Dijon domains 2012 Group 1 Remorin, a plant phosphorylated protein located in membrane rafts, involved in virus propagation. Germain V., Perraki A., Bayer E., Mecchia M., binaghi M., German S., Zelada A., Mongrand S. The Remorin (REM) proteins are plant-specific oligomeric porteins that have been reported to localize to the plasma membrane despite their overall hydrophilic nature. There is evidence that the REM protein phosphorylation is potentially implicated in the early signalling and defense. Benshop et al. detected the AtREM1.3 (group 1b of REM protein family) to be phosphorylated in response to treatment with the general elicitor flg22, while the Widjaja et al. suggested that the phosphoryaltion of AtREM1.2 is potentially implicated in early signalling upon infection with Psudomonas syrinage. The precise exact function of the group 1 REM protein phosphorylation remains unknown. IN a previous work, we showed that Potato virus X (PVX) movement is inversely correlated to potato REM1.3 accumulation and tha St REM1.3 can interact physically with the movement protein TRIPLE GENE BLOCK PROTEIN 1( TGBp1) from PVX. In this work, we studied the phosphorylation of REN on the presence of virus. The physiological consequences of TGBp1/REM1.3 interaction and REM phosphorylation in terms of virus spreading, postarnscriptional gene silencing, plasmodesmata gating, kinase activation were also investigated.
