summary: GigaScience's T2T Series has now launched, with our first papers showcasing
new Telomere-to-Telomere methods and genomic data sets. While the first draft
of the Human Genome was declared complete in April 2003, it took a further two decades
for the publication of the first complete, gapless sequence of a human genome in
March 2022.

*GigaScience\'s T2T Series has now
[launched](https://academic.oup.com/gigascience/pages/t2t-series-closing-the-gaps-from-telomere-to-telomere),
with our first papers showcasing new Telomere-to-Telomere methods and
genomic data sets.*
While the first draft of the Human Genome was declared complete in April
2003, it took a further two decades for the
[publication](http://doi.org/10.1126/science.abj6987) of the first
complete, gapless sequence of a human genome in March 2022. The work was
done by the [Telomere to Telomere (T2T)
consortium](https://sites.google.com/ucsc.edu/t2tworkinggroup?pli=1),
which was a years-long global collaboration led by geneticists at UC
Santa Cruz, University of Washington, and the National Institutes of
Health. This T2T approach has now moved onto to other species\' genomes
(for example see the [recently published first
outputs](https://doi.org/10.1038/s41586-024-07473-2) from the
[T2T-Primates](https://github.com/marbl/Primates) project of the
consortium), and what was originally just the name of the consortium has
now become a badge for a certain level of quality that enables new
understanding of biology and improvements in genome annotation.
With the interest in this new level of genome sequence, the new data and
tools coming from this research, and the new biological insight coming
from previously ignored corners of the genome, *GigaScience* is [pleased
to announce](https://gigasciencejournal.com/blog/t2t-series/) the launch
of new [thematic
series](https://academic.oup.com/gigascience/pages/collections) covering
T2T Genomics. [This T2T
series](https://academic.oup.com/gigascience/pages/t2t-series-closing-the-gaps-from-telomere-to-telomere)
providing a home for these discussions, updated datasets, and showcasing
of the new technologies and methods that have driven this new standard
in genomics.
The first batch of papers are [now
out](https://academic.oup.com/gigascience/pages/t2t-series-closing-the-gaps-from-telomere-to-telomere)
and demonstrate the scope of the series, and rapid development of this
field. With an interesting balance of new methods and papers presenting
new data. From new tools for [mapping and visualization of the
low-complexity regions](https://doi.org/10.1093/gigascience/giad101)
that previously were too challenging to assemble, to new computational
approaches to sort and assemble equally challenging [sex-limited
chromosomes](https://doi.org/10.1093/gigascience/giae015). And following
our first fully-resolved genome of the protozoal agent [*Cryptosporidium
parvum*](https://doi.org/10.1093/gigascience/giac010), we\'ve now
published much longer and difficult to assemble plant genomes such as
the [cupuassu tree (*Theobroma
grandiflorum*)](https://doi.org/10.1093/gigascience/giae027) and the
Chinese medicine plant [Qianhu (*Peucedanum praeruptorum*
Dunn)](https://doi.org/10.1093/gigascience/giae025). Providing novel
molecular insights into the many bioactive and commercially important
genes . With many more plant and animal species genomes currently under
review, watch this space for the final chapter of these reference
genomes to be published.
We would like to thank our Guest Editors Jue Ruan (Chinese Academy of
Agricultural Sciences) and Fritz J Sedlazeck (Baylor College of
Medicine), who both have hands-on involvement in this rapidly moving
field, and have helped draw up guidelines of what can be considered for
the series.
Please [contact
us](https://gigasciencejournal.com/blog/t2t-series/editorial@gigasciencejournal.com)
if you have work of interest you would like to discuss, or you can
submit through our submission system and make a note of this series in
the covering letter.
