Functional Analysis Of Squamosa-Promoter Binding Protein Like 13 In Controlling Flowering Time, Plant Architecture, Grain Size, And Grain Number In Wheat, Ajay Gupta
Electronic Theses and Dissertations
Higher and stable yield is always a major objective of wheat genetic improvement programs. The SQUAMOSA-promoter binding protein-like (SPL) genes constitute a small family of plant-specific transcription factors with diverse functions in plant development and growth and have great potential in improving yield and other major agronomic traits. However, the functional characterization of the SPL gene family in wheat is far behind other cereal crops such as rice. Using phylogenetic analysis, we identified 56 wheat orthologues of rice SPL genes belonging to 19 homoeologous groups. Among these 19 orthologous TaSPL genes, nine harbor the micro RNA 156 recognition element (MRE) …
Sunflower Pollinators In South Dakota: An Evaluation Of Species Composition, Abundance And Influence On Yield, Mackenzie Mattern
Sunflower Pollinators In South Dakota: An Evaluation Of Species Composition, Abundance And Influence On Yield, Mackenzie Mattern
Electronic Theses and Dissertations
In 2017 and 2018, South Dakota was the largest producer of sunflowers, Helianthus annuus L. (Asterales: Asteraceae) in the US, grossing approximately $178 million per year. In South Dakota, both confection and oilseed sunflower cultivars are grown. Despite breeding efforts to increase sunflower's ability to self-pollinate there is evidence that pollinator visitation results in increased sunflower yields. In addition, there is evidence that sunflower pollen is beneficial for pathogen resistance in various bee species, suggesting the importance of a mutualistic relationship between pollinators and sunflowers. In some areas, observed increases in sunflower yield is attributed to the presence of Apis …
The Efficacy Of Allopurinol In Suppressing Hypersensitive-Like Symptoms In Wheat (Triticum Aestivum L.) And In Suppressing Sunflower Rust (Puccinia Helianthi) Symptoms, Thumbiko Walker Gambler Mkandawire
The Efficacy Of Allopurinol In Suppressing Hypersensitive-Like Symptoms In Wheat (Triticum Aestivum L.) And In Suppressing Sunflower Rust (Puccinia Helianthi) Symptoms, Thumbiko Walker Gambler Mkandawire
Electronic Theses and Dissertations
A mutant wheat (Triticum aestivum L.) genotype can constitutively produce hypersensitive-like flecks in the absence of any pathogen. The lesions of the mutant are thought to be the result of Reactive Oxygen Species (ROS), which are similarly implicated in hypersensitive reactions to fungal pathogens. Allopurinol can suppress ROS. Consequently, allopurinol was applied to a wheat lesion mutant to test the hypothesis that the same ROS are involved, regardless of the presence of the pathogen. ‘Ning7840’, a lesion mutant and ‘Alsen’, a related genotype that does not express the mutant phenotype were treated with different concentrations of allopurinol under controlled …
