drought stress

Last chance to secure an internship – apps close tomorrow!

This is your chance to investigate your plant science questions with the support of the highly skilled Australian Plant Phenomics Facility (APPF) team and the incredible technology and infrastructure we have available.

Internships are offered at the APPF in Adelaide and Canberra for enthusiastic, highly motivated postgraduate students with a real interest in our research and technology. Current postgraduate students in the following areas are encouraged to apply:

  • Agriculture
  • Bioinformatics
  • Biology
  • Biotechnology
  • Computer Science
  • Genetics
  • Mathematics
  • Plant physiology
  • Science
  • Software engineering
  • Statistics

Interstate students are strongly encouraged to apply!

We offer postgraduate internship grants which, in general, comprise:

  • $1,500 maximum towards accommodation in Adelaide or Canberra, if required
  • $500 maximum towards travel / airfare, if required
  • $10,000 maximum toward infrastructure use

The APPF has identified a number of priority research areas, each reflecting a global challenge and the role that advances in plant biology can play in providing a solution:

  • Tolerance to abiotic stress
  • Improving resource use efficiency in plants
  • Statistics and biometry
  • Application of mechatronic engineering to plant phenotyping
  • Application of image analysis techniques to understanding plant form and function

Students proposing other topics will also be considered.

APPF postgraduate internship grants involve access to the facility’s phenotyping capabilities to undertake collaborative projects and to work as an intern with the APPF team to learn about experimental design, image and data analysis in plant phenomics.

Selection is based on merit. Applications are assessed on the basis of academic record, research experience and appropriateness of the proposed research topic. Interviews may be conducted.

Postgraduate students are encouraged to contact APPF staff prior to submitting their application to discuss possible projects.

APPLICATIONS CLOSE:  31 March 2017. For further information click here.

 

Why apply for an internship with the APPF?

Well, aside from the fact we are a pretty nice bunch…

PhD student Rohan Riley, from Western Sydney University, undertook his research at APPF’s Adelaide node (The Plant Accelerator®) after being awarded a Postgraduate Student Internship Grant with us in 2015.

His research attempted to explain the unpredictability of plant growth responses in terms of resource limitation by introducing fungal communities to plants which are isolated from soils containing high or low levels of salinity and analysing the effects on plant stress at the phenotypic level.

This is what he had to say about his experience:

”Using daily phenotyping following the application of salt stress and controlled watering-to-weight in The Plant Accelerator® allowed for an unprecedented resolution and range of plant genetic changes in response to combinations of nutrient level, salinity and two different fungal communities that would not otherwise be achievable in a regular greenhouse,” said Rohan.

”As a PhD student with limited experience in greenhouse experiments, the highly controlled growth conditions, large-scale automation, digital imaging and software technology (high-throughput phenotyping) at The Plant Accelerator® provided me with the work-space, expertise and technical support to make a complicated experiment possible.”

“It has been an amazing experience to conduct this experiment at The Plant Accelerator®. I am walking away from the facility with a big smile on my face, an incredible dataset for my PhD research and invaluable experience in greenhouse based plant research.”

Getting to the root of the problem wins

Congratulations to Olivia Cousins, one of the Adelaide-Nottingham PhD students, who won the student poster prize at a joint conference between Soil Science Australia and New Zealand Soil Science Society, held in Queenstown, NZ recently.

Olivia’s poster, which included co-authors from The University of Adelaide, The University of Nottingham and The Plant Accelerator® at the Australian Plant Phenomics Facility, was one of approximately 100 posters presented at the conference. The award also includes a cash prize for Olivia.

We announced Olivia’s study here in our blog in May. The aim of her study was to quantify the impact of different soil moisture regimes and increasing levels of soil nitrogen supply on shoot and root response in wheat plants. Olivia’s experiment utilised the DroughtSpotter, a precision irrigation platform allowing accurate and reproducible water application for drought stress or related experiments. She also used the facility’s PlantEye laser scanner to non-destructively measure plant growth.

Olivia plans an exciting move to Nottingham in 2018 to continue her research including root traits and responses across different wheat species.

The Australian Plant Phenomics Facility is available to all researchers and/or industry. For bookings please contact Dr Trevor Garnett.

 

 

Drip-fed success

The Australian Plant Phenomics Facility (APPF) is pleased to announce the new DroughtSpotter precision irrigation platform has been fully tested and commissioned, and is now ready to support your plant phenomics research.

The DroughtSpotter is a gravimetric platform with precision irrigation allowing accurate and reproducible water application for drought stress or related experiments.

A number of pilot projects were carried out to test the platform with excellent results.

Monash University researchers, led by Associate Professor Ros Gleadow, investigated the impacts of dhurrin (a chemical that is toxic to grazing animals) on drought tolerance in sorghum plants. Plants were grown under a range of drought stresses and then harvested throughout growth for biomass characterisation, metabolomics and transcriptomic responses.

“We found the DroughtSpotter to be an excellent platform to apply accurate, reproducible amounts of water to large numbers of individual plants for growth and compositional analysis under different levels of water limitation,”said Associate Professor Gleadow.

Led by Professor Steve Tyerman, researchers from the ARC Centre of Excellence in Plant Energy Biology at the University of Adelaide and TA EEA-CONICET Mendoza, Argentina investigated the relationship between hydraulic and stomatal conductance and its regulation by root and leaf aquaporins under water stress.

“A better understanding of these mechanisms is highly relevant to irrigation scheduling and to ensure sustainable vineyard management in a context of water scarcity” said Professor Tyerman.

“The DroughtSpotter platform allowed us to achieve precise control over soil moisture and vine water stress, which was the most critical aspect to the success of this project.”

The DroughtSpotter greenhouse is available to all publicly or commercially funded researchers. For further information, please visit the APPF website or contact Dr Trevor Garnett.
