and acclimation to environmental stress (2006, background): “Results with the Arabidopsis mutant genomes uncoupled 5 (gun5) indicate that perturbations of tetrapyrole biosynthesis generate at least two plastid-nuclear signalling pathways, one of which involves the H-subunit of Mg-chelatase, an enzyme involved in Chl biosynthesis (Mochizuki et al. 2001).”
Response of plants to water stress (2014, background): “AHK1, an Arabidopsis histidine kinase (HK) localized to the plasma membrane mediates osmotic-stress signaling in prokaryotes and has been shown to function as an osmosensor.”
GLK Transcription Factors Coordinate Expression of the Photosynthetic Apparatus in Arabidopsis[W][OA] (2009, methodology): “DP inhibits the conversion of ProtoIX to heme and also the conversion of Mg-ProtoIX to Pchlide, thus leading to the accumulation of Mg-ProtoIX and Mg-ProtoIX ME (Mochizuki et al., 2001; see also Figure 4).”
Sensing and responding to excess light. (2009, background): “The gun5 mutation was localized in the CHLH gene, which codes for the Mg-chelatase H subunit (105), and GUN4 is a porphyrinbinding protein that stimulates the activity of Mg-chelatase at low Mg2+ levels (26).”
