Arabidopsis flowers have four petals. Other floral organs are not represented on the diagram. KLU expression in petals is shown in red. Wild-type tissue is shown in yellow whereas klu mutant tissue is shown in blue. Wild-type flowers are larger than klu mutant flowers. Flowers that contain wild-type and mutant tissue (chimeric flowers) are of intermediate size between wild-type and mutant flowe...

Leafless cut Superstar roses (Rosa hyb.) were kept in a 1% sucrose solution. During the first few days of treatment, the abscisic acid content and the water deficit in the petals was higher in treated flowers than in controls kept in water. Later and up to the termination of the flower's life, ABA content and water deficit values were lower in petals of sucrose-treated flowers than in controls....

An efficient catalytic effect of petals and flowers like CuO nanostructures (NSs) on the degradation of two organic dyes, methylene blue (MB) and rhodamine B (RB) were investigated. The highest degradation of 95% in CuO petals and 72 % in flowers for MB is observed in 24 h. For RB, the degradation was 85 % and 80 % in petals and flowers, respectively for 5 h. It was observed that CuO petals app...

We isolated and characterized two flower-specific genes from petunia. The protein products of these genes, designated floral binding protein 1 (FBP1) and 2 (FBP2), are putative transcription factors with the MADS box DNA binding domain. RNA gel blot analysis showed that the fbp1 gene is exclusively expressed in petals and stamen of petunia flowers. In contrast, the FBP1 protein was only detecta...

Flavonoid biosynthesis has received much attention concerning the structural genes and expression of the associated transcription factors (TFs). In the present study, we examined the gene expression patterns for petals of three colors using a statistical method. Factor analysis was successfully used to examine the expression patterns most present during regulation. The first expression patterns...

Flowering plants bear beautiful flowers to attract pollinators. Petals are the most variable organs in flowering plants, with their color, fragrance, and shape. In Arabidopsis (Arabidopsis thaliana), petal primordia arise at a similar time to stamen primordia and elongate at later stages through the narrow space between anthers and sepals. Although many of the genes involved in regulating petal...

Mot, Y., Reid, M.S. and Kofranek, A.M., 1980. Role of the ovary in carnation senescence. Scientia Hortic., 13: 377--383. Ovary growth in carnation flowers was inhibited by pre-treatments with silver thiosulfate which retarded petal senescence. Although the start of ovary growth preceded visible wilting of untreated flowers, the ovary does not appear to control carnation senescence. Its removal ...

Variegated plants are highly valuable in the floricultural market, yet the genetic mechanism underlying this attractive phenomenon has not been completely elucidated. In this study, we identified and measured different compounds in pink and white flower petals of peach (Prunus persica) by high-performance liquid chromatography and liquid chromatography/mass spectrometry analyses. No cyanidin-ba...
