Libo Shan: Mobilization of molecular defense by phytocytokine-receptor signaling
Plant genomes encode over thousands of small peptides, whose functions remain mostly enigmatic. Nevertheless, some secreted peptides have been implicated to be important players in regulating diverse plant physiological processes, including cell growth, development, reproduction, immunity, and abiotic stress adaptations. Plant small peptides with immunomodulatory functions are also known as...
Sensory regulation of bacterial collective behaviors
Bacterial responses to self-generated and exogenous stimuli influence their survival, persistence in particular niches, and transitions between individual such as swimming and collective behaviors such as development of structured communities encased in extracellular matrix called biofilms. Our overarching research goal is to combine bacterial genetics, molecular biology, biochemistry,...
Enrique Rojas: The Evolutionary Mechanics of Microbial Morphogenesis
I will describe how we discovered a universal constraint on the shapes of tip-growing fungi, protists, plant, and bacterial cells that is imposed by the convergent mechanical mechanism of their cell growth. Interestingly, this constraint emerges as a "tipping-point" instability (think Malcom Gladwell) in the fitness landscape of tip-growing cells that separates fast-growing from slow-growing...
