The merger of two polyploids is better than the sum of their parts

Plant evolutionary biologists from the Department of Botany (Roswitha Schmickl and Magdalena Bohutínská), together with collaborators from the United Kingdom (John Innes Centre and the Universities of Nottingham, Leicester and Cambridge), found an intriguing role of introgressive hybridisation in adaptation to whole genome duplication (WGD). Specific, bidirectional adaptive gene flow affected loci known to be essential for processes that are impacted by WGD: meiotic stability, endopolyploidy, and transcription. The paper was recently published in Nature Communications.

Popular Science: Subglacial silicon as another player in global nutrient cycling

As recently published in Nature, methane released from subglacial meltwater is a significant source of greenhouse gas emissions to the atmosphere. However, it is not only subglacial methane which is responsible for changes in greenhouse gas concentrations. The international team of scientists, in collaboration with three polar ecologists from the Department of Ecology, found that there is another important nutrient influencing atmospheric greenhouse gas concentrations, fortunately by the utilization of carbon dioxide. The name of this player is Silicon.
