Discovery: Yeast make plant hormone that speeds infection

In their ongoing studies of how yeast (fungi) can infect a host and cause disease, a research team at the Life Sciences and Bioengineering Center at Worcester Polytechnic Institute (WPI) has made an unexpected discovery. They found that yeast produce a hormone previously known to be made by plants, and that the presence of that hormone in sufficient quantity within the yeast's immediate environment triggers the fungal cells to become more infectious.
