Genetic improvement of legume roots for adaption to acid soils

The Crop Journal, Journal Year: 2023, Volume and Issue: 11(4), P. 1022 - 1033

Published: May 20, 2023

Acid soils occupy approximately 50% of potentially arable lands. Improving crop productivity in acid soils, therefore, will be crucial for ensuring food security and agricultural sustainability. High soil acidity often coexists with phosphorus (P) deficiency aluminum (Al) toxicity, a combination that severely impedes growth yield across wide areas. As roots explore the nutrients water required plant development, they also sense respond to below-ground stresses. Within terrestrial context widespread P Al toxicity pressures, plants, particularly roots, have evolved variety mechanisms adapting these legumes, soybean (Glycine max) plants may acquire nitrogen (N) through symbiotic fixation (SNF), an adaptation can useful mitigating excessive N fertilizer use, either directly as leguminous participants rotation intercropping systems, or secondarily green manure cover crops. In this review, we investigate especially soybean, recent advances our understanding root-based linked root architecture modification, exudation symbiosis, together associated genetic molecular strategies individual and/or interacting conditions soils. We propose breeding legume cultivars superior nutrient efficiency tolerance traits selection might become powerful strategy producing varieties capable maintaining improving yields more stressful subjected increasingly challenging environmental conditions.
