Nb, Future Plans
Our current plan is to improve the assembly of the Nicotiana benthamiana genome sequence and link the sequence to the nineteen chromosomes. We are also working to improve the gene annotation.
- Sequence an additional lane of a 5-kb mate-pair library at the Cornell-Weill facility.
- Use an F2 population (~96 individuals) developed by Dave Zaitlin (University of Kentucky) for a genotype-by-sequencing (GBS) approach using the Cornell Institute for Genomic Diversity facility.
- Sequence a 15-kb mate-pair library (University of Illinois-Urbana/Champagne Sequencing Facility).
- Create a new assembly of the genome sequence based on the data in the preceding text.
- Improve annotation using with RNA-seq data from various researchers.

Scientists at the Boyce Thompson Institute for Plant Research (BTI) released a draft sequence of the Nicotiana benthamiana genome which is accessible through the SGN BLAST tool and can be downloaded from an ftp site (see: http://solgenomics.net/). The project was funded by BTI and National Science Foundation grants IOS-1025642 and IOS-0343327. N. benthamiana is a widely used model for plant-microbe biology and other research applications. It is particularly useful because it is related to tomato and potato and is amenable to virus-induced gene silencing (VIGS) which facilitates the efficient functional study of plant genes. The draft sequence of N. benthamiana will allow better design of constructs for virus-induced gene-silencing (VIGS)...read more
