Have you ever noticed when you are hungry and looking for something to eat, you can smell the freshly salted fries of McDonalds before seeing the golden arches? That is because our sense of smell, olfaction, is intimately linked with...
Large-scale cytogenetic mapping in maize has been a major challenge primarily due to fact that the maize genome has a low gene density and an abundance of repetitive sequence elements. Using a unique combination of biological and genome...
To improve the design of prostheses surfaces, our research group investigates how biocompatible polyelectrolyte multilayers (PEMUs) can be constructed to serve as coatings for biomedical implants, providing a versatile, inexpensive, and...
Stomata, each delimited by a pair of guard cells, are crucial for gas exchange in terrestrial plants. Guard-cell apoplastic sucrose concentration was proposed to be a signal that integrates the information from bulk-leaf apoplastic...
The metabolic state of an organism and their sense of olfaction are closely interrelated. There is significant evidence that olfactory signals can modulate multiple metabolic parameters and, in turn, that metabolically relevant signals...
In order to understand the molecular basis of meiotic telomere behavior, we have set out to identify genes that encode proteins with telomere repeat DNA-binding activity in maize (Zea mays L.), a model organism system. Using a...
Stomata close when plants are exposed to elevated CO2 concentration and they open when plants are exposed to low CO2 concentration. However, molecular elements of the signal transduction network involved in CO2 sensing have not been...
We previously discovered a large titin-like protein - c-titin - in chicken epithelial brush border and human blood platelet extracts that binds alpha-actinin and organizes arrays of myosin II bipolar filaments in vitro. RT-PCR analysis...
Drosophila melanogasterfemale fruit flies possess a pair of ovaries in which many egg chambers are produced, each containing an oocyte that houses the haploid female gamete. In the process of oogenesis, the multi-cellular egg chamber is...
ABA Contents in the Guard-Cell Symplast and Guard-Cell Apoplast Are Not Correlated with Stomatal Aperture Size under Three Conditions of Water Sufficiency
Guard cells respond to environmental stimuli by opening and closing stomata, which balance CO2 uptake and water conservation. Stomatal closure under water deficiency and the involvement of abscisic acid (ABA) in this response are well...
A field survey of the southeastern United States showed that Pheidole obscurithorax Naves, an ant introduced from South America, inhabits a 50-mile-wide band along the coast between Mobile, Alabama, and Tallahassee, Florida, and is...
Conditioned taste aversion (CTA), a form of associative learning, is characterized by behavioral changes after the pairing of a novel palatable taste such as sucrose with a toxin (such as lithium chloride), resulting in aversive...
Biocompatible coatings are often used to improve fixation between implants and tissues. Polyelectrolyte multilayer (PEMU) coatings built layer by layer with alternating pairs of polyelectrolytes can be tuned to improve cell interactions...
Tree nuts are a widely consumed food and include walnut, cashew, almond, hazelnut, pistachio, pecan, chestnut, macadamia, and Brazil nut. Although enjoyed safely by most individuals, allergic reactions are common and ~0.6% of the US...
The structure and function of the eye is conserved across vertebrates. Mutagenesis screens of zebrafish have led to the discovery of many genes essential for retinal development and function. In one such screen, a recessive allele on the...
Many of the genes that regulate eye and retinal development have been identified based upon mutant analysis in animal models or human diseases. Taking advantage of the mosaic organization of the photoreceptor in zebrafish our laboratory...
