Your body plays host to a microbial ecosystem that’s ever-evolving, and its composition has implications for your overall health. The same holds true for plants and their microbiomes and the relationship is of pivotal importance to agriculture.
In a paper appearing in PLOS Biology, Joseph Edwards, ’17 Ph.D. in Plant Biology, Professor Venkatesan Sundaresan, Departments of Plant Biology and Plant Sciences and their colleagues tracked root microbiome shifts throughout the life-cycle of rice plants (Oryza sativa). The research could help inform the design of agricultural probiotics by introducing age-appropriate microbes that promote traits like nutrient efficiency, strong roots and increased growth rates in the plants.

Rice farmers seeking to protect their crops from pests without high dependency on pesticides may want to consider the sustainable pest management practice known as the “banker plant system.”

First-of-its-kind research, published in Scientific Reports by a nine-member team including UC Davis agricultural entomologist Christian Nansen, indicated that attracting alternative hosts for parasitoids of rice insect pests can help protect a rice crop. The players: a grass species, a planthopper, and an egg parasitoid.
