| morphological and molecular characterisation, and phylogenetic position of x. browni sp. n., x. penevi sp. n. and two known species of xiphinema americanum-group (nematoda, longidoridae). | using ribosomal (18s, its1, its2, d2-d3 expansion segments of 28s rdna) and mitochondrial (partial cox1 and nad4) dna markers in a study of several populations of xiphinema americanum-group from europe and morocco, two cryptic species xiphinema browni sp. n. (formerly reported as xiphinema pachtaicum) and xiphinema penevi sp. n. were revealed. the species are described, illustrated and their phylogenetic relationships discussed. the first species is most similar to xiphinema parasimile and is a ... | 2016 | 27110175 |
