Since then, the Nipponbare genome has served as the reference for the assembly of many additional genomes.
If, however, a pangene was identified as "rare" based on protein annotations but is found within many additional genomes when compared against whole DNA, it is not likely to be the result of HGT.
However, if the DNA sequence of the gene is present in many additional genomes from the same species, then this sequence was clearly not truly introduced into that species horizontally.
Many additional mt genomes from this group will need to be investigated to determine if there truly is a trend toward size increases in the non-coding regions of lice with type 3 minicircular mt genomes and what, if any, function these bloated non-coding regions serve in genome maintenance, replication, or transcription.
Many additional nematode genomes have been sequenced, and the continuing drop in cost will ensure that even more will be sequenced (Stein et al. 2003; Ghedin et al. 2007; Abad et al. 2008; Dieterich et al. 2008; Mortazavi et al. 2010; Jex et al. 2011; Kikuchi et al. 2011; Mitreva et al. 2011; Sommer and Streit 2011).
Recently, the genomes of the basidiomycete species Laccaria bicolor, Cryptococcus neoformans, Ustilago maydis, Coprinopsis cinerea (Coprinus cinereus) and Phanerochaete chrysosporium have been determined and many additional Basidiomycota genome projects are ongoing or about to be released ;, which could provide a rich database for additional Basidiomycota genomic survey evaluations.
This is a rather small fraction of the 20 000 genomes in the human genome (International Human Genome Sequencing Consortium, 2004), but recent large-scale re-sequencing projects of tumor genomes (Hudson et al., 2010) suggest many additional genes may be involved in tumorigenesis.
In addition, many additional peaks of H3K9me2 were detected across the genome, at levels comparable to constitutive heterochromatin domains.
Although the genomes of many additional nematode species are being sequenced [ 29, 30], even in this wider sampling of the phylum, Enoplea remains neglected.
Our analysis shows that as the number of sequenced prokaryotic genomes increases, many additional organisms lacking B12 biosynthesis will be identified.
In this study, we identified many additional SEO genes in the genomes of two Fabaceae and, interestingly, also in several non- Fabaceae plant families (which do not possess forisomes).
