The chromatin landscape of barley: gene expression, evolution and epigenetics
… component with a genomic investigation of gene expression, diversity and evolution. Chromatin environments were also explored in the LR and high recombining (HR) regions by surveying the genic and genomic distributions of nine histone modifications.<br/><br/>Firstly, regions of HR and LR were …

Developmental and Expression Evolution in C3 and C4 Atriplex and their Hybrids
… C3 x C4 Atriplex F1 hybrids and allele-specific expression analysis to investigate the role of cis- and trans-regulatory effects on gene expression divergence. The majority (~80%) of expression divergence between C3 and C4 species arose from cis-only regulatory divergence, suggesting that …

Sex Differences and the Evolution of Gene Expression
… are essential byproducts and drivers of evolution in sexually reproducing species. Knowing how sex differences arise and how they influence evolution is central to our understanding of evolution. Although many facets of sex differences have been explored, many remain unknown. Here I focus …

On the nature and measurement of variational bias: a developmental perspective
… testing its implications in shaping phenotypic evolution. Specifically, I answer three questions: (1) How does the central conponent of nonlinear genotype-to-phentype map --- transcriptional regulation --- bias the analyses of gene-gene interactions? (2) How to disentangle the contribution of …

Bacterial genes and genome dynamics in the environment
… adaptation by bacteria via gene content or gene expression evolution. Associating genes' usage and evolution to adaptation in various environments is a cornerstone of microbiology. New technologies and approaches have revolutionized this pursuit, and I begin by describing the computational …

Understanding Evolution of Gene Expression by Comparative Analysis
<p>During the course of evolution, phenotypic adaptations can arise from changes in both gene function and gene expression. Evolution of gene function is well-documented in comparative genomics through the study of protein and DNA sequences. But the evolution of gene expression is not …

The evolution of gene regulatory landscapes in mammalian tissues
Gene regulatory landscapes are highly complex and evolutionarily unstable. Understanding how genetic and regulatory variations affect gene expression evolution is paramount to gaining insight into phenotypic divergence across species. Although gene expression programs are broadly maintained during …

FUNCTIONAL STATISTICAL LEARNING METHODS APPLIED TO HUMAN EMOTION RECOGNITION FROM FACIAL VIDEOS
… behavior has inspired a profound focus on the evolution of facial expressions and the recognition of corresponding emotions. By harnessing functional statistical learning methods, we develop a comprehensive methodology that capitalizes on the dynamic properties of continuity and evolvability …
