Fertiliser start-up gets a boost at APPF

Plant Technologist

Resource Recovery Australia together with CSIRO, Cape York Partnership, Balkanu and Kalan Enterprises are developing new income streams for Cape York’s Aboriginal communities by producing organic soil-conditioners from an unlikely source, feral pigs, which cause vast environmental damage to native ecosystems.

A pilot project at the Australian Plant Phenomics Facility’s (APPF) Adelaide node, tested the effect of the ‘Feraliser’ at different concentrations on tomato growth.

“The data collected using the high-throughput phenotyping Smarthouse at the APPF provided valuable insights into the effectiveness of our product. We now know Feraliser performs just as well as the leading organic soil-conditioners currently on the market,” said Emmaline Froggatt from Resource Recovery Australia.

“Feraliser is very much at the start-up phase of development so costs are a big issue for us. The Australian Plant Phenomics Facility provided the information we needed without the expense of a full field trial.”

A step closer to salt tolerant chickpea crops

A recent study has collected phenotypic data of chickpea (Cicer arietinum L.) which can now be linked with the genotypic data of these lines. This will enable genome-wide association mapping with the aim of identifying loci that underlie salinity tolerance – an important step in developing salt tolerant chickpeas.

In this study, Judith Atieno and co-authors utilised image-based phenotyping at the Australian Plant Phenomics Facility to study genetic variation in chickpea for salinity tolerance in 245 diverse accessions (a diversity collection, known as the Chickpea Reference Set).

Chickpea is an important legume crop, used as a highly nutritious food source and grown in rotation with cereal crops to fix nitrogen in the soil or to act as a disease break. However, despite its sensitivity to salt, chickpea is generally grown in semi-arid regions which can be prone to soil salinity. This results in an estimated global annual chickpea yield loss of between 8–10%.

Salinity tolerance phenotyping in a Smarthouse at the Australian Plant Phenomics Facility’s Adelaide node at the Waite Research Precinct – Plants were imaged at 28 DAS for 3 consecutive days prior to 40 mM NaCl application in two increments over 2 days. Plants were daily imaged until 56 DAS. Right pane shows 6-week-old chickpeas on conveyor belts leaving the imaging hall proceeding to an automatic weighing and watering station.

 

The study found, on average, salinity reduced plant growth rate (obtained from tracking leaf expansion through time) by 20%, plant height by 15% and shoot biomass by 28%. Additionally, salinity induced pod abortion and inhibited pod filling, which consequently reduced seed number and seed yield by 16% and 32%, respectively. Importantly, moderate to strong correlation was observed for different traits measured between glasshouse and two field sites indicating that the glasshouse assays are relevant to field performance. Using image-based phenotyping, we measured plant growth rate under salinity and subsequently elucidated the role of shoot ion independent stress (resulting from hydraulic resistance and osmotic stress) in chickpea. Broad genetic variation for salinity tolerance was observed in the diversity panel with seed number being the major determinant for salinity tolerance measured as yield. The study proposes seed number as a selection trait in breeding salt tolerant chickpea cultivars.

Genotypic variation for salinity tolerance in the Chickpea Reference Set. Varying levels of salinity tolerance exhibited by different chickpea genotypes. Exposure of sensitive genotypes to 40 mM NaCl caused severe stunted growth, leaf damage, and led to less number of reproductive sites (flowers and pods) compared to moderately tolerant and tolerant genotypes.

 

The rapid development of new, high-resolution and high-throughput phenotyping technologies in plant science has provided the opportunity to more deeply explore genetic variation for salinity tolerance in crop species and identify traits that are potentially novel and relevant to yield improvement. The Australian Plant Phenomics Facility provides state-of-the-art phenotyping and analytical tools and expertise in controlled environments and in the field to help academic and commercial plant scientists understand and relate the performance of plants to their genetic make-up. A dedicated cross-disciplinary team of experts provides consultation on project design and high quality support.

From lab, to field, to forest!

The Australian Plant Phenomics Facility (APPF) knows no bounds, developing new technologies to ensure that the facility remains at the international forefront of plant science.

We can capture an image of a plant with ease, but how many megapixels does it take to image a forest? Dr Tim Brown would tell you it is 780 megapixels.

Tim and Prof Justin Borevitz from the APPF’s node at ANU have developed a “Gigavision” camera that takes hourly panoramic images made up of 200 x 18MP DSLR photos to create a 780 megapixel image of the forest.

What can a researcher do with this massive image you might ask? The resolution of the image allows researchers to track daily, seasonal and diurnal variation (plant behaviours) in the forest, tree and even leaf levels for thousands of trees in each forest.

Sensing and monitoring tools the APPF is developing at the research forest can be applied to other field ecosystems, such as commercial forests and national parks. Other tools include a pipeline to convert drone flight information into 3D models. APPF staff are available to help individual researchers or research groups set up these field tools at their own field sites.

The ANU research forest at the arboretum is available to national and international researchers for their own field experiments in a unique environment. All data is available for research use upon request.

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.
