Abstract Background The circadian clock is an endogenous mechanism that coordinates biological processes with daily changes in the environment. In plants, rhythms contribute to both agricultural productivity and evolutionary fitness. barley, photoperiod response regulator flowering-time gene Ppd-H1 orthologous Arabidopsis core-clock PRR7 . However, relatively little known about role of other components temperate crop species. this study, we identified barley orthologs tested effects natural...

Abstract Impacts of nine heavy metals (Cd, Cr, Cu, Ni, Pb, K, Fe, Mn, and Zn) contamination in irrigation water on the soil, shoots, roots barely were investigated. Due to freshwater shortages, use available inexpensive urban wastewater with input from local industrial factories containing is still practiced Middle East including Palestine. Barely was grown plastic pots filled sandy soil irrigated simulated treated during two growing seasons. The metal treatments investigated include one,...

The circadian clock is an important timing system that controls physiological responses to abiotic stresses in plants. However, there little information on the effects of stress adaptation crops, like barley. In addition, we do not know how osmotic perceived at roots affect shoot clock. Barley genotypes, carrying natural variation photoperiod response and genes Ppd-H1 HvELF3, were grown under control conditions record changes diurnal expression stress-response traits. Variation HvELF3...

Breeding of high-yielding and stable durum wheat varieties with improved kernel characteristics is needed for dry regions around the globe. The aim this study was to investigate performance stability eight genotypes varying in their across 15 contrasting environments. tested material included three recombinant inbred lines (NUR-072, NUR-106 NUR-238) derived from a cross between Norsi, Jordanian landrace special UC1113

Interest in essential oils was recently revived with their popularity increasing medicine, pharmacy, and aromatherapy. This study performed to identify the chemical compositions of oil Ruta chalepensis growing wildly three regions Palestine assess compare antimicrobial antioxidant activities.Identification by gas chromatography coupled mass spectrometry (GC-MS). Antimicrobial activity tested against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Methicillin-Resistant...

Drought is the major environmental factor limiting wheat production worldwide. Developing novel cultivars with greater drought tolerance most viable solution to ensure sustainable agricultural and alleviating threats food-security. Here we established a core-collection of landraces modern durum (WheatME, n = 36), from Middle East region (Jordan, Palestine Israel) aiming at unlocking genetic morpho-physiological adaptation semi-arid environment conditions. Interestingly, analysis WheatME...

Crop landraces embody a source of beneficial genes potentially providing endurance to environmental stress and other agronomic qualities including yield. Our study included 88 snake melon accessions (Cucumis melo var. flexuosus) collected from 9 districts in the Palestinian West-Bank. These represent four melon: Green, White Baladi, Sahouri.This is first report on successful application genotyping by sequencing melon. Nine thousand seven hundred fifty single-nucleotide polymorphism (SNP)...

This study was conducted to investigate the morphological and agronomical variations among nineteen Palestinian faba bean (Vicia L.) landraces. And analyze their traits including: days flowering, fruit setting, plant height, number of branches on main stem, lowest pod length, width, pods per plant, seeds pod, 100-seed weight total were studied. Significant differences observed genotypes for all characters. The lines clustered into four groups based six agronomic (pod plant). Several could be...

Abstract A set of 23 recombinant lines (RLs) barley ( Hordeum vulgare L.) derived from H. × bulbosum L. crosses was inoculated with leaf rust Puccinia hordei ) and powdery mildew Blumeria graminis f.sp. at the seedling stage to identify their levels mechanisms resistance. Eight RLs were studied further in glasshouse field tests. All three parents (‘Emir’, ‘Golden Promise’ ‘Vada’) highly susceptible isolates. Several showed partial resistance expressed as high relative latency periods low...

Genetic diversity of faba bean genotypes using RAPD markers relatively high collective resolving power (Rp) values 26.316, and varied from 0.154 for the OPA-09 primer to 5.236 BC-261, with an overall mean 2.392.The primers -322, -298 were found be most useful assess genetic Palestinian beans, as they revealed Rp rates (5.236, 3.618, 3.150, respectively).Based on Jaccard coefficient, distance ranged 0.358 0.069, a 0.213.We conclude that technique is determining developing suitable...

Fig mosaic is a viral disease (FMD) that spreads in Palestinian common fig ( Ficus carica L.) orchards. Recognizing the economic value of plants and harmful nature FMD, poses significant threat to economy production Palestine. We applied reverse transcription amplification (RT-PCR) PCR technique leaf samples 77 trees 14 seedlings 17 cultivars. The were collected from orchards main fig-growing provinces West Bank, assess prevalence viruses associated with confirm possible link symptoms...

Background: The experiment was conducted at the Faculty of Agriculture and Veterinary Medicine, An-Najah National University, Palestine under growth chamber greenhouse conditions. Methods: To study effect NaCl on germination, fifty seeds in each treatment for cultivar were germinated a filter paper petri dishes moistened with different concentration levels (0.0, 50 100 mM ). plant productivity, 2 per variety grown 10 liter pots filled peat moss-sand. Pots irrigated levels. Result: tested...

Characterization of fruit species is recognized as a primary and essential step towards protecting, conserving, maintaining, conducting any future breeding program. The aim this study the genetic characterization twelve fig genotypes (Ficus carica L.) from southern region West Bank, Palestine, based on 41 pomological morphological traits developed by IPGRI CIHEAM (2003) with some minor modifications. Results showed considerable diversity among all tested at both levels. UPGMA dendrogram...

Abstract A collection of 111 barley landraces from the Fertile Crescent was screened for resistance to leaf rust in field and under controlled conditions. Large variation observed disease severity Accessions with high because hypersensitivity were identified. Also segregation some accessions, individual plants showing hypersensitive reactions (IT ≤ 6). Partial due a reduction infection spite compatible commonly found (19%). Resistance 12 accessions selected their low IT, shown be prolonged...

Effective microorganisms (EM) are important beneficial fungi and bacteria mixed culture that is used as an inoculant to improve soil quality health, enhance plant growth, yield, quality. This study was conducted evaluate the effect of inoculating various concentration EM (50, 100 200 mL L-1) on growth wheat (Triticum aestivum L.) seedlings, grown under NaCl regime (6 dS m-1), including fresh dry weight, chlorophyll content, maximum fluorescence yield (Fm), variable (Fv), optimum photosystem...

A collection of 418 Spanish barley accessions was screened for resistance to leaf rust in the field at Córdoba, Spain during 2002–2003 season. Six displaying lowest disease severity with no macroscopically visible necrosis were selected further studies on components resistance. Five them showed a significantly higher relative latency period than susceptible line L94 and similar partially resistant Vada. All lower infection frequency smaller colony size under controlled conditions....
