The properties of nanomaterials and their potential applications have been given considerable attention by researchers in various fields, especially agricultural biotechnology. However, not much has done to evaluate the role or effect zinc oxide nanoparticles (ZnO-NP) regulating physiological biochemical processes response salt-induced stress. For this purpose, some callus growth traits, plant regeneration rate, mineral element (sodium, potassium, phosphorous nitrogen) contents changes...

Ethnobotanical and phytochemical studies are useful to discover new drugs. Phytochemical screening is an important step in the detection of bioactive components existing medicinal plants that used traditional medicine. Very few investigating medicine exist Saudi Arabia. Eighty-five Jeddah, Arabia investigated here for first time. This research aims screen 85 Jeddah presence secondary metabolites, answer following question: Is ethnomedicinal importance conform their metabolite content....

Defining and recognizing a species has been controversial issue for long time. To determine the variation limitation between species, many concepts have proposed. When taxonomist study particular taxa, he/she must adopted concept provide to define this taxa. In paper some of are discussed starting from typological phylogenetic concept. Positive negative aspects these represented in addition their application.

Five cultivars of tomato having different levels salt stress tolerance were exposed to treatments NaCl (0, 3 and 6 g L-1) ZnO-NPs 15 30 mg L-1). Treatments with at both L-1 suppressed the mRNA superoxide dismutase (SOD) glutathione peroxidase (GPX) genes in all while plants treated presence NaCl, showed increments expression levels. This indicated that had a positive response on plant metabolism under stress. Superior observed tolerant cultivars, Sandpoint Edkawy lowest level was detected...

Soil erosion is one of the major environmental problems in terms soil degradation Saudi Arabia. leads to significant on- and off-site impacts such as decrease productive capacity land sedimentation. The key aspects influencing quantity mainly rely on vegetation cover, topography, type, climate. This research studies quantification under different levels data availability Wadi Yalamlam. Remote Sensing (RS) Geographic Information Systems (GIS) techniques have been implemented for assessment...

Very few studies examining quantitatively gender differences in the knowledge and use of medicinal plants exist for Arab world. Differences ethnobotanical between men women Jeddah are explored here first time.Our study aims to document urban plant Jeddah, answer following questions: (1) What used by Saudis Jeddah? (2) To what extent do plants? (3) Are significantly different those women? And, (4) learn about ways? Given gendered nature space relations world, we hypothesise that ways this...

Abstract. Wadi Yalamlam is known as one of the significant wadis in west Saudi Arabia. It a very important water source for western region country. Thus, it supplies holy places Mecca and surrounding areas with drinking water. The floristic composition has not been comprehensively studied. For that reason, this work aimed to assess wadi vegetation cover, life-form presence, chorotype, diversity, community structure using temporal remote sensing data. Temporal datasets spanning 4 years were...

Fig leaf mottle-associated virus-1 (FLMaV-1) is a closterovirus newly identified in fig trees, the Mecca region, suffering from mosaic disease symptoms and apparently compromising plantation country. In present study, we demonstrated efficiency of two vivo experiments including pre post treatments using Thuja leaf, ginger roots, Harmal seeds turmeric rhizome extracts on expression rooted cuttings infected with FLMaV-1- their impact virus multiplication. Results showed that individual roots...

Abstract Background Phoenix dactylifera L. belongs to the subfamily Coryphoideae. Saudi Arabia is third producing country of dates in world with over a million tons every year. P. one most important species that grows Al-Madinah and has cultivars are distinguished by their appearance taste. Results This study aimed investigate importance morphology among using statistical analysis ability identify just looking at them obvious characters palms. Plant specimens were collected from different...

Many diseases are compromising fig production in Saudi Arabia and particular those caused by viruses. RT-PCR assays were conducted on 80 samples collected from four fig-growing provinces the West Mecca region of Arabia, including Fatima, Khulais, Rabigh Alshifa valleys. Samples consisted leaf tissues taken caprifig common trees. The presence Fig mosaic virus (FMV), mottle-associated 1 (FLMaV-1), 2 (FLMaV-2) mild (FMMaV) was assessed samples. results showed that all viruses present surveyed...

More than 100 alkaloids have been found in periwinkle, of which vincristine and vinblastine are the most notable for treatment diseases such as leukaemia. In this study, characterization naturally occurring Cucumber mosaic virus (CMV) infection showed mosaic, leaf deformation stunting plants. Viral identification was confirmed by double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) with a specific CMV polyclonal antibody reverse transcription PCR primer CMV-RdRp-gene,...

Very few phytochemical studies based on ethnobotanical were conducted in Saudi Arabia. In Jeddah, medicinal plants play a major role healthcare. Here and for the first time, chemical reasons behind use of 5 folk medicine Jeddah to treat respiratory diseases highlighted. Objective: The current research aims investigate composition commonly used by analysis methods High-performance liquid chromatography (HPLC) with Gas chromatography-mass spectrometry (GC-MS) analysis. Material methods: Based...

Abstract Classification is the science that arranges organisms in groups according to their similarities and differences. In plant science, there are many aspects of classifications. For instance, morphological, anatomical, palynological, molecular, chemical classification. All these types consume time, effort, money. this research, new technology tested identify differences between plants. Spectroradiometer will help classifying Prosopis juliflora (Sw.) DC Bahrah region Saudi Arabia....

Periwinkle ( Catharanthus roseus L.) is an ornamental plant widely grown in the Mecca region Kingdom of Saudi Arabia (KSA). Different symptoms similar to those induced by viruses (mosaic, vein clearing, mottling, yellowing, flower variegation) prompted surveys eight different regions KSA assess presence periwinkle-infecting viruses, i.e. Tomato spotted wilt virus (TSWV), Cucumber mosaic (CMV), Lettuce (LMV), (CatMV) and yellow (CYMV). Two hundred forty leaf samples were collected from...

In deserted conditions, plants suffer from shortage of water and minerals. Though, they try to adapt with harsh conditions by building an internal defense system via making different chemical compounds, especially secondary metabolites. These metabolites have several medicinal effect. Saudi Arabia is considered as semi-arid region. Therefore, it has many high adaptation level survive in the exotic environment.  South west richest plant biodiversity. One common that grows nearly...

The biodiversity of medicinal plants have many economic importances and improve human health.Many biologically active compounds were isolated from that traditionally used in folkloric medicine .These can be either a new drug or base for drug.The antibacterial activity the Cymbopogon schoenanthus Senna holosericea, collected Alabwa region, Saudi Arabia was determined using agar well diffusion method.The collected, identified extracted both different organic solvents (methanol, ethanol...

Periwinkle (Catharanthus roseus L.) grown in the Mecca region contains more than 100 alkaloids such as vincristine and vinblastine used to treat leukaemia.
