A complex microbial community comprising bacteria, fungi, and oomycetes is beneficial for plant growth. Inactivation of the plant innate immune system shifts this balance, making the fungal load a primary cause of disease. Bacterial partners residing in roots provide an additional layer of protection.
A new study explores how plants respond differently to useful and harmful microbes, revealing that accessory chromosomes from fungal strains dictate these responses. Most plant genes are expressed similarly in response to both beneficial and pathogenic fungi, but with key differences occurring just 12 hours after interaction.
A new viral disease caused by Tomato brown rugose fruit virus (ToBRFV) has emerged, threatening global tomato production. ToBRFV overcomes the durable Tm-2² resistance gene, which had remained unbroken for over half a century.
Researchers found that clover grown with symbiotic nitrogen-fixing bacteria in Martian regolith experienced significant 75% more root and shoot growth compared to uninoculated plants. However, the regolith showed no excess production of nitrogen compounds, suggesting a potential role for these microbes in terraforming Mars soils.
Researchers investigate Pseudomonas cannabina pv. alisalensis (Pcal) interaction with cabbage and oats, discovering coronatine (COR) suppresses salicylic acid to aid pathogen growth. This finding opens doors to new disease control strategies.
Scientists are still unraveling how pathogens adapt to changing conditions, including climate change and global trade. Genome sequencing and big data technologies have revealed that dramatic events like hybridization between pathogen species can lead to rapid evolution of virulence on new host plants.
Scientists found that rain-borne microbes can successfully colonize plants' aboveground microbial communities, protecting them from stressors. The study suggests that rain is a potentially important reservoir for phyllosphere bacteria, which could be used to improve plant health.
Researchers can leverage innovative technologies to analyze complex interactions within the plant root microbiome. By combining mesocosms with in-situ sensors and imaging tools, scientists can replicate experiments on spatial and temporal scales.
The New Roots for Restoration Biology Integration Institute aims to integrate plant traits, communities, and the soil ecosphere to advance restoration of natural and agricultural ecosystems. The project seeks to understand how root traits influence plant interactions with each other and with the soil.
Researchers at Rice University are developing novel computational approaches to track environmental microbiome dynamics over time, across species and after perturbations. The team will use biofilm-based 'species abundance networks' on scaffolds to observe how they form their own genome-exchange networks.
Plants use metabolites, chemical signals, and dual receptor recognition to distinguish beneficial microbes from pathogens. A plant cell follows a flowchart to determine the response needed based on microbe type and lifestyle.
Citrus disease-induced microbial shifts may lead to new management strategies for crops. Researchers found increased diversity in microbiome associated with Huanglongbing disease progression.
A recent focus issue explores the cell biology of virus-host and virus-vector interactions to improve crop management. Research reveals insights into plasmodesmatal connections, cell-cell signaling, and biotechnological approaches for host resistance.
Researchers found that strains predicted to be more sensitive to T6SS were able to coexist with aggressor strains, challenging the traditional assumption of a 'winner-take-all' result. The study suggests that genetics and environmental factors play a significant role in determining competition outcomes.
Researchers discovered that resistant poplar trees have higher levels of defense hormones and lower cytokinins. Hormone changes in response to insect feeding are also inherited, providing a model for pest management.
Current research in belowground botany is advancing our understanding of plant root systems, their structure, and function. New technologies like digital imaging of root traits are enabling scientists to study root systems more effectively.
Researchers aim to develop crops more resilient to climate change and emerging pathogens through microbial interactions. The Collaborative Crop Resilience Program will focus on three projects: Matrix, Interact, and InRoot, which examine plant-microbial interactions above ground and below ground, as well as the development of new crop v...
Researchers found that liverworts can be infected by Phytophthora palmivora and respond with proteins similar to those in flowering plants. The discovery reveals early land plants were genetically equipped to respond to microbial infections, indicating an ancient relationship between plants and microbes.
Researchers propose applying ecological theories to improve microbial technology development, aiming for more effective and sustainable agriculture. By identifying underlying ecological mechanisms, treatment communities can be designed to be robust and persistent.
Research reveals that herbivores can evade plant defenses by using symbiotic bacteria, while plants have two lines of defense against predators. Understanding these interactions may help control pests and improve plant productivity through probiotics.
The DOE JGI's 2012 Community Sequencing Program allocates over 30 trillion bases for researchers to study plant-microbe interactions and environmental genomics. This includes projects on rhizosphere microbial communities, Casuarina trees, and microbial communities in extreme environments.
The four-part PBS series 'Intimate Strangers: Unseen Life on Earth' delves into the importance of microbes in sustaining human life and driving chemistry of life. Dr. Frederic Pfaender, a UNC-CH microbiologist, advocates for watching the series to learn something and enjoy the experience.
The Microbe-Mineral Group at Virginia Tech aims to discover conditions under which microbes release nutrients or contaminants from mineral surfaces. Researchers hope to advance bioremediation and control unwanted releases of phosphorus and other minerals.
