Understanding the role of phytohormones in controlling heat stress tolerance during pollen development in wheat.

Abstract
Severe periods of high temperatures during sensitive stages of pollen development lead to male sterility in wheat. Phytohormones are known to be involved in pollen development, but their impact in mitigating heat stress has still yet to be investigated. This project aims to investigate the role of phytohormones in heat stress sensitivity and tolerance using a reverse genetics, molecular and biochemical approach.

| Description | We have discovered the hormone and genes which are involved in regulating pollen development in wheat and also how these change in response to heat stress. We have also produced the first auxin and ethylene hormone signalling mutants in wheat. These have been shown to show reduced tolerance to heat and defects in other developmental defects such as root growth. |
| Exploitation Route | Understanding more about the hormones involved in controlling pollen development and heat induced pollen abortion in wheat can pave the way for genetic changes and/or chemical application to reduce the loss of pollen viability and therefore yield in wheat as a result of heat stress. |
