Glutamate decarboxylase (GAD) is a small family in peach genome.
- class="label">•
The GAD gene expression is activated in response to hypoxia.
- class="label">•
Exogenous GABA application is able to modify the transcriptional activity of different GADs.

GABA application has no evident effect on Prunus rootstock tolerant to hypoxia.
