Pericosines are unique C(7) cyclohexenoid metabolites of Periconia byssoides OUPS-N133 fungus that was originally isolated from the sea hare, Aplysia kurodai. Pericosines show significant in vitro cytotoxicity against P388 lymphocytic leukemia cells. Pericosine A, in particular, shows the most potent activity and significant in vivo antitumor activity against P388 cells. Thus, pericosines are p...

A range of fungi occur in the mangrove ecosystem although these differ as to their location and some fungi occur more frequently than others. In a study dealing with the frequency of occurrence of manglicolous fungi on Avicennia and Bruguiera from a mangrove habitat of Kerala, South India, 32 manglicolous marine fungi belonging to 23 ascomycetes, 1 basidiomycete and 8 mitosporic fungi were obta...

Fusicoccane diterpenoids usually possess a fused 5-8-5 tricyclic ring system, which are biogenetically generated from geranylgeranyl diphosphate (GGDP). In our report, three novel diterpenoid alkaloids with fusicoccane skeleton, pericolactines A-C (1-3), were isolated from Periconia sp.. Their structures with absolute configurations were determined by spectroscopic analyses and quantum chemical...

Results The data analyzed so far revealed the presence of different pollen and fungal species at both sites. The ratio between the pollen and fungal spores was 1:5. The airborne pollen grains showed quantitative and qualitative differences between the two sites. At FD site, the major pollen grains included Phoenix dactylifera (31%), grass pollen (14%), Atriplex nummularia (12%), Amaranthus viri...

Host-specific toxins from Helminthosporium victoriae (HV) and Periconia circinata (PC) caused gradual decreases in the negative electropotentials of single cells of susceptible but not of resistant plants. When tissues were held in a standard nutrient solution, the decrease (depolarization) induced by HV toxin was approximately 50 mv/hr; the decrease induced by PC toxin was even more gradual. C...
