Gene ID	Name	Evidence / Role	Function (this paper)
Mp3g11100	MpC3H	experimental subject	Sole M. polymorpha CYP98 (3'-hydroxylase of the phenylpropanoid pathway), stated as Mapoly0037s0087. Unlike tracheophyte CYP98 enzymes, which prefer 4-coumaroyl esters, it prefers 4-coumaroyl amides, a major functional difference between bryophyte and vascular-plant CYP98. Expression is highest in archegoniophores and antheridiophores.
Mp6g00020	MpC4H1	experimental subject	CYP73 cinnamate 4-hydroxylase confirmed by heterologous expression to 4-hydroxylate trans-cinnamate. MpC4H1 is the most highly expressed of the three isoforms, especially in thalli, antheridiophores and archegoniophores.
Mp8g05070	MpC4H2	experimental subject	CYP73 cinnamate 4-hydroxylase with confirmed C4H activity in heterologous assays. One of three functional M. polymorpha CYP73 isoforms characterised alongside Anthoceros and Physcomitrium enzymes.
Mp8g05080	MpC4H3	experimental subject	CYP73 cinnamate 4-hydroxylase with confirmed C4H activity in heterologous assays. Selected for characterisation as one of eight M. polymorpha CYP73 candidates retaining the conserved motifs.
