Rubber Biosynthesis Focus

A pathway-centered entry for MVA/MEP, IPP/DMAPP, prenyl donors, CPT/CPTL, REF/SRPP, latex/root-associated and terpenoid candidate genes.

This topic is built from precomputed GFF/GO/KEGG/homology candidate sets and linked evidence from expression, proteome, localization, Pfam, Swiss-Prot, PPI, coexpression and TFBS modules. Results are candidate evidence, not experimental validation.

The current database contains 5523 candidate records, 4979 candidate genes, and 8 pathway steps; the main display is centered on the TK1151 reference while OH-1004/LXL04 remains queryable and linked.

Cross-species Research Reference

8 reference genes are counted separately from rubber-dandelion candidates. They are literature, omics, or sequence resources from Para rubber tree, guayule, a related dandelion, and Eucommia; external function or homology is not direct validation in rubber dandelion.

1. Choose a speciesClick a species card or use the filter to focus on one reference species and material context.
2. Read the evidence typeRead the evidence and boundary column: direct experiments, omics associations, and sequence resources have different interpretation ranges.
3. Verify the sourceEach DOI, article, or public database entry is clickable; download the current filter for further comparison.
Eucommia records are a trans-polyisoprene comparator only and are excluded from natural cis-rubber candidate and pathway-card counts.

Evidence Boundary

Current results integrate annotation, GO/KEGG, homology, predicted localization, domains, expression/proteome and network evidence. High/Medium/Low indicates evidence density and consistency, not experimental validation.
