Transcriptome profiling reveals GABA role in alleviating chilling injury in Pitaya through regulation of phenylpropanoid pathways, antioxidant defense, and phytohormone signaling
This study investigated the effect of GABA on mitigating CI in pitaya fruit during cold storage for 6 weeks. The results showed that GABA treatment significantly reduced CI symptoms, decay incidence, and levels of malondialdehyde, superoxide anion and hydrogen peroxide compared to the control
