Beskrivning av projektet
Average-sized genomes such as barley are >70% comprised of retrotransposons (RLXs). RTNs are activated by environmental stresses such as heat and drought, which increase due to climate change, and are replicated by a mechanism very similar to that of retroviruses. Plants exploit networked genes to respond to stresses. Many stress-responsive genes have RLXs nearby that can affect their expression. Until now assembled sequences of genome like barley have been unavailable, impeding study of RLX-gene interactions, but this became possible in 2017. We want to analyze how stresses activate RLXs and how RLXs exploit cell components for replication, move within the plant, and get inherited. We wish to learn how activation of RLXs affects expression of nearby genes and to gain a global view of the RLX life cycle, its control by the cell and environment, and its impact on genome evolution. Understanding plant responses to stress is crucial to preserving food production in under climate change.
