Sugar-dependent phenotype of retromer and sdp1 mutants. (A and B) WT, retromer (snx triple, vps29, vps35a vps35c), sdp1.4, and sdp1.5 mutant seedlings grown on MS medium with (A) or without (B) 1% (wt/vol) sucrose for 8 DAG. (Scale bar: 5 mm.) (C) Percentage of primary root length reduction induced by sugar deprivation. Values are mean ± SEM. Three independent experiments were performed, and a total of at least 42 seedlings were analyzed.
