Abstract
Seeds survive in a low-hydrated state and germinate upon water exposure. In a recent issue of Cell, Dorone et al. describe the prion-like protein FLOE1 and its role in inhibiting seeds' response to low water levels. Upon hydration, FLOE1 undergoes phase separation from the cytoplasm into gel-like droplets.
摘要
种子在低水合状态下存活，并在接触水时发芽。在最近一期的《细胞》杂志上，多罗内等人描述了朊病毒样蛋白 FLOE1 及其在抑制种子对低水平水分的反应中的作用。在水合作用下，FLOE1 从细胞质中相分离成凝胶状液滴。
