• Harnessing foliar-applied melatonin to improve yield and stress tolerance in tomato (Solanum lycopersicum L.) under deficit irrigation (2026) · Frontiers in Plant Science · doi

  While this study demonstrates clear benefits for the ‘Alisa’ cultivar, further research is needed to evaluate the cultivar- dependent variability in MT responsiveness across the diverse genetic spectrum of tomato. In addition, further research is needed to elucidate the specific molecular and metabolic pathways under- lying in MT-mediated drought tolerance and to explore its integration with plant nutrition strategies for sustainable crop management.

• Exploring genetic variability, heritability and genetic advance in hybrids of tomato in Trans-Gangetic Plains region (2026) · Plant Science Today · doi

  The lack of sufficient genetic variability and effective selection of desirable quantitative traits hinders breeding programmes. - The use of low-yielding cultivars and susceptibility to diseases and insect pests are major challenges in tomato production.

• Genetic dissection of cold stress tolerance and yield potential under cold stress in nested synthetic wheat (Triticum aestivum L.) introgression libraries using multi-locus genome-wide association and haplotype analysis (2026) · Functional & Integrative Genomics · doi

  Further study is needed to validate the identified genetic factors and to develop cultivars with improved cold stress tolerance and yield potential. - The use of genome-wide association and haplotype analysis can be applied to other crops to improve their stress tolerance and yield potential.
