Plants with genetically encoded autoluminescence

An Author Correction to this article was published on 04 June 2020

This article has been updated

Abstract

Autoluminescent plants engineered to express a bacterial bioluminescence gene cluster in plastids have not been widely adopted because of low light output. We engineered tobacco plants with a fungal bioluminescence system that converts caffeic acid (present in all plants) into luciferin and report self-sustained luminescence that is visible to the naked eye. Our findings could underpin development of a suite of imaging tools for plants.

Supplementary Figure 4. Bioluminescent Nicotiana tabacum and Nicotiana benthamiana plants.

a and b are photos of potted plants in ambient light and in the dark, respectively, captured on Sony Alpha ILCE-7M3 camera. Leaves marked with pink triangles on a, as well as control leaves from wild type plants, were then cut off and imaged in IVIS Spectrum CT in ambient light and in the dark separately for Nicotiana tabacum (c, d) and Nicotiana benthamiana (e, f). Black paper box around the control leaves visible on images c and e was used to prevent light emitted by transgenic plants from illuminating leaves of the control plants. All images correspond to a single experiment performed on three glowing and one wild-type Nicotiana tabacum, and three glowing and one wild-type Nicotiana benthamiana plants.

Nicotiana tabacum (a, b) and Nicotiana benthamiana (c, d) lines. a and c are photos in ambient light, b and d are photos in the dark. The black paper box around the control flowers visible on images a and c was used to prevent light emitted by transgenic plants from illuminating flowers of the control plants. All flowers depicted were randomly collected from different plants in a single imaging experiment (6 glowing and 3 wild-type Nicotiana tabacum, 6 glowing and 4 wild-type Nicotiana benthamiana plants).

a and b are images in ambient light and in the dark captured on IVIS Spectrum CT. c and d are images of the same flowers in ambient light and in the dark captured on Sony Alpha ILCE-7M3. On c and d, the flowers were imaged along with the calibrated light source XLS-4 that emits 1.6*109 photons/sec at 525 nm. This calibrated light source was separately imaged on IVIS Spectrum CT, see Figshare (doi: 10.6084/m9.figshare.11871888) for raw files. All the flowers were collected from different plants in a single imaging experiment (14 glowing Nicotiana tabacum, and 13 glowing Nicotiana benthamiana plants).

Data points are shown, Luminescence change is absolute change of signal (ΔL = luminescence after injection – initial luminescence). Strikethrough text highlights the absence of a compound in the mixture. Notably, only mixtures containing caffeic acid induced the increase of luminescence. The box extends from the lower to upper quartile values of the data, orange line represents the median. Whiskers represent a full data range. Groups containing multiple reagens (Kruskal-Wallis H Test, H-statistic=48.59, p=7.11e-10) and single potential reagents (Kruskal-Wallis H Test, H-statistic: 68.65, p=8.3e-15) were analyzed separately.

Circadian oscillations of luminescence. Photos of three plants were being captured constantly for ten days, in normal light conditions (17.5 h day; days 1-3 and 8-10) or in constant darkness (days 4-7). Each image of Plant 1 was compressed into a single vertical line of pixels to create the kymogram. The mean brightness of plants 1-3 is displayed on the graph. The graph on days 1-3 is representative of nine plants in three independent experiments. The full graph (days 1-10) shows the luminescence of three plants in a single experiment. Pseudocolor is used for visual clarity.

Supplementary Figure 16. Photos of cross-section of stem of a glowing Nicotiana tabacum plant in ambient light and in the dark.

(A) In ambient light. (B) in the dark.The robust light emission belongs to the cells of shoot pith parenchyma (in the center of the stem). Weaker bioluminescence is observed from core parenchyma cells (periphery of the stem). Maximal light intensity corresponds to the region of the axillary bud — newly forming meristem — and surrounding parenchymatous cells. Completely lignified tissues, xylem and phloem, with cambium in between, lack luminescence (visible at the right side of the stem as a dark band). The images are representative of two experiments with similar results.
