Salicylic acid (SA) is an endogenous plant growth regulator of phenolic nature that plays a key role in the regulation of plant growth, development, interaction with other organisms and in the responses to environmental stresses such as drought. An experiment was therefore, conducted to evaluation the influence of exogenous SA application on some traits of common bean under water stress conditi...
Background: It is assumed that plant growth regulators produced by beneficial bacterial species could also influence plant growth. IAA is a major plant growth regulator responsible for stimulation of plant growth. There are several microorganisms which are naturally responsible for L- tryptophan metabolism. Methods: In total, 56 indigenous morphologically distinct isolates from rice roots were ...
Background: Stevia rebaudiana Bertoni, an important anti-diabetic medicinal plant, becomes an inevitable alternative to sugar. Due to the propagation difficulties, tissue culture is the best alternative for rapid mass propagation of stevia plants. Objective: The present study was conducted to optimize a protocol for rapid micropropagation of Stevia rebaudiana by shoot tip explants and to inv...
expansins are cell wall proteins that due to changes in ph, causing the expansion of the cell wall .these proteins are causing deformation of walls through loosening hydrogen bonds between the cellulose and polymer matrix microfibrils .in this study, a root specific gene called atexpa18 -that directly affect the formation of root hairs and also its role have been proved in other parts of the p...
Ethylene is a gaseous plant hormone that most likely became a functional hormone during the evolution of charophyte green algae, prior to land colonization. From this ancient origin, ethylene evolved into an important growth regulator that is essential for myriad plant developmental processes. In vegetative growth, ethylene appears to have a dual role, stimulating and inhibiting growth, dependi...
The translationally controlled tumor protein (TCTP) is an important component of the TOR (target of rapamycin) signaling pathway, the major regulator of cell growth in animals and fungi. TCTP acts as the guanine nucleotide exchange factor of the Ras GTPase Rheb that controls TOR activity in Drosophila melanogaster. We therefore examined the role of Arabidopsis thaliana TCTP in planta. Plant TCT...
in a completely randomized design, the effect of the extract from trifolium alexandrium (0, 0.2 and 0.4%) on the germination, some morphological characteristics, photosynthetic pigments, and nutrients uptake of prosopis cineraria was evaluated. the highest germination rate and percentage (9.16 and 21%, respectively) were recorded in the 0.2% treatment. the maximum and minimum lengths of radicle...
In order to improve the quantity and quality of raisins made from Sultani seedless grapes using plant growth regulators, an experiment was conducted in a randomized complete block design in a commercial vineyard near Bonab city (West Azarbaijan Province, Iran). For this purpose, spraying was carried out at fruit set stage using a combination of CPPU and GA3. Then the produced fruits were turned...
