Regulation Of Local Auxin Metabolism During Soybean Nodule Development, Suresh Damodaran
Regulation Of Local Auxin Metabolism During Soybean Nodule Development, Suresh Damodaran
Electronic Theses and Dissertations
Legume-rhizobia symbiosis leads to the development of secondary root organs called nodules. Rhizobia bacteria housed inside nodules assimilate atmospheric nitrogen and convert them into plant usable forms thereby reducing the need for fertilizer application in crop legumes like soybean. Nodule development is a coordinated process orchestrated by multiple plant hormones. In soybean, the auxin responsive gene expression was detected in nodule primordia and in the periphery of mature nodules, primarily in nodule vasculature. Auxin hypersensitivity reduces nodule formation in soybean and also polar auxin transport inhibition at the site of nodule development is not crucial for determinate nodule formation. Therefore, …
Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez
Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez
Electronic Theses and Dissertations
Phytochemicals such as tannins included in dairy cow nutritional programs, as a natural feed additive, promise to improve rumen bypass protein and consequently reduce the feeding cost by decreasing the amount of CP needed in the ration. Additionally, if tannins are fed along with high quality protein sources, this could improve the AA profile reaching the small intestine and potentially improving health and performance of dairy cows. The black pepper, specifically its alkaloid piperine, is a nontoxic, natural dietary compound with a broad range of physiological activity. Lactating dairy cows ingesting these phytochemicals (tannin extracts and black pepper) will potentially …
