Journal Article Nature plants · September 2024 Over the past three decades, researchers have isolated plant mutants that show constitutively activated defence responses in the absence of pathogen infection. These mutants are called autoimmune mutants and are typically dwarf and/or bearing chlorotic/nec ... Full text Cite

A critical role of a eubiotic microbiota in gating proper immunocompetence in Arabidopsis.

Journal Article Nature plants · September 2023 Although many studies have shown that microbes can ectopically stimulate or suppress plant immune responses, the fundamental question of whether the entire preexisting microbiota is indeed required for proper development of plant immune response remains un ...

Phyllosphere Microbiome.

Journal Article Annual review of plant biology · May 2023 The aboveground parts of terrestrial plants are colonized by a variety of microbes that collectively constitute the phyllosphere microbiota. Decades of pioneering work using individual phyllosphere microbes, including commensals and pathogens, have provide ... Full text Cite

Increasing the resilience of plant immunity to a warming climate.

Journal Article Nature · July 2022 Extreme weather conditions associated with climate change affect many aspects of plant and animal life, including the response to infectious diseases. Production of salicylic acid (SA), a central plant defence hormone1-3, is particularly vulnera ... Full text Cite

FERONIA restricts Pseudomonas in the rhizosphere microbiome via regulation of reactive oxygen species.

Journal Article Nature plants · May 2021 Maintaining microbiome structure is critical for the health of both plants and animals. By re-screening a collection of Arabidopsis mutants affecting root immunity and hormone crosstalk, we identified a FERONIA (FER) receptor kinase mutant (fer-8) with a r ... Full text Cite

Peat-based gnotobiotic plant growth systems for Arabidopsis microbiome research.

Journal Article Nature protocols · May 2021 The complex structure and function of a plant microbiome are driven by many variables, including the environment, microbe-microbe interactions and host factors. Likewise, resident microbiota can influence many host phenotypes. Gnotobiotic growth systems an ... Full text Cite

A plant genetic network for preventing dysbiosis in the phyllosphere.

Journal Article Nature · April 2020 The aboveground parts of terrestrial plants, collectively called the phyllosphere, have a key role in the global balance of atmospheric carbon dioxide and oxygen. The phyllosphere represents one of the most abundant habitats for microbiota colonization. Wh ... Full text Open Access Cite

Formation and exudation of non-volatile products of the arabidiol triterpenoid degradation pathway in Arabidopsis roots.

Journal Article Plant signaling & behavior · January 2017 Triterpenoids produced by plants play important roles in the protection against biotic stress. Roots of Arabidopsis thaliana produce different triterpenoids, which include the tricyclic triterpene diol, arabidiol. In a degradation reaction induced by infec ... Full text Cite

In planta variation of volatile biosynthesis: an alternative biosynthetic route to the formation of the pathogen-induced volatile homoterpene DMNT via triterpene degradation in Arabidopsis roots.

Journal Article The Plant cell · March 2015 Plant-derived volatile compounds such as terpenes exhibit substantial structural variation and serve multiple ecological functions. Despite their structural diversity, volatile terpenes are generally produced from a small number of core 5- to 20-carbon int ... Full text Cite

Analysis of diterpenes and triterpenes from plant foliage and roots.

Journal Article Methods in molecular biology (Clifton, N.J.) · January 2014 Terpene specialized metabolites exhibit multiple functions in plant-environment interactions and plant development. Molecular biologists investigating the biochemistry and molecular function of terpenes need to apply robust but yet sensitive analytical met ... Full text Cite

The major volatile organic compound emitted from Arabidopsis thaliana flowers, the sesquiterpene (E)-β-caryophyllene, is a defense against a bacterial pathogen.

Journal Article The New phytologist · March 2012 Flowers have a high risk of pathogen attack because of their rich nutrient and moisture content, and high frequency of insect visitors. We investigated the role of (E)-β-caryophyllene in floral defense against a microbial pathogen. This sesquiterpene is a ... Full text Cite

The biochemistry of homoterpenes--common constituents of floral and herbivore-induced plant volatile bouquets.

Journal Article Phytochemistry · September 2011 Volatile organic compounds emitted by plants mediate a variety of interactions between plants and other organisms. The irregular acyclic homoterpenes, 4,8-dimethylnona-1,3,7-triene (DMNT) and 4,8,12-trimethyltrideca-1,3,7,11-tetraene (TMTT), are among the ... Full text Cite

Variation of herbivore-induced volatile terpenes among Arabidopsis ecotypes depends on allelic differences and subcellular targeting of two terpene synthases, TPS02 and TPS03.

Journal Article Plant physiology · July 2010 When attacked by insects, plants release mixtures of volatile compounds that are beneficial for direct or indirect defense. Natural variation of volatile emissions frequently occurs between and within plant species, but knowledge of the underlying molecula ... Full text Cite
