Remember to always use a safe pesticide. Fruits were sampled from L18 to analyze the expression of CsYUC10b. Planta 246, 641658 (2017). Cotyledons Leaves first curling, getting white and plant wilting and dying. At first I had them in a sunny window and then gradually moved them outside most of the day. Try planting resistant varieties like Liberty Hybrid, Saladin and County Fair 83 that are available in the market. Only three seem to be thriving, and I guess it's too late to just isolate those. After that, apply a fungicide that does not contain any toxic chemicals(our pick: Bonide Copper Fungicide), Also, Ive added some practical home-made recipes that you can try for downy mildew and other fungal diseases-. Development 137, 607617 (2010). Cotyledons were inoculated using a paint sprayer (15 PSI) until the entire surface of the cotyledons are covered. The data are the means (SEs) of three independent experiments, with five replicates each (p<0.05). 2b). Sometimes cucumbers need pruning for better cucumber growth. Also need to apply good amount of good amount of Farm Yard manure or Vermicompost too. It is evident if the plant sort of withers at ground level then falls over. Soil is wet more than enough. So the seedlings in the egg carton are fighting a serious uphill battle right from the start. Hortic Res 7, 135 (2020). 6b).

To learn more, see our tips on writing great answers. To further support our conclusions, we examined the impact of the auxin biosynthesis inhibitor AVG). Che, G. & Zhang, X. L. Molecular basis of cucumber fruit domestication. Lets check and rectify the situation at your end. c Ovary growth in Col and OX plants. Five mm long, the striped cucumber beetle is pale yellow with a black head and 3 black stripes down its back. 150, 11111121 (2009). Anal.

Through exogenous auxin (NAA, NOA, and AVG) treatment and gene functional verification, we found that overexpression of CsYUC10b promotes the development of straight fruit in cucumber. I realize these are pretty general suggestions, but I hope they will help you going forward. Just as too much or not enough light can cause yellowing seedling plants, too much or too little water or fertilizer could also be the problem. Thanks!

In a previous study, we analyzed the transcriptomes of curved cucumber fruits retrieved from the expressed sequence tag database19 and identified a putative auxin synthesis gene, CsYUC10b (Csa3G190380), that was likely associated with fruit curvature. Incorrect Growing Conditions: Cucumbers need very specific cultural conditions when their fruits are developing or those fruits may become deformed.
