The selection of suitable reference genes is crucial to accurately evaluate and normalize the relative expression level of target genes for gene function analysis. However, commonly used reference genes have variable expression levels in developing skeletal muscle. There are few reports that systematically evaluate the expression stability of reference genes across prenatal and postnatal develo...

The structure of the RNA binding target for Saccharomyces cerevisiae ribosomal protein L32 was examined using chemical and enzymatic probes as well as thermodynamic methods. In vivo, the production of yeast RPL32 is regulated by a feedback mechanism whereby RPL32 binds to the 5' end of its transcript and inhibits splicing. The binding site of ribosomal protein L32 on the L32 RNA transcript can ...

Imperata is a ubiquitous grass genus of the tribe Andropogoneae (Poaceae), distributed throughout world. Previous systematic studies had established that encompasses nine species although no phylogenetic molecular are available in which all taxa have been included. The American continent has largest number species, encouraging research into how these evolved. Here we present analysis based on t...

Biodiversitas 23: 3976-3983. spp.or locally known as spp.(Acehnese) already has strong basic evidence the treatment traditional tribes such cough medicine, fever and sprains, used to food spices. various place...

Plastid DNA sequences evolve slowly in palms but show that the family is monophyletic and highly divergent relative to other major monocot clades. It is therefore difficult to place the root within the palms because faster evolving, length-variable sequences cannot be aligned with outgroup monocots, and length-conserved regions have been thought to give too few characters to resolve basal nodes...

Phylogenetic reconstruction for Carex and relatives in tribe Cariceae is complicated by species richness and nearly cosmopolitan distribution. In this investigation, our main objective was to estimate evolutionary relationships in tribe Cariceae using DNA sequence data from two spacer regions in nuclear ribosomal genes (ITS and ETS-1f) combined with noncoding chloroplast DNA (trnL intron, trnL–...

Previous tribal classifications of Rhamnaceae have been based on fruit characters, resulting in the delimitation of large and otherwise heterogeneous groups. We evaluated the most recent classification with DNA sequences of two regions of the plastid genome, rbcL and trnL-F, from 42 genera of Rhamnaceae and representatives of the related families Elaeagnaceae, Barbeyaceae, Dirachmaceae, Urticac...

Given the ongoing decline of both pollinators and plants, it is crucial to implement effective methods to describe complex pollination networks across time and space in a comprehensive and high-throughput way. Here we tested if metabarcoding may circumvent the limits of conventional methodologies in detecting and quantifying plant-pollinator interactions. Metabarcoding experiments on pollen DNA...

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...
