Our Vision

What we wanted to see with our project

In New Zealand, 91% of kiwifruit growers cite winter temperatures as the greatest threat to crop yield. Source: Cradock-Henry, N. (2017).

Cold temperatures can stunt growth, cause severe plant damage, and even kill growing plants, making them a severe risk to the industry that needs to be addressed.

Our vision is to have crop plants that do not require these costly interventions in order to be protected from winter temperatures.

We hope that in time farmers will not fear the oncoming of winter, or have their livelihood threatened by a sudden frost. Genetic engineering provides an avenue for this.

Frost resistance genes, in the form of Ice Recrystallisation Inhibition Proteins and Antifreeze Proteins are well documented in many species, both plants and animals and can be used to protect crop plants from the kind of damage caused by cold without the need for other interventions.

We hope to improve crop yields, therefore reducing waste and making better use of the farmland that is in current use. We hope to make it possible to grow crops in colder, or more unstable environments than it is currently possible to do, thorough improving cold tolerance of these plants.

In all, we hope to lift many of the limitations imposed upon crop farmers by cold winter temperatures.

Current methods of frost protection are expensive and labour intensive. Current methods include:

- Selective Breeding

- Frost Covers

- Fans and Helicopters

- Sprinkler Systems

- Heaters and Candles

These, among other techniques employed, are highly costly and only reduce the damage done as well as only ‘saving’ some of the crop.
