个人简介
A key driver for my move to UEA in 2011 was the opportunity to pursue a leadership role as Executive Dean of the Faculty of Science, alongside the opportunity to maintain my research on the molecular genetics of plant breeding systems.
I graduated in Genetics from the University of Leeds in 1983, and completed my PhD at Warwick University in 1986 where I worked on the isolation and characterisation of light-responsive genes in Pisum sativum with Professor John Ellis FRS. I then spent a postdoctoral year with Professor Mike Lord on the development of Ricin as an immuno-toxin.
I moved to New York in 1987 where I held a SERC-NATO Independent Fellowship in Professor Nam Hai Chua’s laboratory at The Rockefeller University. There I worked on light-regulated transcription and the characterisation of molecular light switches through which light-responsive gene expression is modulated, characterising both cis-regulatory promoter elements and their associated transcription factors. A second Independent Fellowship at The Rockefeller University from the Winston Foundation extended my work on light-regulated gene expression for a further two years.
I returned to the UK in 1991 to take up a faculty position at the University of Leeds where I continued work on light-responsive transcription, with a focus on the GATA family of plant transcription factors in Arabidopsis thaliana. I also established projects on plant sex determination and floral heteromorphy which remain the focus of our current research.
At the University of Leeds I taught on a wide range of courses and also took on a range of additional responsibilities. In 1998 I became Director of the Centre for Plant Sciences, and in 2004 became pro-Dean for Research in the Faculty of Biological Sciences.
In 2007 I moved to Durham University as Principal of St Mary’s College. This move enabled me to contribute to a University role that focused on the student experience in a collegiate system. This position not only provided considerable opportunity for student and alumni engagement, but also enabled me to maintain my research interests and refocus my laboratory on the molecular genetics of plant breeding systems.
In 2011, I moved to UEA as Executive Dean of the Faculty of Science in an environment where I can pursue my research interests and benefit from the unparalleled collaborative opportunities offered by the Norwich Research Park. Current research focuses on plant sex determination in Silene dioica and floral heteromorphy in Primula vulgaris with funding from the BBSRC and Leverhulme Trust.

研究领域
Research in our lab is focused on plant breeding systems that involve development of different forms of flowers on plants of the same species. We focus primarily on two experimental models, floral heteromorphy in the Primula species, and sex determination in Silene species with the aim of identifying and characterising the molecular genetic mechanism that underpin these reproductive strategies.
Floral heteromorphy is a characteristic of, but not limited to, the Primulaceae and epitomised by Primula vulgaris, the common primrose. Individuals develop one of two forms of flower, known as pin and thrum. Pin flowers have a long style that presents the stigma at the mouth of the flower, with anthers attached midway down the inner corolla tube. Thrum flowers have a short style and anthers attached to the inner corolla wall at the mouth of the flower. This reciprocal positioning of male and female reproductive structures, known as reciprocal herkogamy, promotes insect-mediated cross pollination. These characteristics, and other features of floral heteromorphy, including differential pollens size and a sporophytic self-incompatibility system, are controlled by a co-adapted linkage group known as the S locus. Pin plants are homozygous recessive (s/s); thrum plants are heterozygous (S/s). BBSRC funding supports our work on the Primula S locus and we are working towards the identification and characterisation of the S locus genes that orchestrate floral heteromorphy. Using a combination of classical genetic analysis, molecular genetics techniques, genome sequencing, mutagenesis and screening, alongside plant transformation approaches we have made significant progress towards identifying the key genes controlling pin and thrum flower development.
In dioecy, separate male and female flowers are produced on different individuals as exemplified by Silene dioica, red campion, and S. latifolia, white campion. Sex determination in these species is controlled by heteromorphic sex chromosomes. Females have two X chromosomes; males have an X and a Y. The dominant male determining Y chromosome suppresses carpel development, promotes stamen development, and is required for pollen production. In the absence of a Y sex chromosome, carpels develop normally but stamens arrest at the primordia stage. Infection of dioecious Silene with the anther smut fungus Microbotryum violaceum causes development of anthers in genetically female flowers; the pathogen mimics the Y chromosome-encoded signal for male reproductive development. We are working to define the sex determination genes on the male-determining Y chromosome responsible for suppression of carpel development and promotion of stamen development, and to identify the Microbotryum-derived signal for another development. Funding from the Leverhulme Trust supports work on characterisation of an unstable mutation in a flower pigment gene that leads to red and white sectored variegated flowers in S. dioica. We are working towards using the transposon responsible for this instability locus as a tool for reverse genetic approaches to identify key sex determination genes.
Our laboratory is located within the John Innes Centre on the Norwich Research Park. If you are interested in pursuing PhD or post doctoral research opportunities in our group working on either of our model systems, please email me directly p.gilmartin@uea.ac.uk
