Annotation against the Arabidopsis thaliana proteome resulted in 36,371 contigs
(44.48% of the total) with a name and function assigned. On the other hand, preliminary differential expression (DE) analysis revealed more than 1000 contigs differentially expressed between temperatures, regardless of the moment of the day
(FDR-corrected p-value <0.05). This first step in the -omic study of N. pumilio will
be of great help to current and future studies related to functional genomics, local
genetic variation and adaptation and gene discovery and characterization in this
important native species.
In angiosperm native species, genome sequencing has also only been performed
on N. alpina and N. obliqua using Roche/454 technology (El Mujtar et al. 2014;
Table 17.1 see also SeqQual pipeline, available at https://github.com/garniergere/
SeqQual). Several local and online bioinformatics tools were combined for the
assembly, annotation and classification of produced genomic resources (Fig. 17.3).
Although it was a partial genome sequencing of low coverage (13.4 Mb of
