Hyped‐up for Hox in Hyderabad

Abstract

The EMBO Workshop on Upstream and Downstream of Hox Genes took place in Hyderabad, India, between 14 and 17 December 2005, and was organized by R. Mishra and F. Karch. ![][1] For many years, EMBO workshops dealing with new insights into the regulation and function of Hox genes have been held in Switzerland. However, last year, the EMBO World Programme, together with the Centre for Cellular and Molecular Biology (CCMB), held a workshop entitled Upstream and Downstream of Hox Genes in the CCMB's hometown of Hyderabad, India. Imagine beautiful gardens full of butterflies and palm trees, a delightful guest house neighbouring a state‐of‐the‐art research centre, all in a peaceful oasis surrounded by a pulsating and crowded Indian city. The question at the beginning of the meeting was whether the talks and discussions would match the stunning environment; it was answered rapidly and affirmatively. Hox genes have had an illustrious and curious history. Perhaps one of the most famous images in biology from the past century is the four‐winged mutant of the fruit fly Drosophila melanogaster caused by mutations in the Hox gene Ultrabithorax ( Ubx ). This fascinating mutant fly, discovered and characterized by Edward B. Lewis, has motivated many investigators to join the field to understand how these genes are responsible for such complex changes in morphology. Another highlight of Hox history was Matthew Scott's, William McGinnis's and Walter Gehring's discovery of the homeodomain—a 60‐amino‐acid DNA‐binding motif now known to be a key domain in hundreds of genes throughout the animal, fungal and plant kingdoms. Although a lot has been learned through experiments stemming from these important discoveries, there are still many open questions. Among the questions being debated in the field and at the meeting are: How is the regulation of the Hox genes initiated and maintained? How do Hox proteins … [1]: /embed/graphic-1.gif
