Apricot latent virus – Review

The Major Sources of Genetic Differentiation Among Apricot Latent Virus (ApLV) Isolates

Background and Aims: Apricot latent virus (ApLV) is a species within Foveavirus genus (Betaflexiviridae family, Tymovirales order). Phylogenetic analyses using different ORFs nucleotide sequences divided most ApLV isolates into two clusters. However, there is little data about the sources of genetic differentiation among ApLV isolates. Materials and Methods: Partial coat protein (CP) sequences...

Purification and Characterization of Latent Polyphenol Oxidase from Apricot (Prunus armeniaca L.)

Polyphenol oxidase from apricot (Prunus armeniaca) (PaPPO) was purified in its latent form (L-PaPPO), and the molecular weight was determined to be 63 kDa by SDS-PAGE. L-PaPPO was activated in the presence of substrate at low pH. The activity was enhanced by CuSO4 and low concentrations (≤ 2 mM) of SDS. PaPPO has its pH and temperature optimum at pH 4.5 and 45 °C for catechol as substrate. It s...

Are Apricot Kernels Toxic?

If future research shows that Laetrile has value, we can expect the consumption of apricot kernels to increase. Critics of Laetrile have asserted that apricot kernels are highly toxic. Case histories confirm that negative reactions to eating apricot kernels can take place, but such reports are rare, and we have only suggestive evidence concerning what doses cause adverse effects.
