How to use this

This is a T-DNA binary vector for Agrobacterium-mediated transformation of C. frutescens. Path from this package to a living plant:

1
Transform Agrobacterium
Introduce the construct into Agrobacterium tumefaciens (strain GV3101 or LBA4404) by electroporation or freeze-thaw.
2
Inoculate pepper explants
Co-cultivate with leaf discs or cotyledon sections from C. frutescens seedlings at the 4–6 leaf stage.
3
Select on nptII (kanamycin resistance)
Non-transformed tissue will not survive. Run selection on MS medium at conditions specified in the protocol.
4
Screen regenerants by PCR
Use the integration confirmation primers from the CRISPR guide designs file to verify cassette insertion before advancing to T1 generation.
5
Grow out and measure
Advance confirmed transgenic lines to fruit-bearing stage. Confirm capsaicinoid content by HPLC or capsaicin-specific colorimetric assay.

Take it further with CRISPR

The CRISPR guide designs in this package are ready to use with Cas9 or Cpf1 for precision integration at defined genomic loci — and for disrupting competing pathway enzymes that reduce capsaicinoid yield. For site-specific insertion, pathway stacking, or multiplexed editing across pepper cultivars, the guides are your starting point.

Work with Scoville Splice

This construct is a research tool. What it can become is an ingredient.

Scoville Splice works with food and beverage companies to take engineered capsaicinoid constructs from sequence to supply chain. If you’re developing a product — a sauce, a seasoning, a functional food — and you need a precise, consistent heat profile that no natural pepper can deliver, that’s what we were built for. We offer custom cultivar development, strain characterization, pilot-scale grow protocols, and formulation consulting.
