Abstract

Faba beans (Vicia faba) have been grown for years and are a good crop for sustainable and diverse farming systems. With various cultivated forms such as broad, horse, tick, and central Asian varieties. Faba beans have a high nutritional value, often outperforming peas and certain grains. Their ability to thrive in diverse climates and soil types gives them a competitive edge over other legume crops. The limited use of these crops in modern agriculture is attributed to yield instability resulting from biotic and abiotic stresses, especially drought, which impacts cultivation in the Mediterranean region. Faba bean cultivation in Pakistan is limited due to farmers' awareness, seed accessibility issues, and insufficient research and development efforts for the crop successfully sequenced the vast faba bean genome, paving the way for breakthroughs in developing more nutritious, climate, biotic, and abiotic stress resilient legume. Despite its importance, the faba bean genome remains unannotated, and many gene families are yet to be characterized. This study compared the PR genes from Vicia faba and Medicago truncatula, using chromosomal mapping, motif, gene structure, phylogenetic, and synteny analyses to better understand evolutionary patterns and functional characteristics. The outcomes from this study provided insights into plant defense mechanisms and evolutionary processes that would be a valuable resource for crop improvement and stress resilience research.
