Introduction

Cytochrome P450 family has been identified in all kingdoms of life, which can catalyze more than 20 types of reactions, including hydroxylation, epoxidation, cyclization, and so on [1]. One of its members, C3H, catalyzes the formation of caffeic acid from p-coumaric acid. This reaction is associated with lignin biosynthesis, which is vital for plant development [2]. Recently scientists have utilized Fungal Bioluminescence Pathway (FBP) to generate autoluminescent plant [3]. C3H, which produced the starting substance for caffeic acid cycle, is a crucial candidate gene for FBP genetical modification.

The engineering objective of this project is to generate brighter autoluminescent plants using synthetic biology approaches. Team BGI-MammothEdu-South 2024 selected a variety of candidate genes from different species and tested their functions in FBP via eGFP reporter system (pS1300-GFP plasmid). The NtC3H gene loci is LOC107803600, transcript loci is XM_016627348.1 (NCBI). Team BGI-MammothEdu-South 2024 extracted Nicotiana tabacum flower, leaf and stem total RNA, reverse transcribed into cDNA and cloned the NtC3H CDS with specific primer pairs.
