Phosphoproteome of the parasitic weed Phelipanche ramosa during early germination triggered by synthetic strigolactone analog

ABSTRACT: Root parasitic plant of the Orobanchaceae family, branched broomrape (Phelipanche ramosa), is one of the most economically damaging agricultural weeds. As an obligate holoparasite lacking chlorophyll, it depends entirely on the host plant for nutrition. Its germination is a unique two-phase process: An initial conditioning period in which seeds acquire the ability to respond to host-derived germination stimulants—strigolactones—follows by active germination upon induction by these signals. We conducted a pioneering phosphoproteomic analysis of the branched broomrape to elucidate the role of strigolactones in regulating phosphorylation/dephosphorylation during seed germination. Thus, we mapped signaling pathways and protein kinases plausibly involved in the process. We highlighted several kinases putatively regulating the strigolactone analog-triggered germination in parasitic weeds. We added essential pieces to the knowledge puzzle, which will eventually resolve a costly issue in the farming of vital crops.
