Water shortage is a significant threat to agricultural productivity all over the world.

Durum wheat is an important staple food crop for ensuring food security in the Mediterranean area, which is increasingly subjected to periods of severe drought due to global changes.

The characterization of root system architecture helped our understanding of the morphological responses of wheat plants to drought. Our findings demonstrated that drought exposure for 7 days significantly impacted the ionomic profiles of most genotypes in both shoot and root tissues, albeit to varying degrees.

It is also important to understand how micronutrients interact with each other and with macronutrients.

Therefore, it remains unclear whether the allocation of NSC to storage and defence molecules is at the expense of plant growth, especially in annual or short-lived flowering plants.

The results show that some of the desi genotypes and drought and heat stress tolerant genotypes accumulated greater NSC, proline or antioxidant enzymes and produced higher biomass and seed yield than kabuli and sensitive genotypes under stress. This is new evidence to support the view that plants accumulate NSC and secondary metabolites and grow at the same time under drought and heat stress conditions which implies complementary allocation of C to growth and defence metabolism.
