Morphological and Biochemical Changes in the Mediterranean Cereal Cyst Nematode () during Diapause.

The cereal cyst nematode () is becoming an economically important species in global cereal production as it is being identified in many new cereal cultivated areas and causes significant losses. Consequently, understanding its biology becomes crucial for researchers in identifying its vulnerabilities and implementing effective control measures. In the current study, different morphological and biochemical changes of cysts containing eggs with infective juveniles from a barley field in Jordan were studied during the summer of 2021, at two sample dates.

Bioinformatics analysis of ubiquitin expression protein gene from .

Ubiquitin expression protein DNA clone (Hl-UBI) was isolated from collected from North Jordan. Its sequence of 285 nucleotides was also determined and deposited in the GeneBank. The 285-bp open reading frame coded for 76-amino acid protein having two domains; the ubiquitin domain and the C terminal extension.

Draft Genome Sequence of the Plant Growth-Promoting Pseudomonas punonensis Strain D1-6 Isolated from the Desert Plant Erodium hirtum in Jordan.

Pseudomonas punonensis strain D1-6 was isolated from roots of the desert plant Erodium hirtum, near the Dead Sea in Jordan. The genome of strain D1-6 reveals several key plant growth-promoting and herbicide-resistance genes, indicating a possible specialized role for this endophyte.

Morphological and morphometrical analysis of Heterodera spp. populations in Jordan.

Phenotypic diversity of five Jordanian populations of cyst nematodes, Heterodera spp. collected from five regions from Jordan (Ar-Ramtha, Madaba, Dana, Al-Karak, and Jerash) was investigated. Soil samples were collected from one representative field in each region.

Phosphonate fertilizers suppressed root knot nematodes Meloidogyne javanica and M. incognita.

The efficacy of the phosphonate fertilizers, Calphos(®) (a.i. calcium phosphonate), Magphos(®) (a.

Array CGH identifies reciprocal 16p13.1 duplications and deletions that predispose to autism and/or mental retardation.

Autism and mental retardation (MR) are often associated, suggesting that these conditions are etiologically related. Recently, array-based comparative genomic hybridization (array CGH) has identified submicroscopic deletions and duplications as a common cause of MR, prompting us to search for such genomic imbalances in autism. Here we describe a 1.

Discrimination of six pratylenchus species using PCR and species-specific primers.

A PCR-based assay for identification of six species of Pratylenchus common in California is described. In this assay, five forward species-specific primers were designed from the internal variable portion of the D3 expansion region of the 26S rDNA and were each used with a single, common reverse primer. The optimized species-specific primers produced unique amplicons from their respective target and did not amplify DNA from other Pratylenchus species.

Characterization of Otostrongylus circumlitus from Pacific harbor and northern elephant seals.

Otostrongylus circumlitus (Railliet, 1899) from Pacific harbor seals (Phoca vitulina richardsi) and northern elephant seals (Mirounga angustirostris) were examined using morphological and molecular methods to determine whether northern elephant seals along the central California coast are infected by the same species of Otostrongylus as are Pacific harbor seals in the same area. Fixed nematodes were examined and measured using light microscopy. The polymerase chain reaction (PCR) was used to amplify and sequence the second internal transcribed spacer (ITS-2) and D3 expansion (26S) regions of ribosomal DNA of O.

Phylogenetic analysis of nematodes of the genus Pratylenchus using nuclear 26S rDNA.

We used nucleotide sequences of the large subunit ribosomal genes (26S rDNA) to examine evolutionary relationships among species of the genus Pratylenchus (Order: Tylenchida, Family: Pratylenchidae), commonly known as root-lesion nematodes. Ten species of Pratylenchus were studied including, P. penetrans, P.

A new species of Vexillata (Nemata: Ornithostrongylidae) from the coarse-haired pocket mouse Chaetodipus hispidus in New Mexico.

Individuals of a new species of trichostrongyloid nematode of the genus Vexillata were collected from the intestines of the coarse-haired pocket mouse Chaetodipus hispidus from eastern New Mexico. This new species possesses general features of the genus Vexillata but may be recognized as distinct from all other species by unique features of the dorsal ray of the caudal bursa and the synlophe.
