Investigation Of The Role Of Gene Clusters In Terpene Biosynthesis In Sorghum Bicolor, Rebecca Hay
Investigation Of The Role Of Gene Clusters In Terpene Biosynthesis In Sorghum Bicolor, Rebecca Hay
Theses
The staple crop Sorghum bicolor shows potential as a source of secondary metabolite-based biofuels due to its diverse phenotype and chemical profile. S. bicolor produces a variety of high-energy metabolites, including terpenes which are a potential renewable source of fuel additives. Information on the biosynthetic and genetic pathways by which S. bicolor terpenes are produced is limited and these pathways must be better understood before they can be engineered for human applications. Recent work on plant biosynthetic pathways has shown that terpenes can be modified by the products of clustered genes. Identification of biosynthetic gene clusters may accelerate the elucidation …
Roles Of Phospholipases And Ribosomal S6 Kinase In Lipid Remodeling And Growth In Arabidopsis Response To Phosphate Deprivation, Yuan Su
Dissertations
Phosphate (Pi) is one of three macronutrients for plants, which is vital for plant growth and development. Understanding the mechanism by which plants respond and adapt to Pi deficiency not only unveils functions of genes and pathways involved, but also provides potential tools to manipulate crops to better stand Pi stress in low Pi-containing lands. One of the significant metabolic changes in plants under Pi starvation is the membrane lipid remodeling that converts Pi-containing lipids such as phospholipids to Pi-free lipids, such as glycolipids. To elucidate the metabolism and regulation of lipid remodeling, this dissertation characterizes the role of two …
