amorpha-4, 11-diene synthase (ads) gene is the first and important gene in artemisinin biosynthesis pathway that why for many researchers, the study of how to regulate of this gene is important. transcription factors can change the expression rate of several genes simultaneously. in this study, six wild accessions of artemisia annua, collected from golestan province, were used. many known trans...

Sordariomycetes is an earlier-introduced and one of the widely distributed class Ascomycota. The was initially classified based on morphology in having inoperculate unitunicate asci. With development DNA phylogenetic analysis, several undetermined or polyphyletic members were reclassified. However, not all species belonging to this have been sequenced analyzed. There are a number species, espec...

Background and purpose: The objectives of our study were to identify invasive alien plant species (IAS) in the main Natura 2000 forest habitat types (FHT) along the Mura River in Slovenia, and to estimate their abundance and cover. The aim of our study was to find out a) Which IAS appear in the research forests? b) What is their frequency and cover percentage? c) Whether individual IAS prosper ...

rearrangement of the nucleolonema and pars amorpha of the nucleolus. In addition to being carcinogenic, 4-nitroquinoline-N-oxide and several of its derivatives have been shown to be potent mutagenic agents (18). Thus, 4-nitroquinoline-N-oxide has been reported to exert mutagenic effects in bacterial systems and in viruses (4). Yeast cells (18) after exposure to 4-nitro quinoline-N-oxide gave ri...

When deciding whether to translocate a species, it is important know likely benefits and risks. Thus, Novak et al.'s (2021) analysis of past species translocations assess their successes unintended consequences welcome. However, conclusion that “The widespread paucity negative impacts stemming from conservation are signal regulators, decision-makers, stakeholders conservationists can be entrust...

Salivary glands were fixed in cold 1 per cent osmium tetroxide in veronal-acetate buffer containing sucrose and embedded in methacrylate mixture or Araldite. The salivary gland nuclei of sclarids show a continuous production of nucleoli, which remain multiple and not consolidated into a single structure. The earliest recognizable nucleoli, which we call "elementary nucleoli," are aggregations o...
