The 7th International Plant Phenotyping Symposium, IPPS2022


7th International Plant Phenotyping Symposium:

"Plant Phenotyping for a Sustainable Future"


Food security, managing population growth and improving crop yields in the face of climate change are some of the greatest challenges facing our global society. We will need to produce food for 9.7 billion people in a sustainable way by 2050, whilst transitioning from a fossilbased economy towards a bioeconomy to mitigate the effects of global climate change.

This will require a fast increase in global crop productivity to produce enough plant biomass to achieve both food and nutrition security, as well as to meet the demands of a future bioeconomy. Crop production must be increased whilst maintaining crop quality. Society will require crops that combine sustainability, efficient use of scarce resources, e.g., water and mineral fertilizer, and are suitable for cultivation schemes and practices that preserve the Earth’s biodiversity. Current intensive cropping systems will need to become more sustainable, and more crop varieties must also meet the needs of the agroecology, organic and urban/vertical farming sectors. “Future-proofed” crops must have good yield stability with a high resilience to adverse climate, volatile weather conditions and biotic stresses. To meet these aspirations, both current and new crop plants need to be optimized and adapted which will require an ultimate effort both from the plant sciences as from the private sector. And in this process, the availability of versatile, high-throughput plant phenotyping methodology and infrastructure will be an absolute requirement for success. For this reason, we are very excited that over 400 scientists and members of the private sector have come to Wageningen to the 7th International Plant Phenotyping Symposium, IPPS2022, to present and discuss their latest results and developments in the field of plant phenotyping and to advance the field further towards a sustainable future.

Phenomics for genebanks – future prospects (Seed and Germplasm Phenotyping Working Group – Workshop)

Recent advances in controlled environment phenotyping and lab-to-field translation (Controlled Environment Plant Phenotyping Working Group – CePPG Workshop)

Summary: Analyzing the phenotypes of plants growing under controlled environmental conditions is a requirement if one would like to investigate molecular-physiological mechanisms and biological processes of plant performance at the cellular, organ, whole plant, and canopy level.  Use of controlled environments also enables repeated and independent testing of experimental outcomes, a fundamental requirement in research. Climate controlled plant cultivation facilities can furthermore be used to simulate future environmental scenarios to which plants need to be adapted to in order to achieve the required high performance and strong resilience. However, in the past, only little attention was paid to the fact that plants grown under usual controlled conditions can be phenotypically very different from those in the field. This workshop will explore recent advances to apply controlled conditions in such a way that experiments are repeatable and relevant to present and future field conditions.

Advancements in Forest & Tree Phenotyping (Forest Phenotyping Working Group – Workshop)

Summary: During this workshop the FPWG will host a series of talks from leading international researchers on the current & future frontiers of forest & tree phenotyping. The workshop will also host an open discussion session before finishing, to provide opportunities for participants to interact and initiate lines of discussion and networks. From genetics through remote sensing to impactful data analysis, the workshop aims to present the latest tools and sciences that reveal the phenotypic traits of forests and trees.

Advanced Sensor Applications working group assembly (Satellite Meeting)

Summary: Assembly of the members of the working group & anyone interested. Presentation of the working group to the audience and definition of activities for the next period. The scope of the workshop is to update the members about the topics within the working group and to include everybody in the planning of the activities within the next year. Additionally, we will discuss how plant sciences could leverage from the physical sensor information in more depth for complex trait discovery.

Measuring photosynthesis: bridging the gap between high and low throughput (WUR)

Summary: Screening large numbers of plants via high throughput phenotyping is an excellent method to study phenotypic and genetic variation. Yet, photosynthesis is difficult to characterize in high throughput phenotyping, as it is invisible and strongly environmentally dependent. Many methods to quantify photosynthesis and processes related to it exist, but currently only some of these can be used for ‘snapshot’ measurements. This workshop aims to list methods available to us for characterizing photosynthesis at the leaf, plant or stand level, and to find ways to bridge the gap between ‘slow and accurate’ and ‘quick and dirty’.

The workshop is intended as an inventory of the various methods used to quantify traits related to photosynthesis, with an emphasis on implementing these methods in high-throughput plant phenotyping. Methods will be compared on their advantages and shortcomings with regards to accuracy and speed.

We will start off the workshop by a series of short (10 min) talks on some key methods, including: i) chlorophyll fluorescence imaging, ii) photosynthetic gas exchange, iii) hyperspectral imaging, iv) stomatal conductance phenotyping (including but not limited to thermography), and v) absorbance change imaging. Then, participants are split into several groups for round-table discussions, where they are asked to list and discuss advantages and disadvantages for given methods. Finally, results from the different groups will be brought together in one big overview, and discussed. A final deliverable of the workshop could be a large poster that presents an overview of the status quo and future directions, which could be presented at the main symposium in the days after the workshop.
