Supporting the agricultural industry through R&D to deliver successful new products to market

Developing and bringing new agricultural products to market can be costly and time consuming for industry. Nufarm Limited recently sought the technology and expertise of the Australian Plant Phenomics Facility (APPF) to provide independent testing on potential new foliar sprays under development.

“The full service approach at the APPF, from the technology to the specialist staff, really appealed to us”, said Chad Sayer from Nufarm’s Product Strategy Group.

“The non-destructive, high-throughput phenotyping technology at the APPF gave us the ability to gain insights into our products under development that we could not achieve anywhere else. Their highly skilled, specialist team helped us design our experiments and provided invaluable advice throughout the project, right through to the data analysis.

“This has been exciting for us. Our pilot project delivered such promising results, we already have a large project underway”.

“We have a bespoke approach, working closely with our customers to design their experiments to deliver the best results”, said Dr Bettina Berger, Scientific Director at the Adelaide node of the APPF.

Dr Berger and her colleagues provide consultation on all projects carried out at the Adelaide node, supporting the development of the initial design and execution of the research. The specialist horticultural team set up the experiments and manage them through to completion. Customers can make use of online monitoring and access of projects throughout the experiment stage via Zegami (‘live processing’ which allows result checking on a day-to-day basis). On completion of experiments image analysis and data analysis are handled by our skilled engineering, software and statistics team. The research team then provide consultation on results and further follow-up as required.

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.

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.

Taking the kinks out of curves

In a recent paper, researchers have developed a methodology suitable for analyzing the growth curves of a large number of plants from multiple families. The corrected curves accurately account for the spatial and temporal variations among plants that are inherent to high-throughput experiments.

An example of curve registration.  a The salinity sensitivity (SS) curves of the 16 functions from an arbitrary family, b SS curves after the curve registration, and c the corresponding time-warping functions. The salinity sensitivity on the y-axis of a and b refers to the derivative of the relative decrease in plant biomass

 

Advanced high-throughput technologies and equipment allow the collection of large and reliable data sets related to plant growth. These data sets allow us to explore salt tolerance in plants with sophisticated statistical tools.

As agricultural soils become more saline, analysis of salinity tolerance in plants is necessary for our understanding of plant growth and crop productivity under saline conditions. Generally, high salinity has a negative effect on plant growth, causing decreases in productivity.  The response of plants to soil salinity is dynamic, therefore requiring the analysis of growth over time to identify lines with beneficial traits.

In this paper the researchers, led by KAUST and including Dr Bettina Berger and Dr Chris Brien from the Australian Plant Phenomics Facility (APPF), use a functional data analysis approach to study the effects of salinity on growth patterns of barley grown in the high-throughput phenotyping platform at the APPF. The method presented is suitable to reduce the noise in large-scale data sets and thereby increases the precision with which salinity tolerance can be measured.

Drought knows no borders

The Australian Plant Phenomics Facility (APPF) was delighted to welcome His Excellency Mr Mohamed Khairat, Ambassador of The Arab Republic of Egypt, to its Adelaide node recently.

Egyptians share our love of wheat, however, they are heavily reliant on wheat imports which are struggling to keep up with demand. As a remedy, 1.5 million hectares of Egyptian land has been set aside for local wheat production, but there are challenges ahead. Egyptian wheat growers suffer from the same yield limiting issues of heat and drought as we do here in southern Australia.

While touring the facility, His Excellency shared his enthusiasm for future collaboration with the APPF’s Dr Trevor Garnett.

“There is a wealth of knowledge and experience at the APPF and the Waite Campus of the University of Adelaide in plant phenotyping and wheat production. His Excellency sees exciting opportunities for Egyptian scientists and PhD students to collaborate on research and share ideas on how to improve this essential crop”, said Dr Garnett.
