Chinese bitter orange
Citrus trifoliata
Citrus trifoliata, also known as trifoliate orange or sour orange, is a traditional plant primarily associated with East Asia and has been used in various cultural practices. While its specific traditional uses are not well-documented, it has been utilized for ornamental purposes and as a rootstock for citrus grafting due to its pest resistance. Recent scientific research indicates that genome editing can modify the synthesis of bitter flavanones while preserving other beneficial flavonoids, enhancing salt tolerance and nitrogen use efficiency in this plant. Additionally, studies have shown that inoculation with Funneliformis mosseae can alter leaf sugar profiles under water stress conditions, suggesting potential applications in improving plant resilience. The safety profile for Citrus trifoliata appears to be favorable, with no major issues recorded. There are currently no known drug interactions reported for this plant.

What the science says
- Genome editing inactivated the 1,2RhaT gene, abolishing bitter flavanone synthesis while retaining health-benefitting flavonoids in citrus.
- The study found that the CtrNAC019-CtrNPF2.1 module enhances both chloride sequestration in vacuoles and nitrate efflux, improving salt tolerance and nitrogen use efficiency in Citrus trifoliata.
- The study identifies a regulatory module involving CtrCBL1/CtrCIPK6, CtrBBX32, and CtrZAT10 that controls cold-induced sugar accumulation in Citrus trifoliata roots.
- Inoculation with Funneliformis mosseae altered leaf sugar profiles and gene expressions in trifoliate orange under water stress conditions.
