Molecular signatures that translate across omics layers and crops under high aluminium and low phosphorus stress facilitate the identification of reliable molecular targets for genotyping in lentil.

Aluminium toxicity and phosphorus deficiency are co-existing characteristics of low pH stress that significantly affect the grain yield of crops. The increasing acidity of Indian soils potentially limits the cultivable area for lentil (Lens culinaris), the third most widely consumed pulse. Breeding for tolerance requires an understanding of interdependent biological responses, but the molecular characterization of integrated tolerance remains elusive.
