Phyllosphere microbiomes uncovered: Research trends, geographic disparities, and key microbial players

科学分野:

• Microbiology
• Plant Science
• Ecology

背景:

• The phyllosphere microbiome, communities on plant surfaces, is crucial for plant health.
• Understanding research trends and knowledge gaps is essential for advancing phyllosphere studies.

研究 の 目的:

• To systematically review and analyze current research trends in phyllosphere microbiome studies.
• To identify knowledge gaps, common methodologies, and dominant microbial taxa.

主な方法:

• Systematic literature review of 333 reports from Web of Science.
• Inclusion criteria: original research on phyllosphere microbiomes using next-generation sequencing.
• Data extraction from 268 eligible reports published between 2009 and March 2025.

主要な成果:

• Above-ground phyllosphere research (375 studies) is significantly less explored than below-ground (1562 studies).
• A notable scarcity of studies originates from the Southern Hemisphere.
• Dominant bacterial and fungal taxa in the phyllosphere were identified.

結論:

• The phyllosphere microbiome field requires increased focus on above-ground plant tissues.
• Future research should aim to address geographical biases and explore underrepresented regions.
• Recommendations for future research directions are provided based on identified trends and gaps.
