An assessment of rhizobial infection, metabolite release and growth response in agriculturally important legume and cereal crops
… on the natural and laboratory infection of cereals by rhizobium provided the impetus to embark on research using African landraces of sorghum and millet to study their interaction with rhizobia. Seven strains of root-nodule bacteria (namely Rhizobium GHR2, Bradyrhizobium japonicum Tal 110, …

Genetic regulation of maize floral development - insights from the transcriptome and translatome
… floral organs. In grasses, including the major cereal crops, flowers (florets) are contained in spikelets, which contain one to many florets, depending on the species. Floral development in plants is regulated by gene expression. Understanding gene expression regulation in maize floral …

Automated Wheat Stem Rust Detection using Computer Vision
Wheat is one of the most important cereal crops, contributing significantly to the financial economy and food sources. Currently, the direct consumption of wheat amounts to about 41%. Additionally, in 2019 alone, the global trade value of wheat was about $39.6 billion. Hence, the protection of the …

The effect of calcium carbonate of certain soil constituents and on plant growth
… studied in crop yields, in per cent of grain in cereal crops, in inoculation of clover in the soil reaction, and in amount of nitrates present as well as the easily soluble phosphorus and potassium contained in the soil.

Identification of Candidate Effector Proteins from Fusarium graminearum during Infection of Arabidopsis thaliana Using Proximity-Dependant Biotin Identification (BioID)
… that causes Fusarium head blight (FHB) in cereal crops. Identifying proteins that are secreted from pathogens to overcome plant defenses and cause disease, collectively known as effectors, can reveal new targets for fungicides or other control measures.Proximity-dependent biotin …

WAVELENGTH AND VISUAL FEATURE SELECTION FOR NON-DESTRUCTIVE EVALUATION OF FUSARIUM HEAD BLIGHT IN WHEAT USING HYPERSPECTRAL IMAGING
… (FHB) is a fungal disease affecting the heads of cereal crops and has caused significant economic losses in the Canadian prairie wheat industry. Although wheat breeding efforts to enhance resistance genes are ongoing, efficient and accurate detection of FHB remains critical for breeding programs …

An Archaeobotanical History of Arable Agriculture in Yorkshire (4000 BCE - 1100 CE)
… (UK), spanning from the first evidence of cereal crops in ca. 4000 BCE, until 1100 CE. Yorkshire’s macrobotanical evidence has been collated and analysed using ubiquity and relative abundance analysis to establish long-term diachronic trends in cereal cultivation practices. The main …

Zearalenone contamination in swine feed and the effects on reproductive health
… Fusarium. Fusarium species commonly occur in cereal crops such as corn, wheat, barley, and rice which are used in swine feed. In addition to cereals, co-products of ethanol distillation, brewing, and baking are frequently re-purposed as swine feed. ZEN contamination has been related to severe …

Electron microscopic studies on barley yellow dwarf virus infection in oats
… economic losses worldwide due to damage to cereal crops such as oats, wheat and barley. The virus is transmitted by aphids that inject viral particles into the phloem of the host during the feeding process. BYDVs remain restricted to the phloem tissue and cause cytopathological alterations …

Early Agricultural Communities in Lejja Southeastern Nigeria: An Archaeobotanical Investigation
… of oil palm and tubers but the absence of cereal crops such as pearl millet. These data are further used to argue that the past inhabitants of Lejja consisted of a single community engaged in both smelting and farming who were involved in local production and the exchange of materials and …

AFLP markers linked to Fusarium head blight resistance in Triticum aestivum.
… in Triticum aestivum L. FHB is a disease of cereal crops that results in reduced wheat yields, discoloured, shrivelled kernels, mycotoxin accumulation, and reduced seed and grain quality. Since resistance mechanisms in wheat are complex, often being confounded by environmental effects, and …

Survey of plant density tolerance in U.S. maize germplasm
Global demand for cereal crops like maize is rising at a rapid pace as the world population expands beyond 7 billion people. To meet these needs, productivity (i.e. grain yield) per unit area must be increased. A survey of U.S. maize germplasm was conducted to identify sources of favorable alleles …

Resistance to anthracnose leaf blight in sorghum
Sorghum is one of the most important cereal crops in the world, and most of the production of grain sorghum occurs in the United States. But production of sorghum is limited by economically important diseases which lower the production of sorghum. Sorghum anthracnose may cause from 50 to 86% yield …

The Detection of Vegetation Species in Remote Sensing Imaging
… research in this thesis is on the monitoring of cereal crops, in particular infestation of wheat crops by black grass, a pernicious weed. This is regarded as the major pest for cereal crops, at least in East Anglia, one that causes significant loss of income for farmers. Although annual rather …

Chitosan oligosaccharide: use to control Fusarium head blight and to reduce deoxynivalenol accumulation in wheat grains
Wheat is one of the most important cereal crops worldwide, but several fungal diseases can affect crop yield. Among them, Fusarium head blight (FHB), caused by members of the Fusarium graminearum species complex, is one of the most serious wheat diseases worldwide, resulting in lost ofin yield and …
