About

My research interest is in understanding development and evolution, particularly in plants. I run a small research group who work primarily with moss and Arabidopsis; we also grow liverworts, spikemoss, grasses, green seaweeds and microalgae. We use molecular genetics, cell biology, developmental biology and ‘omics approaches to understand gene and protein function in these systems.

I am currently a Royal Society-Leverhulme Trust Senior Research Fellow.

Biography

Juliet spent her formative years growing up in Brighton. She carried out her undergraduate degree in Cambridge and then moved to London for her PhD, living and working north of the river with regular forays south to appreciate the Tate Gallery, the Royal Festival Hall and the Ministry of Sound.

She carried out her first postdoctoral position at the MRC Laboratory of Molecular Biology in Cambridge, in Mario de Bono’s lab. She worked on the molecular and cellular mechanisms underlying behaviour in C. elegans and spent considerable time picking worms on what was at one time Sydney Brenner’s bench.

She then crossed over the great evolutionary divide to “the green side” having been awarded an independent postdoctoral fellowship (Gatsby Charitable Foundation Interdisciplinary Research Fellowship) and worked for 3 years in the Department of Plant Sciences at the University of Cambridge, investigating Armadillo-related proteins in Arabidopsis.

In 2004 she accepted a position as a lecturer in Plant Molecular Genetics in Birmingham. She has a young son and currently works part-time.

Plant development, cell biology and evolution

We are interested in plant evolution and development: in all kinds of plants!

Complex organisms such as animals and plants are composed of many cells. The evolution of many-celled (multicellular) organisms from single-celled ancestors is one of the most important steps in the history of life on earth. Very little is known about how this critical event occurred.

In multicellular organisms, cells acquire particular identities by responding to signals that tell them which genes to turn on, and therefore which proteins to make. Each cell type contains a different combination of proteins. This process of acquiring specific cell identities to make a viable organism (such as a plant with leaves, flowers and roots) is called “multicellular development”.

Moss

The ancestral single-celled organism that gave rise to animals and plants existed around 1.6 billion years ago. When plants colonised the land, an explosion of plant multicellular evolution occurred from simple water-dwelling green algae. The transition of plants from water to land (around 500 million years ago) was a giant leap in plant evolution and allowed plants to colonise just about every square inch of the globe. It also led to a dramatic increase in the size and complexity of plants.

It is thought all multicellular organisms, including plants, evolved from a relatively small number of single-celled ancestors. Thus, certain fundamental molecular processes controlling multicellular development are likely to be shared by all species. We would like to find out what these processes are!

Why is this important?

Algae and plants are a fundamental part of life on earth. They are integral to our atmosphere, our ecosystems and our society (for food, fuel and much else besides). Most of the complex land-dwelling plants we use in every day life evolved in the last 200 million years. This leaves a “hole” of at least a billion years during which we have very little idea of what was going on in terms of plant evolution. So, understanding how plants got to be the way they are is one of the most under-investigated areas of modern biology.

Over the last decade or two there has been an increased scientific interest in plant biology, probably for a couple of reasons. Firstly, we eat plants. Pretty much everybody depends on one or more members of the grass family (rice, wheat, etc) to provide their staple source of carbohydrate. Growing enough crops in the right places to sustain current world population growth is becoming increasingly challenging; we need to find ways to make plants grow in places that they would not normally be able to. The second reason is that many of the scientific tools that allowed us to understand a great deal about how bacteria, yeasts and animals work at the molecular level, including genetic engineering, can now be used to understand plant biology too.

If we can trace the evolutionary history of the plants we see around us we stand a better chance of being able to use them in a productive way. For example, by understanding how ancient plants made the journey to land, we can identify their drought-resistance strategies and manipulate modern crops to be more drought-resistant when required. In addition, algae are highly adaptable and can live in a huge variety of inhospitable environments. If we could encourage plants to use these algal mechanisms we could grow plants in a diverse range of habitats all over the globe. Algae also provide a potential untapped resource of fuel that could be grown in the water rather than taking up valuable space on land.

What do we actually do?

1) Conserved genes and proteins for multicellular development

 One of our key research interests is in evolutionarily ancient proteins that are required for multicellular development in animals, amoebae and plants (e.g. Armadillo-repeat proteins, GSK3s, Tetraspanins). We are currently investigating protein function in an “up-and-coming” and evolutionarily ancient model plant, the moss Physcomitrella patens, which evolved around half a billion years ago. Comparing these functions in Physcomitrella, Sellaginella, rice and Arabidopsis will give us insights whether our proteins of interest proteins are part of evolutionarily conserved developmental signaling pathways.

Collaborators: Rita Tewari, Liz Bailes, Karen Bunting, Peter Winn and Mike Tomlinson.

2) Regulation of plant root architecture

We are interested in signals and proteins that control how roots branch to form a network. This is a developmental process of huge agricultural importance, and is critical for plant growth and responses to changing environments. We investigate root branching mechanisms in Arabidopsis, and plan to use our Arabidopsis data to inform research to manipulate root development in cereals and grasses

Collaborators: Malcolm Bennett, Susana Ubeda-Tomas and Ilda Casimiro.

3) Studying complex algae

The oceans are still full of both single-celled and many-celled algae. Their conversion of sunlight into sugars drives nearly all other ecosystems, thus we are totally dependent upon them. They represent a relatively “untapped” reserve of biofuels. However, too many algae can have a negative environmental impact, causing destructive algal “blooms”. Almost nothing is known about the genetic complement of algae, particularly complex and multicellular algae, which have some similar characteristics to land plants. We plan to use new high-throughput technologies to sequence and analyse a diversity of algal transcriptomes.
