Talk by Sascha Laubinger
Title: "To splice or not to splice: The functions of introns for plant stress responses"
Occasion: SFB Seminar
Host: Sabine Zachgo
Start: 05.05.2022 - 16:15
Location: CellNanOs 38/201
About the speaker: The lecturer is Professor of Evolutionary Genetics of Plants at the Carl von Ossietzky University of Oldenburg.
Abstract of the talk: Intron splicing increases proteome complexity, promotes RNA stability, and enhances transcription. However, introns and the concomitant need for splicing extend the time required for gene expression and can cause an undesirable delay in the activation of genes. Due to their sessile lifestyle, plants must adapt to a plethora of environmental changes (stresses) very quickly, which likely explains the relatively high abundance of intronless genes in plant genomes compared to other higher eukaryotes. What are the fundamental differences between intronless and intron-containing genes and how are they regulated? In this talk, I will discuss mechanisms specific for intronless genes and how introns can be removed quickly in response to stresses.
