PubMedAgarwood — one of the world's most expensive natural fragrances used in perfumes and incense — is increasingly rare due to overharvesting, and this discovery could help farmers grow better-rooted, more productive agarwood trees without waiting decades for nature to do the work.
Agarwood trees naturally produce a precious resin used in luxury perfumes and traditional medicine, but getting trees to make it reliably is tricky. Researchers found a tiny protein that, when added to the tree, makes it grow stronger roots and produce new fragrant molecules it doesn't normally make. This could be a game-changer for farmers trying to cultivate agarwood sustainably instead of harvesting wild trees.
Key Findings
The antisense-derived peptide anti-AsWOX11 significantly enhanced adventitious root growth in Aquilaria sinensis (agarwood tree) compared to untreated plants.
Treatment induced production of two novel volatile compounds — α-gurjunene and α-cedrene — not previously associated with this pathway, expanding the tree's fragrance profile.
Transcriptomic and proteomic analyses confirmed the peptide modulates hormone signaling networks involved in both root development and secondary metabolite biosynthesis simultaneously.
chevron_right Technical Summary
Scientists discovered that a small protein derived from a gene's 'antisense' strand can boost root growth and trigger production of rare fragrant compounds in agarwood trees, opening a new path for sustainable agarwood farming.
Abstract Preview
Although WUSCHEL-related homeobox (WOX) 11-mediated regulation of adventitious root growth is well-established, the functional significance of antisense transcripts remains incompletely elucidated....
