Fig. 4From: Cytokinin-microbiome interactions regulate developmental functionsBacilli isolated from high-CK genotypes affect development in seedlings. S. lycopersicum cv. M82 seedlings were treated with indicated bacteria (OD600 = 0.1), once a week for 2 weeks, starting from cotyledon emergence. Developmental parameters were measured in 10 day old M82 mock and bacterial isolate treated seedlings. A Seedling height (root crown to main shoot apical meristem) in centimeters. B Seedling weight. C Number of leaves produced starting from P1 (all initiated leaves were counted by dissecting the shoots). Boxplots depict minimum to maximum values, with box indicating inner quartile ranges and whiskers representing outer quartile ranges. Lines in box indicates median. Five independent experiments were conducted. Asterisks represent statistical significance from mock treatment in a one-way ANOVA with a Tukey post-hoc test (A, B), or a two-tailed t-test with Welch's correction (C). *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001, ns = non significant.
