Phylogenetics of the genus Sechium P. Brown: A review

The Sechium P. Br. genus composed of 11 species, which originated from the mountainous regions Mesoamerica, have been domesticated and diversified. These species are clustered in two large groups: Mexican clade Central American clade. Morphological molecular studies shown that formed through interspecific hybridizations genetic flow, with exception S. mexicanum, is strongly linked to Sicyos. objective this review was analyze phylogenetics based on morphological studies, contributed taxonomic knowledge utilization, thereby favoring its conservation improvement. well supported data, but not so data. were geographically isolated endemic. edule tacaco exploited agricultural industrial sectors, both an extensive phenotypic diversity has allowed them diversify expand into different ecological niches.
