A betaxanthin-based visible and fluorescent reporter for monitoring plant transformation
Crop Journal, 2023 Commonly used reporters rely on a single property, such as the fluorescence of GFP and visible color of anthocyanins, therefore these reporters hardly handle the complicated condition in practice.

Betalain production is possible in anthocyanin-producing plant species given the presence of DOPA-dioxygenase and L-DOPA [PDF]
BMC Plant Biology, 2012 Background Carotenoids and anthocyanins are the predominant non-chlorophyll pigments in plants. However, certain families within the order Caryophyllales produce another class of pigments, the betalains, instead of anthocyanins.
