Transcriptomic Insights into Host Metabolism and Immunity Changes after Parasitization by Leptopilina myrica

open access: yesInsects
Parasitoids commonly manipulate their host’s metabolism and immunity to facilitate their offspring survival, but the mechanisms remain poorly understood. Here, we deconstructed the manipulation strategy of a newly discovered parasitoid wasp, L.

Contribution of Small RNA Pathway to Interactions of Rice with Pathogens and Insect Pests

open access: yesRice, 2021
Small RNAs (sRNAs) are mainly classified into microRNAs (miRNAs) and small interfering RNAs (siRNAs) according to their origin. miRNAs originate from single-stranded RNA precursors, whereas siRNAs originate from double-stranded RNA precursors that are ...
