Glycerol-3-phosphate is a critical mobile inducer of systemic immunity in plants

Abstract: Glycerol-3-phosphate (G3P) is an important metabolite that contributes to the growth and disease-related physiologies of prokaryotes, plants, animals and humans alike. Here we show that G3P serves as the inducer of an important form of broad-spectrum immunity in plants, termed systemic acquired resistance (SAR). SAR is induced upon primary infection and protects distal tissues from secondary infections. Genetic mutants defective in G3P biosynthesis cannot induce SAR but can be rescued when G3P is supplied exog… Show more

“…13). A paralogous region (Block B) on chromosome 02 in G. soja and G. max contained three genes missing in Block A that were related to biotic and abiotic stress tolerance or plant development (Glyma02g38290, homolog of ZRZ/ZF14 or BCD1; Glyma02g38300, homolog of SUT4 and Glyma02g38310, homolog of GLY1) 13,14 (Fig. 1c).…”

“…Only a handful of factors specifically affect SAR without affecting local disease resistance [9][10][11][12][13] . These SAR-specific components are candidates for generating/mobilizing and/or being receptors for mobile signals.…”

“…These SAR-specific components are candidates for generating/mobilizing and/or being receptors for mobile signals. On the other hand, many natural priming signals have been proposed, including azelaic acid (AZA) and its precursor/derivatives, methyl salicylate, jasmonic acid, dehydroabietinal, pipecolic acid and a glycerol-3-phosphate-dependent metabolite 10,12,[14][15][16][17][18][19] . The existence of more than one signal capable of establishing a primed state suggests that plants may use a consortium of molecules to reach a certain 'priming threshold'.…”

“…Other studies have also come across evidence that glucosinolates might have regulatory properties within Arabidopsis and other plants [47,65,66]. Further, the rapid explosion of new regulatory metabolites for diverse processes within plants suggests that we should consider the likely potential that any chemical introduced into a plant may be sensed and cause regulatory changes within the plant itself [67][68][69]70 ]. Thus, part of any manipulation of the genetic background may have to involve removing the plants perception of the introduced compound or its precursors.…”
