Multimodal learning reveals plants' hidden sensory integration logic.

Area of Science:

• Plant biology
• Molecular plant-pathogen interactions
• Plant-microbe symbiosis

Background:

• Plants possess complex molecular networks for integrating environmental signals.
• The fundamental rules of plant sensory integration are not fully understood.
• Understanding plant-microbe communication is crucial for agriculture.

Purpose of the Study:

• To investigate how microbial effectors reprogram plant sensory systems.
• To uncover the mechanisms of plant-microbe communication during symbiosis.
• To identify novel integration hubs and molecular pathways involved in plant sensory perception.

Main Methods:

• Multimodal analysis of tomato roots interacting with fungal symbionts.
• Computational analysis to confirm experimental findings and reveal novel pathways.
• Investigation of transcriptional, metabolic, and phenotypic responses.

Main Results:

• Microbial effectors systematically reprogram plant sensory systems.
• Identified novel integration hubs where sensory pathways converge.
• Discovered mechanisms including rewiring of iron homeostasis and suppression of jasmonate defenses.
• Demonstrated isolation of nuclear splicing programs from metabolic noise.

Conclusions:

• Symbionts exploit latent hubs where sensory pathways converge for communication.
• Established a new paradigm for understanding plant-microbe communication.
• Provided fundamental insights into plant perception.
• Identified concrete targets for engineering stress-resilient crops.
