The genetics and genomics of the silkworm, bombyx mori*

Abstract: We review progress in applying molecular genetic and genomic technologies to studies in the domesticated silkworm, Bombyx mori, highlighting its use as a model for Lepidoptera, and in sericulture and biotechnology. Dense molecular linkage maps are being integrated with classical linkage maps for positional cloning and marker-assisted selection. Classical mutations have been identified by a candidate gene approach. Cytogenetic and sequence analyses show that the W chromosome is composed largely of nested full-length long terminal repeat retrotransposons. Z-chromosome-linked sequences show a lack of dosage compensation. The downstream sex differentiation mechanism has been studied via the silkworm homolog of doublesex. Expressed sequence tagged databases have been used to discover Lepidoptera-specific genes, provide evidence for horizontal gene transfer, and construct microarrays. Physical maps using large-fragment bacterial artificial chromosome libraries have been constructed, and whole-genome shotgun sequencing is underway. Germline transformation and transient expression systems are well established and available for functional studies, high-level protein expression, and gene silencing via RNA interference.

Cognitive and Behavioral Distancing from the Poor.

Abstract: The author argues that distancing is the dominant response to poor people on the part of those who are not poor and that distancing, separation, exclusion, and devaluing operationally define discrimination. Such responses, together with stereotypes and prejudice, define classism. The article focuses on classism in the United States. Classism is examined in the context of theoretical propositions about the moral exclusion of stigmatized others and is illustrated by cognitive distancing, institutional distancing (in education, housing, health care, legal assistance, politics, and public policy), and interpersonal distancing. The adoption of the Resolution on Poverty and Socioeconomic Status by the American Psychological Association Council of Representatives in August 2000 is cited as an important step in the direction of eliminating the invisibility of low-income persons in psychological research and theory.
