Comparison of directions of effects of cytonuclear interacting combinations significant both in the dormancy and germination performance experiments.

Comparisona	Number of shared significant cytonuclear interacting combinations	Number of identical direction of effectsb	Number of opposite directions of effectsc
Gmax vs. 0PH	49	36	13
Gmax vs. 3PH	59	45	14
Gmax vs. 6PH	37	20	17
Gmax vs. 9PH	43	30	13

^aGmax stands for germination success in the experiment testing germination performance; xPH stands for germination success after × months PH in the dormancy experiment. ^bIdentical directions of significant effects (listed in Supplementary Table S4) correspond to identical signs of contrasts calculated as described in Supplementary Methods S1. Based on the writing of the contrasts, it indicates that the considered cytonuclear interacting combination affected germination success in the same direction in both experiments, thus dormancy and germination performance in opposite directions. ^cOn the same basis, opposite directions of the effects correspond to opposite signs of the contrast results. It indicates that the considered cytonuclear interacting combination affected germination success in opposite directions in both experiments, thus dormancy and germination performance in the same direction.
