The rates of two types of somatic mutations (FSMs; top row; a, and d) and ICRs (middle and bottom rows; b, e, c, f) in the progeny (seedlings) from reciprocal crosses of heat- (one hour at 32 °C) or cold- (one hour 12 °C) stressed wild type parents (male or female, as indicated by gender symbols) with one of three detector lines: G10 (FSMs); or 651 and R2L1 (ICRs). 22 °C controls for each treatment are also included. Crosses were carried out on wild type parents who were, at the time of pollination, aged 40 DAS (LHS graphs) or 45 DAS (RHS graphs). Numbers at the bottom of each column indicate the number of seedlings analyzed. Point predictions and 95% confidence intervals for SM rates are drawn. Solid lines represent any significantly different comparisons within a specific treatment of the 12 °C or 32 °C rates to the 22 °C control (e.g. in 3 Ci); dashed lines represent any significantly different comparisons, within a specific treatment, of 12 °C and 32 °C rates (e.g. within aii). The only other type of comparison made was between the rates of the male and female control treatments for a given detector line and parental age. For these, any statistically significant difference is indicated by a dotted line (e.g. between fi and fii). * – P < 0.05; ** – P < 0.01; *** – P < 0.001; no asterisked line – no significant difference. P values are corrected for multiple testing
