Ascorbate (AsA)-glutathione (GSH) cycle metabolism has been regarded as the most important defense mechanism for the resistance of plants under stress. In this study the influence of salicylic acid (SA) was studied on ascorbate-glutathione pathway, S-assimilation, photosynthesis and growth of mustard (Brassica juncea L.) plants subjected to 100 mM NaCl. Treatment of SA (0.5 mM) alleviated the n...

ABSTRACT The role of bacterially produced salicylic acid (SA) in the induction of systemic resistance in plants by rhizobacteria is far from clear. The strong SA producer Pseudomonas fluorescens WCS374r induces resistance in radish but not in Arabidopsis thaliana, whereas application of SA leads to induction of resistance in both plant species. In this study, we compared P. fluorescens WCS374r ...

Stephen S. Yau Department of Computer Science and Engineering Arizona State University Tempe, AZ 85287-8809 USA E-mail: [email protected] Ubiquitous computing (ubicomp) environments often consist of many embedded or handheld devices, either mobile or stationary, communicating with each other through wireless networks to cooperatively perform certain tasks. Recent development in ubicomp provides devic...

salicylic acid (sa) and methyl jasmonate (meja) as phytohormone regulate synthesis of secondary metabolites in a wide range of plant species thereby accumulation of phenylalanine ammonia lyase enzyme (pal) and accelerate of oxygen free radicals, protein kinas and no production. the present research designed to evaluate effect of sa and meja elicitation on accumulation of phenolic compounds, fla...

This study is devoted to the formulation of the network design problem of one-way streets and the application of simulated annealing (SA) algorithm to solve this problem for a large real network. It discusses some points of views on one-way street networks, the objective function used for design, the way in which design constraints may be considered, and the traffic problems concerning one-way ...

abstract application of chemicals which activate plant defense mechanisms before pathogen attack without environmental side effects of protective chemical agents have stimulated great deal of researches in this area. one of the important crops in the world is tomato and recently recognized as a model plant for plant-pathogen interactions. tomato early blight is one of the most devastating disea...

Cadmium, a non-essential and toxic metal, negatively affects plant growth and productivity, and alters the plant's physiological processes necessary for its survival. The present study was designed to explore the individual and combined effects of calcium and salicylic acid (SA) on the morphology and physiology of Brassica juncea L. cv. Varuna under cadmium stress. The application of calcium (2...

Cellular manufacturing system, an application of group technology, has been considered as an effective method to obtain productivity in a factory. For design of manufacturing cells, several mathematical models and various algorithms have been proposed in literature. In the present research, we propose an improved version of discrete particle swarm optimization (PSO) to solve manufacturing cell ...
