The search for diverse plant growth-promoting (PGP) diazotrophic bacteria is gaining momentum as efforts are made to exploit them as biofertilizers for various economically important crops. In the present study, 17 diazotrophic strains belonging to eight different genera isolated from rice paddy fields were screened for multiple PGP traits and evaluated for their inoculation effects on canola a...

Canola (Brassica napus) grown as a selected plant species for field phytoremediation of selenium (Se) may be harvested and utilized as Se-enriched forage for marginally Se-deficient lambs and cows. Two field studies were conducted under controlled conditions to evaluate the accumulation of Se into different animal tissues, including blood, excreta, and milk. In Study 1, treatments consisted of ...

to evaluate the effect interference of mustard on yield and yield components of canola, and observation competition difference of mustard in pot and field condition, experiments were conducted in 2006 and 2007 in the greenhouse and farm of college of agriculture, ramin agricultural and natural resources university of khouzestan, respectively. pot experiment the factorial set of treatments was a...

Gene flow exposed by genetically engineered crops Gene flow is the transfer of genes between populations of the same or related species. The exchange between crop cultivars of genes selected by traditional breeding that confer characteristics such as shorter stems, higher yield, or increased seed quality will attract little attention. In the same way, crop-weed hybrids having acquired traits su...

genic crops is considered a major threat to the durability of these crops (van Rie, 1991; Gould, 1994; McGaughey, Seed mixtures are recommended as a strategy to minimize or avoid 1994). Refugia in the form of susceptible (nontranshaving insects develop resistance to insect-resistant transgenic crops. genic) plants to prevent exposure of some portion of The objective of this study was to evaluat...

Transgenic plants may prove to be one of the most economical systems for the large-scale production of proteins and peptides. Our goal is to develop an approach for protein recovery from canola that will be adaptable to a wide variety of recombinant proteins. For recombinant protein recovery, the two downstream processes considered were extraction of target protein and purification of recombina...

Salinity is a major environmental factor that influences rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effect of applied NaCl on shoot and root growth and distribution and accumulation of Na, Cl, K, Ca and Mg in the canola plant (Brassica napus L. cv: Hayola 308 and cv: PP 401) was investigated. The experiment was arranged in a completely randomi...

Delay of leaf senescence through genetic modification can potentially improve crop yield, through maintenance of photosynthetically active leaves for a longer period. Plant growth hormones such as cytokinin regulate and delay leaf senescence. Here, the structural gene (IPT) encoding the cytokinin biosynthetic enzyme isopentenyltransferase was fused to a functionally active fragment of the AtMYB...

Four bioagents i.e. yeast (Saccharomyces cerevisiae), Trichoderma viride, Bacillus subtilis, and Pseudomonas fluorescens in addition to humic acid, sulphated canola oil (sulphex 0.5%) and Paclobutrazol (PBZ) were applied to study their effect on disease incidence caused by Sclerotium rolfsii. Also, some vegetative parameters, tuber yield and enzymes activity of Jerusalem artichokes (Helianthus ...
