Endophytes Modulate Plant Genes: Present Status and Future Perspectives

Area of Science:

• Microbial Ecology
• Plant-Endophyte Interactions
• Genomics

Background:

• Endophytic microorganisms interact with plants in diverse ways, influencing plant health and function.
• These microbes produce metabolites that aid in competition and overcoming plant defenses.
• The concept of 'endobiomes' highlights the complex interplay between plants and their endophytic communities.

Purpose of the Study:

• To explore the poorly understood mechanisms by which endophytes modulate plant genomes.
• To investigate the impact of endophyte-plant interactions on host plant functioning and metabolism.
• To review recent advances and future challenges in understanding endophyte effects on host gene expression and resistance.

Main Methods:

• Literature review focusing on genomic and metabolic interactions between endophytes and host plants.
• Analysis of existing research on microbial quorum sensing and its role in endophyte-plant communication.
• Exploration of studies investigating endophyte-induced changes in host plant gene expression and metabolite profiles.

Main Results:

• Endophyte metabolites, regulated by quorum sensing, influence plant immunity and microbial competition.
• Endophyte-plant interactions can significantly alter host plant metabolism and gene expression.
• Genomic insights are crucial for understanding endophyte capabilities and their role in host adaptation.

Conclusions:

• Further genomic research is essential to elucidate endophyte mechanisms and their impact on host plants.
• Endophytes offer a promising avenue for enhancing plant growth, health, and resistance to environmental challenges.
• Understanding endophyte-host interactions is key to developing sustainable agricultural strategies.
