The DNA of this type of mobile elements is evolving faster than the DNA of other markers in this clonal lineage, and two geographical distant groups have evolved in agreement with polymorphisms based on IRAP markers anchored to at least, two different Copia-like retrotransposon sequences.

It is concluded that, in most cases, microsatellites are more efficient than isozymic markers to identify the sexual origin of citrus seedlings, given their higher level of polymorphism and the scarce number of polymorphic isozymes in some populations.

This work provided a general understanding of the reticulate process of hybridization and introgression acting on Mesocarabus and generated the hypothesis of seven Mesoccarabus species, including two putative hybrid lineages.

Differences in the amount of virions are not explained through the selection of CTV genotypes by the host, but through differences among citradias in CTV replication and/or movement.
Presence of nuclear copies of mitochondrial origin (NUMTs) in two related species of stingless bee genus Melipona (Hymenoptera: Meliponini)
- C. Ruiz, W. May-Itzá, J. J. G. Quezada-Euán, P. Rúa

This is one of the first studies reporting the presence of numts in Meliponini species, and supports previous studies suggesting frequent transfer of mtDNA to the nuclear genome in Hymenoptera.
Barcoding stingless bees: genetic diversity of the economically important genus Scaptotrigona in Mesoamerica

Results confirm the hypothesis that the DNA barcoding technique may at least differentiate stingless bee taxa accepted by current taxonomy and confirm the existence of cryptic species within S. mexicana, one of the stingless bees exploited for honey production in Mesoamerica.
Molecular Markers for the Genetic Analysis of Apomixis
- M. Asins, M. R. García, C. Ruiz, E. Carbonell
- Biology
- 2002
Most flowering plants reproduce sexually through seeds having an embryo, which is formed without reduction of the chromosome number nor fertilisation, by a process called apomixis (Nogler, 1984).
UTILIZACIÓN DE EXTRACTOS DE PLANTAS PARA EL CONTROL DE GORGOJO PARDO ACANTHOSCELIDES OBTECTUS (SAY) EN FRIJOL ALMACENADO USE OF EXTRACTS OF PLANTS FOR THE CONTROL OF BROWN WEEVIL ACANTHOSCELIDES…

Results indicate that the extracts used were effective against A. obtectus, with mortality rates of 30 and 50 percent of emergency, and the percentages of damaged grain were higher in the control compared with treatments applied (< 50%).
Dormancy breaking and germination of Adenocarpus desertorum, Astragalus gines-lopezii and Hippocrepis grosii (Fabaceae) seeds, three threatened endemic Spanish species

- 30 April 2016
The most effective method for promoting germination of Adenocarpus desertorum and Astragalus gines-lopezii (two populations) was mechanical scarification with pliers, and the highest germination percentages of H. grosii were reached by seeds mechanically scarified and also by seeds stored in an ultra-low freezer for 24 hours.
