In my personal experience, cucurbits don't transplant well in cooler weather. L18 produced 34 fruits per plant, and a total of 580 fruits, including 308 curved fruits and 272 straight fruits, were used in this study. Whiteflies, mites, and thrips are among the most troublesome of the sap-feeders, though aphids, mealybugs, or scale can be occasional pests. 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. But on others the cotyledons turn yellow and shrivel before the true leaves get big enough to grow. A curve angle of 020 at 0 DPA correlated to straight fruit, while an angle >20 was indicative of a curved shape (Supplementary Fig. Mapping quantitative traits loci and proteomics studies on bending of cucumber fruit. Some of them are doing well. Cotyledons were excised from cucumber seedlings grown for 10 d under a 14-h light/10-h dark photoperiod and then kept in the dark for the number of days indicated.

In addition, the auxin biosynthesis genes YUCCA1, TAA1/WEI8, and TAR2 are upregulated in the hook region, and the wei8, tar2, and yuc1/2/4/6 mutants of A. thaliana display improper apical hook formation15,16. Systematic and integrative analysis of large gene lists using David bioinformatics resources. CsYUC11 is expressed in the male flowers of A. thaliana, and its overexpression promotes auxin accumulation and elongation of the pedicel and stamen45. The bugs and diseases are more often a symptom than the true source of problems. Auxin levels were markedly higher on the convex side than on the concave side of the curved fruits, peaking at 4 DPA and gradually declining thereafter. Should I start seeds early indoors in my zone? 4c). 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. of 13-13-13 fertilizer, then side dressed with 6 additional ounces (177.5 mL.) Following the application of AVG (0.1M) to the concave side of the ovary during the preanthesis stage, we observed that the fruit exhibited a relatively straight phenotype at 4 DPA (Supplementary Fig. 72, 316320 (1988). cucumber cotyledon curling Stormy, thanks for your comments.
