Role of Altered Metabolites and Metabolic Pathways in Major Tuber Crops Under Drought Stress.

ABSTRACT: Drought stress poses a significant challenge to growth and productivity of major tuber crops, particularly cassava (Manihot esculenta Crantz), potato (Solanum tuberosum L.) and sweet potato (Ipomoea batatas (L.) Lam.). These crops are among the most widely cultivated tubers globally and play a critical role in food and nutritional security, especially in drought-prone regions of sub-Saharan Africa, Asia and Latin America. Several studies have highlighted that metabolites such as sucrose, proline and arginine contribute to osmotic adjustment, cellular protection and energy balance under drought stressed conditions. However, a comprehensive synthesis of drought-induced metabolic responses and associated pathways utilized by major tuber crops remains limited. Therefore, t
