Major emerging problems with minor meloidogyne species.
Root-knot nematodes (Meloidogyne spp.) represent one of the most polyphagous genera of plant-parasitic nematodes. To date, close to 100 valid species are recognized. In contrast to the size of the genus, the majority of past research focused on a small number of species, i.e., the so-called 'major' species M. arenaria, M. hapla, M. incognita, and M. javanica. This review highlights recent work ...
متن کاملMolecular diagnosis of meloidogyne species.
Genetic variation within nuclear and mitochondrial DNA of Meloidogyne species and host races has been evaluated for the development of root-knot nematode molecular diagnostics. This review summarizes the distinctive features of several useful DNA-based assays for plant-parasitic nematodes, focusing upon the direct application of these procedures for Meloidogyne detection, identification, and sy...
متن کاملA polymerase chain reaction method for identification of five major meloidogyne species.
A polymerase chain reaction (PCR) method for discriminating Meloidogyne incognita, M. arenaria, M. javanica, M. hapla, and M. chitwoodi was developed. Single juveniles were ruptured in a drop of water and added directly to a PCR reaction mixture in a microcentrifuge tube. Primer annealing sites were located in the 3' portion of the mitochondrial gene coding for cytochrome oxidase subunit II and...
متن کاملMinor Sounds of Major Importance
Prosody plays a big role in the human speech and is used for expressing emotions and attitudes in addition to the lexical words. This study looks at the possibility to use prosody in expressing attitudes with backchannels, such as /oh/, /m/, /uhu/ etc. In the study, two monosyllabic backchannels, /a/ and /m/, were chosen, created synthetically and manipulated systematically with regards to the ...
متن کاملInterrelationships of Meloidogyne Species with Flue-cured Tobacco.
Microplot and field experiments were conducted to determine relationships of population densities of Meloidogyne spp. to performance of flue-cured tobacco. A 3-yr microplot study of these interactions involved varying initial nematode numbers (P(i)).and use of ethoprop to re-establish ranges of nematode densities. Field experiments included various nematicides at different locations. Regression...
