As a result of global warming related to the development industry and agriculture, proportion atmospheric carbon dioxide has increased, temperatures have risen unprecedented levels. result, heat stress, aridity, salinity in soil leading significant research focused on deterioration reduced agricultural productivity. Therefore, it is necessary provide means maintain crop Agricultural seeking nov...

†Background Myco-heterotrophic plants are partly or entirely non-photosynthetic plants that obtain energy and nutrients from fungi. These plants form a symbiosis with arbuscular mycorrhizal, ectomycorrhizal or saprotrophic fungi to meet their nutrient demands. † Scope This Botanical Briefing summarizes current knowledge about myco-heterotrophy, discusses its controversial aspects and highlights...

to study effect of fe and zn spraying on some characteristics of mungbean, an experiment was designed as factorial based on randomized complete block with three replications in urmia university, 2012. treatments were nutrition systems (organic, chemical, integrated and no nutrition) and micronutrients (fe, zinc, no foliar application and water spraying). the plant height, pod length, number of ...

Diabetes appears to be one of the most frequent noncommunicable diseases in the world. A permanent growth in the incidence of diabetes can be observed and according to the International Diabetes Federation (IDF) the year 2030 will mark the increase in the number of diabetics to 439 mln worldwide. Type 2 diabetes accounts for about 90% of all diabetes incidence. Nutrition model modification not ...

Iron deficiency is among the most common nutritional disorders in plants. To cope with low iron supply, plants with the exception of the Gramineae increase the solubility and uptake of iron by inducing physiological and developmental alterations including iron reduction, soil acidification, Fe(II) transport and root-hair proliferation (strategy I). The chlorotic tomato fer mutant fails to activ...

Under normal conditions of growth, riboflavin is synthesized by all higher plants and is utilized as a prosthetic group by various flavoprotein enzymes (12). Pound and Welkie (11) observed the presence of a yellow pigment in the nutrient solution of tobacco plants grown in the absence of iron. Physical and chemical tests indicated that the pigment was riboflavin, and it was suggested that the d...

Different forms of nitrogen (N) fertilizer affect disease development; however, this study investigated the effects of N forms on the hypersensitivity response (HR)-a pathogen-elicited cell death linked to resistance. HR-eliciting Pseudomonas syringae pv. phaseolicola was infiltrated into leaves of tobacco fed with either NO₃⁻ or NH₄⁺. The speed of cell death was faster in NO₃⁻-fed compared wit...

BACKGROUND Abiotic stresses are serious threats to plant growth, productivity and result in crop loss worldwide, reducing average yields of most major crops. Although abiotic stresses might elicit different plant responses, most induce the accumulation of reactive oxygen species (ROS) in plant cells leads to oxidative damage. L-ascorbic acid (AsA, vitamin C) is known as an antioxidant and H2O2-...

In their natural environment, plants are part of a rich ecosystem including numerous and diverse microorganisms in the soil. It has been long recognized that some of these microbes, such as mycorrhizal fungi or nitrogen fixing symbiotic bacteria, play important roles in plant performance by improving mineral nutrition. However, the full range of microbes associated with plants and their potenti...
