Journal ArticleDOI
Phylogenetic relationships of Phytophthora andina, a new species from the highlands of Ecuador that is closely related to the Irish potato famine pathogen Phytophthora infestans
TL;DR: Phylogenetic relationships of Phytophthora infestans sensu lato in the Andean highlands of South America were examined and sequences of the cytochrome oxidase I (cox I) gene and intron 1 of ras gene suggested that P. andina might have arisen via hybridization between P.infestans and P. mirabilis.
Journal ArticleDOI
Meloidogyne lopezi n. sp. (Nematoda: Meloidogynidae), a new root-knot nematode associated with coffee (Coffea arabica L.) in Costa Rica, its diagnosis and phylogenetic relationship with other coffee-parasitising meloidogyne species.
Danny A. Humphreys-Pereira,Lorena Flores-Chaves,Melissa Gómez,Luis Guillermo Loría Salazar,Luis Gómez-Alpízar,Axel A. Elling +5 more
TL;DR: Isozyme analyses and PCR-RFLP of the COII-16S rRNA mitochondrial gene region enable a clear diagnostic differentiation between these species, and characterisation of the protein-coding map-1 gene and phylogenetic analyses suggested that M. lopezi n.
Journal ArticleDOI
Presence of Meloidogyne enterolobii Yang & Eisenback (=M. mayaguensis) in guava and acerola from Costa Rica
Danny Antonio Humphreys,Valerie M. Williamson,Luis Guillermo Loría Salazar,Lorena Flores-Chaves,Luis Gómez-Alpízar +4 more
TL;DR: Size of PCR products of both mitochondrial regions and the sequence of the 63 bp repeat region supported the identity of these isolates as M. enterolobii (=M. mayaguensis).
Journal ArticleDOI
Molecular and morphological characterisation of Scutellonema bradys from yam in Costa Rica and development of specific primers for its detection
Danny A. Humphreys-Pereira,Valerie M. Williamson,Sooung Lee,Daniel Coyne,Luis Guillermo Loría Salazar,Luis Gómez-Alpízar +5 more
TL;DR: Analysis of DNA sequences from the ITS region indicated that populations from Costa Rica were monophyletic with S. bradys from West Africa and clearly distinct from other Scutellonema species.
Journal ArticleDOI
IDENTIFICACIÓN MEDIANTE PCR DEL SEXO DE LA PAPAYA (Carica papaya L.), HÍBRIDO "POCOCÍ"
Ericka Saalau-Rojas,Walter Barrantes-Santamaría,Carlos Loría-Quirós,Arturo Brenes-Angulo,Luis Gómez-Alpízar +4 more
TL;DR: Las plantas hermafroditas fueron llevadas al campo y al momento of the floracion se determino su sexo, y la correspondencia entre el sexado por PCR y the expresion sexual en campo fue de un 98 %.
