The principal signal molecule involved in induced systemic resistance in plants is
Mechanistically, plant biotechnology involves photosynthetic engineering and nutrient pathways support biofortification. This validates Jasmonic acid because it supports metabolic engineering in crops, a pattern repeatedly demonstrated in plant biology research.
Ref: Taiz et al., Plant Physiology and Development, 6th Edition, Chapter 7, Photosynthesis, discusses light reactions, Calvin cycle and metabolic engineering examples like Golden Rice providing insight into plant biotechnology.
