In plants, transient changes in calcium concentrations of cytosol have been observed during stress conditions like high salt, drought, extreme temperature and mechanical disturbances. Calcium-dependent protein kinases (CDPKs) play important roles in relaying these calcium signatures into downstream effects. In this study, a stress-responsive CDPK gene, ZoCDPK1 was isolated from a stress cDNA ge...

Frequent monitoring of stress levels in turfgrass is key to maintaining healthy turfgrass stands. Current methods used to monitor turfgrass for drought and salinity stress can be time consuming and expensive. This study was conducted to determine if data obtained from digital image analysis and spectroradiometry could accurately detect drought and salinity stress in hybrid bluegrass. Furthermor...

salvia genus has 58 annual and perennial herbaceous species in iran that 17 species are endemic and salvia sahendica boiss & buhse is one of them. in order to investigate the effects of drought stress caused by peg 6000 and salinity stress induced by nacl on germination factors of salvia sahendica, two experiments were carried out based on a completely randomized design with 3 replications. in ...

MYB-type transcription factors (TFs) play essential roles in plant growth, development and respond to environmental stresses. Role of MYB-related TFs of rice in drought stress tolerance is not well documented. Here, we report the isolation and characterization of a novel MYB-related TF, OsMYB48-1, of rice. Expression of OsMYB48-1 was strongly induced by polyethylene glycol (PEG), abscisic acid ...

the effects of drought and salinity stress on the growth and chemical compositions pennyroyal(mentha pulegium l.) plant were investigated. this experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (fc)) and five salt treatments with 0, 25, 50, 75 ...

continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

Although deemed a "non-essential" mineral nutrient, silicon (Si) is clearly beneficial to plant growth and development, particularly under stress conditions, including salinity and drought. Here, we review recent research on the physiological, biochemical, and molecular mechanisms underlying Si-induced alleviation of osmotic and ionic stresses associated with salinity and drought. We distinguis...

BACKGROUND NAC proteins (NAM (No apical meristem), ATAF (Arabidopsis transcription activation factor) and CUC (cup-shaped cotyledon)) are plant-specific transcription factors reported to be involved in regulating growth, development and stress responses. Salinity responsive transcriptome profiling in a set of contrasting finger millet genotypes through RNA-sequencing resulted in the identificat...
