این تحقیق در سال های 1388 تا 1389 برای شناسایی عوامل تخریب و خشکیدگی جنگل بادام کوهی منطقه کوه سیاه دشتی و ارائه توصیه های کاربردی جهت مدیریت و کنترل این عوامل در استان بوشهر انجام شد. به منظور بررسی آفات، نمونه برداری های منظم دوره ای از درختان بادام کوهی انجام گردید. مراحل نابالغ حشرات، از طبیعت جمع آوری و در آزمایشگاه روی گیاه میزبان پرورش داده شد. بیماری شناسی گیاهی با انجام نمونه برداری، ج...
The following is a review of some of the work that we have done since 2007 regarding the importance of molds in the phenomenon of sick building syndrome (SBS). In these studies we first examined mold contamination in air handling units (AHU). Our results showed that Cladosporium sp. were commonly recovered in AHU as growth sites and free spores. They were found mainly on the blower wheel fan bl...
Jiao and Liu (Research Articles, 16 October 2015, aac4383) reported the crystal structure of the protein complex polycomb repressive complex 2 from Chaetomium thermophilum This landmark structure has brought invaluable insights into the activation mechanism of this essential methyltransferase. However, the analysis of the x-ray data discussed below suggests that the description of oncogenic H3K...
A screening study focusing on monoamine oxidase inhibitory activity on the EtOAc extract of an Ascomycete Chaetomium quadrangulatum, which previously gave five unique chromones possessing this activity (chaetoquadrins A-E (1-5)), this time afforded six new constituents termed chaetoquadrins F-K (6-11) in addition to 1-5. The structures of 6-11 have been deduced on the basis of spectral and chem...
The Cabo Rojo Solar Salterns located on the southwest coast of Puerto Rico are composed of two main ecosystems (i.e., salt ponds and microbial mats). Even though these locations are characterized by high solar radiation (mean light intensity of 39 mol photons m-2d-1) they harbour a diverse microscopic life. We used morphological and molecular techniques to identify a series of halotolerant fung...
Experiments have been made on the production of mutations by irradiation with monochromatic ultra violet light. The basic object of the experiments was to see whether thresholds exist in this phenomenon of the type familiar in photo-chemical reactions. If such thresholds can be demonstrated, a technique of analysis of biological material might be opened up similar to that used by the physicist ...
Jatropha curcas L., a perennial plant grown in tropics and subtropics is popularly known for its potential as biofuel. The plant is reported to survive under varying environmental conditions having tolerance to stress and an ability to manage pest and diseases. The plant was explored for its endophytic fungi for use in crop protection. Endophytic fungi were isolated from leaf of Jatropha curcas...
