Abstract excerpt

Oxygen (O2) availability in plant tissues is dynamically shaped by photosynthesis and respiration and is linked to stress responses and development. While mitochondria are the primary consumers of cellular O2, their impact on chloroplast functions under low-oxygen conditions remains insufficiently understood. Mitochondrial retrograde signaling activates expression of nuclear genes encoding alternative oxidases...
