Abstract
Long-term field monitoring of leaf pigment content is informative for understanding plant responses to environments distinct from regulated chambers but is impractical by conventional destructive measurements. We developed PlantServation, a method incorporating robust image-acquisition hardware and deep learning-based software that extracts leaf color by detecting plant individuals automatically. As a case study, we applied PlantServation to examine environmental and genotypic effects on the pigment anthocyanin content estimated from leaf color. We analyzed >4 million images of small individuals of four Arabidopsis species in the field, where the plant shape, color, and background vary over months. Past radiation, coldness, and precipitation significantly affected the anthocyanin content. The synthetic allopolyploid A. kamchatica recapitulated the fluctuations of natural polyploids by integrating diploid responses. The data support a long-standing hypothesis stating that allopolyploids can inherit and combine the traits of progenitors. PlantServation facilitates the study of plant responses to complex environments termed “in natura”.
Methods
Top-view images of Arabidopsis were collected multiple times per day using commercial RGB cameras in a common garden in Japan for three seasons.
Labelling data were generated by manually marking the areas of target plants in images.
Scripts were produced for analyzing the images and color and size information of the target plants extracted from the images.
Usage notes
Labelling data (.json files) can be opened using labelme in python.
R scripts (.r files) can be opened in R or as a text file.
Python scripts (in script_7_for_Dataset_8_Fig_S29) can be opened in Python or as a text file.
