Gene sequence analysis of toxins from the spider Phoneutria nigriventer revealed an intronless feature

Conclusions: Despite a few nucleotide substitutions in the genomic regions encoding for the toxin precursors when compared with cDNA sequences, the results of the present work indicate that P. nigriventer toxins do not contain introns in their genes sequences.
