Special Issue Information
Dear Colleagues,
Chitin is a homolpolymer of N-acetylglucosamine units joined by b1,4-linkages. It is the second most abundant biopolymer in nature after cellulose. Chitin, an insoluble polymer, represents the structural component of exoskeleton of insects and crustacean and the fungal cell wall. Chitin synthase, a usually zymogenic enzyme, is involved in its synthesis while degradation of chitin oligomers depends on chitinase which, in addition of this function, it is important in a number of biological and biotechnological processes such as agriculture and pharmaceutical industry. Early in 1970-1980, the cell location and the mechanism of synthesis of fungal chitin was a matter of a strong debate. On one side, some scholars proposed the cell membrane as the required and timely synthesis of chitin while others discovered some microvesicles known as chitosomes that carry all components to the fungal tip to form chitin. Chitin microfibrils were formed by chitosomes in vitro for the first time regardless of the presence of the cell or its membranes. As research advanced, several forms or isoforms of chitin synthase and genes were unveiled in different fungi showing somewhat distinct properties and functions. The purpose of this SI is to update the state of the art of fungal chitin synthesis and degradation.

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. Journal of Fungi 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 2600 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.
