Special Issue Information

Dear Colleagues,

Plant pathogens such as bacteria, fungi, nematodes and viruses infect agricultural crops worldwide and pose a continuous threat to food security and agriculture. Plant pathogens cause yield losses of more than USD 220 billion. Therefore, timely identification and diagnosis are key for the effective management of plant pathogens in order to minimize their effects on crop productions and ultimately the quality and quantity of crop yields. The accurate identification of pathogens is based on the development of rapid, efficient and reliable diagnostic techniques for specific plant pathogens. Therefore, the need arises to focus on the range of currently available techniques that are used worldwide for the detection of plant pathogens. 

In this Special Issue of Pathogens, authors are welcome to submit papers on the traditional and advanced identification techniques specific to bacteria, fungi, nematodes and viruses. It is our intention that this Issue focus on biological characterization (host range, symptomatology, transmission), serological techniques and molecular or nucleic acid-based characterization (RT-PCR, genome characterization, cloning, Sanger sequencing, high-throughput sequencing, and nanopore sequencing), which are helpful in the development long-term integrated management strategies.

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. Pathogens 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 2200 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.

Ginger is an important spice crop in the north-eastern region of India. Rhizome rot, also called soft rot, is one of the most devastating diseases found in ginger that causes yield losses of up to 100% under favourable conditions. Initially, the disease symptoms appear as a light yellowing of the leaf tips that gradually spreads down to the leaf blade of lower leaves and the leaf sheath along the margin. Under favourable environmental conditions, the disease spreads rapidly, potentially causing significant crop damage. The pathogen can infect at any stage of crop growth, and under favourable environmental conditions, the disease spreads rapidly, failing the crop. Current research emphasises mitigating the losses caused by the devastating disease by using management strategies and biocontrol agents (BCAs). Results revealed that the average highest percent rhizome germination, lowest mean disease incidence, lowest mean disease severity index, lowest coefficient of disease index value, highest rhizome yield and benefit–cost ratio were recorded with Trichoderma harzianum (10 g/kg of rhizomes) + soil application of T. harzianum-enriched well-decomposed farm yard manure (3 kg of T. harzianum mixed with 100 kg FYM at 10–15 days before sowing) + soil drenching with T. harzianum at the rate 10 kg/ha, compared to the untreated control. Furthermore, soil chemical properties such as pH, electrical conductivity, soil organic carbon, total available nitrogen, total available phosphorus, and total available potassium play critical roles in rhizome rot disease severity. BCAs can suppress the phytopathogenic fungi and modulate different functions in plants. Full article

Yellow rose (Rosa xanthina) is a common ornamental shrub species widely cultivated in China. However, canker disease symptoms were discovered during our investigations in Beijing and Xinjiang, China. The fungal isolates were obtained from diseased barks and identified using combined methods of morphology and phylogeny based on a partial region of ITS, LSU, rpb2, tef1, and tub2 sequences. As a result, a new species of Seimatosporium named S. chinense was proposed and described herein. The new species is distinguished from its phylogenetic sister species, S. gracile and S. nonappendiculatum, by conidial characters. The present study improves the species concept in Seimatosporium and provides fundamental data for the yellow rose canker disease control in the future. Full article
