Special Issue Information

Dear Colleagues,

Studies of plant–pathogen interactions have historically focused mainly on simple models of infection involving single host–single disease patterns. Plant infections usually involve multiple genera, species, and/or genotypes and exhibit complexities not captured in single host–single disease systems. Recent insights into co-infection systems focusing on host–pathogen interactions will be included in this Special Issue. Moreover, the implications for host susceptibility/resistance are of interest. During the last several decades, the study of plant–pathogen interaction has been enriched by the advent of new technologies and the application of multiple omics platforms. Omics technologies reflect the dynamic concept of biological processes and provide a contemporary approach to viral, bacterial, and fungal pathogens.

The aim of this Special Issue is to cover multiple aspects of pathogen interactions, with emphasis on the application of individual- and multi-omics-based technologies to uncover novel insights into the relationships between plants and their pathogens.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Populus laurifolia is one of the most valuable tree species in the world and an important silvicultural tree species in the Xinjiang Uygur Autonomous Region, China. In July 2017, an unreported brown leaf spot disease was observed on P. laurifolia in Altay City, Xinjiang. The causal agent of this leaf spot disease was isolated, and Koch’s postulates were performed to confirm its pathogenicity. Based on a morphological characterization and phylogenetic analyses, the causal organism was identified to be a fungal species, Coniolariella gamsii. The optimum mycelial growth conditions for C. gamsii are on PLPDA (Populus leaves potato dextrose agar) medium, at 28 °C, in the dark. The sporulation time when using PLPDA medium (12 days) is much less than that for PDA medium (25 days). Pathogenicity tests revealed that C. gamsii can also infect two other Populus species (P. bolleana and P. tomentosa). This is the first report of C. gamsii causing brown leaf spot disease on P. laurifolia, and the optimum culture and sporulation conditions have also been optimized for the first time. This study provides a theoretical basis for the diagnosis of this disease and the monitoring of the disease’s occurrence and epidemic status. Full article
