Cnidium officinale is an important medicinal crop grown in Asia for its pharmacological properties. In this study, tetraploid breeding was conducted to increases the content of compound and tolerance environmental conditions using vitro shoot culture C. officinale. For this, we generated plants oryzalin, a chromosome doubling agent, compared morphological traits, cytological characteristics, he...

Chitosan is one of the most abundant carbohydrate biopolymers in the world, and chitosan oligosaccharide (COS), which is prepared from chitosan, is a plant immunity regulator. The present study aimed to validate the effect of COS on inducing resistance to tobacco mosaic virus (TMV) in Arabidopsis and to investigate the potential defence-related signalling pathways involved. Optimal conditions f...

Upon inoculation with pathogenic microbes, plants induce an array of metabolic changes that potentially contribute to induced resistance or even enhance susceptibility. When analysing leaf lipid composition during the Arabidopsis thaliana-Pseudomonas syringae interaction, we found that accumulation of the phytosterol stigmasterol is a significant plant metabolic process that occurs upon bacteri...

the objective of the present study was to evaluate the effect of metal mobilizing agents, ethelynediaminetetraacetic acid (edta) and salicylic acid (sa), on the accumulation and translocation of lead (pb) and nickel (ni) by fenugreek ( trigonellafoenum-graecum l . ) plants in contaminated soil. edta and sa were amended at 100 mm and 1.0 mm respectively. pb and ni content were estimated using ic...

Salicylic acid can mitigate the impacts of salinity and drought stresses in crops. To study the effect of salicylic acid under iso-osmotic drought and salt stresses on nutrients absorption and growth of linseed (Linum usitatissimum L.), an experiment was conducted based on a completely randomized design with three replications in Yasouj University in 2016. Treatments included salinity and droug...

Immune systems distinguish "self" from "nonself" to maintain homeostasis and must differentially gate access to allow colonization by potentially beneficial, nonpathogenic microbes. Plant roots grow within extremely diverse soil microbial communities but assemble a taxonomically limited root-associated microbiome. We grew isogenic Arabidopsis thaliana mutants with altered immune systems in a wi...

this experiment was carried out as factorial based on randomized complete block design with four replications in 2011-2012 growing season. the experimental factors were selenium in four levels 0, 6, 12 and 18 g ha-1 and salicylic acid in three levels 0, 100 and 200 mg l-1. results showed that foliar application of selenium at rate of 12 and 18 g ha-1 decreased ion leakage by 11.6 and 18.8% comp...

Nicotiana benthamiana is a potential host to several plant pathogens, and immature leaves of N. benthamiana are susceptible to Phytophthora infestans. In contrast, mature leaves of N. benthamiana are weakly susceptible and show basal resistance to P. infestans. We screened a gene-silenced mature plant showing high resistance to P. infestans, designated as DS2 (Disease suppression 2). The deduce...

Background: The ubiquitous presence of salicylic (SA) acid in plant systems has been confirmed by many scientists. Salicylic is widely distributed throughout the and proposed to affect a number phyto-physiological activities. As an endogenous growth factor or hormone SA functions including florigenic thermogenic role, part plant-pathogen interaction, signal transduction, etc. Method: present in...
