Morphological, Morphometric, and Molecular Characterization of Intraspecific Variations within Indian Populations of Meloidogyne graminicola

Fourteen populations of Meloidogyne graminicola were collected from different agroecological regions of India. Morphological and morphometrical comparisons were made for various nematode life stages. Three populations (Hisar, New Delhi, and Samastipur) were different from typical M. graminicola on the basis of the length of eggs; J2 length, a-value, hyaline tail portion; male length, distance up to excretory pore, spicule and gubernaculum lengths; female length and width, stylet length

Occurrence and molecular characterization of Meloidogyne graminicola on rice in Central Punjab, Pakistan

(Bridge et al., 2005; Win et al., 2015; Ali et al., 2015). Among various RKNs, Meloidogyne graminicola (Golden and Birchfield) has emerged as the most serious pest of rice (Mantelin et al., 2017). M. graminicola was first reported in Pakistan by Munir and Bridge (2003) during a survey of rice fields of Sheikhupura, Punjab, Pakistan. The subtropical climate of Pakistan and warm sandy soils are favorable for the development and reproduction of RKNs (Khattak, 2008). But plant-parasitic nematodes in these

Nematode Genome Announcement: A Draft Genome for Rice Root-Knot Nematode, Meloidogyne graminicola

The rice root-knot nematode Meloidogyne graminicola has emerged as a devastating pest of rice in South-East Asian countries. Here we present a draft genome sequence for M. graminicola, assembled using data from short and long insert libraries sequenced on Illumina GAIIx sequencing platform.

Silver nanoparticles as a potential nematicide against Meloidogyne graminicola

Rice (Oryza sativa) is a major life-sustaining crop in India and feeds more than 60% of the population. During 2014 to 2015, the area under rice crop in India was 43.86 million ha with a total rice production of 105.48 million tons (Anonymous, 2016). Rice root-knot nematode, Meloidogyne graminicola, is widely distributed across diverse agro-climatic conditions in India (Salalia et al., 2017) and it has emerged as the economically most threatening plant-parasitic nematode in rice nurseries

First report of rice root-knot nematode, Meloidogyne graminicola, infecting Juncus microcephalus in Brazil

striations were smooth and thick in the dorsal region of the vulva. Male measurements were L = 1,401.5 ± 150.5 (1,150.5-1,792.0) μm, stylet length = 19.5 ± 0.5 (17.9-20.2) μm, DGO = 3.5 ± 0.5 (2.4-4.0) μm, tail = 11.4 ± 1.5 (9.4-14.0) μm, spicule = 31.0 ± 1.4 (28.0-36.5) μm. The overall morphology and morphometrics of the population of fit into Meloidogyne graminicola (Golden and Birchfield, 1965) according to the original description (Golden and Birchfield, 1965).

Impact of a conservation agriculture system on soil characteristics, rice yield, and root-parasitic nematodes in a Cambodian lowland rice field

-parasitic nematodes (RPN) that substantially affect rice production in SE Asia (De Waele and Elsen, 2007). The rice root-knot nematode, Meloidogyne graminicola (Golden and Birchfield, 1965), is the principal Meloidogyne species found on rice in Asia causing rice yield losses ranging between 16 and 80% of the total crop production (Plowright and Bridge, 1990; Prot and Matias, 1995; Soriano et al., 2000; Padgham et al., 2004; Mantelin et al., 2017), depending on the rice agroecosystems and agricultural

Discovery and Identification of Meloidogyne Species Using COI DNA Barcoding

closely related species such as Meloidogyne konaensis were characterized by fixed diagnostic nucleotides. Species that were collected from multiple localities and strongly characterized as discrete lineages or species include Meloidogyne enterolobii, Meloidogyne partityla, Meloidogyne hapla, Meloidogyne graminicola, Meloidogyne naasi, Meloidogyne chitwoodi, and Meloidogyne fallax. Seven unnamed groups illustrate the limitations of DNA barcoding without the benefit of a well-populated reference library
