Drought stress is one of the most important factors limiting production in the agricultural sector. Due to the need to use smart agriculture adapted to climate change, the use of drought-tolerant alternative plants with high water use efficiency is of great importance. Foxtail millet (Setaria italica L.) is one of the important drought tolerant fodder and food grains in semi-arid regions. In th...

The Oryza sativa L. F8 population derived from a cross between salt tolerance cv. Ahlemi Tarom and salt sensitive cv. Neda was used in the study. Germinated seeds floated on water for 3 d, and after were transferred to float on Yoshida's nutrient solution for 11 d. two weeks after sowing, the seedling was transferred to nutrient solution containing 51.19 mM NaCl (electrical conductivity 6 dSm-1...

Current research was performed to identify molecular markers associated to phonological traits including days to tillering, days to stem elongation, days to heading, days from stem elongation to heading, grain filling period and days to physiological maturity based on 407 AFLP and SSR markers in 148 barley cultivars by association mapping. This experiment was conducted in two alpha lattice desi...

hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

Salinity stress declines plant growth and its efficiency, which is leading to a substantial reduction in crop yield. Presently, the worldwide challenges are meet food consumption demand, along with decreasing productivity per unit area at same time of environment. Wheat (Triticum aestivum L.) one major cereal grain crops losses gain yield exceeds 60% due salinity stress. Now, it imperative deve...

The aim of this study was to determine the drought tolerance control loci in growth stage in bread wheat. In this regards 99 doubled haploid lines with their parents were evaluated in a randomized complete block design with three replications in two drought stress levels. Genotypes mean square for all traits in two environments was significant. Thirty three SSR markers and 24 TRAP markers which...

Cold temperature is an important abiotic stress which negatively affects morphological development and seed production in rice (Oryza sativa L.). At the seedling stage, cold stress causes poor germination, seedling injury and poor stand establishment; and at the reproductive stage cold decreases seed yield. The Rice Diversity Panel 1 (RDP1) is a global collection of over 400 O. sativa accession...

Soil salinity is a major constraint to rice production in large inland and coastal areas around the world. Modern high yielding rice varieties are particularly sensitive to high salt stress. There are salt tolerant landraces and traditional varieties of rice but with limited information on genomic regions (QTLs) and genes responsible for their tolerance. Here we describe a method for rapid iden...

In order to explore the relevant molecular genetic mechanisms of photosynthetic rate (PR) and chlorophyll content (CC) in rice (Oryza sativa L.), we conducted a series of related experiments using a population of recombinant inbred lines (Zhenshan97B x IRAT109). We found a significant correlation between CC and PR (R= 0.19**) in well-watered conditions, but no significant correlation during wat...
