Insights into the ascorbate-glutathione cycle and methylglyoxal detoxification systems during leaf yellowing of macadamia

Puntos clave

• Leaf yellowing correlates with reduced efficiency of the ascorbate-glutathione cycle, indicating a deficiency in detoxification processes.
• Methylglyoxal levels increase significantly during leaf yellowing, suggesting a role in oxidative stress responses in macadamia.
• Observational analysis identifies key metabolic pathways affected by leaf yellowing, emphasizing the interaction of detoxification systems.
• These findings highlight potential intervention points for improving plant resilience against environmental stressors.
