Assessment of SCoT and DAMD molecular markers in genetic diversity and species delimitation of three moss species grown in Iran
This study was conducted to assess the efficacy of SCoT and DAMD molecular markers in genetic diversity of three moss species and compare them with ISSR marker. Another objective was to evaluate the suitability of these DNA markers in species identification (delimitation) in three moss species, including Neckera complanata, Homalothecium sericeum and Neckera cris...
متن کاملMitochondrial genome diversity in dagger and needle nematodes (Nematoda: Longidoridae)
Dagger and needle nematodes included in the family Longidoridae (viz. Longidorus, Paralongidorus, and Xiphinema) are highly polyphagous plant-parasitic nematodes in wild and cultivated plants and some of them are plant-virus vectors (nepovirus). The mitochondrial (mt) genomes of the dagger and needle nematodes, Xiphinema rivesi, Xiphinema pachtaicum, Longidorus vineacola and Paralongidorus lito...
متن کاملMorphological and Molecular Characterization of Longidorus americanum n. sp. (Nematoda: Longidoridae), a Needle Nematode Parasitizing Pine in Georgia.
We describe and illustrate a new needle nematode, Longidorus americanum n. sp., associated with patches of severely stunted and chlorotic loblolly pine, (Pinus taeda L.) seedlings in seedbeds at the Flint River Nursery (Byromville, GA). It is characterized by having females with a body length of 5.4-9.0 mm; lip region slightly swollen, anteriorly flattened, giving the anterior end a truncate ap...
متن کاملSpecies Delimitation and Description of Mesocriconema nebraskense n. sp. (Nematoda: Criconematidae), a Morphologically Cryptic, Parthenogenetic Species from North American Grasslands.
Nematode surveys of North American grasslands conducted from 2010 to 2015 frequently recovered a species of criconematid nematode morphologically resembling Mesocriconema curvatum. These specimens were recovered from remnant native prairies in the central tallgrass ecoregion of North America, and not from surrounding agroecosystems. Historical records indicate that M. curvatum is a cosmopolitan...
متن کاملSpecies delimitation and recognition in the Pediomelum megalanthum complex (Fabaceae) via multivariate morphometrics
Pediomelum is a genus endemic to North America comprising about 26 species, including the megalanthum complex, which consists of Pediomelummegalanthum and its varieties retrorsum and megalanthum, Pediomelummephiticum, and the recently described Pediomelumverdiense and Pediomelumpauperitense. Historically, species of the megalanthum complex have been variably recognized at the species or variety...
