Schematic overview illustrating the library workflow, from design to screening. All coding genes were divided into phylogenetic trees, and trees were classified by function. sgRNAs were designed to target multiple genes located in close proximity to one another phylogenetically (indicated by colors). Each sgRNA was cloned into the Cas9 vector, creating a plasmid library. Transformed lines were screened with multi-targeted, large-scale, forward genetics for specific traits of interest, revealing hidden phenotypes. *Whole genome indicates all coding genes excluding transporters, transcription factors, and enzymes.

Double knockdown of ABCG17 and ABCG18 leads to changes in ABA response in the valves. A, pRAB18:GFP signal in mir17,g18 and Control siliques at 4 DAP. mir17,g18 is mir17 (amiRNA-ABCG17) transformed into the background of abcg18-1 T-DNA insertion line. Shown are two independent transformation lines (#1 and #5). Green is GFP fluorescent signal, and red is chlorophyll. Scale bar = 50 m. B, Average (±SD) GFP intensities in indicated lines. n ≥ 4; *, P value < 0.05, **, P value < 0.01, Student’s t test

Fig. 1. Hormones mediate root responses to water availability. (A) Under homogeneous water distribution in soil, lateral roots (LRs) develop symmetrically, resulting in a uniform root system. (B) Root tips show hydrotropism and bend towards areas with high water potential. ABA drives asymmetric expansion of cortical cells on the convex side of roots facing low water potential by the action of SnRK2.2. Both ABA and BR promote hydrotropism via the activity of the proton pump AHA2. Cytokinin (in red) exhibits asymmetric distribution at the root tip to regulate hydrotropism. (C) Growing root tips pause branching in air gaps (xerobranching). Lack of moisture triggers ABA release from the stele (st) to the outer root tissues, blocking the radial inward symplastic movement of auxin to pause root branching. ABA-mediated repression is relieved in the presence of water. ep, epidermis; co, cortex; en, endodermis.
