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...

Ribosomal inactivation damages 28S ribosomal RNA by interfering with its functioning during gene translation, leading to stress responses linked to a variety of inflammatory disease processes. Although the primary effect of ribosomal inactivation in cells is the functional inhibition of global protein synthesis, early responsive gene products including proinflammatory cytokines are exclusively ...

background : in this study, we used both its1 and its2 for molecular identification of fasciola species. methods : the region between 18s and 28s of ribosomal dna was used in pcr-rflp method for molecular identification of fasciola species. ninety trematodes of fasciola were collected during abattoir inspection from livers of naturally infected sheep and cattle from khorasan, east azerbaijan, a...

BACKGROUND NIR was identified as an inhibitor of histone acetyltransferase and it represses transcriptional activation of p53. NIR is predominantly localized in the nucleolus and known as Noc2p, which is involved in the maturation of the 60S ribosomal subunit. However, how NIR functions in the nucleolus remains undetermined. In the nucleolus, a 47S ribosomal RNA precursor (pre-rRNA) is transcri...

We characterized a novel 28S rRNA cleavage in cells infected with the murine coronavirus mouse hepatitis virus (MHV). The 28S rRNA cleavage occurred as early as 4 h postinfection (p.i.) in MHV-infected DBT cells, with the appearance of subsequent cleavage products and a decrease in the amount of intact 28S rRNA with increasing times of infection; almost all of the intact 28S rRNA disappeared by...

The second internal transcribed spacer region of the nuclear ribosomal gene cluster (ITS2). This consists three genes (18S rDNA, 5.8S rDNA and 28S rDNA) which have into RNA. Nevertheless, not translated protein. It is sensitive to detect S. scabiei DNA even after treatment. In addition, this can genetic variations species that are related taxonomically. study aimed determine compare sensitivity...

b a ckground : anopheles culicifacies is an important vector of malaria in southeast asia, contributing to almost 70%of malaria cases in india. it exists as a complex of five morphologically indistinguishable species a, b, c, d and e with varied geographical distribution patterns. in india, 8% of the total population of madhya pradesh (central india) contributes about 30% of total malaria cases...

all wasp species in the genus lysiphlebus fã¶rster are solitary endoparasitoids of aphids andconsidered a taxonomically difficult group. in this study a part of coi and its2 was used to distinguishtwo closely related species l. fabarum (marshall) and l. confusus tremblay & eady in iran. thesequencing with a similarity about 99.5% showed coi's inability to separate the species l. fabarum an...

The genetic structure of 23 populations of Graphocephala atropunctata (Signoret) (Hemiptera: Cicadellidae: Cicadellinae), a vector of the plant pathogenic bacterium Xylellafastidiosa Wells et al., was investigated using ribosomal 28S and mitochondrial cytochrome C oxidase I gene sequences. The 28S sequences were identical across all G. atropunctata specimens and populations, but 16 mitochondria...
