PhD position in plant evolutionary biology, University of Zurich.
University of Zurich, Dept. of systematic and Evolutionary Botany

RESEARCH PROJECT: Genetic basis of hornwort carbon-concentrating
mechanisms.

Biophysical carbon concentrating mechanisms (CCMs) operating at the
single-cell level have evolved independently in some eukaryotic algae and
a single lineage of land plants, the hornworts. An essential component
for an efficient biophysical CCM is a pyrenoid, which represents a
specialized compartment inside chloroplasts that mainly comprise the
CO2-fixing enzyme RuBisCO. Hornworts with pyrenoids fix significantly
more carbon than their relatives without pyrenoids. Given the repeated
gains and losses of pyrenoids in hornworts during the last 50 million
years, we may assume that their assembly is potentially controlled by a
few master regulators of eco-evolutionary relevance. In a joint effort,
we will combine comparative -omics with reverse genetics tools to study
the genetics, function, and molecular basis of pyrenoid-based CCM in
hornwort plastids under different environmental conditions. Guided by
ultrastructure-based monitoring of the pyrenoid assembly in hornworts,
we aim to identify the genetic toolkit of biophysical CCM in hornworts
through two interdependent approaches: First, we aim to predict candidate
CCM components in silico though a set of homology searches that compare
the hornwort gene set with algal CCM component. Second, we employ an
exploratory gene and protein (co)expression profiling of isolated plastids
collected under low vs. high CO2 concentrations and under flooding. A
strength of our experimental design is that we contrast up to three
pairs of pyrenoid bearing and pyrenoid lacking hornwort species. Finally,
we will investigate pyrenoid functionality under various environmental
conditions. Specifically, we aim to conduct localization and functional
validation analyses for a core set of genes discovered in our CCM gene
prediction approaches. These experiments are possible through our recent
advances to establish Anthoceros agrestis and other hornwort species as a
tractable model system. Together, our collaborative project will not only
allow a comparison of the mechanisms of pyrenoid assembly between algae
and hornworts, but also reveal general principles and species-specific
innovations in the evolution of carbon-concentrating plastids. Above that,
focusing on and understanding the basis of land plant CCM instead of
only the algal form could eventually contribute to efficiently engineer
pyrenoid assembly and boost photosynthetic efficiency of crops. Relevant
publications: https://www.nature.com/articles/s41477-020-0618-2,
https://doi.org/10.1016/j.tplants.2017.02.002.

This project is founded (initially for three years) by the German National
Science Foundation (DFG) MadLand (https://madland.science/) program to
Peter Szovenyi and Susann Wicke. The project requires collaborative work
including frequent visits to Germany and to the USA (Fay-Wei Li`s lab
at Cornell).

The Dept. of Systematic Botany hosts research groups working on
the evolutionary and ecological drivers of biodiversity, on the
macroevolution of plants, on plant-insect interactions/pollination,
on the evolution of mating systems, hybridization and speciation. The
Dept. of Plant and Microbial Biology hosts many groups working on plant
molecular and developmental biology, epigenetics, community genomics and
plant adaptation. Both institutes are housed in the beautiful Botanical
Gardens and host a diverse community of researchers in plant biology.

Ideal candidates will have an MSc in biology with a specialization in
evolution, developmental genetics and/or bioinformatics. This position
primarily involves reverse genetic, microscopy, gas exchange measurements
and bioinformatic work and requires advanced skills in handling, analyzing
and interpreting high-throughput next-generation sequencing data. Good
skills in assembling vectors, carrying out genetic transformations and
microscopy are also required. Previous experience with Chlamydomonas
pyrenoids is a plus but not necessary. In case not all these skills
are covered, the willingness to quickly acquire them is absolutely
necessary. The student will closely work together with the second
PhD student/postdoctoral associate in Germany on this grant. Students
should be willing to work both in the wet lab and in the office doing
computational work. The position is initially for three years. Selected
candidates will be enrolled in one of the two affiliated PhD schools in
evolution or plant sciences.

CLOSING DATE: The position is opened until filled, but all application
material including CV, a summary of research experience, a letter of
motivation, copies of relevant publications (published or submitted)
and names and contact information of three reference persons sent as
a single pdf file should be received by 31th July 2020 to ensure full
consideration. The position will start at the earliest possible date,
but it is negotiable (at the latest in September 2020). Candidates should
indicate in a cover letter when they could take up the position.

Please send all application material with the following subject line
“PhD_hornwort_pyrenoid” to: Peter Szovenyi, peter.szoevenyi@uzh.ch,
as a single pdf document. For enquiries please contact Peter Szovenyi

PhD in plant evolution (UK)

Royal Botanic Garden Edinburgh and the University of Glasgow.
Linking the genome to the niche in the mega-diverse genus Begonia
PhD scholarship

Abstract
Begonias are one of the largest groups of flowering plants in the world,
with nearly 2000 species. They are very successful at colonising deeply
shaded habitats in the tropical forest understory, often growing where
few other plants can survive.  Why are there 2000 species, and how are
they different? Answering this question will give us insights into why
the tropics hold so much of the world's biodiversity. To what extent
do begonias differ in tolerating deep shade, which is a very important
part of their strategy for survival? To answer this we need to compare
the light levels that a number of different species get from dawn to
dusk by measuring it in the forest where they grow. There may be other
important factors in the habitat that may differ from site to site,
such as temperature, humidity and soil characteristics, so we also need
to measure those. From this data we can see how much the conditions
each species grows in differ. What would make each species do better
under different conditions? To answer this we need to look at their
ecophysiology, for example examining photosynthetic efficiency, how the
leaf surface might vary in order to capture light of different intensity
or angle, or how the stomata are arranged and controlled. To complete
the picture of how begonia species differ, we can use our database of
begonia genes to identify genes variable between species, focusing on
those which may be involved in ecophysiological traits. We can sequence
these from the same species we have habitat and ecophysiology data
for to determine if  the sequence variation is linked to adaptation to
particular niches. There is the potential to use interspecific genetics
or transgenics to  further investigate functional links between particular
genes and niche adaptation.

Applicants should be highly motivated with an excellent academic record,
with a first degree in a relevant subject of at least upper second
or equivalent. The project will require competence in molecular lab
skills and the ability to withstand several months over the course of
the project in the field in Indonesia.

The studentship is funded by the M. L. MacIntyre Begonia Trust, and is
open to applicants liable for tuition fees at the Home and EU rate. The
stipend is £13590 per annum. The start date will be in September-October
2013, with a closing date for applications of August 30th 2013. Applicants
should send a cover letter explaining their interest in the project,
and highlight any relevant experience and publications. The successful
applicant will be based at the Royal Botanic Garden Edinburgh, with the
degree being awarded by the University of Glasgow. For more information
please contact either Dr Mark Hughes or Dr Catherine Kidner.

Postdoc position in Plant Evolutionary Genetics

Postdoc position in Plant Evolutionary Genetics at Newcastle University,
UK.  We are looking for an enthusiastic postdoc for a 3-year NERC-funded
research project entitled: 'Inter-genomic conflict in gynodioecy and
its effects on molecular evolution of mitochondrial genomes in the
genus Plantago'.

The applicant will be based in Kirsten Wolff's group in the School
of Biology, Newcastle University, and will collaborate closely with
Deborah Charlesworth's group at the Institute of Evolutionary Biology,
University of Edinburgh, where an additional postdoc will be part of
the same project.

This project will use molecular evolutionary approaches to investigate
the maintenance of cytonuclear polymorphisms in gynodioecious plants
in the genus Plantago, to test whether an 'arms race' situation
prevails, versus long-term balancing selection. In the project we
will be obtaining and analysing DNA sequences of multiple nuclear
and mitochondrial genes, to compare diversity, and test for long-term
balancing selection. Non-gynodioecious species will be studied, as well as
gynodioecious ones, to provide outgroups for sequence analyses and to test
whether the high diversity expected under long-term balancing selection
is confined to the gynodioecious species. The project also includes
testing for paternal inheritance/leakage by testing for heteroplasmy in
natural populations of P. lanceolata, using analyses of mitochondrial
DNA sequence haplotypes and studies of offspring of reciprocal crosses
to assess the possibility that within-species polymorphism could explain
the highly elevated mutation rates estimated in Plantago lineages.

The work will be divided between Edinburgh and Newcastle. For example,
the Edinburgh group will concentrate on the nuclear genes, while the
Newcastle group will obtain the mitochondrial genes, while other work
is shared. Field work and greenhouse work will predominantly be done by
the Newcastle postdoc.

Applicants must have completed their PhD before starting the position.
Applicants should have some experience with molecular genetic techniques,
and an interest in population genetics.

Further information can be obtained through vacancy information available
on the Newcastle University web site, reference number D1082R. On the
web site http://www.ncl.ac.uk/vacancies/ use this reference number in
your vacancy search and when applying for the job.

Applications must be submitted through this electronic system. The
closing date is: 31st August. Short listing will take place in the week
of 3rd September and interviews are planned for the end of the week of
10th September.

The start date is 1 October 2012 or as soon as possible thereafter.
