Phenotypic characterization of the dwfcp mutant. Phenotype comparison between WT (left) and dwfcp (right) seedlings at the stage of 7 true leavess. (A) Top view and (B) side view. (C) Comparison of plant height, stem diameter, root length, root biomass, and leaf biomass between WT and dwfcp at 7 true leaves seedling stage. (D) Chlorophyll content in WT and dwfcp leaves. (E) Growth rate of WT and dwfcp leaf petiole over time. (F) Growth rate of WT and dwfcp leaf blade over time. (G) Leaf development in WT (left) and mutant (right) plants. (H) Root growth and development during the establishment of WT and dwfcp seedlings (at 50 and 72 HAG). (I) Statistical comparison of parent root (PR) and LR length, number of LR, and LR branching density between WT and dwfcp at 50 and 72 HAG. (J) Width of the PR in three different zones (basal, middle, and apical) during the establishment of WT and mutant seedlings at 50 and 72 HAG. The LR branching density (cm⁻¹) was calculated as the number of emerged LR per unit length of the root branching zone (in centimeters). The root branching zone includes the zone of the parent root that extends from the most rootward emerged LR to the shoot base. Error bars represent SE. Different letters indicate significant differences (P ≤ 0.05).
