*Genomics of the biomass crop Miscanthus: characterizing variation in the
plastid genome and assessing nuclear polyploid variation*
A three-year PhD fellowship funded under the Wash Fellowship Schema is
available for a research project on the biomass crop plant Miscanthus.
Miscanthus species are perennial, C4 grasses capable of tremendous biomass
growth under a wide range of climatic conditions. Attention has focussed on
biomass crops because of the need for alternative energy sources for
sustainable living. Very few Miscanthus genotypes have been assessed for
their biomass potential but work is underway to develop new genotypes. The
overall aim of this project is to gather essential genomic information
required for plant breeding in this poorly understood genus. The focus will
be on the characterization of the nuclear and cytoplasmic gene pools. The
entire chloroplast genome sequence will be sequenced, partial sequences of
the mitochondrial genome will be generated and chromosome number and ploidy
variation recorded for the nuclear genome.
We will use DNA sequencing and bioinformatics techniques to assess the
sequence information of the Miscanthus organelles. We will study their
features via annotated genome diagrams and via comparisons to other grasses
especially sugarcane, sorghum and maize. Structural rearrangements will be
recorded and assessments made of the molecular evolution of their genes. We
will assess the cytoplasmic gene pools available for breeding by developing
and applying molecular markers (including but not exclusively SSR variants)
suitable for rapid screening of diversity. Furthermore we will use flow
cytometry in conjunction with chromosome counts to assess polyploid
complexes. We will determine crossability groups and gather essential
information for future ploidy manipulation.
This is a collaborative project between Teagasc Crops Research Centre Oak
Park in Carlow and the Botany Department of Trinity College Dublin (TCD).
The researcher will be based in Oak Park but can spend some research time at
TCD. The student will receive an annual tax free stipend of €21,000 for
maintenance and to cover University fees (currently €4,708 pa for EU
citizens, €12,067 pa for non-EU citizens). The PhD project is funded for
three years and is expected to start on 1st October 2007.
Applicants must have or expect to gain a first or upper second class or
Masters degree in an area of biological sciences. Informal enquires are
welcomed and further information is available from the co-supervisors
(below). Applications, including a covering letter detailing research
interests and aspirations, a detailed CV including names and contact details
of two referees should be made to Trevor Hodkinson (hodkinst@...;
http://www.tcd.ie/Botany/staff/THodkinson.html
or Susanne Barth (susanne.barth@...;
http://www.teagasc.ie/oakpark/sbarth.htm) as soon as possible; the position
will be open until filled.
