Salicylic acid (SA) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. The aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in Zinnia elegans plant exposed to copper stress. Effects of copper (Cu) on biomass, root length and shoo...

Litrani is a general purpose Monte-Carlo program simulating light propagation in any type of setup describable by the shapes provided by ROOT. Each shape may be made of a different material. Dielectric constant, absorption length and diffusion length of materials may depend upon wavelength. Dielectric constant and absorption length may be anisotropic. Each face of a volume is either partially o...

Jujube (Ziziphus jujube) belongs to Rhamnaceae family. It is considered not only for medicinal usage, but also is cultivated as an ornamental plant due to its beautiful leaves and trunk. The first step in a plant breeding program is to collect native genotypes of a plant in a region and evaluate them for selection of superior genotypes. Jujube is grown naturally in some areas of Iran, as well a...

One of the most important limiting factors of crop growth in the arid and semi-arid regions is water deficit. Mycorrhizal fungi is one of the most important microorganisms in the rhizosphere. The effects of these fungi apply via changes on some of the characteristics of roots and nutrients uptake in host plants under drought conditions. In order to evaluate the effect of arbuscular mycorrhizal ...

There is no functional annotation for the majority of the several hundreds of receptor-like kinases in plants. A direct way of inferring the function of these proteins is to study the phenotype that results from loss of function mutants such as T-DNA mutant lines. In this research a function (phenotype) to At2g37050 gene that encodes a receptor like kinase in Arabidopsis T-DNA line was...

understanding of wheat root system is important in dryland conditions. root development, important factor in wheat production under water limiting conditions, can be affected by environmental factors especially nitrogen fertilizer. a field experiment was carried out to study the nitrogen rates and application times on root morphology of three rainfed wheat genotypes, using a split-splitplot bas...
