The simultaneous occurrence of several abiotic stresses is more the rule than an exception in nature. In this study pea plants were grown as hydroponics under three salinity levels (0, 50 and 100 mM NaCl), and five concentrations of iron under the form of FeEDTA (0, 0.1, 0.25, 2-optimum concentration, and 10 mg Fe/l). The separate and combined effects of both factors on growth and concentration...

The AP2/ERF transcription factors play crucial roles in plant growth, development and responses to biotic and abiotic stresses. A total of 119 AP2/ERF genes (JcAP2/ERFs) have been identified in the physic nut genome; they include 16 AP2, 4 RAV, 1 Soloist, and 98 ERF genes. Phylogenetic analysis indicated that physic nut AP2 genes could be divided into 3 subgroups, while ERF genes could be class...

BACKGROUND Biodiesel production from marine microalgae has received much attention as microalgae can be cultivated on non-arable land without the use of potable water, and with the additional benefits of mitigating CO2 emissions and yielding biomass. However, there is still a lack of effective operational strategies to promote lipid accumulation in marine microalgae, which are suitable for maki...

Copepods are small crustaceans capable to survive in various aquatic environments. Their responses to changes in different external factors such as salinity and temperature can be observed at different integration levels from copepod genes to copepod communities. Until now, no thorough observation of the temperature or salinity effect stresses on copepods has been done by optical microscopy. In...

This study evaluated the phenolic profile and antioxidant capacity of strawberries (Fragaria x ananassa Duch., cv. Primoris) cultivated under reduction nitrogen adverse irrigation conditions (high salinity), such as those prevailing in Almeria (south-eastern Spain). The compound anthocyanin profiles were analysed by HPLC-DAD-ESI/MSn, activity. Nineteen compounds quantified, mainly ellagitannins...

In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...

breeding medics species to drought and salinity tolerant  can play an important role in herb production and pasture rehabilitation. with the aim of study of the performance of annual burr medics under drought and salinity stresses, a pot study was conducted with factorial arrangement of treatments in a randomized complete block design in shiraz university. sown seeds were two types (threshed an...

drought and salinity are two important environmental stresses limiting the crop production. in order to study the influence of drought and salinity stresses on germination characteristics of marshmallow plant seeds, two separate experiments were conducted based on completely randomized design with four replications in controlled conditions. drought stress levels were 0, -2, -4, -6 and -8 bar in...
