, a bulbous flower known for its showy bracts, is widely used around the world as a cut flower, potted, and garden plant. Besides its ornamental value, this species is rich in terpenoid metabolites and could serve as a resource for essential oils. Here, we report a chromosome-level genome assembly of and describe its biosynthetic pathways for anthocyanins and terpenoids.

- An 888-bp full-length cDNA gene encoding ascorbate peroxidase (APX) was cloned from the plant Anthurium andraeanum, named AnAPX, which has a significant similarity to APX genes from other plants.
- The AnAPX gene shows consistent expression across different plant parts and is particularly up-regulated when exposed to cold stress, suggesting its role in the plant's cold tolerance.
- Overexpressing AnAPX in tobacco plants led to decreased cell damage during cold exposure, indicating that this gene helps protect plants from chilling stress.
Background: Anthurium andraeanum is one of the most popular tropical flowers. In temperate and cold zones, a much greater risk of cold stress occurs in the supply of Anthurium plants. Unlike the freeze-tolerant model plants, Anthurium plants are particularly sensitive to low temperatures.
