Guar is an economically important legume crop that used for gum production. The clean and sustainable production of guar, especially in newly reclaimed lands, requires biofertilizers can reduce the use mineral fertilizers, which have harmful effects on human health environment. present study was conducted to investigate produced from Bradyrhizobium sp., Bacillus subtilis, arbuscular mycorrhizal fungi (AMF), individually or combinations, microbial activity, nutrients soils guar growth seed...
Reducing reliance on fossil fuels with clean and sustainable alternatives is essential for mitigating climate change global warming-related environmental concerns. Previous researchers have studied the performance of choppers crushers as separate units powered by diesel or gasoline engines. Nowadays, an increasing interest in producing Eco-friendly machines that stand out being dual purposes, cost-effectiveness, lengths suitable feeding ruminants are imperative to achieving economic goals....
Abstract Background Root-knot nematodes are sedentary endoparasites that can infect more than 3000 plant species. cause an estimated $100 billion annual loss worldwide. For successful establishment of the root-knot nematode in its host plant, it causes dramatic morphological and physiological changes cells. The expression some genes is altered by as establishes feeding site. Results We examined soybean ( Glycine max ) galls formed roots nematode, Meloidogyne incognita , 12 days 10 weeks...
Regulation of pre-mRNA splicing diversifies protein products and affects many biological processes. Arabidopsis thaliana Serine/Arginine-rich 45 (SR45), regulates by interacting with other regulatory proteins spliceosomal subunits. Although SR45 has orthologs in diverse eukaryotes, including human RNPS1, the sr45–1 null mutant is viable. Narrow flower petals reduced seed formation suggest that genes involved processes, reproduction. To understand how regulation reproductive we studied mRNA...
Agrobacterium spp. are important plant pathogens that the causative agents of crown gall or hairy root disease. Their unique infection strategy depends on delivery part their DNA to cells. Thanks this capacity, these phytopathogens became a powerful and indispensable tool for genetic engineering agricultural biotechnology. Although standard tools molecular biologists, current laboratory strains have remained unchanged decades functional gene analysis has been hampered by time-consuming...
The current study was designed to assess the effect of different concentrations silica oxide nanoparticles (SiO2NPs) (0, 30, 60, and 90 ppm) as foliar applications under three irrigation regimes i.e., every 3 days (IR3, control), 6 (IR6), 9 (IR9) on growth, yield certain metabolites rice (Oryza sativa L. cv. EHR1). To achieve such a goal, 2 field experiments were conducted during 2018 2019 seasons at Experimental Farm Rice Research Training Center (RRTC), Sakha Agricultural Station, Kafr...
The genome of the obligate biotrophic phytopathogenic barley powdery mildew fungus Blumeria hordei is inflated due to highly abundant and possibly active transposable elements (TEs). In absence otherwise common repeat-induced point mutation transposon defense mechanism, noncoding RNAs could be key for regulating activity TEs coding genes during pathogenic life cycle.We performed time-course whole-transcriptome shotgun sequencing (RNA-seq) total RNA derived from infected leaf epidermis at...
Abstract Sclerotinia sclerotiorum is a notorious generalist plant pathogen that threatens more than 600 host plants, including wild and cultivated species. The molecular bases underlying the broad compatibility of S. with its hosts not fully elucidated. In contrast to higher plants animals, alternative splicing (AS) well studied in plant‐pathogenic fungi. AS common regulated cellular process increases cell protein RNA diversity. this study, we annotated spliceosome genes genome characterized...
Abstract Bacterial wilt caused by Ralstonia solanacearum is a devastating disease that often threatens potato production and exportation. The potential of four antioxidants (seaweed extract ( SWE ), yeast, chitosan ascorbic acid ASA )) in controlling the was evaluated vitro , under glasshouse field conditions. experiment conducted two naturally infested locations: Wardan, Giza (sandy soil), Talia, Minufiya (silty clay soil). Only showed antibacterial properties against pathogen . yeast...
Bacillus velezensis is considered as a model species belonging to the so-called subtilis complex that evolved typically dwell in soil rhizosphere niche and establish an intimate association with plant roots. This bacterium provides protection its natural host against diseases represents one of most promising biocontrol agents. However, molecular basis cross talk this establishes has been poorly investigated. We show here these plant-associated bacteria have polymer-sensing system perceive...
Powdery mildew of sweet pepper (Capsicum annuum) is an economically important disease. It caused by Leveillula taurica, obligate biotrophic ascomycete with a partly endophytic mycelium and haustoria, i.e., feeding structures formed in the mesophyll cells infected host plant tissues. The molecular basis its pathogenesis largely unknown because genomic resources only exist for epiphytically growing powdery fungi haustoria exclusively epidermal their hosts. Here, we present first reference...
Abstract Bacteria-derived lipopeptides are immunogenic triggers of host defenses in metazoans and plants. Root-associated rhizobacteria produce cyclic that activate systemically induced resistance (IR) against microbial infection various How these molecules perceived by plant cells remains elusive. Here, we reveal immunity activation Arabidopsis thaliana the lipopeptide elicitor surfactin is mediated docking into specific sphingolipid-enriched domains relies on membrane deformation...

This study was carried out to assess the effect of certain biomodulators, namely seaweed extract, humic acid, peppermint and thyme oils, on quality-related metabolites during both pre-and post-harvest Red radish.For this purpose, plants were sprayed with tested biomodulators twice, 20 30 days after sowing, chosen biochemical constituents affecting quality estimated before harvest, again in roots harvested storage standard cold storage.In addition, evaluate involvement each parameter stored...
Trade-offs between growth and reproduction in soybean require resource availability manipulations. Decapitation reducing sink strength through deflowering can affect the source–sink ratio that affects plant growth, development, yield. The current study assesses effect of decapitation (Decap) removal two lowest racemes (R2LR) their combination on flowering, yield capacity controlling inducing “stay-green” phenotype. Two field experiments were conducted during 2018 2019 Agronomy Farm located...
Background The thyroid gland is responsible for regulating many aspects of body functions. Despite their global prevalence, disorders often go underdiagnosed, which can lead to serious health complications. In Saudi Arabia, the overall prevalence was 49.76%, among subclinical hypothyroidism most prevalent type. Raising awareness and knowledge about diseases risk factors essential prevention early treatment these disorders. Aim objectives To assess residents Jeddah, as well understand...
Acid sulfate soils pose significant challenges to rice production due their negative impact on root development and nutrient uptake, reducing yield quality. The excessive use of fungicides by farmers control diseases has exacerbated the issue, as it contributes environmental pollution poses health risks.
