Cinnamate-4-hydroxylase is a key enzyme in lignin synthesis which plays an important role in plant tolerance to heavy metal stress. In this study, a cinnamate-4-hydroxylase gene named RsC4H was cloned from the leaves of Rhizophora stylosa by homologous cloning and rapid amplification of cDNA ends (RACE). Bioinformatics analysis showed that the full length of RsC4H gene cDNA was 2006bp, the length of open reading frame was 1572bp, and encoded 523 amino acids. The relative molecular weight of the encoded protein is 60.18kD. It is a hydrophilic unstable protein with secondary structure alpha-helix (47.42%) and random coil (32.70%), this protein contains a transmembrane structure at the N-terminal and C-terminal, respectively, and does not contain signal peptides. It is mainly distributed on the membrane structure or endoplasmic reticulum to function, and belongs to P450 superfamily. RsC4H protein has high similarity with C4H protein of other plants. The phylogenetic tree results showed that it was closer to Cucurbita maxima (xp_023007159.1) and Cucurbita moschata (xp_022947682.1). qRT-PCR results showed that Rhizophora stylosa could quickly respond to heavy metal stress, improve the expression of RsC4H gene, promote lignin production, increase cell wall thickness and prevent metal ions from entering cells. The results enrich the gene pool of mangrove plants resistant to heavy metal stress, and lay a foundation for revealing the mechanism of heavy metal stress tolerance of mangrove at the molecular level.
