Regulation of tomato fruit growth and development during different plant developmental stages by far-red light: a combined anatomical, physiological, and transcriptomic analysis.

ABSTRACT: Far-red (FR) light, a critical environmental signal perceived via phytochrome photoreceptors, modulates numerous aspects of plant development; yet, its role in reproductive processes such as fruit growth and ripening remains less clear. In this study, we investigated the developmental stage-specific effects of FR light on fruit development, anatomy, and metabolism in dwarf tomato (Solanum lycopersicum) plants. FR light was applied during three distinct stages: vegetative phase, early fruit development, and late fruit development. Three corresponding plant batches were analyzed: (i) full-growth cycle plants for final fruit weight and plant architecture, (ii) plants harvested at the mature green stage for anatomical measurements, and (iii) plants during early fruit formation for integrated t
