Antibacterial, Antioxidant Activities, GC-Mass Characterization, and Cyto/Genotoxicity Effect of Green Synthesis of Silver Nanoparticles Using Latex of Cynanchum acutum L

open access: yesPlants, 2022
Green synthesis of nanoparticles is receiving more attention these days since it is simple to use and prepare, uses fewer harsh chemicals and chemical reactions, and is environmentally benign.

DNA changes in cotton (Gossypium hirsutum L.) under salt stress as revealed by RAPD marker

open access: yesAdvances in Horticultural Science, 2016
Random amplified polymorphic DNA (RAPD) analysis was applied to evaluate DNA changes among four upland cotton (Gossypium hirsutum L.) varieties [Niab 78 (N78), Deir-Ezzor 22 (DE22), Deltapine 50 (DP50) and Aleppo 118 (A118)] grown under non-saline ...

Genotoxic potentials of some selected heavy metals exposure on Clarias gariepinus (Burchell, 1822) and Oreochromis niloticus (Linnaeus, 1758) using RAPD-PCR technique

open access: yesAceh Journal of Animal Science, 2022
Fish health and the aquatic ecosystem are strongly interwoven and interrelated. The aquatic ecosystem receives a range of anthropogenic chemicals which have toxicological or lethal health effects on the aquatic animals.

ASSESSMENT OF LEAD STRESS USING GENOME TEMPLATE STABILITY IN Hordeum vulgare

open access: yesEgyptian Journal of Genetics and Cytology, 2016
Assement of genotoxins-induced DNA damage at molecular level is important in eco-genotoxicology. In this research, ISSR and SRAP were used to detect DNA damage in barley (Hordeum vulgare L.) seeding exposed to toxic ascending Pb at concentration of 50,100, and 150 mg/l for 15 days.

Transcription-Replication Collisions—A Series of Unfortunate Events

open access: yesBiomolecules, 2021
Transcription-replication interactions occur when DNA replication encounters genomic regions undergoing transcription. Both replication and transcription are essential for life and use the same DNA template making conflicts unavoidable.

Accurate protein stability predictions from homology models

open access: yesComputational and Structural Biotechnology Journal, 2023
Calculating changes in protein stability (ΔΔG) has been shown to be central for predicting the consequences of single amino acid substitutions in protein engineering as well as interpretation of genomic variants for disease risk.

Determination of the DNA changes in the artichoke seedlings (Cynara scolymus L.) subjected to lead and copper stresses

open access: yesPlant, Soil and Environment, 2016
This study aims at determining the effects of lead (Pb) and copper (Cu) on the hyperaccumulator artichoke. The effect of Pb and Cu toxicity with different levels of concentrations (20, 40, 80, 160, 240, 320, 640 and 1280 ppm) caused a decrease in the ...

Application of Zinc Oxide Nanoparticles and Plant Growth Promoting Bacteria Reduces Genetic Impairment under Salt Stress in Tomato (Solanum lycopersicum L. ‘Linda’)

open access: yesAgriculture, 2020
Salinity is an edaphic stress that dramatically restricts worldwide crop production. Nanomaterials and plant growth-promoting bacteria (PGPB) are currently used to alleviate the negative effects of various stresses on plant growth and development.

Genetic analysis for identification, genomic template stability in hybrids and barcodes of the Vanda species (Orchidaceae) of Thailand

open access: yesAFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
Molecular data supporting morphological characters for identification and specific markers for ornamental Vanda species in Thailand can be achieved for economic means. The ten native Thai species that have been explored and identified are Vanda bensonii, Vanda brunnea, Vanda coerulea, Vanda coerulescens, Vanda denisoniana, Vanda pumila, Vanda lilacina,
