2. Overview • Problem: Soybean and flood stress
• Our solution
• Value Proposition/Competitive advantages
• Potential applications
• Market overview
• Intellectual property status
• Competing solutions
• Partnering information
3. Flood
Stress
Lower
YieldSoybean and flood stress
Damaged roots: inadequate water and nutrient
Poor symbiotic nitrogen fixation
Accumulation of toxic compounds
Favorable conditions for plant diseases
Non-stressed
4. • Soybean is particularly sensitive to flooding
• As short as 2 days of waterlogging cause 27% yield reduction and >70%
reduction for longer period of waterlogging.
• <10% current varieties showed moderate tolerance to waterlogging.

5. Increased tolerance to other abiotic stresses
Our solution
A novel trait for soybean flood tolerance:
Small Auxin Upregulated Protein_Flooding
Tolerance (SAUR_FT) gene
Improved waterlogging tolerance
Yield increased up to 55%
Nutrient deficiencyDrought
6. Value Proposition/Competitive advantages
• Increase tolerance to abiotic stresses, such as
flooding/waterlogging, drought, and nutrient
deficiency.
• Increase yield of crops under stress and non-stress
conditions.
• Increase soybean production and food security
across the world

7. Potential applications
• Can be incorporated into high value soybean varieties by marker-
assisted breeding
• Can be edited to create a improved allele of the SAUR_FT by genome-
editing, such as CRISPER/Cas9
• Can be modified and inserted into other crops such as rice, corn,
beans, alfalfa, and lentils
8. Market overview: Soybean Production Market
(Transparency Market Research)
• 2017: US $146.23 billion
• >2500 varieties in many sizes, shapes, and colors
• Total soybean biotech traits value at $13 billion in 2017
• 2025: US $215.746 billion
• Increasing market value while
each new trait can be
incorporated into multiple
varieties

regulators
Auxin or synthetic
auxin derivatives
12. Developmental Stages
Discovery of
the new traits
Proof-of-Concept:
Enhanced flood tolerance confirmed
Enhanced drought tolerance confirmed
Further Progress:
Incorporated the natural
tolerant allele into an elite
line from Mizzou
On-going:
Integrating the traits into soybean
plants under field trials
Next:
Transfer new alleles into
designated elite
background by MAS
On-going:
Confirm tolerance to other
abiotic stresses such as
nutrient deficiency stress
Next:
Create a new allele conferring improved effect
in root system and stress tolerance

Flooding stress reduces gas exchange between plants and the atmosphere, because oxygen diffuses more than 10 000 times more slowly in water than in air. The resulting decrease in oxygen concentration leads to impaired mitochondrial oxidative phosphorylation in plant cells and a corresponding decrease in ATP (Yin et al., 2014)
