Abstract
We used virus-induced gene silencing (VIGS) to identify genes playing a role in host basal defense response to C. michiganensis subsp. michiganensis infection using Nicotiana benthamiana as a model plant. A preliminary VIGS screen comprising 160 genes from tomato known to be involved in defense-rela...

Abstract
The dispersal ability of queens is central to understanding ant life-history evolution, and plays a fundamental role in ant population and community dynamics, the maintenance of genetic diversity, and the spread of invasive ants. In tropical ecosystems, species from over 40 genera of ants establish c...

Abstract
We investigated the possible roles of ROS, NO and metallothionein in tomato plant responses to copper toxicity. We found that Cu(2+) stress caused the rapid release of H(2)O(2) and chlorotic leaves, and it stunted root growth and development. Cu treatment also caused an increase in NOS enzyme activi...
