Genome-Wide Association Study of Rice Diversity Panel Reveals New QTLs for Tolerance to Water Deficit Under the Egyptian Conditions.

Drought has a significant impact on rice yield by restricting the crop's ability to grow and develop. Producing rice cultivars adapted to water deficit conditions is still the main interest of rice breeders and geneticists. To address this challenge, a set of 413 highly diverse rice populations were evaluated under normal and water deficit conditions for two growing seasons of 2021 and 2022.

Exploring Genetics by Environment Interactions in Some Rice Genotypes across Varied Environmental Conditions.

Rice production faces challenges related to diverse climate change processes. Heat stress combined with low humidity, water scarcity, and salinity are the foremost threats in its cultivation. The present investigation aimed at identifying the most resilient rice genotypes with yield stability to cope with the current waves of climate change.

Impacts of kinetin implementation on leaves, floral and root-related traits during seed production in hybrid rice under water deficiency.

Background: Water deficit is one of the most significant abiotic factors affecting rice and agricultural production worldwide. In hybrid rice, cytoplasmic male sterility (CMS) is an important technique for creating high-yielding crop based on heterosis. The phytohormone kinetin (Kin) regulates cell division in plant during the early stages of grain formation, as well as flow assimilation and osmotic regulation under water stress.

Microscopic Study of Mechanoreceptors and Chemoreceptors of Anterior and Posterior Ends of Toxocara Canis Using Scanning Electron Microscopy and Light Microscope.

The present study investigated the fine structure of amphids and phasmids, cuticle, muscles, and digestive tracts of Toxocara canis using optical and electron microscopy, hematoxylin-eosin (H&E) staining, and other specific stains. A number of 38 adult T.canis worms were obtained from the animal shelter of Urmia, and their small intestines were fixated in acidified formal alcohol and 10% formalin solutions.

Morphologic and molecular analysis of species from Iranian native sheep.

is a worldwide parasitic disease of ruminants which affects the liver. In this current study, the phylogenic pattern of species in Iranian native sheep from three different geographical regions was investigated by investigating a 520 bp fragment of mitochondirial NAD1 gene. The analysis of the NAD1 oligo nucleotide sequences from 10 (GenBank accession numbers: MG889399 to MG889408) revealed few non-significant differences, suggesting limited application for NAD1 gene as a biomarker for study of genetic variation in .
