Molecular Signatures Of Sexual Communication In The Phlebotomine Sand Flies, Paul V. Hickner, Nataliya Timoshevskaya, Ronald J. Nowling, Frédéric Labbé, Andrew D. Nguyen, Mary Ann Mcdowell, Carolina N. Spiegel, Zainulabeuddin Syed Dec 2020

Molecular Signatures Of Sexual Communication In The Phlebotomine Sand Flies, Paul V. Hickner, Nataliya Timoshevskaya, Ronald J. Nowling, Frédéric Labbé, Andrew D. Nguyen, Mary Ann Mcdowell, Carolina N. Spiegel, Zainulabeuddin Syed

Biology Faculty Publications

Phlebotomine sand flies employ an elaborate system of pheromone communication wherein males produce pheromones that attract other males to leks (thus acting as an aggregation pheromone) and females to the lekking males (sex pheromone). In addition, the type of pheromone produced varies among populations. Despite the numerous studies on sand fly chemical communication, little is known of their chemosensory genome. Chemoreceptors interact with chemicals in an organism’s environment to elicit essential behaviors such as the identification of suitable mates and food sources. Thus, they play important roles during adaptation and speciation. Major chemoreceptor gene families, odorant receptors (ORs), gustatory receptors …


Key Interplay Between The Co-Opted Sorting Nexin-Bar Proteins And Pi3p Phosphoinositide In The Formation Of The Tombusvirus Replicase, Zhike Feng, Nikolay Kovalev, Peter D. Nagy Dec 2020

Key Interplay Between The Co-Opted Sorting Nexin-Bar Proteins And Pi3p Phosphoinositide In The Formation Of The Tombusvirus Replicase, Zhike Feng, Nikolay Kovalev, Peter D. Nagy

Plant Pathology Faculty Publications

Positive-strand RNA viruses replicate in host cells by forming large viral replication organelles, which harbor numerous membrane-bound viral replicase complexes (VRCs). In spite of its essential role in viral replication, the biogenesis of the VRCs is not fully understood. The authors identified critical roles of cellular membrane-shaping proteins and PI(3)P (phosphatidylinositol 3-phosphate) phosphoinositide, a minor lipid with key functions in endosomal vesicle trafficking and autophagosome biogenesis, in VRC formation for tomato bushy stunt virus (TBSV). The authors show that TBSV co-opts the endosomal SNX-BAR (sorting nexin with Bin/Amphiphysin/Rvs- BAR domain) proteins, which bind to PI(3)P and have membrane-reshaping function during …


Diverse And Complex Muscle Spindle Afferent Firing Properties Emerge From Multiscale Muscle Mechanics, Kyle P. Blum, Kenneth S. Campbell, Brian C. Horslen, Paul Nardelli, Stephen N. Housley, Timothy C. Cope, Lena H. Ting Dec 2020

Diverse And Complex Muscle Spindle Afferent Firing Properties Emerge From Multiscale Muscle Mechanics, Kyle P. Blum, Kenneth S. Campbell, Brian C. Horslen, Paul Nardelli, Stephen N. Housley, Timothy C. Cope, Lena H. Ting

Physiology Faculty Publications

Despite decades of research, we lack a mechanistic framework capable of predicting how movement-related signals are transformed into the diversity of muscle spindle afferent firing patterns observed experimentally, particularly in naturalistic behaviors. Here, a biophysical model demonstrates that well-known firing characteristics of mammalian muscle spindle Ia afferents – including movement history dependence, and nonlinear scaling with muscle stretch velocity – emerge from first principles of muscle contractile mechanics. Further, mechanical interactions of the muscle spindle with muscle-tendon dynamics reveal how motor commands to the muscle (alpha drive) versus muscle spindle (gamma drive) can cause highly variable and complex activity during …
