Integrated transcriptome and metabolome analysis reveals the impacts of prolonged light exposure on starch and protein content in maize kernels.
Article in BMC genomics, 2025. 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
backgroundThe light environment significantly influences crop growth, development, quality, and yield, particularly in controlled-environment agriculture. Recent advances in artificial lighting technology have allowed growers to precisely control the light environment in terms of duration, spectrum, and intensity. Starch and protein are the most significant nutritional constituents of maize kernels. However, little is known about the effects of the light environment on starch and protein content in maize kernels. Therefore, we investigated the effects of natural light and supplemental exposure to blue (B), far-red (FR), and red (R) light on starch and protein content in kernels of the inbred maize line B73.
resultsExposure to supplemental B, FR, or R light resulted in significant increases in starch content but decreases in protein content. Notably, protein content was lowest under B light. Substantial proportions of genes (5.03-75.23%) and metabolites (46.89-85.64%) were regulated by different wavelengths of light. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, as well as weighted gene co-expression network analysis (WGCNA), revealed that differentially expressed genes (DEGs) under B, FR, and R light were involved in pathways related to starch and protein synthesis. KEGG metabolomic analysis showed that differentially abundant metabolites (DAMs) were primarily associated with histidine, D-amino acid, cysteine, and methionine metabolism. Nine DEGs related to starch synthesis were identified as potential candidates for investigating the effects of light quality on starch synthesis, and 14 DEGs related to protein synthesis provided evidence for the influence of light quality on protein synthesis in maize.
conclusionsThis study identified the regulatory network governing starch and protein content in B73 maize kernels under different light conditions, contributing to a deeper understanding of how light quality affects the nutritional components of maize kernels.
