sheath blight disease, caused by rhizoctonia solani ag-1 ia, is one of the most serious fungal diseases of rice, worldwide. rice resistance is a relative phenomenon and disease response varied (due to complex quantitative inheritance and high environmental diversity), so an accurate disease assessment would be difficult. to detect a reliable reaction of rice in a high level of disease developme...

The activities of the amino acid-catabolizing enzymes, serine dehydratase (EC 4.2.1.16), ornithine aminotransferase (EC 2.6.1.13), tyrosine aminotransferase (EC 2.6.1.5), and alanine aminotransferase (EC 2.6.1.12), were measured in the livers of rats bearing the Morris 7800 hepatoma for varying periods. A relatively rapid decrease in the activities of hepatic serine dehydratase and orni thine a...

the non-defoliant strain of verticillium dahliae (ss-4) was isolated from olive groves showing disease symptoms in toshan area of southern gorgan city. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and following identification it was propagated on tomato seedlings cv. rutgers. one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzani...

Prion diseases are untreatable neurodegenerative disorders characterized by accumulation of PrP(Sc), an aggregated isoform of the normal prion protein PrP(C). Here, we delivered the soluble prion antagonist PrP-Fc(2) to the brains of mice by lentiviral gene transfer. Although naïve mice developed scrapie at 175 +/- 5 days postintracerebral prion inoculation (dpi), gene transfer before inoculati...

Recently, medicinal plants have been the main source in treating malaria. Kaempferia galanga was investigated as an antioxidant, and anti-inflammation. In vivo study of K. had verified antimalarial for severe The objective this is to investigate chemoprophylactic effect, body composition, blood parameters against Plasmodium berghei. prophylactic effects were determined by employing (50; 100 200...

sunflower downy mildew, caused by plasmopara halstedii, is one of the most important diseases of this crop in west-azarbaijan, urmia. it causes economic yield losses during favorable environmental conditions. the pathogen is a polycyclic one, and it is likely that physiological changes occur in its population and subsequent appearance of new physiological races. hence, identification of the exi...

This dataset presents two series of hyperspectral images of healthy and infected apple tree leaves acquired daily, from two days after inoculation until an advanced stage of infection (11 days after inoculation). The hyperspectral images were calibrated by reflection correction and registered to match the geometry of one reference image. On the last experiment day, scab positions are provided.

in this study, the effect of salicylic acid (sa) on root knot nematode (meloidogyne javanica) pathogenicity and induction of some defense mechanisms such as polyphenol oxidase enzyme activity and total phenol accumulation were investigated in greenhouse conditions. we demonstrated that application of 5mm salicylic acid through foliar spray could induce resistance against m. javanica in tomato. ...
