In ascomycete fungi, hyphal cells are separated by perforate septa, which allow cell-to-cell communication. To protect against extensive wound-induced damage, septal pores are sealed by peroxisome-derived Woronin bodies (WBs). The mechanism underpinning WB movement is unknown, but cytoplasmic bulk flow may "flush" WBs into the pore. However, some studies suggest a controlled and active mechanism of WB movement. Indeed, in the wheat pathogen Zymoseptoria tritici cellular ATP prevents WBs from pore sealing in unwounded cells. Thus, cells appear to exert active control over WB closure. Here, we summarize our current understanding of WB-based pore sealing in ascomycete fungi.

沃罗宁基于身体的间隔毛孔封闭。

在子囊真菌中，菌丝细胞被穿孔的隔片隔开，从而允许细胞间的通讯。为了防止伤口引起的广泛损害，隔室毛孔被过氧化物酶体的沃罗宁体（WBs）封闭。支撑WB运动的机制尚不清楚，但是细胞质大量流动可能会将WB“冲洗”到孔中。但是，一些研究表明WB运动的受控和主动机制。的确，在小麦病原体小麦枯萎菌中，细胞ATP可以阻止WBs在未受伤的细胞中进行孔封闭。因此，细胞似乎对WB闭合起主动控制作用。在这里，我们总结了目前对子囊真菌中基于WB的孔密封的理解。
