Plant responses to salinity are complex, especially when combined with other stresses, and involve many changes in gene expression and metabolic fluxes. Until now, plant stress studies have been mainly dealt only with a single stress approach. However, plants exposed to multiple stresses at the same time, a combinatorial approach reflecting real-world scenarios, show tailored responses complete...
DOR: 98.1000/2383-1251.1398.6.1.11.1. 1575.41 Extended Abstract Introduction: Strangle wort (Cynanchum acutum) is a perennial weed that could be propagated by seeds and vegetative organs. This brings about harvesting problems for some crops such as cotton, sugar beet, wheat and maize. In recent years, this weed has caused huge losses in sugar cane fields. The role of environmental condition...
Beneficial effects of silicon (Si) on growth and development have been witnessed in several plants. Nevertheless, studies on roses are merely reported. Therefore, the present investigation was carried out to illustrate the impact of Si on photosynthesis, antioxidant defense and leaf proteome of rose under salinity stress. In vitro-grown, acclimatized Rosa hybrida 'Rock Fire' were hydroponically...
the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...
Floral transition is coordinately regulated by both endogenous and exogenous cues to ensure reproductive success under fluctuating environmental conditions. Abiotic stress conditions, including drought and high salinity, also have considerable influence on this developmental process. However, the signaling components and molecular mechanisms underlying the regulation of floral transition by env...
Salinity is one of the environmental stresses that affects bread wheat grain yield in most parts of the world. One of the basic strategies to mitgiate the effect of non-biological stresses such as salinity is genetic improvement of crop plants. Identification of stress-associated genes is a prerequisite for genetic improvement. In the present study, the role of a number of genes in the aquapori...
Drought and salinity are two major environmental factors adversely affecting plant growth and productivity. However, the regulatory mechanism is unknown. In this study, the potential roles of small regulatory microRNAs (miRNAs) in cotton response to those stresses were investigated. Using next-generation deep sequencing, a total of 337 miRNAs with precursors were identified, comprising 289 know...
Plants are exposed to various environmental stresses during their life cycle such as salt, drought and cold. Natural variation mediated plant growth adaptation has been employed as an effective approach in response to the diverse environmental cues such as salt stress. However, the molecular mechanism underlying this process is not well understood. In the present study, a collection of 82 Arabi...
Salinity stress is one of the important limiting factors in agricultural crops production. In order to evaluate salicylic acid (SA) application effects on lettuce growth parameters under salinity stress condition, a factorial experiment in a randomized complete block design (RCBD) with three replications was carried out in greenhouses, Faculty of Agriculture, University of Ilam, Iran. Factors e...
In order to survey on effects of dietary Thyme (Thymus vulgaris) extract on common carp 180 Fish with average weight of 10.84±0.063 were divided into four groups with three replicates (each replicate with 15 fihs), and fed with different levels of dietary Thyme extract including 0, 0.5, 1 and 2 % for 70 days. At the end of rearing period 30 fish from each group were exposed to 13 ppt sea salt...
