Molecular Responses of Red Ripe Tomato Fruit to Copper Deficiency Stress

Fruit nutritional value, plant growth, and yield can be compromised by deficient copper (Cu) bioavailability, which often appears in arable lands. This condition causes low Cu content modifications the ripening-associated processes tomato fruit. research studies transcriptomic changes that occur red ripe fruit grown under suboptimal conditions to shed light on molecular mechanisms underlying this stress. Comparative RNA-sequencing functional analyses revealed deficiency during cultivation activates signals for metal ion transport, cellular redox homeostasis, pyridoxal phosphate binding, amino acid metabolism while repressing response starvation harvested Transcriptomic highlighted a number of novel stress-responsive genes unknown function indicated homeostasis regulation may involve additional components than those described model plants. It also studied high-affinity transporters well-known ripening depending availability, allowed potential candidates targeted biotechnological improvements reproductive tissues. We provide first study characterizing responses stress any crop.
