(Submitter supplied) DICER-like proteins produce small RNAs that silence genes involved in development and defenses against viruses and pathogens. Which DCLs participate in plant-herbivore interactions remains unstudied. We identified four distinct DCL genes and stably silenced their expression by RNAi in Nicotiana attenuata, a model system for the study of plant-herbivore interactions. Silencing DCL1 expression was lethal to the plants. more...

(Submitter supplied) Piriformospora indica, an endophytic fungus of Sebacinales, colonizes the roots of many plant species including Arabidopsis thaliana. The symbiotic interaction promotes plant per-formance, growth and resistance/tolerance against abiotic and biotic stress. We demonstrate that exudated compounds from the fungus activate stress and defense responses in the Arabidopsis roots and shoots before the two partners are in physical contact. more...

(Submitter supplied) Fatty acid-amino acid conjugates (FACs) in the oral secretion (OS) of the Manduca sexta larvae are necessary and sufficient to elicit the herbivory-specific responses in Nicotiana attenuata, an annual wild tobacco species. We used SuperSAGE combined with 454 sequencing to quantify the early transcriptional changes elicited by the FAC N-linolenoyl-glutamic acid (18:3-Glu) in N. attenuata. The second fully expanded leaf of rosette stage plants were wounded by rolling a fabric pattern wheel three times on each side of the midvein and the wounds were immediately supplied with either 20 uL of 0.02% (v/v) Tween-20/water (solvent control) or 10 uL of synthetic N-linolenoyl-glutamic acid (18:3-Glu; 0.03 nmol/µL in 0.02% (v/v) Tween-20/water). more...

(Submitter supplied) The fungal mutualist Piriformospora indica is colonising barley roots thereby mediating various beneficial effects to its host. The interaction is characterised by an initial biotrophic interaction stage which is followed by a cell death-dependent colonisation phase. We used microarrays to identify the global programme of gene expression during the colonisation process of barley roots by P. indica and to obtain informations into plant defense and metabolic reprogramming.

(Submitter supplied) The root-colonizing endophytic fungus Piriformospora indica promotes root and shoot growth of its host plants. We show that growth promotion of Arabidopsis leaves is abolished when the seedlings are grown on media with nitrogen (N) limitation. The fungus neither stimulated the total N content nor did it promote 15NO3- uptake from agar plates to the leaves of the host under N-sufficient or N-limiting conditions. more...

(Submitter supplied) Microarray experiments were performed on the roots and leaves samples seperately using custom based Nimblegen platform (12plex). This is a time-course study. The plants were grown in controlled growth chamber condiditons. The seeds were sown in sterile petri plates with modified half-strength MS agar medium. The seedlings were then aseptically transferred into sterile polycarbonate container with half-strength MS liquid medium. more...

(Submitter supplied) Microarray experiments were performed on the roots and leaves samples seperately using custom based Nimblgen platform (12plex). This is a time-course study. The plants were grown in controlled growth chamber condiditons ambiient to soybean growth and development using a hydrophonics system. The tissues were harvested after 30days of growth in six time points- 0min, 30mins, 1hour, 2hours, 3hours and 5hours of dehydration.

(Submitter supplied) The recent release of a large number of genomes from ectomycorrhizal, orchid mycorrhizal and root endophytic fungi have provided deep insight into fungal lifestyle-associated genomic adaptation. Comparative analyses of symbiotic fungal taxa showed that similar outcomes of interactions in distant related root symbioses are examples of convergent evolution. The order Sebacinales represents a sister group to the Agaricomycetes (Basidiomycota) that is comprised of ectomycorrhizal, ericoid-, orchid- mycorrhizal, root endophytic fungi and saprotrophs (Oberwinkler et al., 2013). more...
