Holding all the CARDs: Quinone-induced oxidation and phosphorylation of GRXC1 impacts root growth

Holding all the CARDs: quinone-induced oxidation and phosphorylation of GRXC1 impacts root growthGiven their sessile lifestyle, plants utilize a sophisticated set of perception mechanisms for adjusting to an ever-changing environment.Perceived triggers can be abiotic, such as light, drought and salinity, or biotic -from the plant itself or from other interacting species.Regarding other species, specific signals can be mediated by biologically active compounds, called allelochemicals, which are produced by plants to influence plant-plant, plant-insect and plantmicrobe interactions (allelopathy) (Bais et al., 2003).Allelochemicals are a subset of secondary metabolites and include quinones, which are widely synthesized redox-active molecules (Hillion
