John Jifon

Dr. John Jifon is a Professor in the Department of Horticultural Sciences at Texas A&M AgriLife Research and Extension Center. His research examines environmental stress physiology in plants, focusing on mechanisms of tolerance to drought, temperature extremes, and nutrient imbalances affecting photosynthetic efficiency and crop quality.

Research integrates measurements across biological scales from leaf biochemistry to stand-level productivity. Key themes include optimizing water/nutrient use efficiency, assimilate partitioning, and developing strategies to enhance productivity under environmental constraints.

His investigations encompass:

• Drought response mechanisms in bioenergy crops
• Metabolomic profiling of fruit quality traits
• Soil-plant-microbe interactions
• Bioenergy crop performance under marginal conditions
• Virus-host interactions in horticultural crops

Recent publications reflect diverse methodological approaches including metabolomics, soil science, plant pathology, and crop physiology. Studies frequently employ multi-location trials to assess genotype × environment interactions in specialty and bioenergy crops.

Current projects focus on sustainable bioenergy production systems, drought resilience in sugarcane, and quality optimization in melon breeding programs. Research outputs contribute to improved crop management strategies for water-limited environments.
