Transcription factor-mediated cell-to-cell signalling in plants

Area of Science:

• Plant Biology
• Cell Signaling

Background:

• Plant cells use mobile transcription factors for intercellular communication.
• These factors are crucial for plant organ development and responding to environmental stimuli.

Purpose of the Study:

• To review current knowledge on non-cell-autonomous transcription factors in plants.
• To integrate discoveries on their evolution, trafficking, and role in signaling networks.

Main Methods:

• Literature review of recent studies on mobile transcription factors.
• Analysis of proposed mechanisms for plasmodesmata trafficking.
• Integration of findings from diverse omics approaches.

Main Results:

• Non-cell-autonomous transcription factors are key regulators of plant organ formation.
• Plasmodesmata play a critical role in controlling transcription factor trafficking.
• Mobile transcription factors interact with other signaling molecules, creating complex networks.

Conclusions:

• Mobile transcription factors are vital components of plant intercellular signaling.
• Understanding their regulation and trafficking is essential for deciphering plant development and responses.
