    Don't spend more than: on two rounds of drinks, and for the doorman. (Even though he's not "technically" your teacher, he's still representing the school as a teacher, and, of course, you are a student.)So for starters, this guy has pretty bad judgment for putting his job and reputation on the line like this.

    Ancient polyploidization predating divergence of the cereals

    Such an event could either double the genome of a single species (autopolyploidy) or combine those of two species (allopolyploidy).Because of functional redundancy, genes are rapidly silenced or lost from the duplicated genomes.Thus, both duplication types and divergence time influence the difference in expression divergence.Using a linear model, we investigated the influence of these two variables and found that the difference in expression divergence between block and dispersed duplicates is attributed largely to their different divergence time.In addition, the difference in expression divergence between tandem and the other two types of duplicates is attributed to both divergence time and duplication type., our results revealed a significant difference in expression divergence between the types of duplicated genes and a significant correlation between expression divergence and synonymous substitution rate.

    In paleopolyploids, gene loss is the main fate of duplicated genes formed by whole-genome duplication (WGD).

    syntenic dotplots) and evolutionary distances (e.g. The images presented here represent our views right now, but are subject to change.

    Events that were previously undetected or missed can suddenly be seen with an improved build of a genome or the sequencing of a fortuitously placed outgroup.

    Our results suggest that paleopolyploidy was widespread and played an important role in the evolution of rice.

    Paleopolyploidy is the result of genome duplications which occurred at least several million years ago (MYA).
