Happy almost Friday from the US’s west coast, everybody! I recently finished reading “Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge, and the Teachings of Plants” by Robin Wall Kimmerer and plants have been on my mind so today’s Digest is heavy on the plant microbiome research. Two plant papers I found especially fascinating applied different experimental designs to study the same issue: one looks at how the mono-cropping of maize negatively impacts soil microbial communities and the other found that sugarcane/peanut intercropping enriches for beneficial microbes that promote nitrogen and phosphate release from the soil. There are also several papers looking at the relationship between microbes and the host immune system and an eLife paper in which the popular shelter-in-place hobby of making sourdough and our beloved microbiome field collide. Happy reading!
