Analysis of Juniperus phoenicea from throughout its range in the Mediterranean using DNA sequence data from nrDNA and petN-psbM: the case for the recognition of J. turbinata Guss [PDF]

open access: yes, 2013
DNA sequences were analyzed from 19 populations of J. phoenicea from throughout its range. The sequence data (nrDNA, petN-psbM) revealed that J. phoenicea is clearly divided into two taxa. These taxa have been recognized as var.

Relationships among different geographical groups, agro-morphology, fatty acid composition and RAPD marker diversity in Safflower ( Carthamus tinctorius ) [PDF]

open access: yes, 2018
Patterns of geographical diversity, and the relationship between agro-morphological traits and fatty acid composition were assessed for 193 safflower (Carthamus tinctorius) accessions representing forty countries. Accessions were assigned to eight groups

Dna fingerprinting - review paper [PDF]

open access: yes, 2006
Before the Polymerase Chain Reaction (PCR) was established, DNA fingerprinting technology has relied for years on Restriction Fragment Length Polymorphism (RFLP) and Variable Number of Tandom Repeats (VNTR) analysis, a very efficient technique but ...

Was Dan Janzen (1977) right about aphid clones being a "super-organism", i.e. a single "evolutionary individual"? : new insights from the use of molecular marker systems [PDF]

open access: yes, 2008
Dan Janzen proposed in a paper in 1977 (loc. cit.), that a clone of aphids and for that matter dandelions consists, respectively, of one large ‘super-organism’.
