“…This nematode has been reported as a serious pest to various cultivated plants (Chitambar, 1993;Emilse et al, 2011;Subbotin et al, 2014;Nguyen and Trinh, 2021). However, its damage to the Citrus trees was not assessed during the present study.…”

“…Helicotylenchus dihystera and Tylenchorhynchus zeae can be potential pests to vegetables, maize and soybean (Firoza and Maqbool, 1995;Brücher et al, 2019;Machado et al, 2019, Xu et al, 2020. Hemicycliophora poranga can seriously infect vegetables and sugar-beet (Chitambar, 1993;Emilse et al, 2011;Nguyen and Trinh, 2021) and Nanidorus minor is a potential threat to several plants due to the risk of tobravirus transmission. Scutellonema brachyurus is mainly prevalent in tropical and subtropical areas (van den Berg et al, 2013;Machado et al, 2019), but in the light of global warming and climate change, it could become established and become an endemic pest in more temperate areas (Nguyen et al, 2019).…”

Nematode samplings in various areas and crops of Greece were carried out and the recovered nematode species were characterized using morphological and molecular data. Seven species of plant-parasitic nematodes were recovered, three of which are reported for the first time in Greece, including Hemicycliophora poranga, Helicotylenchus dihystera and Tylenchorhynchus zeae. Four other recovered species had already been reported in Greece, including Bitylenchus hispaniensis, Helicotylenchus microlobus, Nanidorus minor and Scutellonema brachyurus. D2–D3 segments of 28S rRNA gene for all of these nematode species are provided.

“…Одним из серьезных заболеваний, снижающим урожайность корнеплодов сахарной свеклы, является фитогельминтоз, вызываемый разными вредителямипредставителями типа первичноротых червей нематод (Nematoda) [3,4]. Сахарную свеклу поражает преимущественно свекловичная нематода, представитель вида Heterodera schachtii Schmidt, а также около шести видов галловых нематод рода Meloidogyne ssp., которые вызывают в основном корневое угнетение.…”

Nucleotide substitutions in the resistance gene to root-knot nematodes in sugar beet

et al. 2022

Here we are testing the specific primers NEM06FWD2/NEM06REV2 and nem06FWD1/ nem06REV1 for the R6m-1 resistance gene to root-knot nematodes Meloidogyne spp. in breeding samples of sugar beet. Sugar beet plants of domestic and foreign breeding lines were the object of the study. To identify the relationship between R6m-1 gene, which is localized on the chromosome 1 and controls the stable level of the kinase activity signal, with sugar beet resistance to phytopathogens, PCR-analysis of 10 sugar beet samples were carried out using 2 pairs of molecular genetic markers. DNA amplification revealed a fragments ~500 bp and ~100 bp in length and as a result of sequencing of nucleotide sequences of R6m-1 gene region with subsequent alignment by Geneious Prime program, 3 single nucleotide substitutions (A/G, G/C, and G/A) in the resistant MS11018 genotype and one nucleotide substitution (A/G) and 3 deletions in a foreign hybrid Humber were identified. It can be assumed that these SNPs can form resistance by amino acid substitutions in the polypeptide chain. Finally, possibility to differentiate homozygous and heterozygous genotypes for this allele was shown.

Plant‐parasitic nematodes (PPNs) are one of the most damaging pests to plants and are able to cause significant damage to all parts of plants, including stems, leaves, flowers, fruits and roots. Studies on the diversity, host range, distribution and identification methods of PPNs are therefore vital in order to create a basis for management. This current study represents the first dedicated investigation of PPNs from medicinal plants in Vietnam, focusing on the diversity of nematodes associated with 23 different plant species. In combination with a literature review of PPNs in Vietnam, this work has resulted in an updated list of 217 PPN species belonging to 40 genera, 15 families and three orders and also provides a pictorial online key for the identification of 52 most common and important PPN genera of the world. This key is based on the most crucial diagnostic features of PPN females, including female body shape, cuticle, labial shape, cephalic framework, stylet, stylet base, pharynx, median bulb, pharyngeal gland, vulva, tail shape and phasmid. Pictorial representations of these genera and their diagnostic characters are included in the browser‐based key to benefit users from all levels in nematology, be they beginners or experts.
