Finding a mate is essential for reproduction\, but is challenging in a complex and changing world. Urbanization is an example of drastic environmental change\, with animals needing to deal with interference from sensory pollutants\, such as artificial light at night and anthropogenic noise. On a smaller scale\, animals can interact with different conspecifics that potentially vary greatly in their phenotypes. Feedback from and adjustments to conspecifics can shape sexual communication. Focusing on urban túngara frogs and vibrationally duetting treehoppers\, my research explores how animals adjust their sexual communication to environmental changes. \nThe presentation will begin at 3:00 PM in Lapham Hall N101\, preceded by an informal reception from 2:45 – 3:00PM.

Engineering the pyrenoid into crops has great potential to increase yields. The pyrenoid enhances photosynthesis by clustering the CO2-fixing enzyme Rubisco into a dynamic liquid-like condensate and supplying it with concentrated CO2. A molecular understanding of pyrenoid biogenesis and regulation will facilitate the engineering of the pyrenoid and shed light on how the pyrenoid plays such an important role in the global carbon cycle. However\, both the structural basis of the pyrenoid condensate and how its phase separation is regulated were unknown. In my talk\, I will share our structural characterization of how the pyrenoid condensate is formed by a linker protein that clusters multiple Rubisco holoenzymes\, which reveals a critical motif that mediates the assembly of the pyrenoid’s three sub-compartments. Furthermore\, I will discuss our discovery and characterization of a protein kinase that regulates the size and number of the pyrenoid condensate through disrupting phase separation. Our findings advance the structural and regulatory understanding of the pyrenoid\, paving the way for its engineering into crops. More broadly\, our work makes the pyrenoid a powerful model for studying biological and biophysical mechanisms of biomolecular condensates in cell biology. \nThe presentation will begin at 3:00 PM in Lapham Hall N101\, preceded by an informal reception from 2:45 – 3:00PM.
