Impatiens necrotic spot virus (INSV), family Bunyaviridae, genus Tospovirus, is an emerging virus found mostly in ornamentals under greenhouse production. INSV has been detected in peanut (Arachis hypogaea L.) in Georgia and Texas (3) and recently in tobacco (Nicotiana tabacum L.) in the
Guttation, the loss of water and dissolved materials from uninjured plant organs, is a common phenomenon in higher plants. By using endoplasmic reticulum signal peptides fused to the recombinant protein sequences, we have generated transgenic tobacco (Nicotiana tabacum L. cv Wisconsin) plants that
Cucumber mosaic virus (CMV) causing mosaic, leaf distortion and stunting of vanilla (Vanilla planifolia Andrews) in India was characterized on the basis of biological and coat protein (CP) nucleotide sequence properties. In mechanical inoculation tests, the virus was found to infect members of
Biosynthesis of ent-kaurene was investigated in extracts of cell suspension cultures derived from tobacco callus (Nicotiana tabacum L.), tomato callus (Solanum lycopersicum L.), and in germinating tomato seeds. Incubation of extracts derived from the two cell cultures with either isopentenyl
In this report we describe an enzyme-linked immunosorbent assay (ELISA) for the quantitation of abscisic acid (ABA) in plant extracts. A microtitration plate is coated with an ABA-protein complex. The ABA, standard or sample, is then added to each well with a limiting quantity of rabbit anti-ABA
Plant chloroplasts are promising vehicles for recombinant protein production, but the process of protein folding in these organelles is not well understood in comparison with that in prokaryotic systems, such as Escherichia coli. This is particularly true for disulphide bond formation which is
Previous studies with Paenibacillus lentimorbus B-30488" (hereafter referred as B-30488), a plant growth promoting rhizobacteria (PGPR) isolated from cow's milk, revealed its capabilities to improve plant quality under normal and stress conditions. Present study investigates its potential as a
The hepatoprotective effect of the boiled and non-boiled aqueous extracts of Pistacia lentiscus, Phillyrea latifolia, and Nicotiana glauca, that are alleged to be effective in the treatment of jaundice in Jordanian folk medicine, was evaluated in vivo using carbon tetrachloride (CCl(4)) intoxicated
Genetically engineered chloroplasts have an extraordinary capacity to accumulate recombinant proteins. We have investigated in tobacco (Nicotiana tabacum) the possible consequences of such additional products on several parameters of plant development and composition. Plastid transformants were
Barley yellow streak mosaic virus (BaYSMV) was first described and reported in Montana and Alberta, Canada, more than 17 years ago (1). Since then, it has been detected in two other locations: Pocatello Valley, ID (3), and across the border in Utah. BaYSMV has now been found in the Alaskan interior.
A monoclonal antibody (mAb 2A) able to react against the RNA replicase NIb from plum pox virus (PPV) was obtained and used for generating a specific scFv fragment. The VH and VL coding sequences were cloned and expressed as a fusion scFv protein to alkaline phosphatase. This fusion protein was able
Human papillomaviruses (HPV) cause cervical cancer and have recently also been implicated in mouth, laryngeal and anogenital cancers. There are three commercially available prophylactic vaccines that show good efficacy; however, efforts to develop second-generation vaccines that are more affordable,
'Candidatus Liberibacter solanacearum' (Lso) is a plant pathogen affecting Solanaceae and Apiaceae in different parts of the world. 'Candidatus Liberibacter solanacearum' is a gram negative, fastidious α-proteobacterium that is vectored by different psyllid species. Plant pathogenic bacteria are
