Potato Responds to Salt Stress by Increased Activity of Antioxidant Enzymes

To understand the response of potato to salt stress, antioxidant enzyme activities and ion content were analyzed for a sensitive and a tolerant cultivar. Nodal cuttings of the tolerant cultivar, Kennebec, and the sensitive cultivar, Concord, were exposed to media without or with 30, 60, 90 or 120 mmol/L NaCI for 4 weeks. On exposure to NaCI, the length and fresh and dry weight of both shoots and roots of Concord showed greater decrease than those of Kennebec. The decrease in shoot growth was more severe than that of the root for both cultivars. The K^＋ content of shoots and roots of both cultivars was reduced in a dose-dependent manner by exposure to NaCl; the Na^＋ content increased. Activities of ascorbate peroxidase, catalase and glutathione reductase were increased in NaCl-exposed shoots of Kennebec; the corresponding activities in NaCI-exposed shoots of Concord were decreased. Roots of both cultivars showed similar changes in the activities of these enzymes on exposure to NaCI. These studies established that enzyme activities in Concord shoots are inversely related to the NaCI concentration, whereas those in Kennebec do not show a dose dependency, which is also the case for the roots of both cultivars. Our findings suggest that an increase in activity of antioxidant enzymes, such as ascorbate peroxidase, catalase and glutathione reductase, can contribute to salt tolerance in Kennebec, a salt resistant cultivar of potato.

OPTIMIZED REVERSIBLE ARITHMETIC LOGIC UNITS

引用

Journal of Electronics(China) 2014年第5期31卷 394-405页

作者： Payman Moallem Maryam ehsanpour ali Bolhasani Mehrdad Montazeri Department of Electrical Engineering University of Isfahan Department of Computer Falavarjan Branch Islamic Azad University Department of Computer Arak Branch Islamic Azad University Department of Computer Faculty of Engineering Polytechnic University of Turin

Arithmetic Logic Unit(ALU) as one of the main parts of any computing hardware plays an important role in digital computers. In quantum computers which can be realized by reversible logics and circuits, reversible ALUs should be designed. In this paper, we proposed three different designs for reversible 1-bit ALUs using our proposed 3×3 and 4×4 reversible gates called MEB3 and MEB4(Moallem ehsanpour Bolhasani) gates, respectively. The first proposed reversible ALU consists of six logical operations. The second proposed ALU consists of eight operations, two arithmetic, and six logical operations. And finally, the third proposed ALU consists of sixteen operations, four arithmetic operations, and twelve logical operations. Our proposed ALUs can be used to construct efficient quantum computers in nanotechnology, because the proposed designs are better than the existing designs in terms of quantum cost, constant input, reversible gates used, hardware complexity, and functions generated.

Characterization of seed storage protein patterns of four Iranian Pistachios using SDS-PAGE

引用

Natural Science 2010年第7期2卷 737-740页

作者： ali Akbar ehsanpour Behrokh Shojaie Fatemeh Rostami 不详

We used SDSPAGE to evaluate and characterize the protein patterns of seed storage proteins in four pistachios cultivars (Akbari, Ahmad Aghaei, Fandoghi, and Kaleghouchi). Total protein content of pistachio seeds in all cultivars did not show any significant difference. Results of SDS PAGE pattern of a few protein bands were up regulated whereas some other bands showed down regulation. The identified protein patterns may be used protein marker for pistachio cultivars.
