Abstract

Re-engineering of transcriptional networks regulating secondary cell wall formation may allow the improvement of plant biomass in widely grown plantation crops such as Eucalyptus. However, there is currently a scarcity of freely available standardized biological parts (e.g., Phytobricks) compatible with Type IIS assembly approaches from forest trees, and there is a need to accelerate transcriptional network inference in nonmodel biomass crops. Here we describe the design and synthesis of a versatile three-panel biological parts collection of 221 secondary cell wall-related Eucalyptus grandis transcription factor coding sequences and 65 promoters that are compatible with GATEWAY, Golden Gate, MoClo, and GoldenBraid DNA assembly methods and generally conform to accepted Phytobrick syntaxes. This freely available resource is intended to accelerate synthetic biology applications in multiple plant biomass crops and enable reconstruction of secondary cell wall transcriptional networks using high-throughput assays such as DNA affinity purification sequencing (DAP-seq) and enhanced yeast one-hybrid (eY1H) screening.
