In January 2012, spreading type petunia cv. Wave Pink plants showing an abnormal growth habit of sprouting unusual multiple plantlets from the lateral buds were collected from a greenhouse in Gwacheon, Gyeonggi Province, Korea. The presence of phytoplasma was investigated using PCR with the primer pairs P1/P6, and R16F1/R1 for nested-PCR. In the nested PCR, 1,096 bp PCR products were obtained, ...

A procedure is developed for the isolation of intact chloroplast DNA (ctDNA) from Petunia hybrida. The molecular weight, calculated from contour length measurements, is 96.0 +/- 4.5 x 10(6) daltons. This value is in good agreement with the value of 101.2 x 10(6) daltons that was estimated from the electrophoretic mobilities of restriction endonuclease fragments of ctDNA. Analysis of petunia ctD...

A procedure to identify dihydroflavonol (glucosides), cinnamic acids and anthocyanins in flowers of Petunia hybrida is presented. Nearly all known intermediates and anthocyanins ocurring in Petunia are separated on one column using different elution systems. Hydrolysis of extracts before HPLC and thin layer chromatography is in some cases necessary to make positive identification of flavonoids....

Research into molecular mechanisms of self-incompatibility (SI) in plants can be observed representatives various families, including Solanaceae. Earlier studies the S-RNase-based SI petunia (Petunia hybrida E. Vilm.) demonstrate that programmed cell death (PCD) is an factor. These suggest phytohormon cytokinin (CK) putative activator caspase-like proteases (CLPs). In this work, data confirming...

a pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. the study of zinc sulphate (znso4) application (20 and 40 ppm) and salicylic acid (sa) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering petunia hybrid. for each plant was used 100 cc of solution at ...

Abstract The Neotropical region holds high plant species richness, and these originated under the influence of climate changes, tectonic processes ecological factors. Several genera Solanaceae have appeared diversified quickly in area, producing a number lineages. Petunia is endemic to grasslands southern South America constitutes one young groups. From this perspective, I aim identify driving ...

In many flowering plants, such as petunia (Petunia x hybrida), ethylene produced in floral organs after pollination elicits a series of physiological and biochemical events, ultimately leading to senescence of petals and successful fertilization. Here, we demonstrate, using transgenic ethylene insensitive (44568) and Mitchell Diploid petunias, that multiple components of emission of volatile or...
