Origin and rearrangement of ribosomal DNA repeats in natural allotetraploid Nicotiana tabacum are described. Comparative sequence analysis of the intergenic spacer (IGS) regions of Nicotiana tomentosiformis (the paternal diploid progenitor) and Nicotiana sylvestris (the maternal diploid progenitor) showed species-specific molecular features. These markers allowed us to trace the molecular evolu...
Tobacco (Nicotiana tabacum L. cv Samsun NN) leaves accumulate a cytoplasmic/nuclear lectin, called Nictaba, in response to methyl jasmonate. To check whether, and if so to what extent, the specific induction of this lectin applies to related species, a collection of 19 Nicotiana species--covering 12 Nicotiana sections and eight Nicotiana tabacum cultivars--was screened for their capability to s...
Nicotiana tabacum chloroplast DNA contains two copies each of 16S and 23S rRNA genes. These genes are located in an inverted order as determined from restriction fragment mapping and Southern hybridization to restriction fragments. The position of these genes on the N. tabacum chloroplast DNA molecule has been established relative to a complete map of SalI and SMaI restriction enzyme cleavage s...
Isolated, nick-translated Pvu II fragments of Nicotiana tabacum chloroplast DNA produce specific intra- and intergeneric hybridization signals with chloroplast DNA digests from several representatives of the Solanaceae. These data, along with similarities in restriction enzyme patterns, permit construction of physical maps for Nicotiana line 92 (a cytoplasmic substitution line), Atropa belladon...
BACKGROUND Many species of Nicotiana section Suaveolentes produce inviable F(1) hybrids after crossing with Nicotiana tabacum (genome constitution SSTT), a phenomenon that is often called hybrid lethality. Through crosses with monosomic lines of N. tabacum lacking a Q chromosome, we previously determined that hybrid lethality is caused by interaction between gene(s) on the Q chromosome belongin...
In flowering plants, RNA editing is a posttranscriptional process that converts specific C to U in organelle mRNAs. Nicotiana tabacum is an allotetraploid species derived from the progenitors of Nicotiana sylvestris and Nicotiana tomentosiformis. These Nicotiana species have been used as a model for understanding the mechanism and evolution of RNA editing in plastids. In Nicotiana species, the ...
Following the success of the 1 (st) Student Symposium by ISCB RSG-UK, a 2 (nd) Student Symposium took place on 7 (th) October 2015 at The Genome Analysis Centre, Norwich, UK. This short report summarizes the main highlights from the 2 (nd) Bioinformatics Student Symposium.
