Xylan-rich nanodomains at pit borders of xylem vessels determine a pitted wall pattern by anchoring cellulosic nanofibrils at the pit edges and are crucial to support vessel robustness, water transport and leaf transpiration. These nanocompartments are mostly produced by the de novo xylan synthase IRREGULAR XYLEM (IRX)10 and its homologues.

前所未有的多糖纳米结构维持血管壁图案和稳健性

木质部容器凹坑边界处富含木聚糖的纳米域通过在凹坑边缘锚定纤维素纳米纤丝来确定凹坑壁图案，并且对于支持容器稳健性、水分运输和叶片蒸腾至关重要。这些纳米隔室主要由从头木聚糖合酶 IRREGULAR XYLEM (IRX)10 及其同系物产生。
