- Abstract
- Climate change is expected to bring rising temperatures and reduced rainfall, imposing multiple stresses on agricultural systems. Expanding food sources by incorporating underutilized crops, such as pseudocereals, could help mitigate these challenges while improving food security. Among them, buckwheat (Fagopyrum esculentum and Fagopyrum tataricum) and amaranth (Amaranthus cruentus) are gaining attention for their nutritional and medicinal benefits. However, the physiological mechanisms underlying their resistance to heat, drought, and salinity remain largely unexplored. Another promising approach to enhancing crop resilience involves leveraging wild relatives as sources of stress-resistant genes. Within the tomato clade, Solanum chilense stands out due to its high genetic variability and remarkable tolerance to extreme environments. To assess its potential in tomato breeding, we compared the resistance of cultivated tomato (Solanum lycopersicum) and S. chilense to heat, drought, and salinity stress while also investigating reproductive barriers to facilitate hybridization. These strategies, combining orphan crops and wild genetic resources, offer promising avenues for developing climate-resilient agriculture.
