Deep Learning-Driven Protein Design for Maize Improvement: AI-Guided Solutions for Sustainable Agriculture

Bridging AI, Synthetic Biology, and Crop Science to Address Global Food Security.

This presentation explores the transformative potential of AI-driven protein design in revolutionizing maize (corn) breeding. Learn how deep learning models like AlphaFold, ESMFold, and RFdiffusion enable rapid engineering of stress-resilient proteins for:

Disease resistance (e.g., fungal pathogens like Fusarium and Puccinia)

Drought and heat tolerance (synthetic transcription factors for root and stomatal optimization)

Nutrient efficiency (engineered phosphate/nitrogen transporters)
Enhanced photosynthesis (AI-designed carbonic anhydrases)

Key highlights:

Case studies from Cell, Science, and Nature Biotechnology (2023–2024) showcasing AI-designed proteins validated in field trials.

Ethical considerations and future directions for AI-guided CRISPR integration in crop improvement.

Visual summaries of protein structures, field data, and AI workflows.

Target audience: Plant scientists, agronomists, bioinformaticians, AI researchers, and students in biotechnology and agriculture.

2. Protein Design in Crop Science Protein engineering enables the creation of novel enzymes, transporters, and regulatory proteins critical for stress tolerance and nutrient uptake (Jumper et al., 2 021) Limitations of traditional methods: Random mutagenesis and directed evolution are time-consuming (Arnold, 2023) Only ~10% of designed proteins show desired activity experimentally (Hie et al., 2023) AI-driven solutions: Deep learning reduces design cycles from months to days (e.g., RFdiffusion; Watson et al., 2023)

3. What is Deep Learning? Deep learning is a type and subset of machine learning that uses artificial neural networks to learn from data. Artificial neural networks are inspired by the human brain, and they can be used to solve a wide variety of problems, including image recognition, natural language processing, and speech recognition. It focuses on utilizing neural networks to perform tasks such as classification, regression, and representation learning.
