Interactions between metabolism and chromatin in plant models

Area of Science:

• Plant biology
• Epigenetics
• Metabolism

Background:

• Epigenetic regulation enables rapid adaptation to environmental changes, crucial for sessile plants facing climate fluctuations.
• Environmental cues induce epigenetic changes like chromatin modifications, impacting plant acclimation and defense, though mechanisms remain unclear.
• The interplay between epigenetics and metabolism is an emerging area offering new insights into these processes.

Purpose of the Study:

• To review the connections between plant metabolism and chromatin modifications (histone acetylation, methylation, DNA methylation).
• To compare plant epigenetic-metabolism links with mammalian systems.
• To investigate the role of reactive oxygen species (ROS) and nitric oxide (NO) in modulating metabolic pathways and chromatin modifications.

Main Methods:

• Literature review focusing on plant and mammalian epigenetics and metabolism.
• Analysis of the role of ROS and NO in stress responses and epigenetic modulation.
• Comparative analysis between plant and mammalian systems.

Main Results:

• Plants and mammals share reliance on metabolic intermediates for chromatin modification.
• Plant-specific DNA methylation pathways are sensitive to folate metabolism.
• ROS and NO are identified as critical signaling molecules in environmental stress responses, fine-tuning epigenetic processes.

Conclusions:

• Metabolism and chromatin modification are intricately linked in plants, influencing adaptation to environmental stress.
• ROS and NO act as key mediators, connecting metabolic status to epigenetic dynamics during stress.
• Understanding these interactions is vital for plant acclimation and defense strategies.
