Past PMB Seminars
Sentinels and foot soldiers in plant immunity
I will talk about ongoing projects in my lab for a better understanding of plant surveillance system and defense metabolites. In the first half I will discuss how a nucleotide-binding, leucine-rich repeat receptor (NLR) called ZAR1 senses bacterial virulence activity to activate immunity. In the second half I will discuss how plant defense metabolites protect plants by specifically targeting a...
Modeling microbial influences on animal growth and development
Microbes have been adjacent to and integral in animal evolution. Invertebrate models facilitate the collection of high-resolution data on the impact of gut microbiomes on host growth and development. We will present some of our work in live model development and deployment.
Mechanisms and evolution of adaptive mutation bias in plants
Mutations are the ultimate source of all genetic variation. In this seminar, we explore mechanisms underlying the evolution of adaptive mutation rate heterogeneity within plant genomes. We discuss what emerging discoveries mean for ideas of mutational randomness and the potential for mutation bias to shape the origins of plant diversity.
Growth and adaptation in diverse alphaproteobacteria
My laboratory investigates mechanisms of bacterial growth, division, cellular organization, and adaptation primarily using the tools of cell biology, biochemistry, and genetics. We leverage two alphaproteobacterial model species with distinct lifestyles to probe conserved and adaptive mechanisms underlying fundamental processes in bacterial cell biology: the free-living oligotroph Caulobacter...
Insights and Applications Deriving from Interbacterial Antagonism
Our lab studies the mechanisms and consequences of antagonism between bacteria. While much work has focused on toxins that mediate these interactions, in this seminar, I will be discuss recent work from our lab describing defense factors against antagonism. I will also discuss some recent efforts by our laboratory to harness the unique biology of antagonistic mechanisms for the development of...
