Transgenic expression of TaMYB2A confers enhanced tolerance to multiple abiotic stresses in Arabidopsis
Osmotic stresses such as drought, salinity, and cold are major environmental factors that limit agricultural productivity. Transcription factors play essential roles in abiotic stress signaling in plants. Three T...

Insect symbiotic bacteria harbour viral pathogens for transovarial transmission
Many insects, including mosquitoes, planthoppers, aphids and leafhoppers, are the hosts of bacterial symbionts and the vectors for transmitting viral pathogens1–3. In general, symbiotic bacteria can indirectly af...

Open AccessGelsolin of insect vectors negatively regulates actin-based tubule motility of plant reoviruses
Most plant reoviruses encode a type of nonstructural protein that assembles tubular structures to package virions for viral spread in planthopper or leafhopper vectors. These tubules are propelled by actin fil...

Open AccessPolyamine-metabolizing enzymes are activated to promote the proper assembly of rice stripe mosaic virus in insect vectors
Both viruses and host cells compete for intracellular polyamines for efficient propagation. Currently, how the key polyamine-metabolizing enzymes, including ornithine decarboxylase 1 (ODC1) and its antizyme 1 ...

Autophagy mediates a direct synergistic interaction during co-transmission of two distinct arboviruses by insect vectors
Multiple viral infections in insect vectors with synergistic effects are common in nature, but the underlying mechanism remains elusive. Here, we find that rice gall dwarf reovirus (RGDV) facilitates the trans...

Open AccessThe mRNA surveillance factor Pelo restricts rice virus propagation in insect vectors and host plants
Many devastating plant viruses are transmitted by insect vectors among plant hosts in a persistent-propagative manner. Pelota (Pelo) is an evolutionarily conserved protein involved in the mRNA surveillance sys...
