Characterization of a major cluster of genes involved in nitrogen fixation and another required for indole-3-acetic acid biosynthesis in the sugarcane endophyte, Acetobacter diazotrophicus
… A plant growth promoting substance like indole-3-acetic acid (IAA) may represent the latter effect that accounts for improved plant growth. My first project was to characterize the genes responsible for nitrogen fixation, and determine their regulation. In summary, I have isolated, …

Azido Auxins: Synthesis and Use as Photoaffinity Labeling Agents
… in plants was developed. Three analogs of indole-3-acetic acid, a natural plant hormone of the class called auxins, were synthesized by Dr. Lee Melhado to be used as photoaffinity labeling agents in plants. The analogs, 4-, 5-, and 6-azidoindole-3-acetic acid, were prepared in seven steps …

Characterization of Arabidopsis thaliana mutants defetive in auxin metabolism
… The most abundant naturally occurring auxin is indole-3-acetic acid (IAA). IAA is found in plants both as the free acid and in conjugated forms. It is believed that the balance between IAA biosynthesis, metabolism, and transport determines the actual levels of IAA in a cell at any given time, …

Use of Bacillus subtilis starter cultures during red sorghum malting
… red sorghum enzymes are elucidated. Gibberellic acid and abscisic acid diffusion and cross-talk as factors affecting the synthesis of red sorghum malt α- and β-amylase activities are also discussed. The production of 3-indole acetic acid (IAA) by B. subtilis S499 was also a focus in this study …

Characterization of a carbon source-dependent, phytohormone-responsive, free methionine-(R)-sulfoxide reductase from Komagataeibacter hansenii
… ATCC 23769 is a gram negative, non-pathogenic, acetic acid bacterium, best known for its ability to produce bacterial cellulose (BC). BC, an extracellular polysaccharide, is an important component of biofilms as it promotes anchoring to surfaces for nutrient acquisition and protection from …

THERMOSTABLE EXOSHELLS AS TOOLS FOR RECOMBINANT PROTEIN EXPRESSION AND IN VIVO DELIVERY
… and that the internalized enzymes can hydrolyze indole-3-acetic acid (IAA) into reactive intermediates. tES specifically mediates endocytotic uptake of the enzyme into MDA-MB-231 and systemic treatment with IAA in the presence of locally administered tES(+)/tES-HRP results in complete tumor …

Examination of auxin transport and root development in the scd1-1 mutant in Arabidopsis thaliana
The hormone indole-3-acetic acid (IAA) is transported unidirectionally in plant cells via asymmetrically localized carrier proteins. This polarity is believed to be established and maintained by vesicular delivery and endosomal cycling of these proteins. The SCD1 (stomatal cytokinesis defective) …

KINETIC ANALYSIS OF AUXIN-INDUCED TRANSCRIPTION FACTOR NETWORKS CONTROLLING LATERAL ROOT DEVELOPMENT IN ARABIDOPSIS THALIANA
… An 8-timepoint microarray of roots treated with indole-3-acetic acid (IAA), the major form of auxin, was utilized to identify the transcriptome wide kinetics of auxin response. This microarray allowed identification of novel auxin responsive genes beyond those found in four other auxin microarray …

Functional genomics through metabolite profiling and gene expression analysis in Arabidopsis thaliana
… convert plant hormones, like jasmonic acid, indole-3-acetic acid, salicylic acid, gibberellins, and other plant constituents into methyl esters, thereby regulating the biological activity of these molecules and, consequently, myriad important physiological processes. Our research aims …

Understanding and Engineering Chemically Activated Ubiquitin Ligases for High-throughput Detection, Quantification, and Control of Molecules in Yeast
… and humans. Certain fungi produce auxin or indole-3-acetic acid (IAA), a crucial plant growth hormone that influences various aspects of plant growth and defense mechanisms. Conversely, pathogenic fungi can produce auxin and manipulate auxin signaling in their host plant to promote fungal …

Symbiotic Associations and Pathogenic Potential of Vibrios In the North Inlet Estuary
… rhizoplanes; to synthesize the phytohormone indole-3 acetic acid via the indole-3-acetamide pathway was elucidated and quantified. An extensive study of the density and biogeography of Vibrionaceae in sediment, burrow and water microniches was conducted and a collection of 186 presumptive …

Functional characterisation of NIC2, a member of the MATE family from Arabidopsis thaliana (L.) Heynh.
… chloride (TMACl) and a toxic analogue of indole-3-acetic acid, 5-fluoro-indole-acetic acid (F-IAA). Therefore, NIC2 may be able to transport a broad range of drug and toxic compounds. In wild-type yeast the expression of NIC2 increased the tolerance towards lithium and sodium, but not …

In Vitro Regeneration and Genetic Transformation of Sesbania Drummondii: A Medicinally and Environmentally Important Plant
… of benzyladenine (8.8 and 11.1 /JM) and either indole-3-butyric acid (0.24 - 2.46 //M) or indole-3-acetic acid (0.28 - 2.85 //M) produced fewer shoots. Callus when subcultured on 2.2 /LihA thidiazuron containing medium resulted in its mass proliferation of calli having numerous embryoid-like …
