Research Interests
Professor Bishop's research interests are in molecular evolution
and plant population biology. Projects in molecular evolution combine
comparative sequence analyses and with enzyme structural information
to gain insight into plant-pathogen arms races at the molecular
level. We have analyzed several cell-wall degrading enzymes deployed
by invading pathogens (e.g. polyglacturonase) or as defenses by
plants (chitinase, b-1,3-endoglucanase), along with corresponding
inhibitors. Currently we are expanding these studies to other PR
proteins, and investingating differentiation of chitinase and endolgucanase
gene families. A second project examines primary successional processes
at Mount St. Helens. We use experimental, observational, and modelling
to document and spatially structured trophic interactions and their
effect on lupine colonization, and disentangle the underlying top-down
and bottom-up causes.
