Abiotic stresses such as drought, cold, and salinity affect normal growth and development in plants. The production and accumulation of reactive oxygen species (ROS) cause oxidative stress under these abiotic conditions. Recent research has elucidated the significant role of ethylene response factor (ERF) proteins in plant adaptation to abiotic stresses. Our earlier functional analysis of an ER...

Effects of salinity and drought on growth, contents of proline, malondialdehyde (MDA), proteinand activity of antioxidative enzymes were studied in two Trigonella species. Seeds andexplants of T. foenum-graecum and T. aphanoneura were grown on Murashige and Skoogmedium (MS) complemented with iso-osmotic concentrations of NaCl (0, 100, 150 mM) andmannitol (0, 180, 275 mM). Growth and relative wa...

Salsola turcomanica (Litv) is a widespread wild plant species in Middle Eastern arid and semi-arid areas and is a relatively palatable halophyte species that has low establishment rate in the field. In winter 2017, in order to optimize the germination indices, its seeds were treated by scarification, stratification, scarification after stratification, gibberellic acid, potassium nitrat...

abstract in order to study the effect of environmental factors (light, temperature, salinity and drought stress, acidity and burial depth) on germination and emergence of eastern dodder (cuscuta monogyna vahl), experiments were conducted at the research laboratory of faculty of agriculture, birjand university in 2009. results showed that seeds of this parasite weed had identical germination und...

Salt- and drought-induced alterations in citrulline were assessed in 4 local melon genotypes, 2 sensitive (CU-52, CU-94) and 2 tolerant (CU-196, CU-280), grown in vermiculite in a growth chamber. Salt and drought stresses were started using 30-day-old plants, with 250 mM NaCl and 45 mM PEG (-1.0 MPa) and continued for 12 days. After 12 days under salt and drought conditions, the citrulline cont...

Coastal economies and ecosystems have historically depended on oyster reefs, but this habitat has declined globally by 85% because of anthropogenic activities. In a Florida estuary, we investigated the cause of newly reported losses of oysters. We found that the oyster reefs have deteriorated from north to south and that this deterioration was positively correlated with the abundance of carnivo...

Drought and salinity, which can alter the water balance, disrupt ionic equilibrium, create reactive oxygen species (ROS), are capable of destroying plant tissues. In this study, transcriptomics, proteomics, metabolomics have been used to elucidate various abiotic stress responses. transcriptional signaling pathways, abscisic acid (ABA) is one phytohormones that regulate response. On other hand,...

effects of salinity and drought on growth, contents of proline, malondialdehyde (mda), proteinand activity of antioxidative enzymes were studied in two trigonella species. seeds andexplants of t. foenum-graecum and t. aphanoneura were grown on murashige and skoogmedium (ms) complemented with iso-osmotic concentrations of nacl (0, 100, 150 mm) andmannitol (0, 180, 275 mm). growth and relative wa...

both soil and water salinity is one of the main reasons in decreasing germination, seedling growth and establishment in many arid and semiarid parts of world especially in our country. for this reason in order to evaluate the effect of lentil seed size on germination and seedling growth properties that was under effect of salinity stress, a completely randomized design with factorial arrangemen...
