Engineered petunia emits a continuous green glow thanks to genes from a light-up mushroom.

Consumers in the United States can now pre-order a genetically engineered plant for their home or garden that glows continuously. At a base cost of US$29.00, residents of the 48 contiguous states can get a petunia (Petunia hybrida) with flowers that look white during the day; but, in the dark, the plant glows a faint green. Biotechnology firm Light Bio in Sun Valley, Idaho, will begin shipping a batch of 50,000 firefly petunias in April.

    Figure 1. Features of the fungal bioluminescence system. a. Spectrum of fungal bioluminescence (Neonothopanus nambi, in green) overlaid onto the absorbance spectrum of plant leaves (Nicotiana tabacum, in dark gray). b. The caffeic acid cycle shares metabolites with some of the major plant biosynthetic pathways. The fungal or plant origin of enzymes is indicated with mushroom and plantlet symbols, respectively. Abbreviations: 4CL — 4-coumarate:CoA ligase; C3H — p-coumaric acid 3-hydroxylase; C4H — cinnamic acid 4-hydroxylase; CCOMT — caffeoyl-CoA 3-O-methyltransferase; CCR — cinnamoyl-CoA reductase; CHI — chalcone isomerase; CHS — chalcone synthase; CPH — putative caffeoyl pyruvate hydrolase; H3H — hispidin-3-hydroxylase; HispS — hispidin synthase; Luz — luciferase; PAL — phenylalanine ammonia-lyase. Absorbance spectrum of leave is representative of experiment performed on three leaves. Luminescence spectrum is rendered from dataset published in Ref.

    Oh Luciferase, where have they put you now, my friend?
