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

The lipid-rich, sticky exudate covering the stigma of solanaceous species such as tobacco (Nicotiana tabacum) and petunia (Petunia hybrida) contains several proteins, of which only some have been characterized to date. Proteome analysis of the stigmatic exudate in both species revealed the presence

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

The expression of a 25 kDa protein, encoded by the fused mitochondrial pcf gene, is associated with cytoplasmic male sterility (CMS) in petunia. To investigate the role of the 25 kDa protein in CMS we have transformed petunia and tobacco plants with constructs expressing a portion of the urfS

A 1.6 kb repetitive DNA sequence (RPS) from Petunia hybrida was identified that destabilizes expression of a GUS marker transgene. Following polyethylene glycol (PEG)-mediated tobacco and petunia protoplast transformations, GUS expression patterns analysed on callus and plant levels were clearly

During 2003 and 2004, unusual viral symptoms were observed on Surfinia trailing petunias in protected cultivations of Southern France. Symptoms consisted in yellow mosaic and distortion of the leaves accompanied by vein necrosis in some samples. The flowers were deformed and showed light colour

PRK1, a receptor-like kinase that is expressed in pollen, pollen tubes, and ovaries, has been shown to play important roles in pollen development and embryo sac development in Petunia inflata. We have used the kinase domain of PRK1 as a bait in the yeast two-hybrid system to identify

Extremely asymmetric nuclear hybrids have been obtained via protoplast fusion in an intergeneric combination. Irradiated (cobalt(60),100 krad) kanamycinresistant Petunia hybrida mesophyll protoplasts were chemically fused with wild-type mesophyll protoplasts of Nicotiana plumbaginifolia. Eighty-six

Transposition of the Anthirrinum majus Tam3 element and the Zea mays Ac element has been monitored in petunia and tobacco plants. Plant vectors were constructed with the transposable elements cloned into the leader sequence of a marker gene. Agrobacterium tumefaciens-mediated leaf disc

Late blight, caused by the pathogen Phytophthora infestans, is a devastating disease of potato and tomato, but can also damage other solanaceous hosts. To gain a better understanding of the interaction between P. infestans and these other hosts, the susceptibility of species in three solanaceous

Molecular and genetic analyses have shown that the Arabidopsis thaliana gene SUPERMAN (SUP) has at least two functions in Arabidopsis flower development. SUP is necessary to control the correct distribution of cells with either a stamen or carpel fate, and is essential for proper outgrowth of the

Due to the non-degradable nature of heavy metals (HMs), the industrial effluent, whether treated or untreated, carrying HMs, eventually end up into the water bodies, soil, and sediments. Numerous countermeasures were applied, but the use of ornamental plants for the stress mitigation associated with

The large subunit of Fraction 1 protein from Lycopersicon esculentum, Nicotiana tabacum and Petunia hybrida has been examined by isoelectric focusing of the S-carboxymethylated polypeptides, and by double immunodiffusion with antiserum raised against Fraction 1 protein. The immunological results

The mitochondrial genomes of cybrids of Nicotiana tabacum containing chloroplasts of Petunia hybrida were characterized by restriction endonuclease digestion and agarose gel electrophoresis. Cybrids that displayed normal growth and development contained mitochondrial DNA indistinguishable from N.

Transgenes in genetically modified plants are often not reliably expressed during development or in subsequent generations. Transcriptional gene silencing (TGS) as well as post-transcriptional gene silencing (PTGS) have been shown to occur in transgenic plants depending on integration pattern, copy
