The country's network of nuclear plants - which used to provide up to 30 per cent of the national grid's power - has been closed for intensive safety checks since the 2011 meltdowns at the Fukushima plant triggered by a tsunami in 2011.
A pipe break at a retired Duke coal plant triggered the third-worst coal ash spill in U.S. history, prompting North Carolina's Senate to ask Duke to close 33 coal ash ponds in the state within 15 years.
The changes in physiological state of the plant triggered by internal or external stimuli under natural field condition are thought to be reflected as corresponding changes in the transcriptome.
On the other hand, most proteins that did not change in abundance at the biotrophic stage of the compatible interaction were transcriptionally suppressed, suggesting a complexity of molecular mechanisms in host plant triggered by Z. tritici biotrophic growth.
Importantly, several functions appeared to be relevant for interactions with the host (pathogenic as well as mutualistic), such as the T3SS, regulation of virulence, siderophore production, sugar transport, secretion, invasion, and intracellular resistance, further supporting the hypothesis that the presence of the host plant triggers a functional diversification in the rhizosphere.
In June 2014, the U.S. EPA released its proposed rules to regulate carbon dioxide emissions from existing fossil fuel power plants, triggering considerable debate on the proposal's design and its environmental and economic consequences.
Phospholipase D has been identified as an enzyme generating secondary messengers in plants, triggering defense against bacterial attacks [ 21].
Moreover, induction of P5CDH was observed in diseased, but not resistant, cultivars of flax [ 7], nor in Arabidopsis or N. benthamiana plants triggering ETI or HR non-host resistance [ 8- 10].
To protect from aphid attack themselves, soybean plants triggered the antioxidant defense systems, in which, enzymatic antioxidants such as superoxide dismutase (SOD, 1.15.1.1), catalase (CAT, 1.11.1.6) and GPx (EC 1.11.1.9) were strongly accumulated to reduce the toxic effects of ROS.
The deadline for filing legal challenges to the U.S. Environmental Protection Agency's (EPA Clean Power Plann, which aims to limit carbon dioxide emissions from power plants, triggered a host of new lawsuits targeting the rule.
