Chromosome-level genome assemblies of Nicotiana tabacum, Nicotiana sylvestris, and Nicotiana tomentosiformis

Scientific Data
The Solanaceae species Nicotiana tabacum, an economically important crop plant cultivated worldwide, is an allotetraploid species that appeared about 200,000 years ago as the result of the hybridization of diploid ancestors of Nicotiana sylvestris and ...

Evolution of repetitive DNA in angiosperms: examples from Nicotiana allopolyploids [PDF]

, 2012
PhDAllopolyploidy, interspecific hybridisation coupled with genome multiplication, is a prevailing force in the evolution of angiosperms. This thesis examines the consequences of allopolyploidy at the genomic level.

Blue Light Receptor PHR2-Mediated Spectrum Antiviral Immunity. [PDF]

Adv Sci (Weinh)
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Next generation sequencing analysis reveals a relationship between rDNA unit diversity and locus number in Nicotiana diploids [PDF]

, 2012
Background Tandemly arranged nuclear ribosomal DNA (rDNA), encoding 18S, 5.8S and 26S ribosomal RNA (rRNA), exhibit concerted evolution, a pattern thought to result from the homogenisation of rDNA arrays. However rDNA homogeneity at the single nucleotide

Comparative genome-wide characterization leading to simple sequence repeat marker development for Nicotiana

BMC Genomics, 2018
Background Simple sequence repeats (SSRs) are tandem repeats of DNA that have been used to develop robust genetic markers. These molecular markers are powerful tools for basic and applied studies such as molecular breeding.
