Genes encoding defense-related proteins have been used to alter the resistance of plants to pathogens and other environmental challenges, but no single fungal gene overexpression has produced broad-spectrum stress resistance in transgenic lines. We have generated transgenic tobacco (Nicotiana tabacum) lines that overexpress the endochitinases CHIT33 and CHIT42 from the mycoparasitic fungus Tric...
Improving soil microbial activity and using symbiosis and synergistic relations between plant growth-promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF) and plants through improving nutrient uptake can cause better growth of plants especially at salinity tension condition. To investigate the effect of AMF and PGPR application on growth and some nutrient uptake by corn in differen...
this study investigates the effects of garlic extract on salinity and ph stress resistance of white leg shrimp post larvae (0.1±0.01 g). the experiment was carried out on the basis of completely random model with 5 dietary treatments which include 0 (control treatment), 1cc (treatment 1), 2cc (treatment 2), 4cc (treatment 3) and 8cc (treatment 4) per 100g food in triplicate. 1500 shrimps were r...
Canola (Brassica napus L.) is one of the most important world's oilseed crops. The salin soils and salinity is the most important environmental stress factor that affects production of rapeseed. In order to study salinity resistance in canola cultivars at seedling stage based on morphophisiyological traits and assessing relation of these traits with ISSR markers, 15 canola cultivars in two sali...
Economics has looked at the decision process of politicians but the decision process of agency staff has primarily been the purview of sociologists. Agencies affect the final form of regulations, they may enforce or ignore regulations that exist, and they provide information to the political process. Policies recommended by economists for nonpoint source pollution control are seldom supported b...
Salinity gradient energy generated by the contact between seawater and river water is one of promising renewable energies. In reverse electrodialysis (RED), salinity directly translated into electricity. The representative problem a large electrical resistance or dilute solutions. solutions are poor electrically conductive. This results in huge loss when an current passes through it.
رشد جمعیت و محدودیت منابع آب ما را وادار کرده تا به دنبال روش هایی برای افزایش عملکرد محصول باشیم. از طرفی، خاک هایی که مشکل شوری دارند، تهدید جدی برای کشاورزی پایدار می باشند. بنابراین، با استفاده از روش کشت مناسب می توان علاوه بر صرفه جویی در آب مصرفی، اثرات مضر شوری را نیز کاهش داد. این مطالعه با هدف بهبود روش کشت گندم برای دست یابی به عملکرد و کارآیی مصرف آب بهتر انجام شد. برای این منظور آز...
