Despite its biological importance, the mechanism of formation of cutin, the polymeric matrix of plant cuticles, has not yet been fully clarified. Here, for the first time, we show the participation in the process of lipid vesicles formed by the self-assembly of endogenous polyhydroxy fatty acids. The accumulation and fusion of these vesicles (cutinsomes) at the outer part of epidermal cell wall is proposed as the mechanism for early cuticle formation.
尽管角质（植物角质层的聚合物基质）的形成机制具有重要生物学意义，但尚未完全阐明。在此，我们首次展示了内源性多羟基脂肪酸自组装形成的脂质囊泡参与这一过程。这些囊泡（角质体）在表皮细胞壁外部的积累和融合被认为是早期角质层形成的机制。
