Glucosyltransferases catalyze the transfer of glucose molecules from an active donor to acceptor molecules and are involved in many plant processes. SIP68, a tobacco glucosyltransferase protein, is a SABP2-interacting protein. It was identified in a yeast two-hybrid screen using SABP2 as bait and tobacco proteins as prey. SABP2, converts methyl salicylate to salicylic acid (SA) as a part of the signal transduction pathways in SA-mediated defense signaling. Subcellular localization is a crucial aspect of protein functional analysis to assess its biological function. The recombinant SIP68 tagged with eGFP was expressed transiently in Nicotiana benthamiana and observed under confocal microscopy. Fluorescent signals were observed in the epidermal cells. Subcellular fractionation of the tobacco leaves transiently expressing SIP68-+eGFP confirmed that SIP68 is localized in the cytosol. To study the role of SIP68 in plant stress signaling, transgenic lines with altered SIP68 expression were generated using RNAi and CRISPR Cas9 and analyzed.
