Effect of day length on flowering time and developmental traits in NILs carrying different alleles of PvE1. (IMAGE)
Caption
Effect of day length on flowering time and developmental traits in NILs carrying different alleles of PvE1. Plants were grown under long-day (LD2022, 16 h light) and short-day (SD2022, 11 h light) conditions. (A) Close-up images of axillary meristems at ~30 days after emergence (DAE) used as a proxy for the timing of floral induction. NIL026-e1 and PHA0595 exhibit visible flower buds, whereas NIL026-E1 and PHA1037 retain vegetative meristems under LD, indicating delayed floral transition. Days to Flowering (DTF) for each genotype are included in the image. VM, Vegetative Meristem; IM, Inflorescence Meristem; BF, Flower Buds. (B–E) Phenotypic analysis of DTF (B), DTIP (C), NNF (D), and TPH (E). PHA1037, which did not flower, was assigned a DTF value of 200 days. Statistical significance for NIL026-E1 vs. NIL026-e1 was assessed using pairwise Student’s t-test; ***, **, and ns indicate significant differences between NILs at P < 0.001, P < 0.01, and no significant difference, respectively.
