Kültür Mantarı Pleurotus sajor-caju (Fr.) Singer Üzerine Bir Araştırma: Taksonomik Durumunun ve Doğru Adının Incelenmesi

Abstract

Geçmişten günümüze Pleurotus cinsine ait bazı mantarların taksonomisi ile ilgili bazı sorunlar bulunmaktadır. Pleurotus sajor-caju (Fr.) Singer ismi en yaygın kullanılan ticari kültür mantarı izolatı olarak karşımıza çıkmaktadır ve Pleurotus pulmonarius (Fr.) Quel. ile Lentinus sajor-caju (Fr.) Fr. türlerinin sinonimi olarak kullanılmaktadır. Günümüzde Index Fungorum ve MycoBank Database veri tabanlarında P. sajor-caju ismi güncellenmiş olup artık L. sajor-caju olarak kullanılmaktadır. Fakat, elimizdeki P. sajor-caju ticari örneği literatür ile karşılaştırıldığında morfolojik ve anatomik bakımdan L. sajor-caju (sap kısmında annulus bulunması, hifsel sistem dimitik yapıda ve bazidiyospor 5.5-8×1.8-2.5 µm) türünden farklılık gösterdiği ve adının L. sajor-caju olarak kullanılmasının yanlış olacağı düşünülmüştür. P. sajor-caju ismi ile sağlanan örneklerin gerçekte hangi türe ait olduğu karmaşık bir problem olarak görülebilmektedir. Yapılan bu çalışma ile P. sajor-caju olarak elde edilen ticari kültür mantarı örneğinin, mikro-makroskobik özellikleri (sap kısmında annulus olmaması, hifsel sistem monomitik özellikte, bazidiyospor 7.5-11×3-4.5 µm) ile moleküler düzeyde yapılan analizlerinde çalışılan türün gerçekte P. pulmonarius olduğu (% 99) kesinleşmiştir.

A Study on the Cultivated Mushroom Pleurotus sajor-caju (Fr.) Singer: Investigation of Its Taxonomical Status and the Correct Name

Abstract

There are some problems with the taxonomy of some fungi belonging to the Pleurotus genus from past to present. The name Pleurotus sajor-caju (Fr.) Singer appears as the most widely used commercial cultivated mushroom isolate and is used as a synonym of both Pleurotus pulmonarius (Fr.) Quel. and Lentinus sajor-caju (Fr.) Fr. species. Today, the name P. sajor-caju has been updated in the Index Fungorum and MycoBank Database databases and is now used as L. sajor-caju. However, when the commercial specimen of P. sajor-caju is compared with the literature, it is thought that it differs morphologically and anatomically from L. sajor-caju (the presence of annulus in the stipe, the hyphae system is dimitic and the basidiospore 5.5-8×1.8-2.5 µm) and it would be wrong to use its name as L. sajor-caju. Which species the samples provided with the name P. sajor-caju actually belong to can be seen as a complex problem. With this study, it was confirmed that the species studied was actually P. pulmonarius (99%) in the micro-macroscopic properties (absence of annulus in the stipe, hyphal system monomitic, basidiospore 7.5-11×3-4.5 µm) and molecular analysis of the commercial cultivated mushroom sample obtained as P. sajor-caju.
