In order to evaluate drought tolerance of some safflower genotypes, an experiment was conducted at the Research Farm of Isfahan University of Technology in 2016 and 2017. In this study, 18 safflower genotypes selected from different local populations along with 2 exotic cultivars and one local population (21 genotypes) were separately evaluated at two normal (non-stress) and water deficit (s...
UNLABELLED Microorganisms use a variety of metabolites to respond to external stimuli, including second messengers that amplify primary signals and elicit biochemical changes in a cell. Levels of the second messenger cyclic dimeric GMP (c-di-GMP) are regulated by a variety of environmental stimuli and play a critical role in regulating cellular processes such as biofilm formation and cellular m...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Safflower (Carthamus tinctoius L.) is an Iranian native crop that is adapted to different environmental conditions of this country. Sixteen safflower varieties/lines were spring-planted in 6 research stations including Sararood (Kermanshah), Maragheh, Ghamlo (Kordestan), Khodabandeh (Zanjan), Shirvan (North Khorasan)and Khohdasht (Lorestan) with and without drought stress conditions each in a R...
Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...
Bis-(3'-5')-cyclic dimeric GMP (c-di-GMP) is an intracellular second messenger that regulates adaptation processes, including biofilm formation, motility, and virulence in Gram-negative bacteria. In this study, we have characterized the core components of a c-di-GMP signaling pathway in the model Gram-positive bacterium Bacillus subtilis. Specifically, we have directly identified and characteri...
Two cyclic nucleotide phosphodiesterase (PDE) activities were identified in pig aortic endothelial cells, a cyclic GMP-stimulated PDE and a cyclic AMP PDE. Cyclic GMP-stimulated PDE had Km values of 367 microM for cyclic AMP and 24 microM for cyclic GMP, and low concentrations (1 microM) of cyclic GMP increased the affinity of the enzyme for cyclic AMP (Km = 13 microM) without changing the Vmax...
Cyclic di-GMP [bis-(3 -5 )-cyclic di-GMP] (Fig. 1) is a novel second messenger in bacteria that was first described as an allosteric activator of cellulose synthase in Gluconacetobacter xylinus (49). It is now established that this nucleotide is almost ubiquitous in bacteria, where it regulates a range of functions including developmental transitions, aggregative behavior, adhesion, biofilm for...
Cyclic diguanylate (c-di-GMP) is a bacterial intracellular signaling molecule. We have shown that treatment with exogenous c-di-GMP inhibits Staphylococcus aureus infection in a mouse model. We now report that c-di-GMP is an immodulator and immunostimulatory molecule. Intramammary treatment of mice with c-di-GMP 12 and 6 h before S. aureus challenge gave a protective effect and a 10,000-fold re...
In context of climate change, yield potential chickpea is hampered by heat stress. Increasing area rice fallows, shifting in cropping system and global warming, needs to identify the genotypes tolerant high temperature. With this objective an experiment was conducted during winter (rabi) season 2020–21 at seed breeding farm Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh rando...
