WebJun 9, 2024 · The plant genome is partitioned across three distinct subcellular compartments: the nucleus, mitochondria, and plastids. Successful coordination of gene expression among these organellar genomes and the nuclear genome is critical for plant function and fitness. Whole genome duplication events (WGDs) in the nucleus have … WebJul 17, 2024 · As summarized in a recent review on cytonuclear responses to genome doubling (Sharbrough et al., 2024), there are a number of potential mechanisms to maintain cytonuclear stoichiometry in polyploid plants. Elevated nuclear gene copy numbers resulting from whole-genome duplications (WGD) could be compensated by (a) more …
WebApr 7, 2024 · An excellent example of cytonuclear discordance is provided by the first-ever analysis of the Neanderthal nuclear genome : while the earlier studies of mitochondrial genomes did not reveal any evidence for human-Neanderthal hybridization, the nuclear data demonstrated clear and striking evidence to the contrary.

WebAug 9, 2024 · Although nuclear genome sizes of diploid representatives of these genera vary more than 10-fold, the number of their nuclear genes is more constant (from 26,000 in A. thaliana to ∼42,000 in Arachis ipaensis), as is typical for flowering plants ().Although this is two orders of magnitude more genes than reside in the plastid or mitochondrial …
WebCytonuclear coordination between biparental nuclear genomes and uniparental cytoplasmic organellar genomes in plants is often resolved by genetic and transcriptional cytonuclear responses. Whether this mechanism also acts in allopolyploid members of other kingdoms is not clear. Additionally, cytonuc …
