Description
Farzana Sabir and colleagues gave cork oak its first detailed map of aquaporins, the channel proteins that move water through plant cells. Their paper appeared in Plant Cell Reports in 2026. Cork oak woodlands face deepening drought as the climate warms, yet the tree's water plumbing was largely unstudied. The team tested four aquaporins in yeast, located them in young stems, and tracked their gene activity under mild drought.
Three of the four channels carried water in the yeast tests, and the NIP members also passed glycerol and other small molecules, including boron and arsenic. One channel was oddly switched on by mercury, an effect traced to a single amino acid. In stems, the channels spread across many tissue layers. Under drought, leaf and stem genes for two families rose while root levels fell, a pattern that may limit water leaking back into dry soil.
