reduction of deleterious effects of salt stress using some plant bioregulators has been reported in different plant species. salicylic acid (sa) has been considered as a signaling molecule and it is known to ameliorate the oxidative damage caused by environmental stresses such as salt stress. the present study was conducted to investigate the effects of sa on different growth characteristics, p...
As an increasing number of plant genome sequences become available, it is clear that gene content varies between individuals, and the challenge arises to predict the gene content of a species. However, genome comparison is often confounded by variation in assembly and annotation. Differentiating between true gene absence and variation in assembly or annotation is essential for the accurate iden...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
the purpose of this quantitative study was to investigate the relation between efl teachers’ self-efficacy beliefs and their success. moreover, the study was an analysis of the teacher age, gender and years of teaching experience, to examine the manner in which these factors relate to teacher self-efficacy as defined by bandura (1997) and teaching effectiveness as evaluated by their own student...
Polyploidy plays a crucial role in plant evolution. Brassica napus (2n = 38, AACC), the most important oil crop in the Brassica genus, is an allotetraploid that originated through natural doubling of chromosomes after the hybridization of its progenitor species, B. rapa (2n = 20, AA) and B. oleracea (2n = 18, CC). A better understanding of the evolutionary relationship between B. napus and B. r...
Myrosinases are glycoproteins composed by several minor protein subunits that occur as mixtures of isoenzymes. Myrosinases catalyse the hydrolysis of glucosinolates, producing a series of degradation products with biological activity. In the experiments presented in this paper, myrosinases were purified from seeds of S. alba, B. napus and two cultivars of R. sativus with different resistance to...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Turnip mosaic virus (TuMV) infects many plant species, being the only potyvirus able to infect brassicas. TuMV isolates have been classified into 12 pathotypes according symptoms induced in lines of Brassica napus, and molecularly clustered six lineages (basal-B, basal-BR, Asian-BR, world-B, Iranian OMs). Despite considered one most important viruses infecting brassicas worldwide, there is litt...
Verticillium in oilseed rape (OSR) is known since the 1930s in Sweden and the 1980s in Germany. The pathogen, Verticillium longisporum (VL), is host-specific to the Brassica species and particularly threatens the production of OSR in intense crop rotations. In contrast to diseases induced by other Verticillium species, VL does not induce wilt symptoms in OSR but stunted growth and premature blo...
to estimate plant resistance to cadmium chloride (cdcl2) stress for phytoremediation purposes, the effect of cadmium (cd) phytotoxicity was assessed on total soluble protein, chlorophyll (chl) content and antioxidant enzymes in the leaves of three different brassica napus (b. napus) cultivars; mohican, reg.cob and okapi. plants were exposed to three levels of cdcl2 (0.75, 1.5 and 2.25 mm) in ir...
