Site-specific cleavage of bacterial MucD by secreted proteases mediates antibacterial resistance in Arabidopsis

open access: yesNature Communications, 2019
During innate immune responses, plant cells secrete proteases into apoplastic spaces where they contribute to pathogen resistance. Here Wang et al. show that the Arabidopsis SAP1 and SAP2 proteases cleave the bacterial MucD protein to inhibit growth of ...

Targeted gene deletion with SpCas9 and multiple guide RNAs in Arabidopsis thaliana: four are better than two

open access: yesPlant Methods, 2023
Background In plant genome editing, RNA-guided nucleases such as Cas9 from Streptococcus pyogenes (SpCas9) predominantly induce small insertions or deletions at target sites.

Transcriptome Signatures in Pseudomonas simiae WCS417 Shed Light on Role of Root-Secreted Coumarins in Arabidopsis-Mutualist Communication

open access: yesMicroorganisms, 2021
Pseudomonas simiae WCS417 is a root-colonizing bacterium with well-established plant-beneficial effects. Upon colonization of Arabidopsis roots, WCS417 evades local root immune responses while triggering an induced systemic resistance (ISR) in the leaves.

Litterbox—A gnotobiotic Zeolite-Clay System to Investigate Arabidopsis–Microbe Interactions

open access: yes, 2020
Plants are colonised by millions of microorganisms representing thousands of species with varying effects on plant growth and health. The microbial communities found on plants are compositionally consistent and their overall positive effect on the plant ...

An EDS1 heterodimer signalling surface enforces timely reprogramming of immunity genes in Arabidopsis

open access: yesNature Communications, 2019
CC and TIR-domain type NLR receptors trigger plant immunity in response to pathogen effectors. Here, Bhandari et al. show that the EP-domain surface of EDS1 heterodimers signals downstream of both receptor types and ensures a rapid transcriptional ...

Rhizobacteria-Mediated Activation of the Fe Deficiency Response in Arabidopsis Roots: Impact on Fe Status and Signaling

open access: yesFrontiers in Plant Science, 2019
The beneficial root-colonizing rhizobacterium Pseudomonas simiae WCS417 stimulates plant growth and induces systemic resistance against a broad spectrum of plant diseases. In Arabidopsis thaliana (Arabidopsis), the root transcriptional response to WCS417

Natural history of Arabidopsis thaliana and oomycete symbioses [PDF]

open access: yes, 2008
Molecular ecology of plant–microbe interactions has immediate significance for filling a gap in knowledge between the laboratory discipline of molecular biology and the largely theoretical discipline of evolutionary ecology.

Bacteria-fungal Confrontation and Fungal Growth Prevention Assay

open access: yesBio-Protocol, 2018
There are some bacteria which can grow and multiply at the cost of living fungal biomass. They can potentially utilize fungi as a source of nutrients to forage over them.

Microbial interactions within the plant holobiont

open access: yesMicrobiome, 2018
Since the colonization of land by ancestral plant lineages 450 million years ago, plants and their associated microbes have been interacting with each other, forming an assemblage of species that is often referred to as a “holobiont.” Selective pressure ...
