چکیده
Abstract Root-knot nematodes ( Meloidogyne spp.) cause serious damages on most crops. Here, we report a high-quality genome sequence of exigua (population Mex1, Costa Rica), major pathogen coffee. Its mitogenome (20,974 bp) was first assembled and annotated. The nuclear then constructed consisting 206 contigs, with an N50 length 1.89 Mb total assembly 42.1 Mb.

DNA Complexity of the Root-knot Nematode (Meloidogyne spp.) Genome.
Cot curves derived from renaturation kinetics of sheared denatured DNA indicated that the genome of six populations representing the four most common root-knot nematode species (Meloidogyne incognita, M. arenaria, M. javanica, and M. hapla) is composed of 20% repetitive and 80% nonrepetitive sequences of DNA. Cot curves were almost identical, indicating that all populations had a haploid genome...
متن کاملMeloidogyne paranaensis n. sp. (Nemata: Meloidogynidae), a Root-Knot Nematode Parasitizing Coffee in Brazil.
A root-knot nematode parasitizing coffee in Paran State, Brazil, is described as Meloidogyne paranaensis n. sp. The suggested common name is Paraná coffee root-knot nematode. The perineal pattern is similar to that of M. incognita; the labial disc and medial lips of the female are fused and asymmetric and rectangular; the lateral lips are small, triangular, and fused laterally with the head reg...
متن کاملEffect of organic amendment on organic metabolites in root knot nematode (Meloidogyne Incognita) infested spinach
The Nematodes are roundworms that are found in every environment of the earth. While some species are harmful parasites, others play a vital role in nutrient cycle and medical research. Nematode infestation in the fields is poly-specific; however, depending on the agro-climatic conditions, one or two species are dominant over the rest. The present studies attempts to observe and control the roo...
متن کاملHost Range of the Root-Knot Nematode of Western Nebraska
Observations of the reaction of plants to the root-knot nematode of western Nebraska indicated a narrower host range than previously reported in other areas. Neal (8) *, Atkinson (1) and others (2, 10, 14) reported conflicting evidence on the reaction of plants to this pathogen. Tyler (14) recorded an extensive list of plants and their reaction to the nematode. Since then additional hosts have ...
متن کاملGenome-wide expression profiling of the host response to root-knot nematode infection in Arabidopsis.
During a compatible interaction, root-knot nematodes (Meloidogyne spp.) induce the redifferentiation of root cells into multinucleate nematode feeding cells (giant cells). Hyperplasia and hypertrophy of the surrounding cells leads to the formation of a root gall. We investigated the plant response to root-knot nematodes by carrying out a global analysis of gene expression during gall formation ...
