CCR4-Not complex is a multifunctional regulator that plays important roles in multiple cellular processes in eukaryotes. In the present study, the biological function of FonNot2, a core subunit of the CCR4-Not complex, was explored in Fusarium oxysporum f. sp. niveum (Fon), the causal agent of watermelon wilt disease. FonNot2 was expressed at higher levels in conidia and germinating conidia and...

This study was conducted to determine the influence of L-tryptophan (LTRP) applied to soil on the yield of two watermelon (Citrullus Lanatus L.) and one muskmelon (Cucumis melo L.) cultivars. Experiments were established in which L-TRP was applied to seedlings as a soil drench in the glasshouse ranging from 6 × 10 to 60 mg·kg soil; the seedlings were transplanted into the field 2 weeks later. T...
