Biochemical variability among 20 Indian isolates of Sclerotinia sclerotiorum collected from different hosts/soil samples from different localities in India is reported. High Performance Liquid Chromatographic (HPLC) analysis of ethyl acetate fraction of culture filtrate, mycelia, sclerotia and sclerotial exudate showed 15~23 peaks but only 11 could be identified. They were tannic, gallic, oxali...

Abstract— The expression of the genes encoding inhibitors serine ( ISP ) and cysteine ​​proteinases ICP was studied in roots tomato plants resistant susceptible to root-knot nematode Meloidogyne incognita during infection under effects signaling molecules: salicylic (SA) jasmonic (JA) acids. It shown that, upon infection, are characterized by an increased accumulation transcripts at stages pene...

in order to study the effects of salicylic acid and selenium application on yield and yield components of rainfed wheat cultivars, a field experimental was carried out as factorial based on randomized complete block design with four replications in the research station of islamic azad university- arak branch, iran in 2010-2011 growing season. the treatments were salicylic acid and selenium. sal...

because of the harmful effects of the chemicals on human health and environment, the use of these compounds is recently restricted and it is necessary to use the safe compounds in postharvest technology of fruits and vegetables. in this study, the effect of salicylic acid (sa; at concentrations of 0, 1, and 2 mmol l-1) and aloe vera gel (at concentrations of 25 and 33 %1) application on posthar...

The spittlebugs Mahanarva spectabilis economically challenges cattle production of neotropical regions, due to its voracious feeding on tropical grasses. Here, we evaluated biochemical responses the interaction between M. and widely cultivated grasses Brachiaria spp. (i.e., brizantha decumbens) elephant (cvs. Roxo de Botucatu Pioneiro), regarding lipoxygenases, protease inhibitors, phytohormone...

4 2 containing FeSO and Na EDTA. EDTA could be replaced by citric acid. In this in vitro system 4hydroxybenzoic acid is hydroxylated to 3,4-dihydroxybenzoic acid (protocatechuic acid) and decarboxylated to hydroquinone. In an analogous reaction 2-hydroxybenzoic acid (salicylic acid) is hydroxylated to 2,3-dihydroxybenzoic acid and 2,5-dihydroxybenzoic acid (gentisic acid) and decarboxylated to ...

After growth of representatives of eight genera in the order Actinomycetales and two others related taxonomically to Mycobacterium under iron-deficient conditions, the following compounds were found in the media : salicylic and phenylacetic acids, but no mycobactin, with Thermoactinomyces vulgaris; 2,3dihydroxybenzoic acid with Corynebacterium equi, Mycococcus sp., Nocardia opaca and Streptospo...

Invasion of vascular endothelial cells by Staphylococcus aureus is associated with diverse complications and recurrent infection. Little is known about the effect of salicylic acid, the major metabolite of aspirin, on the interaction between S. aureus and vascular endothelial cells. We examined the adhesion of S. aureus strain 8325-4 cultured with or without salicylic acid to human umbilical ve...

Phenolic acids such as p-coumaric acid and microbial metabolites of poorly absorbed polyphenols are absorbed by the monocarboxylic acid transporter (MCT)-mediated transport system which is identical to the fluorescein/H(+) cotransport system. We focus here on the physiological impact of MCT-mediated absorption and distribution. We examined whether MCT1, the best-characterized isoform found in a...
