Macrofungi from the Hebron and Jerusalem Hills of Palestine
(2020)This study is based on specimens of macrofungi collected from biodiversity hotspots in the southern West Bank of occupied Palestine during a four-week survey period in December and January 2018–19. We identified 27 macrofungi ... -
Making a friend from a foe: expressing a GroEL gene from the whitefly Bemisia tabaci in the phloem of tomato plants confers resistance to tomato yellow leaf curl virus
(Archives of Virology, 2007-03-05)Some (perhaps all) plant viruses transmitted in a circulative manner by their insect vectors avoid destruction in the haemolymph by interacting with GroEL homologues, ensuring transmission. We have previously shown that ... -
Mantids (Dictyoptera: Mantodea) from the Palestinian Territories with an updated list
(ARTICULATA, 2018)A total of seventeen species of the order Mantodea were recorded from the Palestinian Territories belonging to five families (Empusidae, Eremiaphilidae, Mantidae, Tarachodidae and Toxoderidae) and thirteen genera (Ameles, ... -
Mapping of novel salt tolerance QTL in an Excalibur × Kukri doubled haploid wheat population
(Springer Berlin Heidelberg, 2018-10-01)Key message Novel QTL for salinity tolerance traits have been detected using non-destructive and destructive phe notyping in bread wheat and were shown to be linked to improvements in yield in saline fields. Abstract ... -
Mapping of novel salt tolerance QTL in an Excalibur× Kukri doubled haploid wheat population
(Springer, 2017-07)Novel QTL for salinity tolerance traits have been detected using non-destructive and destructive phenotyping in bread wheat and were shown to be linked to improvements in yield in saline fields. Abstract Soil salinity ... -
Molecular Identification of Six Steinernema Isolates and Characterization of their Internal Transcribed Spacers Regions
(2013-11-14)Molecular identification and genotyping of entomopathogenic nematodes (EPNs) are prerequisites for their proper classification, biodiversity studies, and their potential use in biological control programs. In Palestine, ... -
A novel double-stranded RNA mycovirus from Fusarium graminearum; Nucleic acid sequence and genomic structure.
(Archives of Virology, 2011-01-07)Ten Fusarium graminearum isolates from China were screened for dsRNA mycoviruses. Five dsRNAs (2.4 to 3.5 kbp) were purified from isolate China 9, cloned, and sequenced. BLAST analysis showed that the proteins encoded by ... -
Optimal designs for contingent response models
(Springer, 2004)We study D- and c-optimal designs for the contingent response models of (1995). In the contingent response model there are two types of failure. We call one failure type toxicity and the other disease failure. No toxicity ... -
Optimal designs for contingent response models with application to toxicity and efficacy
(Issac Newton Institute for Mathematical Sciences, 2011-12)We generalize results in the literature to obtain a general family contingent response models. These models have ternary outcomes constructed from two Bernouli outcomes, where one outcome is only observed if the other ... -
Optimal designs for contingent response models with application to toxicity–efficacy studies
(Springer Science & Business Media, 2012)We describe a general family of contingent response models. These models have ternary outcomes constructed from two Bernoulli outcomes, where one outcome is only observed if the other outcome is positive. This family is ... -
Optimal designs for dose-finding in contingent response models
(University of Missouri--Columbia, 2004-12)We study D- and c-optimal designs for dose-finding with opposing failure functions. In particular, we study the contingent response models of Li, Durham and Flournoy (1995). In the contingent response model, there are two ... -
Optimized approaches for the sequence determination of double-stranded RNA templates
(Journal of Virological Methods, 2010-08-18)Double-stranded RNA (dsRNA) is in many cases the only available template for molecular and diagnostic studies of RNA viruses. A novel mycovirus with a five dsRNAs segmented-genome served as a model system for the ... -
Preparation of Novel Cyanoguanidine Derivatives of Tryptamines
(Thieme, 2001)A new class of cyanoguanidine derivatives bearing a tryptamine moiety was prepared by a three-step reaction sequence. The preparation of the starting materials and characterization of the intermediates are also described. -
A QTL on the short arm of wheat (Triticum aestivum L.) chromosome 3B affects the stability of grain weight in plants exposed to a brief heat shock early in grain filling
(BioMed Central, 2016)Background: Molecular markers and knowledge of traits associated with heat tolerance are likely to provide breeders with a more efficient means of selecting wheat varieties able to maintain grain size after heat waves during ... -
Rearrangement of Allyl Aryl Ethers II, Reactions of Hydroquinones with Cycloalkenediols
(Thieme, 1997)Cycloalkenobenzofurans are prepared in one operation from hydroquinone and cycloakenediol involving a sequence of acid-catalyzed formation of ether , 1,3- and 3,3-rearrangements, and acid-catalyzed intramolecular cyclization ... -
Rearrangement of Allyl Aryl Ethers III, Reactions of Alkoxyhydroquinones with Cycloalkenediols
(Elsevier, 1997)Cycloalkenobenzofurans were prepared in one-pot reaction from methoxyhydroquinone, 2,5- and 2,6 and 2,3- dialkoxyhydroquinone with cycloalkenediol. Reaction between isomeric 2,5- dialkoxyhydroquinone with diol led to the ... -
Records of scorpions from the Palestinian Territories, with the first chromosomal data (Arachnida: Scorpiones)
(Zoology in the Middle East, 2013)Seven species were collected from several habitats in the West Bank, namely Leiurus quinquestriatus, Androctonus crassicauda, Compsobuthus werneri, Orthochirus scrobiculosus, Hottentotta judaicus, Nebo hierichonticus, ...
