Abscisic Acid Regulation of Branching
Yao, Chi (2013-12-16)Axillary meristem production and activity contribute to the high plasticity of plant development which allows plants to respond to environmental changes. Branches arise from axillary buds that form in the leaf axil. These ... -
Activity and Regulation of AGC Kinases from Physcomitrella patens and Tomato
Nelson, Anna (2012-10-19)The AGC group of protein kinases (named for protein kinases A, G, and C) is found in all eukaryotes studied so far, and its members coordinate essential cellular processes including translation, metabolism, hormone response, ... -
Antagonistic Regulation, Yet Synergistic Defense: Effect of Bergapten and Protease Inhibitor on Development of Cowpea Bruchid Callosobruchus maculatus
Guo, Fengguang; Lei, Jiaxin; Sun, Yucheng; Chi, Yong Hun; Ge, Feng; Patil, Bhimanagouda S.; Koiwa, Hisashi; Zeng, Rensen; Zhu-Salzman, Keyan; Palli, Subba Reddy (PloS One, 2012) -
Anti-inflammatory Properties of Citrus Limonoids and Their Isolation and Characterization
Kim, Jin Hee (2012-02-14)This dissertation investigates the role of limonoids in inflammation to reduce risk of breast cancer and cardiovascular disease. Radical scavenging activity and apoptotic effects of extracts from lemon seeds were investigated ... -
Anti-viral RNAi and its suppression in plants.
Ciomperlik, Jessica J. (2010-01-16)As a defense against viral infection, plants are thought to use RNA-induced silencing complexes (RISCs) to target and cleave viral RNA. To counteract this, some viruses have evolved proteins to inhibit RISC-mediated activity, ... -
Arabidopsis C-Terminal Domain Phosphatase-Like 1 Functions in miRNA Accumulation and DNA Methylation
Jeong, In Sil; Aksoy, Emre; Fukudome, Akihito; Akhter, Salina; Hiraguri, Akihiro; Fukuhara, Toshiyuki; Bahk, Jeong Dong; Koiwa, Hisashi; Park, Sunghun (PloS One, 2013) -
Arabidopsis Thaliana CARBOXYL-TERMINAL DOMAIN PHOSPHATASE-Like1 (CPL1) Mediates Responses to Iron Deficiency and Cadmium Toxicity
Aksoy, Emre (2014-04-24)The expression of genes that control iron (Fe) uptake and distribution (i.e., Fe utilization- related genes) is under a strict regulation. Fe deficiency strongly induces Fe utilization- related gene expression; however, ... -
Biochemical Characterization of Plant Small CTD Phosphatases and Application of CTD Phosphatase Mutant in Hyperaccumulation of Flavonoids in Arabidopsis
Feng, Yue (2011-10-21)In addition to AtCPL1-4, the genome of Arabidopsis thaliana encodes a large number of putative acid phosphatases. The predicted Arabidopsis SCP1-like small phosphatases (SSP) are highly homologous to the catalytic domain ... -
Characterization of PP2A regulatory B subunits in Fusarium verticillioides
Shin, Joonhee (2012-07-16)Fusarium verticillioides is a pathogen of maize causing ear rot and stalk rot. The fungus also produces fumonisins, a group of mycotoxins linked to disorders in animals and humans. A cluster of genes, designated FUM genes, ... -
Diverse functions of the two segmentally duplicated 9-lipoxygenases ZmLOX4 and ZmLOX5 of maize
Park, Yong Soon (2012-07-16)Plant lipoxygenases (LOX) are non-heme iron containing dioxygenases that catalyze the hydroperoxidation of polyunsaturated fatty acids resulting in the synthesis of a large number of functionally diverse oxylipins. Although ... -
The Function of the Lipoxygenase ZmLOX10 in Maize Interactions with Insects and Pathogens
Christensen, Shawn A. (2011-02-22)Lipoxygenase (LOX)-derived oxylipins are known to play critical roles in defense against herbivores and pathogens. The objective of this study was to determine the biochemical, molecular and physiological roles of a specific ... -
Functional and Structural Characterization of Cation/H+ Antiporters
Manohar, Murli (2012-07-16)Inorganic cations play decisive roles in many cellular and physiological processes and are essential components of plant nutrition. Therefore, the uptake of cations and their redistribution must be precisely controlled. ... -
Functions of Arabidopsis C-terminal Domain Phosphatase-like 4 in Global Transcriptional Regulation
Fukudome, Akihito (2017-05-02)Phosphoregulation of the carboxyl-terminal domain of RNA polymerase II largest subunit (pol II-CTD) couples transcription and co-transcriptional modification of nascent RNA. Although the molecular mechanisms have been ... -
Influence of genetic variability on specialty potato functional components and their effect on prostate cancer cell lines
Reddivari, Lavanya (2009-05-15)The influence of genotype (selection), location, and year on antioxidant activity (AOA), total phenolics (TP), total carotenoids (TC), phenolic and carotenoid composition was studied using specialty (colored) potatoes ... -
Molecular and biochemical characterization of three lipoxygenases in maize
Nemchenko, Andriy (2009-06-02)Most plant oxylipins, a large class of diverse oxygenated polyunsaturated fatty acids and their derivatives, are produced through the lipoxygenase (LOX) pathway. Recent progress in dicots has highlighted the biological ... -
