Profiles: Ma et al. (2023) · Sample values, gene IDs and source checksums (JSON). Candidate annotations require functional validation.
Nervonic acid (cis-15-tetracosenoic acid) is a very-long-chain monounsaturated fatty acid. Its 24-carbon structure makes it relevant to studies of fatty-acid elongation in oil-accumulating seeds.
Acer truncatum seed lipid profiles provide a system for examining how fatty acids accumulate during development. Combined RNA-seq, Ribo-seq and proteomic measurements can help identify candidates for further study in lipid metabolism. Ma et al. (2023).
Compare measured sample profiles for selected seed lipid-pathway candidates and use the expression patterns to plan functional experiments.
The pathway and co-expression views support candidate prioritization. Gene annotation and expression correlation alone do not establish enzyme substrate specificity, regulatory interactions or effects on seed oil composition.

Suggestive associations for 10 fatty-acid traits in Acer palmatum (Apal), with candidate-gene annotations. The SNP table uses P < 1 × 10⁻⁵. This Oil page presents Acer truncatum data; the GWAS cohort is a separate dataset.
Data source: Ma et al. (2023), BMC Biology. The sample-profile download provides gene IDs, sample labels and source checksums. Follow each chart's source and measurement labels when interpreting its values.

PC = phosphatidylcholine. The dashed PC connector summarizes acyl exchange; intermediate steps are omitted. References: elongation cycle · PC desaturation.
Seed fatty-acid composition across six developmental stages, from Ma et al. (2020), The Plant Journal. Hover for values; click legend entries to toggle.
DAF = days after flowering. Values follow the source's percentage scale. Five values are stated exactly in the text (tooltip: "reported"); the remaining points were read from the published Figure 4b and are approximate to about ±0.3 percentage points (tooltip: "read from Figure 4b"). Fatty acids were undetectable at 70 DAF and nervonic acid at 85 DAF (shown as 0); a few small 85–100 DAF values could not be read from the figure and are left blank.
log₂(FPKM+1) profiles for three seed samples at 85 DAF (CK: A-7-7, C-7-7, D-7-7) and three at 115 DAF (T: A-8-19, C-8-19, D-8-19). RNA-seq and Ribo-seq runs are paired by BioSample in PRJNA877423. Ratios use log₂((Ribo FPKM+1)/(RNA FPKM+1)) and are descriptive; differential translation is not inferred. Missing measurements remain unavailable.
Pearson correlations on untransformed Acer truncatum RNA FPKM (6 samples; |r| ≥ 0.85; 57 edges among 20 selected genes). Date and A/C/D series may drive these unadjusted associations; edges do not establish regulation. Drag nodes, hover for r, or click for details.
