The three-dimensional structure of the ribosomal large subunit (LSU) reveals a single morphological element, although the 23S rRNA is contained in six secondary structure domains. Based upon maps of inter- and intra-domain interactions and proposed evolutionary pathways of development, we hypothesize that Domain III is a truly independent structural domain of the LSU. Domain III is primarily st...

The genus Euduboscquella is one of a few described genera within the syndinean dinoflagellates, an enigmatic lineage with abundant diversity in marine environmental clone libraries based on small subunit (SSU) rRNA. The region composed of the SSU through to the partial large subunit (LSU) rRNA was determined from 40 individual tintinnid ciliate loricae infected with Euduboscquella sampled from ...

ABSTRACT Ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) is present in all photosynthetic organisms and a key enzyme for photosynthesis-driven life on Earth. Its most prominent form hetero-oligomer which small subunits (SSU) stabilize the core of built from large (LSU), yielding, after chaperone-assisted multistep assembly process, an LSU8SSU8 hexadecameric holoenzyme. Here we use Chl...

Hans Rasmussen uses archival material from LSU Library's special collections to examine how and why nineteenth-century-Americans celebrated Louis Kossuth, an anti-Russian-imperialism activist, their behavior resembles pro-Volodymyr Zelensky sentiment today.

background: caddisflies have significant roles in freshwater ecosystems. morphological identification is the major impediment in accurate species identification of hydropsychids. mitochondrial and nuclear markers are suitable for molecular systematics of these group of arthropods. methods: trichopteran specimens of lavasan district in northeastern tehran, iran were collected in 2012, and de­scr...

Description of the subject. Soil organisms and their activities are essential for soil ecosystem functioning and they can thus be used as pertinent indicators of soil quality. Recent efforts have been undertaken to include biological indicators of soil quality into regional/national monitoring networks. Objectives. The aim of this study was to provide a first dataset of six biological indicator...

Distinguishing individual Russula species has been difficult due to extensive phenotypic plasticity and obscure morphological and anatomical discontinuities. Due to highly similar macroscopic features, such as the presence of a red-cap, species identification within the Russula subgenus Amoenula is particularly difficult. Three species of the subgenus Amoneula have been reported in Korea. We us...

Two monospecific genera of marine benthic dinoflagellates, Adenoides and Pseudadenoides, have unusual thecal tabulation patterns (lack of cingular plates in the former; and no precingular plates and a complete posterior intercalary plate series in the latter) and are thus difficult to place within a phylogenetic framework. Although both genera share morphological similarities, they have not for...

Most genes from the plant-specific family encoding Response to Low Sulphur (LSU)-like proteins are strongly induced in sulphur (S)-deficient conditions. The exact role of these proteins remains unclear; however, some data suggest their importance for plants' adjustment to nutrient deficiency and other environmental stresses. This work established that the regulation of ethylene signalling is a ...

Increasing college degree attainment for students from disadvantaged backgrounds is a prominent component of numerous state and federal legislation focused on higher education. In 1999, the National Science Foundation (NSF) instituted the ‘‘Computer Science, Engineering, and Mathematics Scholarships’’ (CSEMS) program; this initiative was designed to provide greater access and support to academi...
