“…The fact that there is no known differential host plant found so far to distinguish between M. ethiopica and M. luci suggests that the two species are very closely related . Phylogenetic analyses further confirmed a very close relationship between M. ethiopica and M. luci species (Janssen et al, 2016;Geri c Stare et al, 2017). Therefore M. ethiopica (Carneiro et al, 2003(Carneiro et al, , 2007Aballay et al, 2009;Medina et al, 2014) as well as M. luci (Maleita et al, 2017) represent a serious threat to agriculture.…”

Record of a new location for tropical root knot nematode Meloidogyne luci in Slovenia

et al. 2017

View full text Add to dashboard Cite

The plant parasitic nematode Meloidogyne ethiopica Whitehead has been reported from several European countries including Slovenia, where it was first found in 2003. However, the description in 2014 of a new sister species, Meloidogyne luci Carneiro et al., , called for the reclassification of all European and Turkish populations of M. ethiopica reported up to this date as M. luci. Both M. ethiopica and M. luci have a very wide host range of monocotyledons and dicotyledons. They are pests of important agricultural crops such as maize, potatoes and variety of vegetables, and represent a serious threat for agricultural production in greenhouses as well as in the open fields in many EPPO countries. This paper reports a new location for the tropical root knot nematode species M. luci found in Slovenia in 2015.

Reaction of a heterozygous tomato hybrid bearing the Mi‐1.2 gene to 15 Meloidogyne species

et al. 2020

| INTRODUC TI ONRoot-knot nematodes (RKN) of the genus Meloidogyne are among the main sanitary problems of the tomato (Solanum lycopersicum) crop worldwide (Seid et al., 2015). So far, 18 Meloidogyne species have been detected in Brazil affecting a wide range of crops, including tomato and other vegetables, fruit trees, soybeans, coffee, cotton, and beans (Carneiro et al., 2016). Most of these RKN species can naturally infect tomato plants either across large geographic regions or in more restricted areas. However, the predominant Meloidogyne species infecting tomato worldwide are M. javanica, M. incognita, M. arenaria, M. hapla, and more recently M. enterolobii (= M. mayaguensis) (Brito et al., 2007; El-Sappah et al., 2019).Abstract Many root-knot nematode (RKN) species (Meloidogyne spp.) are polyphagous and cultivated tomato (Solanum lycopersicum) is one of their preferential hosts, leading to significant losses. It is known that the dominant Mi-1.2 gene in tomato confers resistance to the three most important RKN species-M. incognita, M. javanica, and M. arenaria, and minor species-M. ethiopica, M. hispanica, and M. luci. However, little information is available about resistance of tomatoes carrying this gene to other tomato-infecting RKN species. In this study, resistance conferred by the Mi-1.2 gene/ locus was evaluated against populations of 15 Meloidogyne species, employing tomato cultivars Santa Clara (homozygous recessive mi-1.2/mi-1.2, susceptible) and Debora Plus (heterozygous Mi-1.2/mi-1.2, resistant). Debora Plus was susceptible only to M. enterolobii and M. hapla, and was resistant to the other Brazilian populations of M. arenaria, M. ethiopica, M. exigua, M. hispanica, M. incognita, M. inornata, M. izalcoensis M. javanica, M. konaensis, M. luci, M. morocciensis, M. paranaensis, and M. petuniae. Mi-1.2 is located on tomato chromosome 6 within a cluster of seven homologous genes of the nucleotide-binding site leucine-rich repeat (NBS-LRR) family; further research is required to confirm if this multiple Meloidogyne spp. resistance phenotype is controlled exclusively by Mi-1.2 or by combined action of other closely linked genes. This evaluation of resistance of the Debora Plus cultivar to several Meloidogyne species suggests that the Mi-1.2 gene/locus may reduce losses induced by a wide range of Meloidogyne spp. Further studies using additional resistant cultivars and other populations of Meloidogyne spp. are needed to confirm these results.

“…The M. luci specific esterase enzyme phenotype (L3) is the best tool for differentiating this species from other Meloidogyne species (Carneiro et al, 2014;Gerič Stare et al, 2017;Maleita et al, 2018). Additionally, esterase studies can be supported with data from mtDNA regions.…”

Detection of the root-knot nematode Meloidogyne luci Carneiro et al., 2014 (Tylenchida: Meloidogynidae) in vegetable fields of Samsun Province, Turkey

The root-knot nematode, Meloidogyne luci Carneiro et al., 2014 (Tylenchida: Meloidogynidae), is commonly found in greenhouses in Samsun Province in northern Turkey but has not been reported in open fields. However, the most recent study on the distribution of root-knot nematodes in open fields of this region was conducted more than 20 years ago and identification was based on perineal patterns. Therefore, the aim of the present study was to update the distribution of Meloidogyne spp. in the vegetable fields of Samsun Province. For that purpose, soil samples were collected from 50 vegetable fields during July 2017. Nematode isolates obtained from bioassay tests were identified based on their esterase enzyme phenotype and identification was confirmed with molecular techniques. Root-knot nematodes were detected in 20% of the fields sampled. Meloidogyne luci was the most prevalent species, as was reported from greenhouses in Samsun Province, followed by Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 and Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949. Meloidogyne luci is reported for the first time from open fields in Turkey with this study.
