Cytonuclear responses to genome doubling
WebThe planned research will investigate this underexplored aspect of genome duplications, with implications for how cellular energetics, which play a key role in growth, reproduction, and yield, are altered in the wake of genome doubling events. The research will use a diverse panel of important crop systems and state-of-the-art genomics techniques. 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 …
