This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Plants host a variety of soil microbes on their roots. This root microbiome can affect plants in different ways, including the production of hormones to spur plant growth. In turn, plants also alter the root microbiome, which has been shown to be affected by plant genotype. But it’s been unclear whether the root microbiome is influenced by plant epigenetic factors, which regulate the readouts of genetic information. In the model organism Arabidopsis thaliana, new DNA methylation, an important epigenetic mark, occurs through the RNA-directed DNA methylation (RdDM) pathway. So researchers decided to look for changes in the root microbiota among mutant Arabidopsis plants defective in the canonical RdDM pathway. In the dcl234 triple mutant, which has defects in three Dicer-like proteins that produce small RNAs, the team found an altered microbiome composition. Mutations in other examined parts of the RdDM pathway, however, did not result in changes to the microbiome..."
