The cucumber mosaic virus can cause the leaves to roll upward and turn yellow with a wrinkled appearance. Infection of cucumber seedlings by cucumber mosaic virus (CMV) caused a significant reduction in the chlorophyll content of cotyledons corresponding with the appearance of chlorotic lesions. Zhou, X., Qin, Z. W. & Wang, X. G. Commercial evaluation of cucumber resources. Fruit seems to be growing but I dont think for long. Minerals from fertilizer can build up very quickly in seedlings small containers, effectively strangling the plants. 6c). Univ. d CsYUC10b levels on both sides of Col and OX fruits. They make tiny little holes in the plant that curl up the edges of the leaves. In this article, I have tried to include all the information about cucumber leaves curling up with their practical treatments. Cucumber cotyledons turn yellow and shrivel too soon, https://www.extension.umn.edu/garden/yard-garden/diseases/damping-off/, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI.

Fruit shape is a critical factor determining commercial production, germplasm accession classification, and consumer preference. As the ovaries of cucumber flowers are elongating, young fruits can easily deform when they catch on flower petals, vines, or leaves. Fruit development typically progresses from preanthesis ovary growth to ripening46. In Arabidopsis thaliana and maize (Zea mays), auxin biosynthesis involves a two-step pathway starting with the conversion of tryptophan to indole-3-pyruvate (IPA) by tryptophan aminotransferase (TAR2), a member of the aminotransferase Arabidopsis (TAA) family, followed by catalysis of IPA into the major endogenous auxin indole-3-acetic acid (IAA) by YUCCA flavin-containing monooxygenases10. To determine the role of auxin in the development of curved fruits, we measured auxin levels on both sides of curved and straight fruits from 2 to 8 DPA. 66, 34053416 (2015). Likewise, CmYUC6 and CmYUC11 are significantly upregulated in the seeds and fruit mesocarp of melon (Cucumis melo)43, and high YUCCA levels in strawberry seeds correlate with auxin biosynthesis and fruit development44.
