Reviewer/Referee Access Agreement

You have reached this page using a special URL that is intended to be used by journal editors and reviewers or referees of a paper that is under consideration for publication. This URL gives you access to the submitted data and metadata associated with analyses and results presented in the paper under review. Please carefully examine the data paying special attention to the following:

• The citation data (authors, year, citation, abstract) should be complete, except for information that is not yet known (e.g. volume or page numbers).
• Verify that nexus files are error-free and executable by software programs (e.g. PAUP, Mesquite, MacClade, etc). Please make sure that the taxon labels for trees are identical, or a subset of, the taxon labels in data matrices connected by way of an analysis. If taxon labels in trees do not match with taxon labels in associated data matrices, the data will not be useful to the scientific community.
• Verify that data are not missing and that opportunities to supply valuable metadata are not overlooked. For example, TreeBASE can store Genbank accession numbers, museum voucher IDs, latitude and longitudes for specimen localities, character names and character state names for morphological data, etc. Including these metadata are sometimes overlooked by submitting authors, yet sharing this metadata is extremely valuable to the scientific community. Please use your power as a reviewer to encourage the sharing of richly-annotated metadata.
• Verify that analyses are not missing and that, where possible, analysis entries include software commands (e.g. the contents of a PAUP block or MrBayes block) so that analyses can be replicated easily (e.g. commands that describe substitution models, data partitions, and heuristic search parameters).
• Verify that taxon labels are mapped against TreeBASE's taxonomic dictionary. Data in TreeBASE can only be found using a taxon name search if the taxon labels are properly mapped.

By clicking the 'OK' button below, you agree to keep these data confidential; you agree not to retain these data after completing your report to the journal editor; you agree not to use these data or knowledge of these data for the purposes of your research until and unless the paper under review has been published and the data have been made available to the general public; you agree to keep the URL confidential.

Abstract

Austrocedrus chilensis [D.Don] Pic. Serm. et Bizarri (Pinales: Cupressaceae) is a keystone tree species in South America. Mortality of A. chilensis has been reported in most of its distribution in Argentina, and Phytophthora austrocedri has been identified as the causal agent. The aim of this work was to evaluate rhizospheric microorganisms present in A. chilensis roots as biocontrol agents against P. austrocedri. Growth of P. austrocedri was inhibited by seven fungal and four bacterial isolates in vitro. Interaction among isolates and P. austrocedri was microscopically studied and using dual culture techniques. Isolates with high in vitro effect were molecularly identified and inoculated in plants to evaluate their ability to reduce the effect of the pathogen. Two of the fungicide bacterial isolates were also able to induce a reduction of the syntomathology in A. chilensis trees. These findings are promising since they may contribute to the development of a biocontrol strategy to the disease
