Three problems in the taxonomy of Pancratium in Egypt are the lack of publications, a lack of clarity about the relationships between recently distinguished species, and the lack of markers for examining the levels and patterns of variation in rare and endemic species; the latter hinders work in plant conservation genetics. In this study we reassessed the taxonomic status of the Pancratium species of Egypt, and examined morphological and genetic variation within and between species, using specimens from different populations collected throughout its distribution range in the country. Our assessment was based on 38 macromorphological characters mainly representing vegetative parts, flowers, fruits and seeds, in addition to RAPD data. The results revealed five morphologically distinguished Pancratium species in Egypt, of which P. trianthum Herb. is newly recorded. Species identification was confirmed by two phenetic dendrograms generated with 26 quantitative morphological characters and RAPD data, while species delimitation was verified by principal component analysis. The diagnostic floral characters are those of the perianth, corona teeth, pistil, stamens, aerial scape, spathe, and number of flowers. The retrieved RAPD polymorphic bands show better resolution of the morphologically and ecologically closely allied Pancratium species (P. arabicum and P. maritimum), and also confirm the morphological and ecological divergence of P. tortuosum from the other studied species. These results are supported by the constructed UPGMA dendrogram.

Purification and properties of transcription factor IIIA (TF IIIA) from maize pollen (Zea mays L.) are presented for the first time. The purified protein has a molecular mass of about 35 kDa and exibits binding affinity toward both 5S rRNA and 5S rRNA gene. It also facilitates transcription of the 5S rRNA gene in a HeLa cell extract.

The lectin isolated from the leaves of Iris hybrida binds specifically N-acetyl-galactosamine and lactose. Its molecule consists of two identical subunits bound by disulfide bonds. The lectin is a glycoprotein containing about 12% of sugars. It binds asialoglycoproteins containing complex type sugar chains. The binding is reduced by half at the concentration of 0.15 to 0.40 mM of the galactose containing disaccharides irrespectively to a type of galactose isomer. This indicates rather broad specificity of I. hybrida leaf lectin.
