Epigenetic Variability Among Saffron Crocus ( L.) Accessions Characterized by Different Phenotypes.

This work represents the first epigenomic study carried out on saffron crocus. Five accessions of saffron, showing differences in tepal pigmentation, yield of saffron and flowering time, were analyzed at the epigenetic level by applying a methylation-sensitive restriction enzyme-sequencing (MRE-seq) approach. Five accession-specific hypomethylomes plus a reference hypomethylome, generated by combining the sequence data from the single accessions, were obtained.

Epigenetic Barcodes for Detection of Adulterated Plants and Plant-Derived Products.

In this chapter, we report a possible alternative use of epigenetics by applying methylation-sensitive amplified fragment length polymorphisms (MS-AFLP) to saffron traceability. Saffron is the most expensive plant-derived product in the world and one of the most frequently adulterated. One of the most frequent adulteration is by adding to saffron stigmas different parts of the saffron flower itself to increase volumes.

Epigenetic stability in Saffron (Crocus sativus L.) accessions during four consecutive years of cultivation and vegetative propagation under open field conditions.

Saffron (Crocus sativus L.) is a sterile species that is vegetatively propagated in the field, year by year, via the production of new corms. While Saffron's genetic variability is extremely low, phenotypic variation is frequently observed in the field and epigenetics could be a possible origin of these alternative phenotypes.

Phenolic Profiling for Traceability of ×.

Vanilla is a flavoring recovered from the cured beans of the orchid genus . × is traditionally cultivated on the islands of French Polynesia, where vanilla vines were first introduced during the nineteenth century and, since the 1960s, have been introduced to other Pacific countries such as Papua New Guinea (PNG), cultivated and sold as "Tahitian vanilla," although both sensory properties and aspect are different. From an economic point of view, it is important to ensure .

Genetic and Epigenetic Approaches for the Possible Detection of Adulteration and Auto-Adulteration in Saffron (Crocus sativus L.) Spice.

Saffron (Crocus sativus L.) is very expensive and, because of this, often subject to adulteration. Modern genetic fingerprinting techniques are an alternative low cost technology to the existing chemical techniques, which are used to control the purity of food products.

Direct amplification of new cellulase genes from woodland soil purified DNA.

Eight genes encoding cellulolytic enzymes were obtained by direct PCR amplification of genomic DNA recovered from woodland soil samples. The direct amplifications were carried out by using primers designed from available online cellulase nucleotide sequences. The isolated genes were all different from each other and homologous to endo-β-1,4-glucanases of Bacillus subtilis.
