Cytonuclear incompatibility
Webcytonuclear incompatibility; genomic conflict; mitochondria; mitochondrial RNA polymerase; Tigriopus californicus. Abstract Organismal fitness requires functional integration of nuclear and mitochon-drial genomes. Structural and regulatory elements coevolve within lineages and several studies have found that interpopulation … Webloss of fitness as a result of cytonuclear incompatibilities, reducing the role of cytonuclear incompatibility in reproductive isolation and speciation. These dynamics are likely to be important in many plant taxa, as biparental inheritance frequently occurs in taxa that exhibit cytonuclear incompatibility (reviewed in Jansen & Ruhlman, 2012).

Publication types … WebJun 16, 2016 · In particular, cytonuclear incompatibility can contribute to the maintenance of disequilibria and influence the extent and pattern of introgression in populations23. Populus albaL. (white poplar) and P. tremulaL. (European aspen) are ecologically and morphologically well-differentiated species24,25,26.
WebThis asymmetric mortality mirrored the proportion of chlorotic seedlings, and is congruent with cytonuclear incompatibility. We found no evidence of hybridization between the lineages in regions of co‐occurrence using nuclear and plastid markers. Together, our results are consistent with the hypothesis that strong postzygotic reproductive ...
