Fig. 1: Mutations of glycosyltransferase genes affect shoot meristem development.

a GT mutants used for shoot apical meristem (SAM) analysis. The left panel shows a schematic representation of the organization of the cell wall. The primary cell wall in the meristematic cells mainly consists of cellulose, hemicellulose, pectin, and cell wall proteins that are typically modified with carbohydrate side chains. Mutants of each gene were selected based on their mRNA expression patterns. b Analysis of SAM size in the GT mutants. The size of the SAMs is determined by measuring the average of the radii of three successive primordia to the SAM center, and the results are displayed as box and whisker plots with individual data points. The error bars represent the maximum and minimum values. Center line, median; box limits, 25th and 75th percentiles. The color of the boxes correlates with the function of each gene in cell wall synthesis, as shown in (a). ^*P < 0.05, ^**P < 0.01, ^***P < 0.001, ^****P < 0.0001 (Unpaired two-tailed Student’s t-test, compared to Col-0). ns not significant. The exact P values are provided in the Source Data file.
