In comparison to ordinary light sources, blue polarized light significantly altered the stem color, making it reddish. RNA-seq and targeted metabolomics analysis were used to investigate the mechanisms underlying the effects of the different light treatments on\n                      <jats:italic>D. officinale<\/jats:italic>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The results revealed that 2448, 2065, and 2763 genes and 1190, 812, and 958 metabolites were differentially expressed in the BP-B, BP-W and W-B comparisons, respectively. GO and KEGG analyses of the DEGs revealed that the most significant differences between\n                      <jats:italic>D. officinale<\/jats:italic>\n                      under polarized light and ordinary light sources were in pathways related to microtubules, UDP-glycosyltransferase activity and microtubule binding. Metabolome analysis revealed that the expression of melanoside A, 1-methyl-L-histidine, and rhapontigenin 3'-O-glucoside were the SCMs most strongly affected by blue polarized light. The use of bidirectional orthogonal partial least squares analysis revealed a significant transcriptome-metabolome correlation in the BP-W and BP-B comparisons. Joint analysis of DEGs and SCMs revealed significant differences between polarized and ordinary light sources, mainly in terms of plant hormone signal transduction, zeatin biosynthesis, phenylpropanoid biosynthesis, and flavonoid biosynthesis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>\n                      These results highlight that blue polarized light enhances flavonoid and phenylpropanoid metabolism, offering a strategy for improved secondary metabolite yield in\n                      <jats:italic>D. officinale<\/jats:italic>\n                      cultivation.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpls.2026.1717555","type":"journal-article","created":{"date-parts":[[2026,2,24]],"date-time":"2026-02-24T06:46:11Z","timestamp":1771915571000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Widely targeted metabolomic and transcriptomic analyses of the effects of blue polarized light and ordinary light on Dendrobium officinale"],"prefix":"10.3389","volume":"17","author":[{"given":"Hansheng","family":"Li","sequence":"first","affiliation":[{"name":"Fujian Provincial Key Laboratory of Bamboo Resources Development and Utilization, Sanming University","place":["Sanming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beibei","family":"Chen","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Bamboo Resources Development and Utilization, Sanming University","place":["Sanming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruichen","family":"Li","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Bamboo Resources Development and Utilization, Sanming University","place":["Sanming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haibin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Horticulture, Nanjing Agricultural University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Horticulture, Nanjing Agricultural University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gang","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Resources and Chemical Engineering, Sanming University","place":["Sanming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"085301","DOI":"10.1088\/1361-648X\/ad98db","article-title":"Manipulating floquet-driven topological insulator with off-resonant elliptically polarized light in presence of hexagonal Fermi surface warping","volume":"37","author":"Agrawal","year":"2025","journal-title":"J.
