Canberra, Camille and the Cropatron…

As the sun rises over another crisp autumn morning in Canberra, you will find French intern, Camille Mounier, keenly watching over her rice lines in the Cropatron at the Australian Plant Phenomics Facility’s node at CSIRO Agriculture and Food.

Her project, ‘A complex system biology approach to understand the factors affecting canopy photosynthesis’, is being led by Dr Xavier Sirault, Director of the node, in partnership with the Chinese Academy of Sciences.

The project team aim to develop system models of canopy photosynthesis for both rice and wheat, in particular, developing novel methods to combine these system models with phenomics data. This approach will help in the identification of the critical factors controlling photosynthetic energy conversion efficiency in C3 species with the view to improving canopy photosynthetic efficiency, and subsequently, crop yields in small grain cereals.

Using the Cropatron platform, Camille will acquire data on canopy growth, gas and energy exchange in order to validate the biophysical photosynthetic model developed by Prof Xinguang Zhu, Head of Plant Systems Biology Group at the CAS-MPG Partner Institute for Computational Biology.

The Cropatron is a PC2 compliant, fully environmentally controlled (temperature, CO2 and humidity) greenhouse equipped with an automated gantry system (operating at 3.5m above the floor) for proxy-sensing imaging of plants grown in mini canopies. The sensing head is composed of an hyperspectral camera (400-1000nm) for measuring chlorophyll pigments, Far IR imaging for proxy sensing of canopy conductance, LiDAR for quantifying canopy architecture and monitoring growth over time, lysimeters for measuring water use at plot level and a gas exchange chamber at canopy level for measuring canopy assimilation.

Academic and commercial plant scientists are welcome to access the Cropatron platform – find out about pricing, availability and bookings here.

 

Taking five with… Michael Schaefer

The three national nodes of the Australian Plant Phenomics Facility (APPF) are home to a highly talented team of plant science researchers and specialists. This passionate, cross-disciplinary team is skilled in areas such as agriculture, plant physiology, biotechnology, genetics, horticulture, image and data analysis, mechatronic engineering, computer science, software engineering, mathematics and statistics. But who are they?

Today we take five minutes to get to know…

Michael Schaefer, PhD

Tell us a little about where you work within the APPF.

I am based at the CSIRO node of the APPF in Canberra. This centre focuses on “deep phenotyping” (delving into metabolism and physiological processes within the plant) and “reverse phenomics” (dissecting traits to discover their mechanistic basis). Here, next generation research tools are being developed and applied to probe plant function and performance, under controlled conditions and in the field.

What do you do there?

I’m a Research Scientist and Team Leader of the Translational Phenomics and Services team. My team looks after all of the new projects that come into our node of the APPF, from dealing with clients directly, to designing experiments based on the client’s needs, right through to providing the final data products and support with analysis.

What is the best part of your job?

As one of the newest team members, the best part of my job has been meeting and working with new people and dealing with new projects in different plants and crops. Every case is different, so designing and running each project is unique which provides a lot of variety.

Where do you see plant phenomics research in 5-10 years time?

I think in 5-10 years’ time plant phenomics research will be very different. We can already see that sensors and technology are getting smaller, faster and cheaper. I think much of what we do with large sensors (lidar for example) will be replaced by much smaller handheld devices or drones that will process data on the fly and give you a result straight away. This will affect all areas of science, not just plant science, so I think it will just be something that we have to adjust to.

“The moment I realised I loved plant science was…”

Somewhere during my undergraduate degree. I was doing straight science, biology, chemistry and physics – very broad – and then I started making links with how physics could be related to the environment (i.e. plants etc.). This seemed to make more sense to me, as I could see the application and how it could directly affect people now, rather than working on something theoretical that may or may not ever be used.

If you could solve one plant science question, what would it be?

For me, I’m really interested in pastures, so it would be the holy grail to be able to accurately, remotely measure above-ground biomass and split it into the green and senesced fractions.

“When I am not working I am…”

At home spending time with my wife Ali and daughter Emilia, or outdoors playing cricket, golf or fishing.

If you could have one super power, what would it be?

Good question…. being able to bend time and space like Dr. Strange. That would be pretty cool!

“If I wasn’t a plant scientist I would be a…”

Fishing guide!

What is your most treasured possession?

They’re not a possession but my family are the most important to me.

If you could have dinner with two famous people who would they be?

Barack Obama and Tiger Woods.

What’s the one thing about you that would surprise people?

I have my private aeroplane pilot licence. I did my pilot training while I was doing my PhD – not that I get to fly much these days.

A better way to tackle environmental variation in your greenhouse research

Statistics prove the smart way to deal with variation in your controlled environment greenhouse.

Plant phenomics allows the measurement of plant growth with unprecedented precision. As a result, the question of how to account for the influence of environmental variation across the greenhouse has gained attention.

Controlled environment greenhouses offer plant scientists the ability to better understand the genetic elements of specific plant traits by reducing the environmental variances in the interaction between genetics and environment.

But controlled environments aren’t as controlled as they seem – variation does exist. For example, some days are cloudy, some are not. The sun, as it crosses the sky, casts shadows differently on plants, depending on their position within the greenhouse. In fact, a recent study by colleagues at INRA in Montpellier showed significant light gradients within a greenhouse and provided sophisticated tools for understanding how much light each plant receives.

One practice for dealing with variation has been to rearrange the position of the plants around the greenhouse during the experiment, however, there is a better way.

The automated high-throughput phenotyping greenhouses at The Plant Accelerator® are controlled environment facilities which use sensor networks to identify and quantify environmental gradients (light, temperature, humidity) in the greenhouses. To further tackle environmental variation, Chris Brien, Senior Statistician at The Plant Accelerator®, led a study that showed good statistical design and analysis was key to accounting for the impact of environmental gradients on plant growth. It was argued that rearranging the plants during the experiment makes it impossible to adjust for the effect of gradients and should be avoided.

The study involved a two-phase wheat experiment involving four tactics in a conventional greenhouse and a controlled environment greenhouse at The Plant Accelerator® to investigate these issues by measuring the effect of the variation on plant growth.

Major investment in plant root phenotyping to answer key questions

It all starts in the roots

Australian agriculture operates in a largely harsh, resource limited (nutrients, water) environment so the role of plant roots is even more vital to crop performance.

While advances in technology have resulted in a tenfold increase in crop productivity over the past century, soil quality has declined. Advanced root systems that increase soil organic matter can improve soil structure, fertiliser efficiency, water productivity, crop yield and climate resilience, while mitigating topsoil erosion — all of which provide near-term and sustained economic value.

It is acknowledged within the international plant science and phenotyping community that root phenotyping is a critical component for crop improvement, but no ideal hardware solution has been developed yet. There is always a compromise between destructive and non-destructive measurement, throughput and resolution, and ultimately, cost.

Recognition of these challenges and increased research investment to find the answers is now coming to the fore in international plant science.

USD $7 million for plant root research granted

Researchers in Penn State’s College of Agricultural Sciences have just received a USD $7 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy, or ARPA-E, to design a low-cost, integrated system that can identify and screen for high-yielding, deeper-rooted crops.

The interdisciplinary team, led by Jonathan Lynch, distinguished Professor of Plant Nutrition, will combine a suite of technologies designed to identify phenotypes and genes related to desirable root traits, with the goal of enhancing the breeding of crop varieties better adapted for nitrogen and water acquisition and carbon sequestration.

“With ARPA-E’s support, we plan to create DEEPER, a revolutionary phenotyping platform for deeper-rooted crops, which will integrate breakthroughs in non-destructive field phenotyping of rooting depth, root modeling, robotics, high-throughput 3D imaging of root architecture and anatomy, gene discovery, and genomic selection modeling,” Lynch said.

“ARPA-E invests in programs that draw on a broad set of disciplines and require the bold thinking we need to build a better energy future,” said ARPA-E Director, Ellen D. Williams.

The project is part of ARPA-E’s Rhizosphere Observations Optimizing Terrestrial Sequestration, or ROOTS, program, which is aimed at developing crops that enable a 50 percent increase in carbon deposition depth and accumulation, while also reducing nitrous oxide emissions (a contributor to greenhouse gas) by 50 percent and increasing water productivity by 25 percent.

UDC Plant Science Centre

Through a € 1.3m investment from Science Foundation Ireland, the Integrated Plant Phenomics and Future Experimental Climate Platform has been established at University College Dublin (UCD) in Ireland. The combination of infrastructure and facilities available to researchers will represent the first of its kind globally.

The platform will be housed in the same building at UCD allowing seamless transition from experiment to scanner. It will consist of a large capacity 3D X-ray CT scanner which uses X-rays taken from multiple angles to non-destructively build-up a 3D image of whole plants and their internal structures, both above and below ground with fast (minutes) scan times and six reach-in, high-spec plant climate chambers with full (de)humidification capabilities. Novel custom additions will include full-spectrum variable LEDs, enabling more accurate representation of sunlight conditions experienced by crops under field conditions. The chambers will integrate thermal imaging to continuously capture leaf temperature and inferred ecophysiological processes (gas exchange).

Breakthroughs in crop/plant/soil/food science will be possible, particularly below ground and at night, because the consequences of climate change or new crop breeds on below-ground /night-time processes have not been readily accessible before the advance of X-ray CT, thermal imaging and integration of these components into an infrastructure platform.

The Centre unites a large number of UCD plant scientists that investigate fundamental and applied aspects of plant science and work alongside industry in exploiting research breakthroughs.

Danforth Plant Science Center

A new industrial-scale X-ray Computed Tomography (X-ray CT) system at the Danforth Plant Science Center in Missouri, USA, is the first of its kind in the U.S. academic research sector dedicated to plant science and can provide accelerated insight into how root systems affect plant growth. The technology was established in late July 2016 under a collaborative multi-year Master Cooperation Agreement with Valent BioSciences Corporation (VBC) and is also supported with funds from a recent National Science Foundation grant.

“X-ray imaging has been a mainstay in medical and industrial research and diagnostics for many decades, yet it is rarely used in plant science,” said Chris Topp, Ph.D., assistant member of the Danforth Center and principal investigator for the project. “The X-ray CT system will allow us to ‘see’ roots in soil and study plants as a connected system of roots and shoots growing in diverse environments.”

“This system is unlike any other in the United States,” said said Keith Duncan, research scientist in the Topp Lab and manager of the new system. “It gives us a great deal of control over the X-ray conditions and will allow us to gather structural data on any object we put into the machine. It provides us with an internal look at not only the root systems, but what’s going on inside the stem and other parts of the plant without taking invasive measures such as removing the plant from the ground or cutting into it.”

In addition to grain crops, this project will also advance research in root and tuber crops such as cassava, potato, groundnut and others that are important for food security in many regions around the globe, but are especially hard to study.

The project combines state-of-the-art technology with computational analysis, quantitative genetics and molecular biology to understand root growth and physiology to assist researchers in understanding roots as they grow in real time in real soil. Both Topp and Duncan agree, this collaboration is just the tip of the iceberg.

“I expect that in a short time, the X-ray imager will catalyze numerous research projects among Danforth Center, St. Louis, national and international researchers that were previously not possible,” said Chris Topp, Ph.D., assistant member of the Danforth Center and principal investigator for the project.

Hounsfield Facility for Rhizosphere Research

The Hounsfield Facility for Rhizosphere Research is a unique platform established with €3.5 million in funding from the European Research Council, the Wolfson Foundation, BBSRC, and the University of Nottingham. It accommodates ERC funded postdoctoral researchers and PhD students, X-ray imaging research equipment and automated growth facilities in one state-of-the-art building and fully automated greenhouse complex.

A key impediment to genetic analysis of root architecture in crops has been the ability to image live roots in soil non-invasively. Recent advances in microscale X-ray Computed Tomography (μCT) now permit root phenotyping. However, major technical and scientific challenges remain before μCT can become a high throughput phenotyping approach.

This unique high throughput root phenotyping facility exploits recent advances in μCT imaging, biological image analysis, wheat genetics and mathematical modelling to pinpoint the key genes that control root architecture and develop molecular markers and new crop varieties with improved nutrient and water uptake efficiency.

The facility’s ambitious multi-disciplinary research program will be achieved through six integrated work packages. The first 3 work packages were designed create high-throughput μCT (WP1) and image analysis (WP2) tools that will be used to probe variation in root systems architecture within wheat germplasm collections (WP3). Work packages 4-6 will identify root architectures that improve water (WP4) and nitrate uptake efficiencies (WP5) and pinpoint the genes that regulate these traits. In parallel, innovative mathematical models simulating the impact of root architecture and soil properties will be developed as tools to assess the impact of architectural changes on uptake of other nutrients in order to optimise crop performance (WP6).
