Tissue culture is useful method for large scale production of healthy corms and also avenues for creating variability through in vitro use of mutagens and polyploidizing agents. Induction of callus and subsequent regeneration of plants is suggested as possible means of introducing new variation. In vitro micropopagation for product formation its utility is increasing the amount of crocin, picro...

Crocins, the glucosides of crocetin, are present at high concentrations in saffron stigmas and accumulate in the vacuole. However, the biogenesis of the saffron chromoplast, the changes during the development of the stigma and the transport of crocins to the vacuole, are processes that remain poorly understood. We studied the process of chromoplast differentiation in saffron throughout stigma d...

Abstract Saffron ( Crocus sativus L., Iridaceae) is a highly valued species in the food, medicinal, and nutraceutical industries as coloring, flavoring, therapeutic agent. Its productivity flower production vary depending on different factors, including fertilizer treatment. This study was conducted to evaluate effects of inorganic (NK) combined with organic matter plant densities well influenc...

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...

Generation of volatiles by thermal treatments has been studied in saffron spice for two reasons: (a) to determine volatile profile changes during simulated aging processes and (b) to study the volatile generation pathway. During the aging process, while the amounts of C10 compounds such as safranal and HTCC increase, the amounts of C9 compounds such as isophorone and 2,6,6-trimethylcyclohexane-...

Obesity is associated with various diseases, particularly diabetes, hypertension, osteoarthritis and heart disease. Research on possibilities of herbal extracts and isolated compounds from natural products for treating obesity has an upward trend. Saffron (Crocus Sativus L. Iridaceae) is a source of plant polyphenols/carotenoids, used as important spice and food colorant in different parts of t...

Saffron (Crocus sativus L.), has been used since ancient ages in food for its flavouring, aromatic and colouring properties but also for its biomedical activity. In the past years many efforts have been made in order to demonstrate scientifically the healthy effects attributed to saffron consumption since Dioscorides’ time. More than 400 papers have been published in the last decade related to ...

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...
