Effects of supplementary light treatment on saffron: integrated physiological, metabolomic, and transcriptome analyses.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSaffron (Crocus sativus L.) is a perennial, bulbous flower whose stigma is one of the most valuable spices, herbal medicines, and dyes. Light is an essential environmental regulator of plant growth, development, and metabolism. With the popularization of customized light-emitting diode (LED) light sources in facility agriculture, accurate light control has become essential for regulating crop yield and quality. In this study, white, red, and blue LED lights were applied to extend the photoperiod at the start and end of the day during the indoor stage of saffron cultivation. We investigated saffron growth and flowering using non-target metabolomic and transcriptome analyses to determine the flux and accumulation of metabolites from the stigma under different light treatments.
resultsThe results revealed that supplemental red and white lights both promoted dry mass accumulation in the stigma, with the optimal appearance achieved using white light. Supplemental white light promoted saffron flowering, whereas supplemental blue light delayed it. Supplemental blue light promoted crocin-1 and crocin-3 accumulation, whereas supplemental red light promoted crocin-2 accumulation. Expression analysis of key genes and their correlations with crocin-related metabolites may provide useful information for screening functional genes involved in crocin synthesis.
conclusionsThis study provides useful information for future application of LED light to improve the planting technology, quality, and yield of saffron, and reveals underlying molecular information for the further research.
