Nicotiana benthamiana is a member of the Solanaceae family and is widely used as an experimental model system in plant science, especially in the fields of plant pathology and for understanding interactions between organisms. However, N. benthamiana has a complex allopolyploid genome, the details of which have long been elusive. Kurotani et al. (on pp. 248-257) have now performed de novo whole-genome assembly in N. benthamiana using Hi-Fi technology with next-generation sequencing, resulting in improved genome assembly and annotation of N. benthamiana, which will undoubtedly render it more widely accessible for research.
The cover image shows an N. benthamiana plant at the flowering stage. The circular diagram indicates the comparison of genome structures between N. benthamiana and N. tabacum; inner blue ring, coverage of regions of high homology with N. sylvestris; middle red ring, coverage of N. tomentosiformis; outer blue half-ring and outer green half-ring, chromosomes of N. tabacum and scaffolds of N. benthamiana, respectively; blue and red lines in center, the linkage of SSR markers on N. sylvestris and N. tomentosiformis, respectively.
