The beet cyst nematode, Heterodera schachtii, is a major root pest that significantly impacts the yield of sugar beet, brassicas and related species. There has been limited molecular characterisation of this important plant pathogen: to identify target genes for its control the transcriptome of the pre-parasitic J2 stage of H. schachtii was sequenced using Roche GS FLX. Ninety seven percent of ...

Pearl millet (Pennisetum glaucum) is a drought-tolerant cereal commonly grown for grain and fodder in arid areas throughout the world. Senegalese millet fields are infested with Helicotylenchus. The native evergreen woody shrub Piliostigma reticulatum is widely distributed in sub-Saharan Africa. Its coppiced residues are used by small farmers as mulch in crop fields. The shrub's nematicidal eff...

Meloidogyne graminicola is one of the most economically important plant parasitic-nematodes (PPNs). In the present study, we determined the complete mitochondrial (mt) DNA genome sequence of this plant pathogen. Compared with other PPNs genera, this genome (19,589 bp) is only slightly smaller than that of Pratylenchus vulnus (21,656 bp). The nucleotide composition of the whole mtDNA sequence of...

Like other biotrophic plant pathogens, plant-parasitic nematodes secrete effector proteins into host cells to facilitate infection. Effector proteins that mimic plant CLAVATA3/ENDOSPERM SURROUNDING REGION-related (CLE) proteins have been identified in several cyst nematodes, including the potato cyst nematode (PCN); however, the mechanistic details of this cross-kingdom mimicry are poorly under...

The genus Heterodera consists of 80 valid species which are distributed all over the world and they range from mono to polyphagous (Subotin et al., 2010). Several species are considered economically important (or quarantine), including H. humuli Filipjev, 1934. Previous studies on H. humuli or H. humuli as a vector of plant viruses were focused on its geographical distribution, biology, life cy...

Abstract The ryegrass cyst nematode, Heterodera mani , is reported from Western Australia for the first time. Cysts were recovered soil samples collected on a broadacre cropping property near town of Esperance. production area dominated by cereal/oilseed rotation and species annual ( Lolium rigidum ) common weed issue in these paddocks. Morphometrics cysts second stage juveniles (J2s) Australia...

Kentang merupakan salah satu komoditas penting dan mendapat prioritas untuk dikembangkan di Indonesia karena potensi ekspor yang tinggi ke negara lain. Salah hambatan dalam peningkatan produksi tanaman kentang yaitu adanya serangan nematoda sista (NSK). Penelitian ini bertujuan mengetahui keberadaan NSK pada lahan Desa Sumber Brantas, Kecamatan Bumi Aji, Kota Batu, Provinsi Jawa Timur. dilakuka...

Mung bean residues stimulate the hatching of soybean cyst nematode (SCN). In our previous study, combined incorporation mung and biochar into soil can be effective in suppression (SCN), Heterodera glycines, upper layer soil. However, there are no data available as to whether such effects transmissible, could for example manifest subsoil zones where is confined topsoils, via water-based pathways...
