Synechocystis salt-responsive gene 1 (sysr1) was engineered for expression in higher plants, and gene construction was stably incorporated into tobacco plants. We investigated the role of Sysr1 [a member of the alcohol dehydrogenase (ADH) superfamily] by examining the salt tolerance of sysr1-overexpressing (sysr1-OX) tobacco plants using quantitative real-time polymerase chain reactions, gas ch...
Understanding the reaction form and biochemical response of wheat cultivars about the salinity stress can help to better understand the defense mechanisms and identify the indicators and biomarkers of tolerance screening for salinity stress in this strategic plant and other field crop. For this purpose, biochemical traits related to salinity tolerance of wheat cultivars were evaluated as a f...
Barley is one of the oldest cultivated crops in the world with a high adaptive capacity. The natural tolerance of barley to stress has led to increasing interest in identification of stress responsive genes through small/large-scale omics studies, comparative genomics, and overexpression of some of these genes by genetic transformation. Two major categories of proteins involved in stress tolera...
application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. nanofertilizers application could be a suitable way to reduce these problems. accordingly, in order to assess the silicon nanopar...
Regarding the practical farming of Litopenaeus vannamei, the deterioration of water quality from intensive culture systems and environmental pollution is a common but troublesome problem in the cultivation of this species. The toxicities that result from deteriorating water quality, such as that from ammonia stress, have lethal effects on juvenile shrimp and can increase their susceptibility to...
Salinity stress is an important environmental constraint limiting the productivity of many crops worldwide. In this report, experiments were conducted to investigate the effects of seed presoaking by bovine hemoglobin, an inducer of heme oxygenase-1 (HO-1), on salinity tolerance in rice (Oryza sativa) plants. The results showed that different concentrations of the hemoglobin (0.01, 0.05, 0.2, 1...
Different clones of the wetland grass Phragmites australis differ in their morphology and physiology, and hence in their ability to cope with environmental stress. We analysed the responses of 15 P. australis clones with distinct ploidy levels (PLs) (4n, 6n, 8n, 10n, 12n) and geographic origins (Romania, Russia, Japan, Czech Republic, Australia) to step-wise increased salinity (8, 16, 24, 32, 4...
Too much salt can do terrible things to a plant. Dissolved in solution, salt reduces the availability of water to the plant. Also, excess Na in high-salinity soil competes with K for uptake across the plasma membranes of plant cells, reducing plant growth and causing cellular injury and even death. Indeed, salinity tolerance is correlated with the ability of a plant to retain proper tissue K le...
The mechanism of abiotic stress tolerance is crucial for plants to survive in harsh condition and the knowledge of this mechanism can be use to solve the problem of declining productivity of plants or crops around the world. However in-depth description is still unclear and it is argued, in particular that there is a relationship between high salinity tolerance and the ability to tolerate high ...
Low quality of irrigation water along with increasing salinity level has reduced the olive yield over recent years in Iran. Screening of salinity tolerance in olive cultivars using gas-exchange parameters, water use efficiency, and relative leaf chlorophyll content are important in olive development programs. This study was carried out to assess the salinity tolerance of four olive cultivars (A...
