The Association of Severe Epidemics of Cucumber Mosaic in Commercial Fields of Pepper and Tobacco in North Florida with Inoculum in Commelina benghalensis and C. communis.

Logi sisse
Since 1995, severe epidemics of cucumber mosaic virus (CMV) have occurred in select fields of tobacco (Nicotiana tabacum) and pepper (Capsicum annuum) in three counties in northern Florida. Yield losses greater than 50% have occurred in both crops. Baker and Zettler (1) identified the presence of
A novel protein elicitor (PaNie) from Pythium aphanidermatum induces multiple defense responses in carrot, Arabidopsis, and tobacco.

Logi sisse
A novel protein elicitor (PaNie(234)) from Pythium aphanidermatum (Edson) Fitzp. was purified, microsequenced, and the corresponding cDNA was cloned. The deduced amino acid sequence contains a putative eukaryotic secretion signal with a proteinase cleavage site. The heterologously expressed elicitor
Ozone is not mutagenic in the Tradescantia and tobacco mutagenicity assays.

Ozone fumigation of a double heterozygous chlorophyll mutant Nicotiana tabacum var. xanthi n.c. with concentrations up to 300 nl/l and of a heterozygous Tradescantia clone 4430 with concentrations up to 800 nl/l did not increase the frequency of somatic mutations above the spontaneous levels.

Calcium-dependent phospholipid-binding proteins in plants : Their characterisation and potential for regulating cell growth.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
There is evidence that Ca(2+) can regulate vesicle-mediated secretion in plant cells, but the mechanism for this is not known. One possibility is that Ca(2+) -dependent phospholipid-binding proteins (annexins) couple the Ca(2+) stimulus to the exocytotic response. Using a protocol developed for the
Transitory increase in chromosomal DNA (Fleulgen) during floral differentiation in Rhoeo discolor.

Scanning cytophotometric measurements on 3200 telophase and 1700 interphase nuclei (Feulgen-stained) in vegetative and reproductive buds of Rhoeo discolor revealed a transitory increase in staining intensity in more than half of the cells in early differentiating floral buds. The differences between
Cold-specific and light-stimulated expression of a wheat (Triticum aestivum L.) Cor gene Wcor15 encoding a chloroplast-targeted protein.

Wcor15, a member of the wheat cold-responsive (Cor) gene family, has been isolated and characterized. The deduced polypeptide WCOR15 (MW=14.7 kDa) showed high homology to the previously identified wheat and barley COR proteins. Southern blot analysis using diploid, tetraploid and hexaploid wheat and

The extension of pollutant accumulation in plant leaves associated with its genotoxicity is a common approach to predict the quality of outdoor environments. However, this approach has not been used to evaluate the environmental quality of outdoor smoking areas. This study aims to evaluate the

Logi sisse
The activity of the "conditioning factor" from the cultures of plant cells of various taxa was assayed in biotests with the tobacco and wheat cell cultures. The conditioned media of crops did not activate the growth of a diluted (400-fold) culture of tobacco cells. Conditioned media from the

The distribution of structural rearrangements of the chloroplast genome found in grass cpDNA in comparison to that of tobacco was systematically checked in the cpDNAs of representative monocots. The physical map of lily cpDNA, which shares a key position in the diversity of monocotyledonous plants,

The amphiphilic dye FM4-64 is used to investigate endocytosis and vesicle trafficking in living eukaryotic cells. The standing hypothesis is that it is inserted into the outer leaflet of the plasma membrane and, from there, is passed on to intracellular membrane compartments by endocytosis. We

EuroBionet, the 'European Network for the Assessment of Air Quality by the Use of Bioindicator Plants', is an EU-funded cooperative project currently consisting of public authorities and scientific institutes from 12 cities in 8 countries. In 2000, the bioindicator plants tobacco (Nicotiana tabacum
21-kDa polypeptide, a low-molecular-weight cyclophilin, is released from pollen of higher plants into the extracellular medium in vitro.

Calcium ions play a key role in the elongation and orientation of pollen tubes. We found that significant amounts of 21-kDa polypeptide were specifically released into the extracellular medium when pollen grains of lily, Lilium longiflorum Thunb., were incubated in the presence of EGTA or at low
