A precise spacing between the NPA domains of aquaporins is essential for silicon permeability in plants.
TLDR
It is discovered that Si absorption is exclusively confined to species that possess NIP-III aquaporins with a GSGR selectivity filter and a precise distance of 108 amino acids (AA) between the asparagine-proline-alanine (NPA) domains.
Identification and functional characterization of silicon transporters in soybean using comparative genomics of major intrinsic proteins in Arabidopsis and rice
TLDR
Comparative analysis of MIPs in plants provides opportunities to decipher gene evolution, functionality and selectivity of nutrient uptake mechanisms, and exploit the identification and functional characterization of Si transporters to optimize the benefits that plants can derive from Si absorption.
Silicon-mediated resistance of Arabidopsis against powdery mildew involves mechanisms other than the salicylic acid (SA)-dependent defence pathway.
TLDR
The results indicate that Si contributes to Arabidopsis defence priming following pathogen infection, but highlight that Si will confer protection even when priming is altered, concluding that Si-mediated protection involves mechanisms other than SA-dependent defence responses.
Silicon enhances the accumulation of diterpenoid phytoalexins in rice: a potential mechanism for blast resistance.
TLDR
The results of this study strongly suggest that Si plays an active role in the resistance of rice to blast rather than the formation of a physical barrier to penetration by M. grisea.
Phenolic compounds that confer resistance to spruce budworm
TLDR
The results suggest that the two phenolic compounds reduce the pressure of spruce budworm herbivory on specific host tree phenotypes, reflecting a strategy of constitutive resistance in P. glauca.
Milsana-induced resistance in powdery mildew-infected cucumber plants correlates with the induction of chalcone synthase and chalcone isomerase
TLDR
These results are the first to link CHS and CHI increased activities with induced resistance in cucumber and highlight the implication of flavonoids in the complex defence system of this plant species.
Analysis of aquaporins in Brassicaceae species reveals high-level of conservation and dynamic role against biotic and abiotic stress in canola
TLDR
This first in-depth characterization of Brassicaceae AQPs highlights transport mechanisms and related physiological processes that could be exploited in breeding programs of stress-tolerant cultivars and supports their role in stress alleviation.
The Transition from a Phytopathogenic Smut Ancestor to an Anamorphic Biocontrol Agent Deciphered by Comparative Whole-Genome Analysis[W][OPEN]
TLDR
Interestingly, the biocontrol agent appears to have acquired genes encoding secreted proteins not found in the compared Ustilaginales, including necrosis-inducing-Phytophthora-protein- and Lysin-motif- containing proteins believed to have direct relevance to its lifestyle.
Insertional Mutagenesis of a Fungal Biocontrol Agent Led to Discovery of a Rare Cellobiose Lipid with Antifungal Activity
TLDR
Insertional mutagenesis was applied for the first time to a fungal biocontrol agent, Pseudozyma flocculosa, in an attempt to obtain mutants with altered antagonistic properties via DNA-mediated transformation, and multiple copies of the plasmid were integrated in tandem at one to many chromosome loci.
Effects of milsana and benzothiadiazole on the ultrastructure of powdery mildew haustoria on cucumber.
ABSTRACT Disease assessments and cytological investigations provided valuable information on the modes of action and efficacies of two prophylactic compounds, Milsana and benzothiadiazole (BTH),
