Alternaria alternata is a moderate, naturally occurring endophytic and wound-colonizing fungus that can play a supportive role in agarwood (Aquilaria spp.) resin induction systems when used carefully and only within a balanced consortium.
Below is a clear, agarwood-specific profile, aligned with professional, controlled induction programs such as your BarIno™ biotic and hybrid lines.
1. Basic Profile
- Kingdom: Fungi
- Phylum: Ascomycota
- Growth form: Dark (dematiaceous) filamentous fungus
- Pigmentation: Brown to black spores and hyphae
- Natural habitat: Plant surfaces, leaves, woody tissues, air
2. Role in Agarwood Formation
In Aquilaria trees, Alternaria alternata acts as a low-to-moderate biotic stress signal that:
- Colonizes wound margins and outer xylem
- Causes oxidative and cellular stress
- Triggers localized defense responses
- Supports resin spread and boundary definition
👉 As with all agarwood fungi, the resin is produced by the tree, not the fungus.
3. Why Alternaria Is Used
Strengths
- Mild, controllable stress
- Low tree mortality risk when dosed correctly
- Enhances resin uniformity, not just intensity
- Useful in young to mid-aged trees
- Complements stronger fungi by “rounding out” the response
Limitations
- Weak inducer if used alone
- Resin may be lighter if over-dominant
- Must be paired with stronger triggers
4. Best Use Strategy (Industry Practice)
Alternaria alternata performs best when:
- Used as a support fungus in a consortium
- Combined with:
- Primary inducers (Fusarium, Lasiodiplodia)
- Maturation fungi (Phaeoacremonium)
- Applied at lower density around wound perimeters
This supports:
Controlled stress → even resin spread → healthier trees
5. Functional Role in BarIno™ Systems (Suggested)
| Function | Role |
|---|---|
| Support inducer | Resin spread & stabilization |
| Stress level | Mild–moderate |
| Placement | Outer xylem / peripheral holes |
| Products | MycoResin Harmonia™, FusaTrinity™ |
Tagline concept:
“Shaping the resin response—gently and evenly.”
6. Culturing Notes (High-Level, Safe)
- Grows on PDA, rice, organic substrates
- Moderate growth speed
- Lower contamination risk than Aspergillus
- Requires clean but manageable handling
(Exact culturing parameters should remain proprietary.)
7. Safety & Compliance
- Common plant-associated fungus
- Some strains produce secondary metabolites
- Not edible; not for open release
- Should be deployed only under controlled inoculation protocols
8. Farmer-Simplified Explanation
“This fungus helps the resin spread slowly and evenly around the wound. It supports stronger fungi but does not damage the tree when used correctly.”
9. Consortium Synergy (Simple View)
| Fungus | Main Job |
|---|---|
| Fusarium spp. | Start resin signaling |
| Lasiodiplodia theobromae | Strong trigger |
| Alternaria alternata | Spread & balance |
| Penicillium spp. | Support & boundary |
| Phaeoacremonium parasiticum | Deep resin maturation |
10. Positioning Summary (One Line)
Alternaria alternata is best positioned as a resin-balancing support fungus, improving uniformity, spread, and tree survival in professional agarwood induction systems.
