Cercando EBRAEUS trovi un seminario per discutere delle differenti tossine di questo animale.
C'è solo un abstract...ma insomma in qualche modo sono velenose anche loro.
Conotoxin Diversity among Populations of Conus ebraeus
Conus ebraeus is one of the most widely distributed species of the genus Conus, with a range encompassing tropical regions of the Indian and Pacific Oceans.
Moreover, C. ebraeus shows slight differences in diet among populations. Analyses of conotoxin mRNA transcripts of C. ebraeus demonstrate that this species does not express orthologous counterparts of loci expressed by a close relative, C .
abbreviatus. These studies also reveal that allelic diversity of a conotoxin locus, locus E1, is quite high and that diversifying selection has operated among these alleles. Comparisons of expressed conotoxin transcripts among populations of C.
ebraeus from Okinawa, Guam, Samoa, Hawai’i and Panamá show that allele frequencies of conotoxin locus E1 differ among populations and that a second locus, E2, is differentially expressed among both populations and individuals. These findings suggest that differences in conotoxin allele frequencies among populations, strong diversifying selection operating among alleles of conotoxin loci and
differential expression of conotoxin loci among species, populations and individuals are three additional factors that contribute to differences in venom composition of Conus.
