Great — below is a practical, lab-ready R&D protocol outline for organogenesis & micropropagation of Manila Elemi (Canarium luzonicum), prepared for COPI. It’s structured so your R&D team can immediately convert sections into SOPs and experiments (no waiting required). I’ve included recommended media/PGR ranges, critical controls, an experiment matrix, QA assays, and R&D milestones. Where helpful I cite primary and relevant literature (see inline citations).

COPI R&D Protocol Outline —

0 — Project goals (R&D deliverables)

Establish a reproducible direct & indirect organogenesis pipeline for Canarium luzonicum (shoot regeneration from leaf/stem/explant). (Putz Agarwood Farm)
Produce true-to-type, disease-free plantlets for CAPI plantations and germplasm conservation. (ScholarSpace)
Develop protocols for scale-up (temporary immersion systems, automated vessels) and cryopreservation of elite lines. (MDPI)

1 — Overview & Rationale

Canarium spp. (pili / elemi relatives) have been approached successfully with seed/seedling culture and there is precedent from Burseraceae and resinous trees for both organogenesis and somatic embryogenesis; key variables to test are explant type, basal medium, cytokinin:auxin balance, and light/temperature regimes. Use published tissue-culture strategies as starting points. (ScholarSpace)

2 — Materials & Core equipment (minimum)

Laminar flow hood, autoclave, culture room with controlled light (16/8 h) and 24±2 °C.
Sterile forceps, scalpels, inoculation tools.
Growth rooms and acclimatization greenhouse (mist/fog).
Media prep: MS basal salts, B5 vitamins (optional), agar, sucrose, gelling agents.
PGRs: BAP, TDZ, Kinetin, NAA, IAA, IBA, 2,4-D.
Antibiotics/antifungals for contamination experiments (e.g., cefotaxime, carbenicillin, fungicide stock).
Analytical: stereoscope, balance, freezer, GC-MS access for chemotype QC. (PMC)

3 — Explant sources & handling

Explant candidates (priority order):

Immature zygotic embryos (highest totipotency).
Shoot apices / nodal segments (direct organogenesis).
Young mature leaves (indirect organogenesis via callus).
Cotyledonary nodes / petiole sections.

Collection & transport: collect early morning; surface dry, transport in chilled sterile bags; process within 24 h. Use reproductive/juvenile tissues where possible—they give better regeneration. (ScholarSpace)

4 — Surface sterilization (starting protocol — optimize)

Wash explants under running water 20–30 min with Tween 20 (0.1% v/v).
In hood: 70% ethanol quick dip (30 s).
1.5–2.5% sodium hypochlorite (NaOCl) with a drop Tween 20 for 8–12 min for leaves; for embryos use gentler 0.5–1.0% and shorter exposure.
Rinse 3–5 × sterile distilled water.
Optionally a 0.1% HgCl₂ step for 2–3 min for recalcitrant contamination (use only under strict safety protocols and local rules).
Record contamination rates by explant type and sterilant exposure to build an SOP. (PMC)

5 — Basal media & standard recipe

Start point (per L): Murashige & Skoog (MS) salts + full strength (or ¾ for recalcitrant explants), MS vitamins, 30 g sucrose, 7–8 g agar, pH 5.7 before autoclave.
Alternate: Woody Plant Medium (WPM) or half-strength MS for woody species — include as comparisons in the experiment matrix. (PMC)

6 — Organogenesis strategies & recommended experimental matrices

A — Direct organogenesis (shoot induction from nodal/shoot apices)

Media baseline: MS + 0.5–2.0 mg/L BAP (or Kinetin) ± 0.1 mg/L NAA.
Alternative cytokinin: TDZ at 0.01–0.5 mg/L (powerful, but watch for hyperhydricity).
Light/temp: 16/8 h photoperiod; 24±2 °C.
Expected outcome window: 4–8 weeks for shoot primordia (optimize).

Test matrix example (n = 3 replicates × 10 explants each):

BAP: 0.5, 1.0, 2.0 mg/L (with 0.1 mg/L NAA)
TDZ: 0.01, 0.05, 0.1 mg/L (no auxin & with 0.05 mg/L NAA)
WPM vs MS

Measure: % explants forming shoots, mean shoots/explant, shoot length.

B — Indirect organogenesis (callus → shoot)

Callus induction: MS + 2,4-D (0.5–2.0 mg/L) ± BAP (0.5–1.0 mg/L).
Callus maintenance: dark or low light for 2–4 weeks, subculture every 3–4 weeks.
Shoot induction from callus: transfer to MS + BAP 1.0–3.0 mg/L ± low auxin (0.05–0.1 mg/L NAA).
Notes: monitor for friable, embryogenic callus vs compact non-morphogenic callus.

C — Somatic embryogenesis (if pursued)

Use immature zygotic embryos; induce with 2,4-D (1.0–3.0 mg/L) + BAP low; then gradual reduction of auxin and transfer to embryo maturation medium with ABA (0.5–1.0 mg/L) for cotyledon formation. Somatic embryogenesis protocols vary by species — run parallel trials. (MDPI)

7 — Shoot elongation & rooting

Elongation: after shoot induction, transfer to elongation medium: MS + lower cytokinin (BAP 0.1–0.5 mg/L) or cytokinin-free with gibberellic acid (GA₃ 0.1–0.5 mg/L) to promote stem elongation.

Rooting: MS half-strength or WPM with auxins:

IBA: 0.5–3.0 mg/L (pulse dip rooting also effective — 50–500 mg/L IBA quick dip)
NAA: 0.1–1.0 mg/L as alternative
Monitor root number, length, and quality over 2–6 weeks.

8 — Acclimatization (hardening)

Gently wash agar from roots under sterile water.
Transfer to sterile potting mix (peat : perlite : compost 1:1:1).
Place under high humidity (mist chamber / covered trays) for 7–14 days; gradually reduce RH over 2–4 weeks.
Move to greenhouse shadehouse before full field transfer. Record survival % at 2 and 8 weeks.

9 — Scale-up considerations

Move promising lines to temporary immersion systems (TIS) for proliferation (RITA® / twin-flask) to increase shoot numbers and reduce hyperhydricity.
Test bioreactor liquid culture for embryogenic cultures.
Implement automation for subculture intervals to reduce labor. (MDPI)

10 — Quality control, genetic fidelity & phytochemical QC

Genetic fidelity: use molecular markers (SSR, AFLP) on representative regenerants vs mother plant to check clonal fidelity.
Pathogen testing: screen for endophytes, viruses (if relevant) before field deployment.
Chemotype profiling: GC-MS profiling of essential oil from regenerants and mother trees (especially important if selecting for resin/aroma traits). (PMC)

11 — Experimental design & success metrics

Phase 1 (0–6 months): Sterilization optimization & explant screening. Success metric: ≥50% contaminant-free cultures from chosen explant.
Phase 2 (6–12 months): PGR matrix experiments for shoot induction. Metric: ≥60% explants producing ≥2 shoots/explant.
Phase 3 (12–18 months): Rooting & acclimatization optimization. Metric: ≥70% acclimatized plantlets.
Phase 4 (18–36 months): Scale-up (TIS) & pilot planting; GC-MS chemotype concordance with donor trees. (Adjust timelines per lab capacity.)

(Use the percentages above as R&D targets — adapt to real results.) (ScholarSpace)

12 — Troubleshooting common problems

High contamination: increase sterilant contact time, use explants from greenhouse (less field microbes), add antibiotic/antifungal in initiation medium (transiently).
Hyperhydricity (vitrification): reduce cytokinin (esp TDZ), increase gelling agent concentration, improve gas exchange.
Non-morphogenic callus: change auxin:cytokinin ratio; test different auxins (2,4-D vs picloram).
Poor rooting: use IBA pulses, lower salt strength, add activated charcoal to adsorb inhibitory phenolics.

13 — Safety, biosafety, and compliance

Hazard management for HgCl₂ and PGRs; proper waste disposal.
Conserve genetic resources ethically; obtain permits for collecting wild germplasm; respect FPIC where indigenous lands are involved. (STII)

14 — Data recording & SOPs to create immediately

Sterilization log (explants, batch, contamination %).
Media prep log & batch traceability.
Culture observation sheet (dates, callus/shoot events).
QC sheet for molecular & GC-MS results.
Create these SOP templates in the first 2 weeks of lab work.

15 — Suggested initial experiment matrix (practical)

Explants: immature embryo, shoot apex, young leaf (3 types).
Basal media: MS, ¾ MS, WPM.
Callus induction: 2,4-D 0.5, 1.0, 2.0 mg/L × BAP 0, 0.5, 1.0 mg/L.
Shoot induction: BAP 0.5, 1.0, 2.0 mg/L ± NAA 0.05 mg/L; TDZ 0.01, 0.05 mg/L tests.
Rooting: IBA 0.5, 1.0, 2.0 mg/L; half-strength MS.
Run factorial design where possible; use 10 explants × 4 replicates per treatment for statistical power.

16 — R&D milestones & resources (high level)

Month 0–3: Facility setup, SOP templates, explant collection plan.
Month 3–9: Sterilization + explant trials; initial PGR screens.
Month 9–18: Optimize organogenesis & rooting; pilot acclimatization.
Month 18–30: Scale-up in TIS; genetic/chemical QC; produce 100s of plantlets for pilot planting. (PMC)
