{"project":"CucurLitBase-testset_BFT","denotations":[{"id":"T8","span":{"begin":219,"end":227},"obj":"BFT:3.3.1 salt stress tolerance"}],"text":"Watermelon is a strong economic value crop that is in the Cucurbitaceae family. During its growth and developmental process, the plants often suffer from biological and abiotic stress, such as drought, low temperature, salinity, wilt, and powdery mildew. In previous studies, chitinase was considered to belong to a class of PR proteins which play important roles in the interaction between plants, microorganisms, and stress and the regulation of plant growth and development in many species. However, their potential functions have not been studied in watermelon. In this study, 23 chitinase genes were identified in watermelon and designated ClChi genes. Moreover, their distribution on chromosomes, structure, evolutionary relationships, and patterns of expression in response to plant hormones and biological/abiotic stress were further analyzed. This study will help to dissect the important roles of ClChit genes involved in the growth and development of watermelon and its resistance to external stress factors."}
