Genetics: Analysis of Genes and Genomes: Keyword Hot Links for chapter 13

A highly effective way to appreciate the complex, interactive hierarchy of gene activation and repression in Drosophila development is to explore the interactive flyat this keyword site. Created by Tom Brody and Judith Brody, this resource enables you to learn more about the stages and time course of developmental processes and much more about the genes that are involved, all richly illustrated with drawings and photographs.

The nematode worm C. elegans was the first multicellular organism whose complete developmental program of cell lineages was described, and also the first multicellular organism whose genome was completely sequenced. You can explore the lineage diagram at this keyword site and the worm proteome at these keyword sites. The challenge for developmental genetics is to be able to understand in detail the relationships between the constituents of the proteome and the patterns in the lineage diagram.

Check out this site to learn about other genes involved in flower development in Arabodopsis and to see picture of the mutant phenotypes. You can also learn more about the family of over 30 Arabidopsis genes known as MADS-box genes, which encode transcription factors, many of which are important in flower development.
