Identification and substrate prediction of new Fragaria x ananassa aquaporins and expression in different tissues and during strawberry fruit development.

ABSTRACT: The newly identified aquaporin coding sequences presented here pave the way for further insights into the plant-water relations in the commercial strawberry (Fragaria x ananassa). Aquaporins are water channel proteins that allow water to cross (intra)cellular membranes. In Fragaria x ananassa, few of them have been identified hitherto, hampering the exploration of the water transport regulation at cellular level. Here, we present new aquaporin coding sequences belonging to different subclasses: plasma membrane intrinsic proteins subtype 1 and subtype 2 (PIP1 and PIP2) and tonoplast intrinsic proteins (TIP). The classification is based on phylogenetic analysis and is confirmed by the presence of conserved residues. Substrate-specific signature sequences (SSSSs) and specificity
