Loss-of-function of barley mildew locus o (Mlo) confers durable broad-spectrum penetration resistance to the barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh). Given the importance of mlo mutants in agriculture, surprisingly few molecular components have been identified to be required for this type of resistance in barley. With the aim to identify novel cellular factors cont...

A combination of indoor spraying and use of insecticide-treated bed nets has slashed cases of malaria, but now researchers are reporting widespread resistance of mosquitoes to the chemicals used to kill them. Agricultural pesticides appear to be playing a role in fostering this resistance.

background and aims: to evaluate the effect of temperature on wheat streak mosaic virus (wsmv) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using adl-cross (resistant) and marvdasht (susceptible) cultivars. materials and methods: results showed that incubation at 32c changed the gene expression for resistance ...

INTRODUCTION Like all living things, cattle ticks have the ability to overcome adversity in order to survive. They can adapt genetically over time so that they and their offspring build up resistance to the normal tick treatments used. This is known as tick acaricide (chemical) resistance. The prolonged or incorrect use of tick chemicals can lead to resistance in ticks, enabling the ticks to to...

context studies on experimental animals have shown liver is a common target of chemical carcinogens; this might suggest that occupational exposure to chemicals is another risk factor for hcc. however, the relationship between occupation and liver cancer has not been extensively studied, with the exception of the known association between vinyl chloride and angiosarcoma of the liver. evidence ac...
