Thriving in a salty future: morpho-anatomical, physiological and molecular adaptations to salt stress in alfalfa (Medicago sativa L.) and other crops
AbstractBackground. With soil salinity levels rising at an alarming rate, accelerated by climate change and human interventions, there is a growing need fo
🌱 Soil salinity is rising rapidly, driven by climate change and human activity. Alfalfa, a perennial leguminous crop, shows promise as a sustainable solution to this challenge, but can modern varieties adapt to saline soils? (2/7)
🧬 Alfalfa is traditionally seen as moderately salt-tolerant. But new varieties show specific mechanisms that could make it a key crop for saline environments. These mechanisms are crucial for enhancing agricultural sustainability. (3/7)
🧪 Salinity impacts plants by causing osmotic stress, ion toxicity, and secondary stress. Alfalfa’s complex genome and out-crossing nature complicate genetic studies, but it also offers a wide range of adaptive strategies. (4/7)
🌿 Alfalfa adapts by changing its root system, regulating hormones to maintain ion balance, and using specialized metabolite profiles. This resilience allows it to manage salt stress while maintaining crucial rhizobia associations. (5/7)
