Job Opening. Faculty Position in Plant Evolutionary Biology at University of California, Davis in the Department of Evolution and Ecology (EVE, my home department). More detail here. recruit.ucdavis.edu/JPF07777
POSITION DESCRIPTION

The College of Biological Sciences at the University of California, Davis invites applications and nominations for a 9-month, tenure-track position in the Department of Evolution and Ecology at the ASSISTANT PROFESSOR level. The Department of Evolution and Ecology is seeking a plant evolutionary biologist with interests in the evolution of plants at any taxonomic, geographic, organizational, or evolutionary scale. Candidates must have a Ph.D. (or equivalent) in the biological sciences, evolutionary biology, ecology, genetics, or a related field, and will be expected to complement and build upon existing faculty strengths in the Department of Evolution and Ecology and across UC Davis.

We welcome applicants working on any group of plants and using empirical, computational, experimental, and/or theoretical approaches. Possible areas of study are broad, and include macroevolutionary research on plant diversification, trait evolution in a phylogenetic context, major evolutionary innovations, comparative genomics, and evolutionary developmental biology, as well as research focusing at or below the species level including population biology, quantitative genetics, adaptive evolution, speciation, biogeography, and the evolution of life histories or species interactions.

A few warm days stimulate early-flowering trees. This hazel alder, Alnus serrulata, has opened long yellow catkins - male inflorescences - to release pollen to the wind. The red female inflorescence opens a bit later on an individual tree to minimize self-pollination. Are you seeing tree flowers?

What DNA variants alter transcription factor (TF) binding affinity? Here, we describe a new workflow baal-nf. We used it to trawl through 6017 ChIP-Seq data sets for 558 TFs and 46 genotyped cell lines, finding 298,783 allele-specific binding sites (ASBs). www.biorxiv.org/content/10.1... 1/2
Description of image: Workflow for identifying high-quality ASBs through baal-nf. ChIP-sequencing data from genotyped cell lines is used to infer ASBs at heterozygous SNPs using BaalChIP. Identified ASBs are further characterized by mapping them to JASPAR and NoPeak motifs for a given TF. High-quality ASBs show concordance in the corrected allelic ratio and motif score difference.
