zll-1 stem cell defects are enhanced by increased ARF2 levels. a pCLV3:GFP-er expression is decreased in zll-1 pARF2:mARF2 bent-cotyledon and mature embryos compared to zll-1. b The severity of shoot meristem defects is enhanced in 14-day-old seedling of zll-1 pARF2:mARF2 compared to zll-1. Genotypes and embryo stages are indicated. The Chi-square test was used to calculate p-values. ***p < 0.001; n number of analyzed embryos. Shoot meristem defects: empty apex differentiated stem cell, no organ formation; pin single filamentous structure; 1 L one central leaf; 2 L termination into two leaves; wt wild-type-like
