In Memoriam Clarence A. (Bud) Ryan

Bud Ryan left us on October 7th, 2007. Hissudden passing away is felt deeply by his family and friends. Bud has left us with a flourishing field of research but we must now continue along this road without him. Throughout his long career Bud gave the community many startling insights into nature. One of the first milestones in the long and unerring path to reveal the invisible secrets of the plant defense mechanism was the discovery,published in 1972, of wound-inducible proteinase inhibitors in potato. Much of Bud’s career was spent finding out how these proteins functioned in defense, how they were made, and how their genes were regulated. Constantly incorporating new ideas and technologies, Bud and his collaborators brought to light the first peptide hormone in plants (systemin) and found that jasmonates regulate proteinaseinhibitor gene expression. These and other achievements initiated much if not most of the ongoing work in trying to understand the wound response in plants. All those who joined him in this endeavour were touched by his vision, his modesty, his strong sense of humour, and, above all, by his friendship. I personally feel the void he has left and know that this feeling is shared by my colleagues. Lausanne,Switzerland, October 18th, 2007 Edward E. Farmer
