STARSEED provides quantitative and visual insights into changes that occur in root architectures across experimental treatments.Conclusion STARSEED can be easily generalized to other plants and provides insight into root system architecture development and response to varying growth conditions not captured by existing root architecture metrics and models. The code and data for our experiments are publicly available: https://github.com/GatorSense/STARSEED.Competing Interest StatementThe authors have declared no competing interest. ER -
