Mitochondrial gene expression was characterized during meiosis in sunflower anthers. In situ hybridization experiments showed that there was a marked accumulation of four mitochondrial gene transcripts (atpA, atp9, cob, and rrn26) in young meiotic cells. This pattern of transcript accumulation was only detected for mitochondrial genes and not for transcripts of two nuclear genes (atpB and ANT) ...

A cladistic analysis of sequences from the chloroplast gene rbcL was used to determine the systematic affinities of Rhizophoraceae and Anisophylleaceae. This analysis rejects close relationships of Rhizophoraceae with Celastraceae or Elaeocarpaceae, suggested previously, and identifies Erythroxylaceae as sister group within the Malpighiales, supported by several morphological and anatomical cha...

We present a complete mitochondrial genomic sequence for the tanaidacean Arctotanais alascensis (Richardson, 1899); this is first mitogenome reported from order Tanaidacea. The 13,988 bp long and contains 13 protein coding two ribosomal RNA genes (as typical animal mitogenomes), 21 of 22 transfer RNAs; we did not detect an isoleucine (trnI) gene. gene differed markedly hypothetical ground patte...

Abstract Background Atractylodes DC is the basic original plant of widely used herbal medicines “Baizhu” and “Cangzhu” an endemic genus in East Asia. Species within have minor morphological differences, universal DNA barcodes cannot clearly distinguish systemic relationship or identify species genus. In order to solve these question, we sequenced chloroplast genomes all using high-throughput se...

Objective: Because infections caused by nontuberculous mycobacteria (NTM) are rapidly increasing globally, a need exists for developing novel antibiotics and discovering the mechanism of resistance. This research was aimed at understanding bedaquiline resistance in model NTM species Mycobacterium marinum ( M. ). Methods: The M strain subjected to mutant selection with different concentrations B...

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...

PREMISE OF THE STUDY Large genera provide remarkable opportunities to investigate patterns of morphological evolution and historical biogeography in plants. A molecular phylogeny of the species-rich and morphologically and ecologically diverse genus Mimosa was generated to evaluate its infrageneric classification, reconstruct the evolution of a set of morphological characters, and establish the...
