To withstand ever-changing environmental stresses, plants are equipped with phytohormone-mediated stress resistance mechanisms. Salt stress triggers abscisic acid (ABA) signaling, which enhances stress tolerance at the expense of growth. ABA is thought to inhibit the action of growth-promoting hormones, including brassinosteroids (BRs). However, the regulatory mechanisms that coordinate ABA and...

In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...

The gas molecule nitric oxide (NO) can cooperate with ethylene to tightly modulate plant growth and stress responses. One of the mechanism of their crosstalk is that NO is able to activate ethylene biosynthesis, possibly through post-translational modification of key enzymes such as ACC synthase and oxidase by S-nitrosylation. In this paper, we focus on the crosstalk of NO with ethylene signali...

In this study, selenite ions were reduced to selenium nanoparticles using a leaf extract of barley (Hordeum vulgare L.) plants. Characterization of synthesized nanoparticles using Scanning Electron Microscopy (SEM) and UV-visible spectrophotometry indicated the formation of variable size of selenium nanoparticles, suggesting that leaf extract could form polydispersed nanoparti...

The aim of this work was to investigate the effect of different concentrations of NaCl (0 mM, 100 mM, 200 mM and 300 mM) on germination, seedling growth and acid phosphatase activity of Linum usitatissimum seeds. Flax seeds were germinated under control and saline (100, 200 and 300 mM NaCl) conditions and the effect of salt stress on germination and enzyme activity was determined. Final germina...

Maintaining cellular Na(+)/K(+) homeostasis is pivotal for plant survival in saline environments. However, knowledge about the molecular regulatory mechanisms of Na(+)/K(+) homeostasis in plants under salt stress is largely lacking. In this report, the Arabidopsis double mutants atrbohD1/F1 and atrbohD2/F2, in which the AtrbohD and AtrbohF genes are disrupted and generation of reactive oxygen s...
