Plant interference

Investigating plant-plant interference by metabolic fingerprinting.

New analytical developments in post-genomic technologies are being introduced to the field of plant ecology. FT-IR fingerprinting coupled with chemometrics via cluster analysis is proposed as a tool for correlating global metabolic changes with abiotic or biotic perturbation and/or interactions. The current study concentrates on detecting chemical responses by inter-species competition between ...

Plant RNA interference in vitro.

Cross-interference of plant development and plant-microbe interactions.

Plant roots are host to a multitude of filamentous microorganisms. Among these, arbuscular mycorrhizal fungi provide benefits to plants, while pathogens trigger diseases resulting in significant crop yield losses. It is therefore imperative to study processes which allow plants to discriminate detrimental and beneficial interactions in order to protect crops from diseases while retaining the ab...

RNA Interference in Insect Vectors for Plant Viruses

Insects and other arthropods are the most important vectors of plant pathogens. The majority of plant pathogens are disseminated by arthropod vectors such as aphids, beetles, leafhoppers, planthoppers, thrips and whiteflies. Transmission of plant pathogens and the challenges in managing insect vectors due to insecticide resistance are factors that contribute to major food losses in agriculture....

Silencing of a plant gene by transcriptional interference

Integration of foreign DNA into eukaryotic genomes results frequently in a total or partial loss of gene function, caused by the interruption of indispensable structures of the gene itself. Using T-DNA insertions in Arabidopsis we screened for mutants with deregulated chlorophyll precursor accumulation in etiolated seedlings. A mutant designated rfd1 (red fluorescent in darkness) with increased...
