The effect of foliar application of zinc oxide nanoparticles and Moringa oleifera leaf extract on growth, biochemical parameters and in promoting salt stress tolerance in faba bean

Salinity is major abiotic stress limiting plant growth worldwide. Plant adaptation to salinity stress involves diverse physiological and metabolic pathways. In this study, we assessed the effects of foliar application of zinc oxide nanoparticles (ZnONPs) and Moringa leaf extract (MLE) on salt tolerance in faba beans (cultivar, Sakha 4). Morphological, chemical, and biochemical parameters of plants grown under saline...

Modulation of ethoxyresorufin-o-deethylase, benzoxyresorufin-o-dealkylase and pentoxyresorufin-o-dealkylase expression by African walnut seeds lipid extract in 3-methylcholanthrene induced breast cancer in Wistar rats

Breast cancer is prevalent among women worldwide. African walnut (Tetracarpidium conophorum) seeds extract have been shown to have medicinal properties. This study is to determine the effects of feeding T. conophorum seeds lipid extract on 3-methylcholanthrene (MC) induced breast carcinogenesis and the expression of ethoxyresorufin-O-deethylase (CYP1A1), benzoxyresorufin-O-dealkylase (CYP1B1) and...

Assessment of genetic diversity of local rice accessions cultivated in Guinea revealed by SNPs markers, and identification of markers associated with tolerance to iron toxicity

Rice is the staple food in the Republic of Guinea. However, its production is seriously hampered by iron toxicity. The fight against this stress necessarily involves the search for tolerant or resistant varieties. The study aims to determine quantitative trait locus (QTL) associated with tolerance to iron toxicity and to identify genotypes tolerant or resistant to iron toxicity. Thus, 90 local rice accessions collected...

The role of N-terminal module of PhyB in modulating root and hypocotyl growth length in Arabidopsis

Phytochrome belongs to red/far-red light family of photoreceptors. It exists in two spectral forms named red light absorbing form (Pr), said to be the inactive form and far-red light absorbing form (Pfr) which is the active form. This photoreceptor is structurally divided into two modules- the amino acid (N-) terminal photosensory module and caboxylic acid (C-) terminal His kinase-like catalytic output module. Five...

The effect of substrates on the growth, yield, nutritional and phytochemical components of Pleurotus ostreatus supplemented with four medicinal plants

The aim of this study was to investigate the effect of substrates on the growth, yield, nutritional, and medicinal value of Pleurotus ostreatus supplemented with four medicinal plants. A completely randomized block design was laid out with 4 treatments replicated 4 times with and without medicinal plants. T1 (sawdust), T2 (sawdust + corncobs), T3 (palm cones), and T4 (elephant stalks) were the treatments used. Croton...
