Mining sequences with similarity to genes in the L. transcriptome: introductory step for identifying homologous genes.

The () genes in (L.) Heynh. form part of a group of mechano-stimulated genes and play an important role in abiotic stress tolerance. Mining the RNAseq transcriptomic database of 40,430 potato ( L.) genes based on functional annotation and homology search, our objective was to discover potentially homologous genes. A Gene Ontology-based homology search and functional annotation discovered, from among the 33 () and 25 tomato ( L.) () genes, 35 gene sequences corresponding to 20 genes and 40 gene sequences corresponding to 21 genes, respectively. Thirteen sequences corresponding to 11 putative genes in potato, named as after SlXTH genes, were significantly up- or down-regulated in response to ultrasound. These putative genes in potato can serve for future functional genetic analyses.
