Mobile small RNAs in interspecies communication:
Small RNA-mediated gene silencing is a powerful mechanism conserved across diverse eukaryotes including plants, fungi, and animals. Emerging evidence suggests that small RNAs function not only within an organism but can also be trafficked to other interacting organisms where they regulate ‘non-self’ gene expression. Using the parasitic plant Cuscuta, we demonstrated for the first time the evidence of such interspecies regulatory small RNAs in plant - plant communication (Shahid et al., 2018, Nature). Our goal is to understand how interspecies small RNA trafficking influences diverse host – parasite/symbiont interactions, and develop RNA-based solutions for improved parasite resistance in crops.
De novo chromatin modification and epigenetic memory in plant parasitism:
Genomes harbour many hidden regulatory elements that can influence gene expression and reshape genome structure. These include transposable elements (TEs) which are ubiquitous DNA fragments that can move within and across genomes, thereby causing structural variations/mutation. Host genomes usually repress TE activity through chromatin modifications and RNA silencing pathways. However, TEs often escape this silencing during biotic/abiotic stress and certain developmental transitions. We are interested in how TE activity and chromatin modifications shape host – parasite interactions, trigger epigenetic memory, and facilitate host/parasite adaptation.We use bioinformatics, genomics, molecular and synthetic biology approaches to address the above research questions.
