Abstract A pathogenic strain of Fusarium culmorum caused flax disease whose first visible symptom was pigmentation and possible necrosis of the root tip. To better understand the process of infection we tried to determine the role of cell wall polymers in flax treated with F. culmorum. F. culmorum infection caused cell wall rearrangement which was associated with changes in the cell wall structure without changes in the amount of polymers. Moreover, pathogenic fungi strongly induced chitinase, β-1,3-glucanase, cellulase2, α-galactosidase and lignin-related genes, while mRNA levels of the majority of genes involved in metabolism of cell wall polysaccharide polymers decreased in time.

感染镰刀菌致病菌株的亚麻中细胞壁聚合物的重排

摘要 一株致病性镰刀菌引起亚麻病，其最初的明显症状是色素沉着和可能的根尖坏死。为了更好地了解感染过程，我们试图确定细胞壁聚合物在用 F. culmorum 处理的亚麻中的作用。F. culmorum 感染引起细胞壁重排，这与细胞壁结构的变化有关，但聚合物的数量没有变化。此外，病原真菌强烈诱导几丁质酶、β-1,3-葡聚糖酶、纤维素酶2、α-半乳糖苷酶和木质素相关基因，而参与细胞壁多糖聚合物代谢的大多数基因的mRNA水平随时间下降。
