abstract heavy metals uptake and their distribution in plants are different. in addition to the genetic factors, environmental factors such as interactions of heavy metals with essential elements are very important on the amount of heavy metals uptake. in this study, the effects of iron and manganese on accumulation of cadmium in shoot and root of sunflower and corn in different concentration o...
Oligonucleotide-based microarrays with accurate gene coverage represent a key strategy for transcriptional studies in orphan species such as sunflower, H. annuus L., which lacks full genome sequences. The goal of this study was the development and functional annotation of a comprehensive sunflower unigene collection and the design and validation of a custom sunflower oligonucleotide-based micro...
phytoremediation has gained increasing attention in recent years because of its ability to clean up and redevelop brownfield sites. petroleum hydrocarbon-contaminated sites are among most prevalent industrial sites in iran as one of the top oil producers in the world, which are in great need of remediation to prevent associated environmental and human health risks. a greenhouse study was conduc...
Sunflower is an important oilseed crop, as well as a model system for evolutionary studies, but its 3.6 gigabase genome has proven difficult to assemble, in part because of the high repeat content of its genome. Here we report on the sequencing, assembly, and analyses of 96 randomly chosen BACs from sunflower to provide additional information on the repeat content of the sunflower genome, asses...
field experiment was conducted to assess the efficacy of wheat residues and different densities of sunflower in weed control during 2007 growing season. the experimental design was a randomized complete block with three replications. the experiment was set up in factorial arrangement, amount of 0, 1250, 2500, 3750, 5000 kg ha-1 of wheat residue and burning of residue (5000 kg ha-1) were the lev...
A new method to quantify, monitore and assess ecological structures and functions is the application of graph theory. In ecology, this theory demonstrates its suitable application in assessment of ecological connectivity. Connectivity is the structural attribute of landscape which facilitates the species movement among their habitats. Using graph theory, this paper aims to assess the connectivi...
Development, survivorship, longevity, reproduction, and life table parameters of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar), were examined in the laboratory using three host plants, sunflower (Helianthus annuus L.), Chrysanthemum morifolium L., and euonymus (Euonymus japonica Thurb.). Females deposited similar-sized egg masses on all three plants. Hatching was highest with...
This study investigated the effects of cocoa butter and sunflower oil alone and in combination on performance, some biochemical parameters, immunoglobulin, and antioxidant vitamin status in Wistar rats. Forty-eight male rats were assigned to four groups, consisting of 12 rats with 3 replicates. Control received balanced rat diet without oil, cocoa butter group received 3.5% cocoa butter, sunflo...
Sunflower has historically been an important crop in Central Queensland. In recent years the sunflower area in Central Queensland has been reduced due to low and variable prices and increased competition from alternate summer crops. Issues of tall persistent stubble that provides little ground cover and a lack of in-crop weed control options have also contributed to declining popularity of sunf...
BACKGROUND Respiratory allergy triggered by pollen allergens is increasing at an alarming rate worldwide. Sunflower pollen is thought to be an important source of inhalant allergens. Present study aims to identify the prevalence of sunflower pollinosis among the Indian allergic population and characterizes the pollen allergens using immuno-proteomic tools. METHODOLOGY Clinico-immunological te...
