ESR1 Promotes Shoot Regeneration in Vitro.

(A) Shoot regeneration of wild-type, esr1-1, esr1-2, ESR1-SRDX, and ESR1-GFP root explants in vitro. Root explants were cultured on CIM for 4 d and transferred to SIM. Representative images of root explants cultured on SIM for 18 d are shown. Bars = 5 mm.

(B) Quantitative analysis of shoot regeneration phenotypes. Regeneration phenotypes are scored as the number of regenerating shoots per explant. Data are mean ± se (n ≥ 30 per genotype). Statistical significance was determined by a Student’s t test (***P < 0.001).
