Microfluidic‐Assisted Evolution of a Robust NAD+‐Dependent Enzyme with Improved Isobutanol Tolerance at Elevated Temperatures

open access: yesChemSusChem, EarlyView.
Utilizing the power of the absorbance‐activated droplet sorter, a key enzyme for a cell‐free multienzymatic cascade for sustainable isobutanol biosynthesis is optimized for improved thermostability and isobutanol tolerance required for efficient cascade performance.

Epistasis detectably alters correlations between genomic sites in a narrow parameter window.

open access: yesPLoS ONE, 2019
Different genomic sites evolve inter-dependently due to the combined action of epistasis, defined as a non-multiplicative contribution of alleles at different loci to genome fitness, and the physical linkage of different loci in genome.

Characterizing season‐long floral trajectories in cotton with low‐altitude remote sensing and deep learning

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plant breeding is a critical tool for increasing the productivity, climate resilience, and sustainability of agriculture, but current phenotyping methods are a bottleneck due to the amount of human labor involved. Here, we demonstrate high‐throughput phenotyping with an unmanned aerial vehicle (UAV) to analyze the season‐long flowering pattern in ...

Long-Range Epistasis Mediated by Structural Change in a Model of Ligand Binding Proteins. [PDF]

open access: yesPLoS ONE, 2016
Recent analyses of amino acid mutations in proteins reveal that mutations at many pairs of sites are epistatic-i.e., their effects on fitness are non-additive-the combined effect of two mutations being significantly larger or smaller than the sum of ...

Higher-order epistasis and phenotypic prediction

open access: yesbioRxiv, 2020
Contemporary high-throughput mutagenesis experiments are providing an increasingly detailed view of the complex patterns of genetic interaction that occur between multiple mutations within a single protein or regulatory element.

Supervised Learning of Protein Melting Temperature: Cross‐Species vs. Species‐Specific Prediction

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Protein melting temperatures are important proxies for stability, and frequently probed in protein engineering campaigns, for instance for enzyme discovery and protein optimization. With the emergence of large datasets of melting temperatures for diverse natural proteins, it has become possible to train models to predict this quantity, and the

On Epistasis

open access: yesCOMPUTING AND INFORMATICS, 1995
In this note, we compare two previously introduced notions  of epistasis and prove that they are essentially equivalent.

HAMILTONIAN MODEL FOR MULTIDIMENSIONAL EPISTASIS [PDF]

open access: yesInternational Journal of Modern Physics C, 2003
We propose and solve a Hamiltonian model for multidimensional epistatic interactions between beneficial mutations. The model gives rise to either a phase transition between two equilibrium states, without any coexistence, or exhibits a state where hybrid species coexist, with gradual passage from one wild type to another. The transition takes place as

Recent Statistical Innovations in Human Genetics

open access: yesAnnals of Human Genetics, EarlyView.
ABSTRACT We review three areas of human genetics that have been developed in the past few decades, in which statistical innovation has made a crucial contribution with recent important advances and the potential for further rapid progress. The first topic is the development of mathematical models for the genealogy underlying samples of genome‐wide ...

Strong Selection Significantly Increases Epistatic Interactions in the Long-Term Evolution of a Protein. [PDF]

open access: yesPLoS Genetics, 2016
Epistatic interactions between residues determine a protein's adaptability and shape its evolutionary trajectory. When a protein experiences a changed environment, it is under strong selection to find a peak in the new fitness landscape.
