A hitherto unidentified endophytic strain of the genus Chaetomium, isolated from the medicinal plant Otanthus maritimus, yielded a new tetrahydrofuran derivative, aureonitolic acid (1), along with 5 known natural products, 2-6. The structure of 1 was determined by extensive spectroscopic analysis and comparison with reported data. Extracts of the fungus, grown either in liquid culture or on sol...
Pseudococcus comstocki (Hemiptera: Pseudococcidae) is a mealybug species native to Eastern Asia and present as an invasive pest in northern Italy and southern France since the start of the century. It infests apple and pear trees, grapevines and some ornamental trees. Biocontrol programmes against this pest proved successful in central Asia and North America in the second half of the 20th centu...
Ecological restoration is crucial to counteract the degradation of coastal ecosystems. Recent studies increasingly suggest that success can be amplified by harnessing positive interactions between individuals foundation species, with clumped spatial designs as an easy-to-implement approach. However, are strongly context dependent, making it often difficult tell a priori if configurations would ...
چرای مستقیم دام و برداشت علوفه دو روش اصلی بهرهبرداری از چمنزارهای طبیعی و مصنوعی است. هدف این تحقیق بررسی اثرهای برش اندامهای هوایی روی ماده خشک کل، ماده خشک اندامهای هوایی، ماده خشک اندامهای زمینی، وضعیت پنجهزنی و احتمالاً تحمل چهار گونه مرتعی شوررویaeluropus lagopoides ، aeluropus littoralis، puccinellia distans و j. maritimus در مقابل برش است. این آزمایش در قالب فاکتوریل با طرح کامل تص...
The recently described ammonia-oxidizing archaea of the phylum Thaumarchaeota are highly abundant in marine, geothermal, and terrestrial environments. All characterized representatives of this phylum are aerobic chemolithoautotrophic ammonia oxidizers assimilating inorganic carbon via a recently described thaumarchaeal version of the 3-hydroxypropionate/4-hydroxybutyrate cycle. Although some ge...
Cell division is mediated by different mechanisms in different evolutionary lineages. While bacteria and euryarchaea utilize an FtsZ-based mechanism, most crenarchaea divide using the Cdv system, related to the eukaryotic ESCRT-III machinery. Intriguingly, thaumarchaeal genomes encode both FtsZ and Cdv protein homologues, raising the question of their division mode. Here, we provide evidence in...
Vineyards were surveyed for grapevine leafroll-associated viruses and their insect vectors in New York State's Finger Lakes region in 2006-2008. Grape mealybug, Pseudococcus maritimus (Erhorn) (Hemiptera: Pseudococcidae), European Fruit Lecanium, Parthenolecanium corni (Bouche), and Cottony Maple Scale, Pulvinaria acericola (Walsh and Riley) (Hemiptera: Coccidae) were identified as vector speci...
The growth characteristics of three Rumex species were determined under different solution oxygen concentrations in hydroculture. These species all occur in a river foreland ecosystem and they were found to differ in their flood tolerance. The flood-tolerant R. maritimus and R. crispus developed a large num ber of new, aerenchymatous roots within a short period under low solution oxygen concent...
