The Giant Sequoia played several crucial roles in the founding of the modern science of tree -ring dating. These included at least two central theoretical constructs and at least two minor ones; however, historical studies of dendrochronology are actively continuing and this list is expected to expand. Second only to the importance of the ponderosa pine (Pinus ponderosa) in the earliest days of...

BACKGROUND Hitherto available sources from literature mentioned several wild growing Allium species as "edible" or "medicinally used" but without any further specification. METHODS New data were gained during recent research missions: Allium plants were collected and shown to the local population which was asked for names and usage of these plants. RESULTS Information was collected about cu...

s SUMMARY Root disease fungi, particularly root rotting Basidiomycetes, are key drivers of forest ecosystems. These fungi have co-evolved with their hosts in various forest ecosystems and are in various states of equilibrium with them. Management activities and various land uses have taken place in recent times that have dramatically altered edaphic and environmental conditions under which fore...

A new species of Scyphophyllidium inhabits Mustelus mento near La Paloma, Uruguay. It resembles Scyphophyllidium giganteum from the Atlantic Ocean and specimens identified as S. giganteum from California by having anapolytic strobilae 155-258 mm long, 250-300 craspedote proglottids, scoleces 1.2-1.4 mm wide, necks 34-41 mm long, immature and mature proglottids wider than long, gravid proglottid...

Due to the ease with which chromosomes can be observed, the Allium species, and onion in particular, have been familiar materials employed in cytogenetic experiments in biology. In this study, centromeric histone H3 (CENH3)-coding cDNAs were identified in four Allium species (onion, welsh onion, garlic and garlic chives) and cloned. Anti-CENH3 antibody was then raised against a deduced amino ac...

Plants of the Allium genus produce sulphur compounds that give them a characteristic (alliaceous) flavour and mediate for their medicinal use. In this study, the chemical composition and antimicrobial properties of Allium cepa red cv. and A. sativum in the context of three different drying processes were assessed using metabolomics. Bulbs were dried using either microwave, air drying, or freeze...

the effects of allium sativum on yogurt formation and subsequent storage (4°c, up to 28 days) on proteolysis, microbial activity, and inhibition of α-amylase, α-glucosidase and angiotensin-i converting enzymes were investigated in vitro. allium sativum yogurt showed higher rates of ph reduction and increment of titrable acid than control during the incubation at 41°c. highest proteolysis was ob...
