Performance of improved Cassava genotypes for early bulking, disease resistance, and culinary qualities in an inland valley ecosystem
Cassava (Manihot esculenta Crantz) is commonly grown on residual moisture after rice (Oryza sativa L.) in inland valley swamps (IVS), but not much work has been done to select genotypes that could bulk early, and have high storage root yield in the ...

New and diverse sources of multiple disease resistance in Wheat
Tan spot (caused by Pyrenophora tritici-repentis) and Stagonospora nodorum blotch (SNB), (caused by Phaeosphaeria nodorum) are destructive diseases of wheat (Triticum aestivum L.). The majority of currently grown wheat varieties are susceptible to ...

Efficacy of antioxidant overproduction on fiber growth and maturation in cotton
Electron transport in plant cells inevitably results in the creation of reactive oxygen species (ROS) that can hinder metabolic processes and cause cellular damage. In spite of the gains additional antioxidants may impart to the cotton (Gossypium ...

Carboxyl and phenolic humic fractions affect pinus nigra callus growth and metabolism
A humic substance was separated into carboxyl and phenolic fractions by affinity chromatography using a weak-base amine resin. The humic extract and its fractions were analyzed for physical and chemical characteristics. Their biological effects were ...

Transport and fate of estrogenic hormones in slurry-treated soil monoliths
Received for publication October 29, 2007. The naturally occurring hormones, such as 17-β-estradiol, 17-{alpha}-estradiol, and estrone, present in livestock manure may have detrimental environmental effects if released into surface waters. In ...

Occurrence and antibiotic resistance of escherichia coli O157:H7 in a watershed in north-central Indiana
Received for publication February 11, 2008. The Wildcat Creek in north-central Indiana is an impaired stream with historically high fecal coliform counts. This study evaluated the presence of both fecal coliforms and Escherichia coli O157:H7 at five ...

Physiological responses of annual bluegrass and creeping bentgrass to contrasted levels of O2 and CO2 at low temperatures
Ice encasement and impermeable winter protective covers can induce anaerobic conditions on golf greens. We assessed plant survival and biochemical changes of annual bluegrass (Poa annua L.) and creeping bentgrass [Agrostis stoloniferous L. var. ...

Genomic selection for crop improvement
Despite important strides in marker technologies, the use of marker-assisted selection has stagnated for the improvement of quantitative traits. Biparental mating designs for the detection of loci affecting these traits (quantitative trait loci ...

Predicted genetic gain and inbreeding depression with general inbreeding levels in selection candidates and offspring
Methods for predicting response to selection in noninbred populations for individuals and family-based selection methods have been very well developed. However, theory to predict improvement of inbred lines derived from a recombined population, as ...

Cloning and characterization of a CAP gene expressed in Gossypium Arboreum Fuzzless mutant
The adenylyl cyclase-associated protein (CAP) was first identified in the budding yeast as a protein that functions in cytoskeletal organization and signal transduction. We isolated two CAP homologs from wild-type cotton Gossypium arboreum L. ...

Impact of nighttime temperature on physiology and growth of spring Wheat
Climate models predict greater increases in nighttime temperature in the future. The impacts of high nighttime temperature on wheat (Triticum aestivum L.) are not well understood. Objectives of this research were to quantify the impact of high ...

Sorption and mobility of Ivermectin in different soils
Avermectins are widely used to treat livestock for parasite infections. Ivermectin, which belongs to the group of avermectins, is particularly hazardous to the environment, especially to crustaceans and to soil-dwelling organisms. Sorption is one of ...
