The present study was carried out to evaluate the effects of light and plant growth regulators on callus induction and explant browning in date palm cultivar, Estameran in in vitro condition. The explants were pretreated by an antioxidant combination (100 mgl-1 citric acid and 150 mgl-1 ascorbic acid) for 3 days in 5 °C. Then, the leaf explants were cultured in Murashige and Skoog medium (MS)...
Tuberose is one of the tropical and subtropical bulbous cut flowers cultivated extensively in most floricultural regions of Iran. Although it has a high potential for a long vase life after harvest, tuberose declines rapidly at home. In order to overcome this problem, two experiments were conducted on a local cultivar, “Goldorosht-e-Mahalat”, using a completely randomized design. To find a suit...
In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...
Jasmonic acid and its methylated ester (Methyl jasmonate) are widely found in plants, as a natural plant growth regulators. Research results show that the use of exogenous jasmonates, change physiological responses to stress in plants. Chlorid (Cl-) is considered as an essential element in plant growth. A small amount of this substance improves the performance and quality of tobacco leaf, while...
A procedure for rapid clonal propagation of Passiflora edulis Sims. f. flavicarpa Deg. (Passifloraceae) has been developed in this study. Nodal explants were sterilized with 0.1% HgCl2 and inoculated on Murashige and Skoog (MS) basal medium. The addition of 2.0 mgL(-1) 6-benzylaminopurine (BAP) to MS medium caused an extensive proliferation of multiple shoots (8.21 ± 1.13) primordial from the n...

The kinetics of mutator sweeps was followed in two independent populations of Escherichia coli grown for up to 350 generations in glucose-limited continuous culture. A rapid elevation of mutation rates was observed in both populations within 120-150 generations, as was apparent from major increases in the proportion of the populations with unselected mutations in fhuA. The increase in mutation ...
Dendritic cells (DCs) are the most potent APCs of the immune system that seed the peripheral tissues and lymphoid organs. In an immature state, DCs sample their surroundings for incoming pathogens. Upon Ag encounter, DCs mature and migrate to the lymph node to induce adaptive immune responses. The C-type macrophage galactose-type lectin (MGL), expressed in immature DCs, mediates binding to glyc...
The physico-chemical characteristics of Chambal river water in National Chambal sanctuary (Madhya Pradesh) have been studied. The stretch of Chambal river contained in the National Chambal sanctuary (located at 25 degrees 23'-26 degrees 52'N, 76 degrees 28'-79 degrees 15'E) is extending up to 600 km downstream from Kota (Rajasthan) to the confluence of the Chambal with Yamuna river (Etawah). Th...
Hospital wastewater contains pathogenic agents and hazardous compounds; so, it will cause many risks on environmental and human health of different communities. The aim of this research was to investigate the efficiency of hospital wastewater treatment plant in north of Iran. This cross-sectional descriptive research was done on four hospital wastewater treatment plant in north of Iran during 2...
