Research in the Rosenzweig lab is aimed at illuminating the evolution of complex traits that augment biodiversity, control cell lifespan and drive major transitions in the history of life. Our goals are to understand how changes in genome architecture alter global patterns of gene expression, whether such changes explain the physiology and behavior of novel genotypes, and the extent to which adaptation is shaped by trade-offs and constraints. Because all major evolutionary transitions require cooperative behavior, we are especially keen to discover genetic changes that promote this trait. Our approach to these goals is experimental evolutionary genomics using as models the bacteria Escherichia coli and Bdellovibrio bacteriovorus, the Bakers yeast Saccharomyces cerevisiae and the unicellular alga, Chlamydomonas reinhardtii. With new and continuing funding from NASA, NIH and the Templeton Foundation we are addressing six fundamental questions.
(1) How does a community arise from a single clone? (2) How did the eukaryotic cell, specifically the cell that had a mitochondrion, come to be? (3) How does multicellularity arise? (4) What is the true rate of beneficial mutation – and how pervasive are the pleiotropic effects of those mutations? (5) How might severe stress favor the emergence of new species. (6)What controls the lifespan of a eukaryotic cell?
NIH-NHGRI PI: G Sherlock (Stanford), co-PI: F Rosenzweig Project Title: Molecular Characterization of Adaptive Evolution Project Description: The aim of this research is to assess how populations explore adaptive landscapes, whether adaptive mutations are beneficial in environments other than those in which they evolved, and whether early-arising mutations constrain subsequent evolutionary trajectories.
NASA Exobiology PI: F Rosenzweig, co-PI: G Sherlock (Stanford) Project Title: E unibus plurum: Ecological and Genomic Constraints on the Evolution of Complexity. Project Description: The goal of this research is to systematically investigate the roles that genotype and resource type play in determining the evolution of metabolic interdependence in asexual microbes.
NIH-GMS PI: Sherlock (Stanford), co-PI: Rosenzweig Project Title: Systematic Molecular Analysis of Antagonistic Pleiotropy Project Description: The objectives of this project are to use molecular lineage tracking to discover the spectrum of newly arising beneficial mutations in experimentally evolving yeast populations, to determine the degree of antagonistic pleiotropy (AP) exerted by each, and for a subset of AP gene, the evolutionary paths that lead to resolution of, or adaptive escape from AP.
NASA Exobiology PI: Rosenzweig, co-PI: G Sherlock (Stanford) Science PI: E Kroll (Montana) Project Title: Genomic Responses to Stress: Implications for Adaptation and the Origin of New Species Project Description: The goal of this project is to follow up on our recently published work suggesting that severe stress in the form of prolonged starvation specifically elevates rates of genomic rearrangement, creating new variants, some of which are adaptively favored and whose novel genome structures favor reproductive isolation in sympatry.
Templeton Foundation PI: M Travisano (MInnesota), co-PI: F Rosenzweig Templeton Postodoc Matthew Herron (Montana) Project Title: Experimental Evolution of Multicellularity Project Description: In this project we seek to seek the answer to this question: why is the evolution of multicellularity repeatable. In so doing we will address three other questions: How readily does multicellularity evolve? What is the tempo and mode in the first steps to multicellularity? Does evolutionary ancestry substantially impact multicellular adaptability?
NASA Postdoctoral Program (NPP) NPP Fellow: M Kinnersley Sponsor: F Rosenzweig Project Title: Co-Evolution of Escherichia coli and its parasite Bdellovibrio bacteriovorus: An experimental model for Eukaryogenesis Project Description: The goal of this project is to generate an experimental model in which to study the early steps in the origin of the eukaryotic cell.
