Nitrogen is an essential soil nutrient for plants, and lack of nitrogen commonly limits plant growth. Soil nitrogen is typically available to plants in two inorganic forms: nitrate and ammonium. To better understand how nitrate and ammonium differentially affect plant metabolism and development, we performed transcriptional profiling of the shoots of ammonium-supplied and nitrate-supplied Arabi...

Light can penetrate several centimeters below the soil surface. Growth, development and behavior of plant roots are markedly affected by light despite their underground lifestyle. Early studies provided contrasting information on the spatial and temporal distribution of light-sensing cells in the apical region of root apex and discussed the physiological roles of plant hormones in root response...

Theoretical constructs of logical gates implemented with plant roots are morphological computing asynchronous devices. Values of Boolean variables are represented by plant roots. A presence of a plant root at a given site symbolises the logical True, an absence the logical False. Logical functions are calculated via interaction between roots. Two types of two-inputs-two-outputs gates are propos...

background: diabetes is a chronic disease that despite of medical and specific treatments has reminded as an important medical problem. various herbal were presented for treatment of diabetes. one of these plants is prosopis farcta that was used as hypoglycemic agent in traditional medicine. the aim of this study was investigation of hypoglycemic effect of prosopis farcta root in diabetes and h...

Although plant adaptation to serpentine soils has been studied for several decades, the mechanisms of plant adaptation to edaphic extremes are still poorly understood. Arbuscular mycorrhizal fungi (AMF) are common root symbionts that can increase the plant hosts' establishment and growth in stressful environments. However, little is known about the role plant-AMF interactions play in plant adap...

Heavy metals in soil, water and air is a great concern. Toxic heavy metals ultimately affect plant, Animals, and through food chain directly influence human life. In present study, the effect of heavy metals (Cu, Zn), Nfertilizers and EDTA on growth and biomass of cannibus sativa plant was evaluated. The Cu and Zn phytoextraction potential of Cannabis sativa plant under various treatments of N-...
