Grapevine fingerprinting using microsatellite repeats
Five different microsatellite loci have been amplified through PCR (Polymerase Chain Reaction) in order to find polymorphisms useful for identification of 16 cvs and 42 clones or populations of Vitis vinifera L. No genetic variability was detected among clones and populations. Ail the cultivars have been identified, except those derived from bud mutations involving the colour of the berries, as the Pinot group (P. noir, P. blanc, P. gris), or those thought to be closely correlated or synonymous, such as 'Refosco di Faedis' and 'Refoscone'. One locus (VVS2) showed a high polymorphism with 12 alleles detected on high resolution agarose gel
Degradation versus self-assembly of block copolymer micelles
The stability of micelles self-assembled from block copolymers can be altered
by the degradation of the blocks. Slow degradation shifts the equilibrium size
distribution of block copolymer micelles and change their properties.
Quasi-equilibrium scaling theory shows that the degradation of hydrophobic
blocks in the core of micelles destabilize the micelles reducing their size,
while the degradation of hydrophilic blocks forming coronas of micelles favors
larger micelles and may, at certain conditions, induce the formation of
micelles from individual chains.Comment: Published in Langmuir http://pubs.acs.org/doi/pdf/10.1021/la204625
