Least-squares mean (LSM) of change in expression of a meiosis-related gene in arp6-1 or arp6-2 compared to that in wild-type (WT) ovules in five technical replicates (three biological replicates) assayed by RT-qPCR. The P value is the probability value associated with a pairwise test between change in the expression of a gene in arp6-1 or arp6-2 compared to that in wild-type ovules and change in the expression of ACTIN2 in arp6-1 or arp6-2 compared to that in wild-type ovules (*P ≤ 0.05). Any pair of least-squares means that do not share the same letter are significantly different (P ≤ 0.05) from each other in pairwise comparisons for change in expression of a meiosis-related gene in arp6-1 or arp6-2 compared to that in wild-type ovules.
