Leaf spots are one of the most commonly occurring symptoms of abiotic
During spring 2008, lower densities of fourth-fifth instars and adults were observed on those cohorts that were exposed to both biotic and abiotic
factors compared to those in the exclusion treatment (t-test, P = 0.001) (Fig.1).
Large-scale distribution patterns in the Baltic Sea display a high predictability related with the scale-specific effect of abiotic
factors such as salinity and depth on the community structure (Kautsky, 1993; Middelboe et al., 1997; Bonsdorff & Pearson, 1999).
"Identifying drought responses in the mini-core collection can help us determine potential genetic components involved in abiotic
stress tolerance," says Payton.
factors (such as temperature, nutrients, and chemicals) and biotic factors (such as the host plant and predators) can cause fluctuations in aphid populations (Minks & Harrewijn, 1989; Richardson & Lagos, 2007).
The need for the institute is highly apparent since abiotic
stresses like drought, temperature extremes, flood, salinity, mineral toxicity and nutritive deficiency are affecting Indian crops to a large extent.
MEANWHILE, BACK ON EARTH: Giora Proskurowski, a researcher at Woods Hole Oceanographic Institution, recently discovered small amounts of hydrocarbons forming through an abiotic
process deep in the Atlantic.
theorists claim the evidence shows the major oil fields in that country are directly over the fissure lines.
The SCBRG is conducting basic research into the effect of abiotic
stresses, such as herbicide run-off and increased UV exposure, on unicellular algae in natural drainage systems.
To date, and as part of Evogene's abiotic
stress tolerance program, the company has identified a set of novel gene candidates that have been shown to provide high tolerance to adverse environmental conditions in a number of model crops.
In the second section, the 5 chapters review how interactions between microbes and various natural biotic and abiotic
factors can influence the origin and evolution of virulence in microbial pathogens.
Plants frequently encounter abiotic
stresses (salinity, heavy metals, oxidative stress, etc.) that inhibit their potential for growth, development, and/or productivity.
