ローレンス・バークレー国立研究所の研究チームは、植物と微生物の相互作用を高い再現性で解析するため、自律型実験システム「EcoBOT」を開発した。植物―微生物研究では、実験者による水やりやサンプリング、環境管理のばらつきが結果に影響しやすいことが課題となっていた。EcoBOTは、ロボットによる灌水、培養管理、画像取得、サンプル採取などを自動化し、温度や湿度などの環境条件を厳密に制御することで、長期間にわたり標準化された実験を実現する。これにより、植物の成長や根圏微生物群集の変化を高精度かつ再現性良く比較でき、実験の効率と信頼性が大幅に向上する。さらに、大量のデータ取得にも対応し、AIやデータ解析との組み合わせによる植物・微生物相互作用の解明や、作物の生産性向上、炭素循環、持続可能な農業技術の開発への応用が期待される。研究チームは、EcoBOTを植物科学分野の共通研究基盤として活用し、研究成果の比較や共同研究を促進したいとしている。

Abstract

Introduction:
Advances in automation and AI/ML offer new opportunities for plant science, including design, modeling, and analysis. This study aimed to develop an automated platform for researching small model plants under axenic conditions and integrate it with AI/ML tools.

Methods:
The EcoBOT platform was developed, which consists of sterile containers (EcoFABs) for growing plants and imaging for monitoring plant growth and health. Brachypodium distachyon was grown on the EcoBOT, and its response to nutrient limitation and copper stress was evaluated.

Results:
The results showed that Brachypodium distachyon grown in the EcoBOT maintained sterility and responded to nutrient limitation and copper stress. Analysis of over 6,500 root and shoot images revealed varying sensitivity and response rates to copper. Bayesian Optimization was used to improve model accuracies relating copper concentrations to plant biomass via sequential experiments, resulting in a >30% improvement.

Discussion:
The findings of this study demonstrate the potential of the EcoBOT platform for researching plant responses to environmental factors. Future experiments could focus on relating other chemical stresses and microbial interactions to create generalized models of plant responses.

Abstract

Hyperspectral imaging provides a powerful tool for analyzing above-ground plant characteristics in fabricated ecosystems, offering rich spectral information across diverse wavelengths. This study presents an efficient workflow for hyperspectral data segmentation and subsequent data analytics, minimizing the need for user annotation through the use of ensembles of sparse mixed scale convolution neural networks. The segmentation process leverages the diversity of ensembles to achieve high accuracy with minimal labeled data, reducing labor-intensive annotation efforts. To further enhance robustness, we incorporate image alignment techniques to address spatial variability in the dataset. Downstream analysis focuses on using the segmented data for processing spectral data, enabling monitoring of plant health. This approach provides a scalable solution for spectral segmentation, and facilitates actionable insights into plant conditions in complex, controlled environments. Our results demonstrate the utility of combining advanced machine learning techniques with hyperspectral analytics for high-throughput plant monitoring.
