Taking the stress out of plant life

I heard a funny story from a biology teacher the other day. In a discussion about stress in plants a student says to the teacher “plants are rooted Miss”. The teacher looks a bit mortified and the student replies “they are rooted because they cant get up and move when they are under stress’

its stressful being a plant

Grain crops under stress – get this stuff off me

So loving this story shared with me yesterday Plants freak out  like animals when stressed. Extract

Both plants and animals produce a neurotransmitter known as GABA, which stands for gamma-aminobutyric acid. This acid is primarily produced when the organism is under stress: when it’s hungry, or scared, or exposed to pathogens or (in the case of plants) acidity or salinity.

What has only been suggested up until now is that the presence of this acid acts as a signal to tell the plant to behave in a certain way. That’s changed now. According to the authors of the ARC study, “We’ve discovered that plants bind GABA in a similar way to animals, resulting in electrical signals that ultimately regulate plant growth when a plant is exposed to a stressful environment.”

Breeding plants for stress reduction

With the help of farmer levies from the GRDC the CSIRO are breeding plants that are more stress and disease tolerant to help our grain farmers supply safe, affordable and nutritious food to Australian families
