the taxonomic and phylogenetic status of several taxa previously recognized as subspecies inastragalus sect. anthylloidei is re-assessed based on dna sequences and morphologicalfeatures. we focused on astragalus ebenoides (subsp. ebenoides and subsp. naghadehensis),astragalus murinus (subsp. murins and subsp. bornmuelleri), astragalus remotiflorus (subsp.remotiflorus and subsp. melanogramma), a...

Plastid genomes exhibit different levels of variability in their sequences, depending on the respective kinds of genomic regions. Genes are usually more conserved while noncoding introns and spacers evolve at a faster pace. While a set of about thirty maximum variable noncoding genomic regions has been suggested to provide universally promising phylogenetic markers throughout angiosperms, appli...

Plastid genomes of higher plants contain a conserved set of ribosomal protein genes. Although plastid translational activity is essential for cell survival in tobacco (Nicotiana tabacum), individual plastid ribosomal proteins can be nonessential. Candidates for nonessential plastid ribosomal proteins are ribosomal proteins identified as nonessential in bacteria and those whose genes were lost f...

UNLABELLED PREMISE OF THE STUDY New primers were developed for Bignonieae to enable phylogenetic studies within this clade using herbarium samples. • METHODS AND RESULTS Internal primers were designed based on available sequences of the plastid ndhF gene and the rpl32-trnL intergenic spacer region, and the nuclear gene PepC. The resulting primers were used to amplify DNA extracted from her...

Most species of Paraphlomis are distributed in the south Yangtze River China. In this study, a new species, P. nana, from northeast Chongqing north is described and illustrated. Bayesian inference maximum likelihood analyses based on two nuclear ribosomal DNA regions (ITS ETS) three plastid markers (rpl32-trnL, rps16, trnL-trnF) were carried out to explore phylogenetic position within Paraphlom...

UNLABELLED • PREMISE OF THE STUDY The species-rich Neotropical genera Centropogon, Burmeistera, and Siphocampylus represent more than half of the ∼1200 species in the subfamily Lobelioideae (Campanulaceae). They exhibit remarkable morphological variation in floral morphology and habit. Limited taxon sampling and phylogenetic resolution, however, obscures our understanding of relationships bet...

Fission yeast cells express Rpl32-2 highly while Rpl32-1 lowly in log phase; in contrast, expression of Rpl32-1 raises and reaches a peak level while Rpl32-2 is downregulated to a low basic level when cells enter into stationary phase. Overexpression of Rpl32-1 inhibits cell growth while overexpression of Rpl32-2 does not. Deleting rpl32-2 impairs cell growth more severely than deleting rpl32-1...
