Cell wall–membrane anchors keep plant cells resilient during drought

When cells lose water, the plasma membrane pulls away from the cell wall except at attachment points first described more than a century ago as Hechtian strands. Yue Rui and colleagues identified the molecular basis of these attachments: cellulose synthase complexes establish them, while remorin proteins limit their number. Plants with more attachment points recover better from osmotic stress, revealing a tunable structural mechanism of drought resilience. The work was done with Peter Dahlberg and collaborators at Carnegie, Aarhus, Rutgers, Freiburg and UNC.
