The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

ABSTRAKT

We studied the role of lectin-carbohydrate recognition as a biospecific interaction during co-cultivation of the culinary-medicinal Basidiomycetes species Grifola frondosa and the diazotrophic bacterium Azospirillum brasilense Sp245 on an agar-supplemented medium. We showed that A. brasilense Sp245 and its Omegon-Km mutants, KM018 and KM139, defective in lipopolysaccharide (LPS) structure, whose LPSs contain O-specific polysaccharide (acidic OPS1, linear D-rhamnan), a hapten for the fungal lectin, are recognized by the fungus with the least antagonism, as distinct from mutants KM252 and KM348, which have neutral OPS2 and are inhibitory to the growth of the G. frondosa 0917 mycelium. Studying the influence of a pure lectin preparation on the motilities of these strains in a liquid medium, with the exception of the immotile KM018, revealed a decrease in the swimming speeds of Sp245 and KM139. The motilities of KM252 and KM348 were almost unaffected by the lectin. The obtained results attest to the involvement of biospecific lectin-carbohydrate interactions in the primary contact between the G. frondosa 0917 mycelium and the bacterium A. brasilense during co-cultivation. It is most probable that, in this case, the lectin acts as an attractant-like factor on the bacteria, thus ensuring the recognizing and protective functions of the fungus.
