Cytonuclear incompatibility
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 ... WebMay 28, 2014 · This is supported by the finding by Gagnaire et al.

Webcytonuclear incompatibility in interspecific hybrids comes from differences in the fitness of reciprocal hybrids (e.g., Edmands and Burton 1999; Tiffin et al. 2001). WebCytonuclear incompatibilities are proposed to be among the first genetic barriers to arise during speciation. Accordingly, reproductive isolation (RI) within species should be …
WebJun 10, 2024 · The researchers showed that the cause of the incompatibility was light-dependent misregulation of the chloroplast psbB operon. Unlike wild-type plants, AB-I plants could not acclimate to high light by increasing chlorophyll content and redox-active components of the electron transport system.

WebDec 18, 2024 · The genetics underlying Cyto-Nuclear Incompatibility (CNI) was studied in Pelargonium interspecific hybrids. We created hybrids of 12 closely related crop wild relatives (CWR) with the ornamental P. × hortorum. Ten of the resulting 12 (F 1) interspecific hybrids segregate for chlorosis suggesting biparental plastid inheritance.
