Plant Genetics as a Tool for Manipulating Crop Microbiomes: Opportunities and Challenges

Area of Science:

• Agricultural Science
• Microbiome Research
• Plant Genetics

Background:

• Sustainable agriculture faces challenges from population growth and climate change.
• Microbiomes significantly impact plant health, driving interest in microbiome manipulation.
• Current methods like inoculation have limited success in complex agricultural settings.

Purpose of the Study:

• To explore host plant genetic manipulation as a novel strategy for microbiome engineering.
• To review how crop domestication and breeding have influenced plant microbiomes.
• To assess the potential of conventional breeding and genetic engineering for improving plant-microbiome interactions.

Main Methods:

• Review of existing literature on host genetic control of plant microbiomes.
• Analysis of domestication and breeding impacts on crop-associated microbial communities.
• Discussion of genetic engineering and conventional breeding approaches for microbiome modulation.

Main Results:

• Domestication and breeding have altered crop microbiomes, presenting opportunities for manipulation.
• Host plant genetics play a crucial role in shaping the associated microbiome.
• Genetic engineering and breeding offer pathways to enhance beneficial plant-microbiome interactions.

Conclusions:

• Genetic manipulation of host plants presents a promising alternative for microbiome engineering in agriculture.
• Understanding host genetic control is key to developing effective microbiome-based sustainable agriculture strategies.
• Further research is needed to overcome challenges in applying host genetics for microbiome management.
