In this study three polyploid Arum Linnaeus, 1753 species from Southern Italy were chromosomally investigated. Arum italicum Miller, 1768 was found to have 2n = 84 chromosomes and a karyotype composed of numerous asymmetric chromosomes. Arum maculatum Linnaeus, 1753 and Arum apulum (Carano) P. C. Boyce, 1993 were found to have 2n = 56 chromosomes. In the examined taxa some chromosome pairs were...

Arum palaestinum has a wide use in traditional medicine. It used in folk medicine as a remedy for treatment of post-delivery pain, inflammation, and internal infections. The analgesic activity of the methanolic extract of Arum palaestinum was evaluated using various experimental models in mice and rats. Antinociceptive effect of methanolic extract of Arum palaestinum was carried out both periph...

Learning gain in higher education (HE) has risen to international prominence through US sociologists Richard Arum and Josipa Roksa’s Academically Adrift, published in 2011. It has become a benchmark study and key reference point for current research and policy thinking in the field. This briefing summarises Arum and Roksa’s findings based on their research in the USA. It details their conclusio...

TrnL-F region including intron trnL (UAA) and trnL (UAA) - trn (GAA) spacer in the large single-copy region of the chloroplast genome is widely used to infer phylogenetic relationships in plants. In this study, we obtained the trnL-F sequences from 8 samples of Arum L. in Iran. Phylogenetic analyses were conducted by the Bayesian inference, maximum parsimony, and maximum likelihood methods. The...

ABSTRACT: This study examines the antibacterial effects of Arum conophalloides on S. typhimurium bacteria at different temperatures (–18°, 8°, 16°, 24°, and 32°C) and time intervals (1, 2, 3, 6, 12, 24, and 48 days). This local plant was studied to determine the greatest effect caused by the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) as well as the a...

The Solomon's lily arum mimics the odours of yeast to attract drosophilid flies as unrewarded pollinators.

The internal transcribed spacer regions of nuclear ribosomal DNA are widely used to infer phylogenetic relationships in plants. In this study, it was obtained the ITS sequences from 24 samples of Araceae in Iran, representing 3 genera: Arum L., Biarum Schott. and Eminium (Blume) Schott. Phylogenetic analyses were conducted by Bayesian inference and maximum Parsimony methods. Cladistic analysis ...

The activity of pyrophosphate:fructose-6-phosphate 1-phosphotransferase [PFK (PPi); EC 2.7.1.90] in extracts of the storage tissues of leek (Allium porrum), beetroot (Beta vulgaris) and roots of darnel (Lolium temulentum) exceeded 0.15 mumol/min per g fresh wt. As net flux from fructose 1,6-bisphosphate to fructose 6-phosphate in these tissues is unlikely, it is suggested that PFK (PPi) does no...
