TaxID: 59747
Basic Information
Meloidogyne chitwoodi
Columbia Root-knot Nematode, Maiswortelknobbelaaltje
Meloidogyne chitwoodi is a plant pathogenic root-knot nematode that is a crop pest of potatoes, carrots, and black salsify. Root-knot nematodes such as M. chitwoodi cause the production of root-knot galls when their larvae infect the plant's roots and capture nutrients stored in the roots.

Morphological Features
Body pearly white, globular to pear-shaped, with slight posterior protuberance occasionally and a distinct neck situated anteriorly on a median plane with terminal vulva. Perineal pattern distinctive: striae around and above the anal area are broken, curved, twisted, or curled; pattern round to oval, sometimes with inner striae forming an arch. Vulva sunken in an area devoid of striae. Small vesicles present in median bulb, clustered around lumen anterior to valve plates. Stylet small but strong with dorsal curvature and rounded knobs sloping posteriorly. Males slender, vermiform, tapering at both ends (length 887–1268 µm), with large labial disc and a postlabial annule not divided into annules; spicules arcuate with dentate tips. Second-stage juveniles (J2) length 336–417 µm, tail short and blunt with a hyaline terminal having little or no taper to its rounded terminus; lateral field with four lines.

PRJNA1190951 SRX26985164 SRP549628 general RNAseq of resistant potato 8 days post M. chitwoodi race 1 infection replicate3 galled potato root tissues at 8 dpi were collected. Total nematode RNA was extracted using PureLink RNA Mini Kit (ThermoFisher). High quality total RNA (1-2 g, 260/280 = 1.8-2.2, with RIN value of RNA of at least 8.5) was packed on dry ice and sent to Novogene Co. Ltd for library preparation and sequencing (30M reads per sample with PE150) using the Illumina platform.
