What is Plant Phenomics?
Phenome = Genome X Environment
Genomics is accelerating gene
discovery but how do we capitalise
on these data sets to establish gene
function and development of new
genotypes for agriculture?
High throughput and high
resolution analysis capacity now
the factor limiting discovery of new
traits and varieties
“ In the next 50 years we must produce more food
than we have consumed in the history of mankind”
Megan Clarke, CSIRO CEO 2009
Phenomics from the Leaf to the Field
Imagine a plant breeder walking his trials logging plant performance distributed sensors
with his mobile phone or logging on to Phenonet from home to view his wheat in real time
HRPPC: Canberra node of the Australian
Plant Phenomics Facility
Role
Deep phenotyping
Development of next generation tools to probe plant
function and performance (come and see us)
Infrastructure:

245 m2 greenhouse
260 m2 growth cabinets
Analytical tools packaged in:
Brachypodium
distachyon
Arabidopsis thaliana
Triticum and Hordeum species,
Vigna unguiculata (cowpea),
Cicer arietinum (chickpea),
Zea mays (maize),
Sorghum bicolor, …
1- Model Plant Module (HTP)
2- Crop-Plant Shoot Module (MTP)

4- Crop-Plant Field Module (HTP)
Gossypium species
Capitalising on new imaging technologies
Plant Morphology
Visible imaging
•Plant area, biomass, structure
•Senescence, relative chlorophyll
content, pathogenic lesions
Plant Function
Far Infrared imaging
•Canopy / leaf temperature
•Water use / salt tolerance
Chlorophyll Fluorescence
imaging
•Physiological state of
photosynthetic machinery
Near IR imaging
•Tissue water content
•Soil water content
FTIR Imaging Spectroscopy / Hyperspectral imaging
•Cellular localisation of metabolites (sugars, protein, aromatics)
•Carbohydrates, pigments and proteins
PlantScan: next generation phenotyping
platform for n-dimensional Models

4-CCD line scanner (NIR and visible
split)
Addressing issues with fluorescence
and environmental control
Automated features extraction and
quantification of n-dimensional models

volume extraction
Sirault, Fripp and Furbank (in preparation)
An integrated phenotyping platform for Model
Plants
•PAM Fluorescence imaging
•Far Infrared imaging
•Visible imaging for growth
•Climate controlled in equilibration
chamber and imaging chambers
2500 plants per day
Applications:
•1001 genomes project - 65 re-sequenced Arabidopsis thaliana ecotypes under analysis - with
Detlef Weigel
•USDA Brachypodium distachyon project

Distributed Sensor Network for Phenomics
Measure and log range of
environmental factors on
field trials.
Zigby wireless transmitters:
Thermopile Temp Sensor
Humidity
Imaging: Estimate biomass; greeness index for
Ambient Temp
fertilization; detect flowering; estimate yield.
Soil Moisture
Imaging constrained: Develop smarter portable
platforms.
Ontologies
Ontologies are a set of formalised terms that allow us to represent
knowledge about concepts and relationships in a domain.
Annotating with ontologies means describing a domain object or
process.
This image shows the wheat plant on
the left has increased “salt tolerance
(TO:0006001)”
Modelling with ontologies means classifying a domain object or
process, and its relationship to other domain concepts.
OBI:0000050 : “platform”
“A platform is an object_aggregate that is
the set of instruments and software needed
to perform a process. “
Ontologies
Evolutionary
Changes in Domain, Model & Data
Expressed in OWL (& RDF Schema)
Provides syntax & semantics - enables reasoning
Expressivity vs decidability
Validation via reasoning
Designed to be open & interoperable
Facilitates sharing, reuse & Integration
Maturing technology stacks
APIs, reasoners, triple stores, query engines

Putting the OD in PODD
Basics: Ontologies as domain models for research
data
Model domain objects as ontological objects
Base ontology: domain independent
Phenomics ontology: domain specific
Organizes data logically
Represented as metadata objects
