to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...
Innate immune receptors in plants detect the presence of microbial pathogens and trigger defense responses to terminate or restrict pathogen growth. The molecular mechanisms of receptor-mediated nonself recognition and subsequent intracellular signaling pathways have received much attention in the past. Less is known about the cellular mechanisms that contribute to the execution of immune respo...
Plant responses to pathogens depend on the rapid and effective coordination of microbial perception and downstream signal transduction events. Detection of pathogen invasion starts by the recognition of conserved microbial molecules called pathogen-associated molecular patterns (PAMPs),mainly by plantmembraneassociated extracellular receptors, which results in PAMP-triggered immunity (PTI). Usi...
Plant defence responses against pathogen infection are crucial to plant survival. The high degree of regulation of plant immunity occurs both transcriptionally and posttranscriptionally. Once transcribed, target gene RNA must be processed prior to translation. This includes polyadenylation, 5'capping, editing, splicing, and mRNA export. RNA-binding proteins (RBPs) have been implicated at each l...
Plants and animals have evolved intracellular nucleotide-binding domain and leucine-rich repeat-containing immune receptors (NLRs) to perceive non-self and trigger immune responses. Plant NLRs detect strain-specific pathogen effectors and activate immune signaling leading to extensive transcriptional reprogramming and termination of pathogen infection. Here we review the recent findings in barl...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
We show that oomycete-derived Nep1 (for necrosis and ethylene-inducing peptide1)-like proteins (NLPs) trigger a comprehensive immune response in Arabidopsis thaliana, comprising posttranslational activation of mitogen-activated protein kinase activity, deposition of callose, production of nitric oxide, reactive oxygen intermediates, ethylene, and the phytoalexin camalexin, as well as cell death...
The immune system is one of our most complex biological systems in the body. Immunization may be active or passive. The active immunization involves stimulation with an antigen to develop immunological defences against a future exposure and passive immunization involves administration of preformed antibodies to an individual who is already exposed to be exposed to an antigen. Immunomodulatory a...
Plants respond to pathogens using an innate immune system that is broadly divided into PTI (pathogen-associated molecular pattern- or PAMP-triggered immunity) and ETI (effector-triggered immunity). PTI is activated upon perception of PAMPs, conserved motifs derived from pathogens, by surface membrane-anchored pattern recognition receptors (PRRs). To overcome this first line of defense, pathogen...
Proteases are enzymes integral to the plant immune system. Multiple aspects of defence are regulated by proteases, including the hypersensitive response, pathogen recognition, priming and peptide hormone release. These processes are regulated by unrelated proteases residing at different subcellular locations. In this review, we discuss 10 prominent plant proteases contributing to the plant immu...
