Fig 1. Transcriptomic analysis of class 1 XTH genes during lateral root (LR) initiation.

Fig 1

(A) After gravitropic stimulation to induce the synchronized initiation of lateral root primordia (LRP) at the surface of bending roots, LRP stages from I to VIII, in accordance with previous reports, were assessed every 6 hours for 0 to 54 hours after gravity stimulation and are represented here as a percentage of the total number of observed LRP at each time point. At least 70–80 LRP were observed at each time point. (B, C) All class 1 XTH gene expression patterns at each time point during LR initiation were measured every 6 hours from 6 to 54 hours pgi. Bending roots of a population of 5-day-old seedlings were microdissected at 10 time points, which were then used for RNA extraction (approximately 220 per time point for three independent replicates). Expression patterns of all class 1 XTH genes are shown. The error bars denote SDs (n = 4). Student’s t-test was applied. The asterisks (*) show statistically significant differences (p<0.05).
