Tiers
Six engineering tiers of difficulty, from native Capsicum peppers (Pepper) up to the Tier 5 frontier. Pick a tier to see every product at that difficulty.
Pepper
20030–3.3MSHU
Native Capsicum cultivars — directed-evolution and promoter-swap edits to the host pathway, zero heterologous genes.
1 organism
Tier 1
60150–1.4MSHU
Low-hanging fruit: Solanaceae relatives with 88–92% synteny. 4–5 heterologous genes, 18–24 months to first fruit.
3 organisms
Tier 2
4330–224.5KSHU
Extended nightshades and Physalis — 5–7 heterologous genes, 82–86% synteny, 24–36 months.
4 organisms
Tier 3
37030–861.2KSHU
Cross-family engineering across Rosaceae, Cucurbitaceae, Asteraceae. 7–10 heterologous genes, 36–48 months.
28 organisms
Tier 4
26230–861.2KSHU
Frontier: full synthetic pathway in evolutionarily distant hosts. 10–12 heterologous genes, 48–72 months.
24 organisms
Tier 5
6530–586.4KSHU
Reserved — longest-horizon targets with fundamentally alien secondary metabolism and extreme transformation challenges.
