几丁质酶是一类病程相关蛋白，负责催化几丁质水解为N-乙酰-D-葡萄糖胺。因此，几丁质酶被认为是抵抗含有几丁质的病原体的保护者。在这里，我们研究了芜菁几丁质酶家族基因在根肿病中的作用。共鉴定出33个几丁质酶基因，并根据其保守结构域将其分为5类。它们在B的8条染色体上分布不均匀。其中31个含有少量内含子（
Chitinases, a category of pathogenesis-related proteins, are responsible for catalyzing the hydrolysis of chitin into the N-acetyl-D-glucosamine. Therefore, chitinases are believed to function as a guardian against chitin containing pathogens. Here, we examined the role of the Brassica rapa chitinase family genes in clubroot disease. A total of 33 chitinase genes were identified and grouped into five classes based on their conserved domain. They were distributed unevenly across eight chromosomes in B. rapa, and 31 of them contained few introns (
