Thornberry, H. H. (University of Illinois, Urbana, Ill.) and B. B. Nagaich. Stability of tobacco-mosaic virus, Marmor tabaci H, in solutions diluted beyond the end point of infectivity. J. Bacteriol. 83:1322-1326. 1962.-Tobacco-mosaic virus (TMV) in crude plant extract and in a partially purified
To investigate the transcriptional regulation of gene expression, chimeric fusions, between the beta-glucuronidase reporter gene (GUS) and the isolated promoter regions of the pvPDF gene (pvPDF-PRO: GUS), were constructed and introduced into Nicotiana tabacum. Analysis of transgenic pvPDF-PRO:GUS
The cumulative ozone effect on morphological parameters (visible leaf injury, plant height and leaf growth, number of bean pods, petunia flowers and stalks) was examined in this study. Well-known ozonesensitive (Bel W3) and ozone-resistant (Bel B) tobacco cultivars as well as bean cv. Nerina and
Tobacco ringspot virus (TRSV) induces circular, darkbrown local lesions on primary leaves of lima bean (Phaseolus lunatus cv Nemagreen) with a concomitant production of three basic and three acidic pathogenesisrelated (PR) proteins. The three basic proteins are: a 21 kDa protein related
Zamia furfuracea (Zamiaceae) is native of coastal Mexico. It is a popular houseplant and easy to grow outdoors in warm climates. In November 2005, a plant of Z. furfuracea, originally from Texas, was received at the Division of Plant Industry in Gainesville, FL. The plant had numerous chlorotic
A virus disease of peanut (groundnut, Arachis hypogaea L.), characterized by necrosis of the stem and terminal leaflets followed by death, caused severe crop losses in Andhra Pradesh, India during the rainy season of the year 2000. The disease was referred to as peanut stem necrosis disease (PSND).
Kudzu is an introduced legume commonly found growing as a perennial throughout the southeastern United States. This fast-growing vine was originally planted as an ornamental for forage and to prevent erosion (2), but is now considered an invasive species. During April 2011, a kudzu plant growing
Safflower, Carthamus tinctorius L. (Asteraceae), is extensively cultivated in India, China, and other parts of Asia for edible oil, dyeing agent, and its medicinal value. In 2003, safflower entry (NARI-6) in the All-India Coordinated Research Project on Oilseeds (Safflower) grown in the experimental
Two begomovirus species, Tomato yellow leaf curl Sardinia virus (TYLCSV) and Tomato yellow leaf curl virus (TYLCV), have been identified as causal agents of tomato yellow leaf curl disease (TYLCD) in Spain. TYLCSV was reported in Spain in 1992 and TYLCV in 1997 on tomato crops (3). TYLCV was also
The development of tools which ensure the desired level of transgene expression in plastids is a prerequisite for the effective utilization of these plant organelles for the deployment of bioactive proteins. High-level accumulation of target proteins is considered as a positive feature of
Antibodies were raised in rabbits against 2Fe-2S ferredoxin from N. tabacum L. The antibodies showed partial cross-reactivity in the double diffusion test with ferredoxins from Spinacia oleracea L., Petunia inflata Fries., P. axillaris Lam., Phaseolus vulgaris L., Chlamydomonas remhardii Dang. A
A structural gene encoding nitrite reductase (NiR) in bean (Phaseolus vulgaris) has been cloned and sequenced. The NiR gene is present as a single copy encoding a protein of 582 amino acids. The bean NiR protein is synthesized as a precursor with an amino-terminal transit peptide (TP) consisting of
Two transgenic tobacco lines were genetically engineered to contain chimaeric genes encoding the glutamine synthetase (GS) gamma polypeptide of Phaseolus vulgaris (French bean), expressed from the cauliflower mosaic virus 35S promoter. One (MIT-1) contained two copies of a construct including the
We used a heterologous system (transgenic Nicotiana tabacum L.) to investigate the processing, assembly and targeting of phytohemagglutinin (PHA), the lectin of the common bean, Phaseolus vulgaris L. In the bean, this glycoprotein accumulates in the protein bodies of the storage parenchyma cells in
We are examining various plant-based systems to produce enzymes for the treatment of human lysosomal storage disorders. Constitutive expression of the gene encoding the human lysosomal enzyme, alpha-L-iduronidase (IDUA; EC 3.2.1.76) in leaves of transgenic tobacco plants resulted in low-enzyme
