Marasmius palmivorus is a marasmioid fungal species that exhibits parasitic behaviour, although most marasmioids are rarely parasitic. The fungus has been reported to cause fruit bunch rot disease of oil palm and coconut, but only a few studies on its pathogenic behaviour are available, particularly on oil palm. Hence, there is a need to assess the ability of the fungus to act as a pathogen and to study its molecular evolution and taxonomy. Nine isolates of M. palmivorus were successfully isolated from basidiocarps and diseased fruitlets of oil palm collected from oil palm plantations and were morphologically characterized on potato dextrose agar (PDA) followed by molecular identification based on nucleotide sequence alignments of internal transcribed spacer (ITS) regions of ribosomal RNA (rRNA) gene clusters with sequences from GenBank. Koch's Postulates confirmed that M. palmivorus could infect oil palm fruitlets with symptoms similar to those observed for bunch rot disease. Molecular phylogenetic studies using nucleotide sequences of ITS and the nuclear ribosomal large subunit (nLSU) showed that isolates sharing the same phenotypic characteristics of Marasmius palmivorus and Marasmiellus palmivorus are monophyletic and share a common ancestor. The fungus has also been shown to be more closely related to the genus Marasmius than Marasmiellus; therefore, we support retention of the taxon name of the pathogen causing bunch rot disease of oil palm as Marasmius palmivorus.  相似文献

Mushroom stalk waste (MSW) generated from the oyster mushroom industry is drastically increasing and safe disposal of MSW is becoming a critical issue worldwide. Mushrooms are an established, excellent source of nutraceuticals and antioxidants, and therefore MSW may confer similar effects when consumed. The severe deterioration of aquatic habitat may compromise the homoeostasis of antioxidative metabolism of Nile tilapia, Oreochromis niloticus, which resulted in a reduced total production. Based on this paradigm, hot water extracts (HWE, 2‐ and 5‐h) of MSW were evaluated as a supplement in fish feed and determined the effect on growth performance and the antioxidant status of Nile tilapia, O. niloticus, in vivo. The HWE 5‐h contained significantly higher amounts of nutrient and β‐glucan than HWE 2‐h (P < 0.05). Four standardized in vitro antioxidant assays showed that HWE 5‐h was a better antioxidant agent than HWE 2‐h (P < 0.05). Tilapia fingerlings fed 5 g kg^?1 HWE supplemented feed produced better (P < 0.05) growth and higher antioxidant enzyme activities than 10 g kg^?1 HWE, CD and BD. Thus, HWE of MSW included at 5 g kg^?1 may be beneficial to tilapia farming and may also provide a way of disposing the waste created by mushroom farming.  相似文献
