Calcitonin gene-related peptide (CGRP) expression is markedly reduced in dorsal root ganglia neurons in the spontaneously hypertensive rat (SHR). This decrease in such a potent vasodilator may contribute to the elevated blood pressure. Therefore, the purpose of this study was to determine whether stimulation of neuronal CGRP expression in SHR, by means of the administration of nerve growth fact...

The aims of the present study were to investigate the effect of Gokshura and nettle root extracts on growth rate and sex reversal in Convict cichlid fish. Seven-day hatchlings were immersed in water containing 0 (Control, T1), 200 mg/l nettle root extract (T2), 300 mg/l nettle root extract (T3), 10 mg/l Gokshura extract (T4) and 10 mg/l Gokshura plus 200 mg/l nettle root extracts (T5) for two m...

Seven allelochemicals, namely R-(+)-limonene (A), vanillin (B), xanthoxyline (C), vanillic acid (D), linoleic acid (E), methyl linoleate (F), and (±)-odorine (G), were investigated for their herbicidal activities on Chinese amaranth (Amaranthus tricolor L.). At 400 μM, xanthoxyline (C) showed the greatest inhibitory activity on seed germination and seedling growth of the tested plant. Both vani...

For several years, we have noticed that plant growth-promoting rhizobacteria (PGPR), which consistently promote plant growth in greenhouse tests during spring, summer, and fall, fail to elicit plant growth promotion during the midwinter under ambient light conditions. This report tests the hypothesis that photoperiod regulates elicitation of growth promotion and induced systemic resistance (ISR...

water deficit stress permanent or temporary limits the growth and distribution of natural vegetation and performance of plants more than other environmental factors. in order to investigate the effect of drought stress and mycorrhizal-arbuscular fungi inoculation on the growth and yield of savory (satureja hortensis l.) a factorial experiment based on completely randomized design were conducted...

one of the important mechanisms utilized by the plant growth promoting rhizobacteria (pgpr) is lowering of ethylene levels by the 1-aminocyclopropane-1-carboxylic acid (acc) deaminase enzyme. the mechanism facilitates plant growth and development in the stress conditions. pgpr containing acc deaminase can promote plant growth under stress and overcome the harmful effects. the study aimed to scr...

BACKGROUND Methods exist to quantify the distribution of growth rate over the root axis. However, non-destructive, high-throughput evaluations of total root elongation in controlled environments and the field are lacking in growth studies. A new imaging approach to analyse total root elongation is described. SCOPE High pixel resolution of the images enables the study of growth in short time i...

in order to evaluate the effect of freezing stress on electrolyte leakage of three mooseers’ (allium altissimum regel.) ecotypes (shirvan, kalat and tandoureh), a factorial experiment based on completely randomized design with three replications was carried out under the controlled conditions in the faculty of agricultural, ferdowsi university of mashhad, iran, during 2009. plants were grown in...
