seed germination is the most sensitive growth stages of the plant to salinity stress. seeds of many species produce a jelly-like layer called mucilage upon exposure to water. the purpose of this study was to determine the role of mucilage in increasing salinity tolerance of lallemantia ibrica. seeds of this plantcontain mucilage that can be used to treat some diseases such as neurological, live...

fennel (foeniculum vulgare mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds andmedicinal uses. as the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mm nacl), nitrogen and iron deficiency (0 n, 0.5 n of hoagland’s solution, 0 fe and 0.5 fe ofhoagland’s solution), 2°c cold (2, 3 and 4 h) and drought (3, 5...

Pulses are a major source of dietary protein for the largely vegetarian population of India. However, the production of pulses is limited because of heavy losses due to biotic (viral) and abiotic stresses such as salinity of the soil. Therefore, the present proposal is aimed at overcoming this problem in Vigna mungo (black gram) by introducing the glyoxylase1 (gly1) gene, the over-production of...

Thellungiella, an Arabidopsis (Arabidopsis thaliana)-related halophyte, is an emerging model species for studies designed to elucidate molecular mechanisms of abiotic stress tolerance. Using a cDNA microarray containing 3,628 unique sequences derived from previously described libraries of stress-induced cDNAs of the Yukon ecotype of Thellungiella salsuginea, we obtained transcript profiles of i...

Salinity is a phenomenon challenging the plantation and growth of grape in arid and semiarid regions. During the present research, tolerance of two grape cultivars (Soltanin and Fakhri) was evaluated against various sodium chloride salinity levels (zero, 50, 100, 150, 200 and 250 mM), which was conducted based on factorial experiment in the form of Randomized Complete Design (RCD) with three re...

Lycium depressum L. is the only native tree-like life-form species inhabited in saline and alkaline regions of Turkmen Sahra located at Golestan province in Northern Iran. During past years, efforts have been made to increase vegetation cover of the area by cultivation of L. depressum L. to reduce water and wind erosions and dust storm challenges; however, the cultivation of t...

To elucidate genome-level responses to drought and high-salinity stress in rice, a 70mer oligomer microarray covering 36,926 unique genes or gene models was used to profile genome expression changes in rice shoot, flag leaf and panicle under drought or high-salinity conditions. While patterns of gene expression in response to drought or high-salinity stress within a particular organ type showed...
