Novel Microsatellite Markers Reveal Evidence of Sexual Reproduction in Dematophora necatrix Populations From South African Avocado Orchards

open access: yesPlant Pathology, Volume 75, Issue 1, January/February 2026.
The study reveals the presence of sexual reproduction in Dematophora necatrix populations from South African avocado orchards through the development of novel microsatellite markers. This finding enhances the understanding of genetic diversity and population structure within these populations, emphasising the significance of alleles and genotype ...

Fine Characterization of the Contact Zones of Mazzaella laminarioides in the Southeastern Pacific Using Mitochondrial and Nuclear Markers

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates the genetic structure of Mazzaella laminarioides, an ecologically and economically important species from the rocky coast of Chile. Using more accurate sampling and a set of microsatellite, nuclear, and mitochondrial markers, we were able to identify with high resolution the contact zones between the previously described ...

Life history of Monocystis parasites and genetic diversity of their hosts, the invasive Amynthas earthworms [PDF]

open access: yes, 2016
Monocystis is a parasites in the phylum Apicomplexa that infects nearly 100% of earthworms; however, the parasites have low survivorship, low production of transmissible gametocysts, and seemingly lack schizogony.

Isolation by distance in a population of a small land snail Trochoidea geyeri : evidence from direct and indirect methods [PDF]

open access: yes, 2006
Population structure was estimated in a continuous population of a small land snail (Trochoidea geyeri). Mark-recapture experiments and randomly amplified polymorphic DNA analyses indicate that the population structure can be described by the isolation ...
