Dr Mike Wheeler joined the University of Worcester in 2010 after researching in the area of plant molecular genetics. Mike developed a strong background in the biology of cell signalling in plants, with specific research into the mechanisms of self-incompatibility in poppy and the control of polarity in pollen tubes of tobacco. He is currently investigating the function of a large family of secreted proteins likely to be involved in cell-cell communication in the model plats, Arabidopsis thaliana and Physcomitrella patens.
In addition to his research into plant molecular genetics Mike is also developing means of using molecular biology to solve problems in conservation biology which is a longstanding passion of his. In this area Mike is currently developing eDNA (environmental DNA) techniques to assess the effect of invasive and non-native species on species of conservation concern.
Mike is a member of both the Plant Molecular Genetics research group and the Ecology and Environment Research Group at the University of Worcester.

- Research Interests
1 - Plant Cell Signalling
My interest in this area stems from research that I carried out for my PhD at the University of Birmingham which resulted in the isolation and characterisation of the pollen receptor that controls self-incompatibility (SI) in the field poppy, Papaver rhoeas (Wheeler et al 2009). The SI system in poppy is controlled by polymorphic secreted ligand proteins (PrsS) and a pollen-specific membrane receptor (PrpS). While no homologues of PrpS have been found in other plants there are known to be homologues of PrsS, the secreted ligand protein (Ride et al 1999). These proteins are found as a large family (84 members, figure 1) in Arabidopsis thaliana and also in the model moss, Physcomitrella patens.
A current focus of my research is to elucidate the function of these proteins. We know that these proteins are secreted as they each have an N-terminal signal peptide and immunogold studies suggest they localise outside of the cell (figure 2). The Arabidopsis SPH family members are mostly expressed in floral tissues with some being pollen-specific and many others ovule-specific. However one problem with this family is that they appear to contain many duplicate copies and thus are difficult to analyse using traditional gene knockout strategies. I am currently attempting to elucidate their function by misexpressing and overexpressing pollen-specific and ovule-specific SPH proteins in Arabidopsis.
Because of the difficulties of studying such a large family of genes I am also currently examining the SPH gene family in Physcomitrella patens in association with a colleague at the University of Birmingham, Dr Juliet Coates. The advantage of using Physcomitrella is that there are only 6 SPH genes and the Physcomitrella genome is also known to have less duplication of genes. Additionally this plant is amenable to targeted gene replacement by homologous recombination. I am currently investigating function of these genes via a gene knockout and reporter fusion strategy. In addition I am using a phage display strategy to attempt to find receptors for these proteins.
If you are interested in an opportunity to take part in this research by doing the MRes Biology at the University of Worcester. Please contact Mike Wheeler (firstname.lastname@example.org).
2 – Molecular Ecology
I currently have two projects in Molecular Ecology. In both of these I am seeking to use molecular methods to enhance the ability of conservation scientists to carry out survey work.
eDNA to test streams for native white-clawed crayfish (Austropotamobius pallipes) and non-native signal crayfish (Pacifastacus leniusculus).
I am currently optimising a method for analysing stream water in the Wyre Forest where there are populations of both red-listed white-clawed crayfish and signal crayfish which is an invasive American species. This project is being carried out in conjunction with Dr Graham Hill who has built up excellent knowledge of the ecology of crayfish in the Wyre Forest. Annual surveys are carried out and at present the population in this location appear to be stable. The presence of both species so close to each other also gives us a unique insight into the interaction of an invasive species on endangered native species and it is hoped in the future we can carry out some population genetic work on the two species in the Wyre Forest to examine changes in the population over time.
I am currently optimising the eDNA detection technique in association with a recent graduate, Niken Pam
eDNA to test for the impact of released pheasants on native reptile species.
Little work has been done on the impact that released pheasants may have on native species where they are released (sometimes in large numbers). In a project in conjunction with Dr Duncan Westbury I am currently involved in testing whether it is possible to assess the impact of pheasants by examining scat using an eDNA technique specifically to examine the possibility that pheasants predate young reptiles using material kindly provided to us by Reeseheath College. The current work is being undertaken by a recent graduate, Jemma Roberts and builds on work done previously by Rory Dimond a successful Worcester graduate who now works for the conservation charity Buglife.

- In addition to the projects above I have also been involved with a project by an MRes student, Dominique Cragg, examining the effects of farmland management on Corn Buntings. Population Decline of Corn Buntings.
I would also be pleased to hear from anyone who wants to collaborate on projects that utilise molecular markers in Population or Conservation Biology. If you are interested please contact me at email@example.com.
