The genome of black cottonwood, Populus trichocarpa (Torr. & Gray).

We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction of the genome. More than 45,000 putative protein-coding genes were identified. Analysis of the assembled genome revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. A second, older duplication event is indistinguishably coincident with the divergence of the Populus and Arabidopsis lineages. Nucleotide substitution, tandem gene duplication, and gross chromosomal rearrangement appear to proceed substantially more slowly in Populus than in Arabidopsis. Populus has more protein-coding genes than Arabidopsis, ranging on average from 1.4 to 1.6 putative Populus homologs for each Arabidopsis gene. However, the relative frequency of protein domains in the two genomes is similar. Overrepresented exceptions in Populus include genes associated with lignocellulosic wall biosynthesis, meristem development, disease resistance, and metabolite transport.

Considerations on the dynamics of fraud and shoplifting in adult female offenders.

This paper compares two groups of adult female offenders involved in shoplifting and fraudulent behaviour. Twenty women were studied whose first offenses occurred in their mid-life period. The major findings conclude that an unresolved mourning or loss in the context of high stress and depression is one of the commonalities in the two groups. Another commonality is that a defined classical role for these women is conflictual and the relationship established with their spouses is a repetition of their relationship with their father. The authors suggest that these types of acting out in general are a depressive equivalent, and a larger sample could duplicate the findings and collect more precise data about the nature of the relationship in the family of origin to help these women feel better in their social role.
