Extracellular freezing results in cellular dehydration caused by water efflux, which is likely regulated by aquaporins (AQPs). In a seasonal cold acclimation (CA) study of Rhododendron catawbiense, two AQP cDNAs, RcPIP2;1 and RcPIP2;2, were down-regulated as the leaf freezing tolerance (FT) increased from -7 to approximately -50 degrees C. We hypothesized this down-regulation to be an adaptive component of CA process allowing cells to resist freeze-induced dehydration. Here, we characterize… CONTINUE READING
