Title: “Circadian Timing Mechanisms in Seasonal Flowering and Plant-Pollinator Interaction” Host: Dawn Nagel Abstract: Many organisms display various seasonal developmental and behavioral changes throughout the year. In my lab, we are interested in elucidating the molecular mechanisms by which organisms use their circadian clock systems to measure and respond to daily and seasonal changes. In [...]

Title: “Stretching the Imagination: Mechanosensitive Channels in Plants” Host: Dawn Nagel & David Nelson Abstract: A long-standing question is how biological systems sense and perceive mechanical signals such as osmotic pressure, gravity, and touch. One well-established molecular mechanism for force sensing is the activation of mechanosensitive (MS) ion channels. The Mechanosensitive channel of Small conductance [...]

Title: “Uncovering a role for phyB-photobody formation in light, temperature, and circadian signaling” Host: Dawn Nagel Abstract: Cellular contents are organized to enable spatial control over signaling pathways, both through the formation of membrane-associated organelles and self-organized biomolecular domains. In plants, the red-light photoreceptors known as phytochromes (phys) form subnuclear, micron-sized foci called photobodies (PB) [...]

Title: “Reprogramming roots cells for arbuscular mycorrhizal symbiosis” Host: David Nelson & Dawn Nagel Abstract: In natural ecosystems, most vascular flowering plants live in symbiosis with arbuscular mycorrhizal (AM) fungi. These mutually beneficial associations develop in the roots, where the fungus colonizes the cortex to obtain carbon from the plant while providing mineral nutrients to [...]

Title: “The endodermis - walking the thin line between protection and exchange” Host: Jaimie Van Norman Abstract: Roots must manage the opposing aims of providing for uptake of nutrients and water from the soil on the one hand and providing protection from potentially harmful microorganism and toxic elements on the other. The endodermis, the main [...]
