This research was carried out to study the effect of TiO2 and nano-TiO2 on some chemical compounds in a medicinal plant Lallemantia iberica under water deficit conditions. The experiment was conducted as a factorial arrangement in a randomized complete block design with three replications. The first factor was the application of external materials as spraying with 3 levels of control, TiO2 and ...

attention deficit/hyperactivity disorder (ad/hd) is one of the most common neurodevelopmental disorders in childhood which involves behavioral and learning disturbances in children.  in addition, the disorder usually causes some problems in a child’s interaction with the peer group and family members. the present research addresses the comparative effectiveness of behavior parent training (bpt)...

evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...

Soybean farming has faced several losses in productivity due to drought events in the last few decades. However, plants have molecular mechanisms to prevent and protect against water deficit injuries, and transcription factors play an important role in triggering different defense mechanisms. Understanding the expression patterns of transcription factors in response to water deficit and to envi...

manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. myc2 gene encodes a key stress-related transcription factor involved in jasmonate (ja) and abscisic acid (aba) signaling pathways in arabidopsis. brassica napus, as a globally important oilseed crop, is a close relative of arabidopsis.  in the present study...

Drought, a period of abnormally dry weather, results in soil-water deficit and subsequently plant-water deficit. The lack ofwater in the environment constitutes a stresswhen it induces an injury in the plant. Water deficit in the plant disrupts many cellular and whole plant functions, having a negative impact on plant growth and reproduction. Crop yields are reduced by 69% on average when plant...

investigation of physiological responses to water deficit in sesame (sesamum indicum l.) genotypes can help to identify effective mechanisms of plant resistance to stress. therefore, chlorophyll content, proline, soluble carbohydrates, net photosynthesis rate, stomatal conductance, maximum quantum efficiency (fv/fm), plant height and shoot dry weight in a complete block factorial pot experiment...

Water-deficit stresses preferentially reduce shoot growth, thereby disrupting the flow of carbohydrates from source leaves to the developing sinks. Here, we use a novel stress bioassay to dissect responses of field and greenhouse-grown cotton (Gossypium hirsutum) source leaves to water-deficit stresses. Fifth main stem leaf samples were harvested at sunrise and subjected to a prolonged elevated...
