A mitochondrial DNA (mtDNA) region termed the S-pcf locus has previously been correlated with cytoplasmic male sterility (CMS) in Petunia. In order to understand the relationship of the S-pcf locus to homologous sequences found elsewhere in mtDNAs of both CMS and fertile lines, the structure of the mitochondrial genome of CMS Petunia line 3688 was determined by cosmid walking. The S-pcf locus, ...

MADS-domain proteins are important transcription factors involved in many biological processes of plants. Interactions between MADS-domain proteins are essential for their functions. In tomato (Solanum lycopersicum), the number of MIKC(c)-type MADS-domain proteins identified has totalled 36, but a large-scale interaction assay is lacking. In this study, 22 tomato MADS-domain proteins were selec...

In petunia flowers, the loci an1, an2, and an11 control the pigmentation of the flower by stimulating the transcription of anthocyanin biosynthetic genes. The an1 and an2 locus were recently cloned and encode a basic helix-loop-helix (bHLH) and MYB-domain transcriptional activator, respectively. Here, we report the isolation of the an11 locus by transposon tagging. RNA gel blot experiments show...

Recently, CRISPR/Cas9 technology has emerged as a powerful approach for targeted genome modification in eukaryotic organisms from yeast to human cell lines. Its successful application in several plant species promises enormous potential for basic and applied plant research. However, extensive studies are still needed to assess this system in other important plant species, to broaden its fields ...

Flavonol aglycones are required for pollen germination in petunia (Petunia hybrida L.). Mutant plants lacking chalcone synthase (CHS), which catalyzes the first committed step in flavonoid synthesis, do not accumulate flavonols and are self-sterile. The mutant pollen can be induced to germinate by supplementing it with kaempferol, a flavonol aglycone, either at the time of pollination or by add...

The regulation of the arbuscular mycorrhizal (AM) symbiosis is largely under the control of a genetic programme of the plant host. This programme includes a common symbiosis signalling pathway that is shared with the root nodule symbiosis. Whereas this common pathway has been investigated in detail, little is known about the mycorrhiza-specific regulatory steps upstream and downstream of the co...

Glyphosate showed a remarkable effect inducing the change of flower symmetry from the actinomorphic to the zygomorphic type in Petunia hybrida. Glyphosate [N-(phosphonomethyl)glycine] reduced the anthocyanin content and showed a weak inhibitory effect against phenylalanine ammonia-lyase (PAL) activity. L-2-Aminooxy-3-phenylpropionic acid (APA), an inhibitor of PAL activity, reduced the anthocya...

The effect of ethylene on the growth rate of pollen tubes in styles of Petunia hybrida was examined. Apart from its strong inhibition of pollination-induced ethylene synthesis, aminoethoxyvinylglycine, placed on the stigma, did not impede tube growth. The inhibitors of the action of ethylene, silver thiosulfate and 2,5-norbornadiene, were similarly ineffective. Application of the ethylene precu...

A novel ATP synthase subunit 9 gene (atp9) was identified in the mitochondrial genome of a Petunia somatic hybrid line (13-133) which was produced from a fusion between Petunia lines 3688 and 3704. The novel gene was generated by intergenomic recombination between atp9 genes from the two parental plant lines. The entire atp9 coding region is represented on the recombinant gene. Comparison of ge...

An anti-petunia glycine-rich protein 1 (ptGRP1) antibody was used for biotin-streptavidin-alkaline phosphatase localization of this protein. In petunia stem and leaves grown under different light conditions, these studies revealed a complex pattern of cell localization for this protein. Levels of ptGRPl were shown to decrease with developmental age of the tissue, appearing to correlate directly...
