conclusions the plants listed can be used as a prediction of rau management. of course, there are is no evidence for curing rau by some of these plants in allopathic medicine, and the further investigations in this area could lead to the discovery of a new drug evidence acquisition iranian medical sources were reviewed and effective plants used in the traditional treatment of rau were found and...

Plant activators activate systemic acquired resistance-like defense responses or induced systemic resistance, and thus protect plants from pathogens. We screened a chemical library composed of structurally diverse small molecules. We isolated six plant immune-inducing thienopyrimidine-type compounds and their analogous compounds. It was observed that the core structure of thienopyrimidine plays...

root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...

Systemic acquired resistance (SAR), which results in enhanced defense mechanisms in plants, can be elicited by virulent and avirulent strains of pathogens including nematodes. Recent studies of nematode reproduction strongly suggest that Meloidogyne incognita and Rotylenchulus reniformis induce SAR in cotton, but biochemical evidence of SAR was lacking. Our objective was to determine whether in...

Background & Aims: Acinetobacter baumannii is a gram-negative pathogen that causes a wide range of hospital-acquired infections. Due to its intrinsic traits and its remarkable abilities to quickly acquire resistance genes, it has become resistant to most antimicrobial agents and a major problem for hospitals. In recent years, application of lytic bacteriophages has been considered to eradicate ...

Tomato plants expressing the NahG transgene, which prevents accumulation of endogenous salicylic acid (SA), were used to study the importance of the SA signalling pathway in basal defence against Citrus Exocortis Viroid (CEVd) or Tomato Spotted Wilt Virus (TSWV). The lack of SA accumulation in the CEVd- or TSWV-infected NahG tomato plants led to an early and dramatic disease phenotype, as compa...

The NPR1 gene (No expresor de PR Genes1) and its homologues are regulators of Systemic Adquired Resistance (SAR), genes through their interaction with transcription factors allows the expression defense or proteins related to pathogenesis (PR) thus improvement resistance also considered receptors salicylic acid. To date there no records on identification analysis in Citrus latifolia. present wo...

Induced systemic resistance (ISR) and biofertilizer are two activities in plant protection from pathogens as well an alternative to the use of traditional fertilizers. The purpose study was determine other features 4 bacteria that have ability phosphate solvents produce indole siderophore compounds them inducers indicate their possibility be applied biofertilizers rice plants. This is experimen...
