- Observation Genes PucDOPA5GT and PuB5GT were identified in Portulaca umbraticola.
- Intervention effect Simultaneous expression of PuDOD1, PuCYP76AD1 and PucDOPA5GT (or PuB5GT) leads to betacyanin accumulation.
- Intervention effect Co-expression of PuDOD1 and PuCYP76AD2 (or PuCYP76AD3) leads to betaxanthin accumulation.
- Mechanism PuCYP76AD3 contributes to betaxanthin biosynthesis but lacks 3,4-dihydroxy-L-phenylalanine oxidase activity.
- Association Most flower colour variation can be explained by the combined expression levels of these genes.
- Association Expression of betalain biosynthetic genes significantly influences flower colour in betalain-producing plants.
- Mechanism The basic betalain biosynthesis pathway is elucidated for the first time in Portulacaceae.
