Gamma-Aminobutyric Acid (GABA) as a Defense Booster for Wheat against Leaf Rust Pathogen ().

Wheat leaf rust, caused by , poses a growing threat to global wheat production, necessitating alternative strategies for effective disease management. This study investigated the potential of gamma-aminobutyric acid (GABA) to enhance resistance to leaf rust in two wheat cultivars: the susceptible Morocco and moderately resistant Sakha 94 cultivar. Our findings revealed that GABA significantly improved resistance in both cultivars to , particularly in Morocco, by mitigating disease severity and reducing pustule density and size while extending both incubation and latent periods.

Bioethanol Production from Characterized Pre-treated Sugarcane Trash and Jatropha Agrowastes.

Low production costs and a potential feedstock supply make lignocellulosic ethanol (bioethanol) an important source of advanced biofuels. The physical and chemical preparation of this kind of lignocellulosic feedstock led to a high ethanol yield. In order to increase the yield of fermentable sugars, pretreatment is an essential process step that alters the lignocellulosic structure and improves its accessibility for the expensive hydrolytic enzymes.

Intra-oral Drainage of Submandibular Abscess: A Minimally Invasive Technique. A Prospective Study.

Purpose: To evaluate the efficacy of intraoral drainage of isolated submandibular space abscess as a minimally invasive surgical technique compared to the standard trans-cervical approach.

Patients And Methods: This prospective study included 40 subjects with isolated submandibular space abscesses. They were randomly divided into 2 equal groups: trans-cervical surgical drainage (group A) and intra-oral surgical drainage (group B).

Assessment of Occult Nodal Micrometastases to the Clinically Negative Contralateral Neck in Locally Advanced Supraglottic Squamous Cell Carcinoma.

The aim of this study is  to study the incidence of occult nodal micrometastases (ONM) in the contralateral neck and compare it to the laterality of the primary tumor. Retrospective analysis of the medical records of patients with locally advanced supraglottic squamous cell carcinoma and Clinically negative contralateral neck (cN0-CLN) - who had concurrent total laryngectomy and bilateral neck dissection as their primary treatment at the Otolaryngology Department, Al Kas Al Ainy School of Medicine-Cairo University between 2015 and 2020 - was conducted. Patients were divided into 3 groups according to the extent of the primary tumor.

Phenotyping and validation of molecular markers associated with rust resistance genes in wheat cultivars in Egypt.

Background: Thirteen Egyptian wheat cultivars were evaluated and characterized for adult plant resistance to yellow, leaf, and stem rusts. SSR markers linked to yellow, leaf and stem rust resistance genes were validated and subsequently used to identify wheat cultivars containing more than one rust resistance gene.

Results: Results of the molecular marker detection indicated that several genes, either alone or in different combinations, were present among the wheat cultivars, including Yr, Yr78 (stripe rust), Lr, Lr70 (leaf rust), Sr.

Genetic diversity, antifungal evaluation and molecular docking studies of Cu-chitosan nanoparticles as prospective stem rust inhibitor candidates among some Egyptian wheat genotypes.

Wheat has a remarkable importance among cereals worldwide. Wheat stem and leaf rust constitute the main threats that destructively influence grain quality and yield production. Pursuing resistant cultivars and developing new genotypes including resistance genes is believed to be the most effective tool to overcome these challenges.

Mining of Leaf Rust Resistance Genes Content in Egyptian Bread Wheat Collection.

Wheat is a major nutritional cereal crop that has economic and strategic value worldwide. The sustainability of this extraordinary crop is facing critical challenges globally, particularly leaf rust disease, which causes endless problems for wheat farmers and countries and negatively affects humanity's food security. Developing effective marker-assisted selection programs for leaf rust resistance in wheat mainly depends on the availability of deep mining of resistance genes within the germplasm collections.

Genomic regions associated with stripe rust resistance against the Egyptian race revealed by genome-wide association study.

Background: Wheat stripe rust (caused by Puccinia striiformis f. sp. Tritici), is a major disease that causes huge yield damage.

Pathogenic variation in isolates of Pseudomonas causing the brown blotch of cultivated mushroom, Agaricus bisporus.

Twenty seven bacterial isolates were isolated from superficial brown discolorations on the caps of cultivated Agaricus bisporus. After White Line Assay (WLA) and the assist of Biolog computer-identification system, isolates were divided into groups: (I) comprised ninteen bacterial isolates that positively responded to a Pseudomonas "reactans" reference strain (NCPPB1311) in WLA and were identified as Pseudomonas tolaasii, (II) comprised two isolates which were WLA+ towards the reference strain (JCM21583) of P. tolaasii and were proposed to be P.
