Genotyping of fig (Ficus carica L) via RAPD markers

The genetic diversity among 15 fig accessions (Ficus carica L), belonging to 9 renowned cultivars of the Calabrian fig collection, and 24 unidentified genotypes of figs also located in the Calabrian region of Southern Italy, was investigated by random amplified polymorphic DNA (RAPD) analysis. The genetic similarity values were calculated for the 39 samples, and a dendrogram was elaborated by cluster analysis according to the UPGMA algorithm. The generated DNA fragments grouped the samples into two main clusters of RAPD profiles. Most of the 24 unknown samples, coming from the Luzzi area, formed a unique cluster with high degree of genetic similarity. This indicates that it is possible to distinguish, at DNA level, the fig trees with an already well‐known potential to produce figs suitable for the drying process and possibly to specify cultivars with suitable features for industrial transformation.

Cloning and characterization of β-agarase AgaYT from Flammeovirga yaeyamensis strain YT

A bacterium with potent agar-degrading capability was isolated from the surface of a red algae, Gracilaria tenuistipitata. Based on phenotypic characteristics, 16S rDNA gene sequence and a phylogenetic analysis, this bacterium was identified and named as Flammeovirga yaeyamensis strain YT. PCR using homology-based degenerate primers was employed to clone any agarase gene belonging to GH16 family encoded in F. yaeyamensis strain YT. The resolved 1512 nucleotides revealed that the cloned gene, namely AgaYT, encodes a protein of 503 amino acids comprising a signal peptide, a glycosyl hydrolase catalytic module and a C-terminal domain with an unknown function. The recombinant protein r-AgaYT is an endo-type β-agarase hydrolyzing agarose to yield neoagarobiose and neoagarotetraose as the main hydrolytic products. The specific activity of r-AgaYT was determined about 178.6 U mg^{− 1} at 40°C and pH 8.0.
