Predicting the secondary structure of RNA molecules from the knowledge of the primary structure (the sequence of bases) is still a challenging task. There are algorithms that provide good results e.g. based on the search for an energetic optimal configuration. However the output of such algorithms does not always give the real folding of the molecule and therefore a feature to judge the reliabi...

In a mycological research performed in the Sjeverni Velebit National Park, Croatia, a new species of Coprotus was discovered, described here as C. epithecioides. Along with the microscopic examination, phylogenetic analysis of the type material, based on ITS and LSU sequences, was performed in order to evaluate its relationship with the type species, C. sexdecimsporus. The type species was sequ...

This paper focuses on the mapping of alteration minerals and linear structures associated with gold mineralization in Giyani Greenstone Belt (GGB). Spectral Information Divergence (SID) Linear Unmixing (LSU) classification algorithms were applied to ASTER data using image extracted endmember spectra which match spectral profiles predominant (biotite calcite) related GGB. Directional convolution...

The phylogenetic position of the marine ascomycete genus Spathulospora was investigated using partial SSU and LSU DNA sequences obtained from dried herbarium specimens. Spathulospora was represented by the two species S. adelpha and S. antarctica. Phylogenetic analyses using Bayesian, parsimony, and neighbour-joining algorithms on SSU and LSU data sets agreed with the placement of Spathulospora...

Ribosomes transit between two conformational states, non-rotated and rotated, through the elongation cycle. Here, we present evidence that an internal loop in the essential yeast ribosomal protein rpL10 is a central controller of this process. Mutations in this loop promote opposing effects on the natural equilibrium between these two extreme conformational states. rRNA chemical modification an...

The basal fungal order Mortierellales constitutes one of the largest orders in the basal lineages. This group consists of one family and six genera. Most species are saprobic soil inhabiting fungi with the ability of diverse biotransformations or the accumulation of unsaturated fatty acids, making them attractive for biotechnological applications. Only few studies exist aiming at the revelation...

The positions of post-transcriptionally methylated residues within hamster mitochondrial ribosomal RNA have been established. Comparisons with other mitochondrial rRNA, and with bacterial, eucaryotic and chloroplast rRNA show that the methylated regions i) are comprised of conserved primary sequences and/or secondary structures and ii) are situated at the subunit interface of the ribosome. The ...

The interaction of a material with light is intimately related to its wavelength-scale structure. Simple connections between structure and optical response empower us with essential intuition to engineer complex optical functionalities. Here we develop local self-uniformity (LSU) as a measure of a random network's internal structural similarity, ranking networks on a continuous scale from cryst...

Clubroot disease caused by Plasmodiophora brassicae is one of the most important diseases of cultivated brassicas. P. brassicae occurs in pathotypes which differ in the aggressiveness towards their Brassica host plants. To date no DNA based method to distinguish these pathotypes has been described. In 2011 polymorphism within the 28S rDNA of P. brassicae was reported which potentially could all...
