The data per phenotype categories are detailed in Additional File 2 – Table S4. The statistical analysis of the data utilized Fisher’s Exact Test (* compared hAT vs. nAT and # compared the mutant vs. wild type). To ensure the reliability of our results, ovules from each genotype and condition were examined across three replicates. The significance levels in the results are denoted as follows: * significant temperature effect. # significant genotype effect. The p-value ranges are specified as # for p-values between 0.05 and 0.01, ** ## for p-values between < 0.01 to 0.0001, and *** ### for p-values lower than 0.0001
