The Cost of Gene Expression Underlies a Fitness Trade-Off in Yeast
(National Academy of Sciences, 2009)
Natural selection optimizes an organism's genotype within the context of its environment. Adaptations to one environment can decrease fitness in another, revealing evolutionary trade-offs. Here, we show that the cost of ...
High-Resolution Mutation Mapping Reveals Parallel Experimental Evolution in Yeast
(Public Library of Science, 2006)
Understanding the genetic basis of evolutionary adaptation is limited by our ability to efficiently identify the genomic locations of adaptive mutations. Here we describe a method that can quickly and precisely map the ...
Leaf palmate venation and vascular redundancy confer tolerance of hydraulic disruption
(Proceedings of the National Academy of Sciences, 2008)
Leaf venation is a showcase of plant diversity, ranging from the grid-like network in grasses, to a wide variety of dendritic systems in other angiosperms. A principal function of the venation is to deliver water; however, ...
