Based on sequence data from ITS rDNA, cox1 and cox2, six Peronospora species are recognised as phylogenetically distinct on various Papaver species. The host ranges of the four already described species P. arborescens, P. argemones, P. cristata and P. meconopsidis are clarified. Based on sequence data and morphology, two new species, P. apula and P. somniferi, are described from Papaver apulum ...

BACKGROUND AND AIMS Representatives from Papaver, Roemeria, Stylomecon and Meconopsis were studied to elucidate phylogenetic relationships between Papaver and these closely allied genera. METHODS Two molecular data sets were used individually and combined and included sequences from the internally transcribed spacer region (ITS) of 18S-26S nuclear ribosomal DNA and the trnL intron and the trn...

The Romanian hamster Mesocricetus newtoni is endemic to South-Eastern Romania (Dobruja region) and North-Eastern Bulgaria, prefers steppic, arid, uncultivated habitats, but also found in alfalfa fields, less often corn cultures field-protecting vegetation belts. Previous studies provide only limited data regarding the diet of this cryptic species. one family group (one female four pups) was mon...

Many angiosperms use specific interactions between pollen and pistil proteins as "self" recognition and/or rejection mechanisms to prevent self-fertilization. Self-incompatibility (SI) is encoded by a multiallelic S locus, comprising pollen and pistil S-determinants. In Papaver rhoeas, cognate pistil and pollen S-determinants, PrpS, a pollen-expressed transmembrane protein, and PrsS, a pistil-e...

[1] New maps of kilometer-scale topographic roughness and concavity of the Moon reveal a very distinctive roughness signature of the proximal ejecta deposits of the Orientale basin (the Hevelius Formation). No other lunar impact basin, even the just-preceding Imbrium basin, is characterized by this type of signature although most have similar types of ejecta units and secondary crater structure...

[1] Moon Mineralogy Mapper (M) image and spectral reflectance data are combined to analyze mare basalt units in and adjacent to the Orientale multiring impact basin. Models are assessed for the relationships between basin formation and mare basalt emplacement. Mare basalt emplacement on the western nearside limb began prior to the Orientale event as evidenced by the presence of cryptomaria. The...

Introduction: Many impact basins on the Moon are filled with extensive mare basalts [1]. This obscures a) the primary structure of fresh basin interiors, including the nature and distribution of impact melts, and b) the nature of the early stages of the filling of basins with mare basalts. In contrast, the interior of the Orientale basin, the youngest and most well-preserved large basin on the ...

In an effort to characterize individual eruptive phases and events, 86 isolated mare deposits (ponds) in the lunar South Pole-Aitken and Orientale regions were analyzed to obtain information on areas, volumes, and other characteristics. Deposits likely to represent single eruptive episodes have area mean values of-2000 km 2 in the South Pole-Aitken Basin and -1100 km 2 in the Orientale Basin. P...
