Title: “Milk of the Poppy:  More Than Meets the Eye” Host: Dr. Yanran Li Abstract: Opium poppy remains to sole commercial source of many pharmaceutical alkaloids including morphine, codeine and derivatives of thebaine, such as oxycodone and naloxone. Natural opiate biosynthesis involves two cell types – sieve elements of the phloem and adjacent laticifers. The [...]

Title: “Genome Editing in Grass Species” Host: Dr. Julia Bailey-Serres Abstract: Programmable nucleases (e.g., CRISPR RNA guided Cas nucleases) have been successfully engineered to induce site-specific mutations (deletions, insertions, and substitutions) at genomic loci in grass plants such as rice, maize, wheat, sorghum, etc. The genome editing tools have significantly advance our basic understanding of [...]

Title: “From networks to switches: systems approaches to unravel the control of biological processes necessary for plant life” Host: Julia Bailey-Serres Abstract: Nitrogen is essential for plant growth. Insufficient nitrogen leads to decreased agricultural yield while nitrogen application from fertilizers results in increased plant productivity but can have a negative impact on the environment. Changes [...]

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 [...]
