“…Results from RAPDs analysis mostly confirm those obtained from flavonoid studies (Solbrig et al 1977) and electrophoresis of seed proteins (Burghardt and Palacios 1997), which divide Prosopis into identifiable sections and species. Morphological analysis has also generally, but not always, agreed with these findings (Pasiecznik et al 2001;Harris et al 2003) and most recently, ploidy determination has helped to distinguish P. juliflora from other Prosopis species. However, the results obtained from RAPDs analysis need to be treated with caution.…”

There has been much taxonomic confusion over the identification of Prosopis species, especially where introduced. Prosopis juliflora is the most widespread species in the arid and semi-arid tropics, although it has been confused with other species, particularly the closely related Prosopis pallida. In this study, RAPDs markers were used for the first time to distinguish between these species. Eighteen primers were used in amplification reactions, which yielded an average of 120 bands per accession. A dendrogram showing genetic similarities among accessions was constructed using UP-GMA cluster analysis and the Nei and Li similarity coefficient. The genetic similarity observed between P. juliflora and P. pallida is similar to the value in sympatric Prosopis species in North America, and reconsideration of the series rank in section Algarobia is suggested. Species-specific markers confirmed that material in Burkina Faso is P. juliflora, but suggested that material collected in Brazil, Cape Verde and Senegal is P. pallida, whereas this has previously been identified as P. juliflora.

“…Interestingly, the herbivorous teiid C. murinus, on Bonaire, generally avoids leaves of Prosopis juliflora (Dearing and Schall, 1992), possibly because of their high saponin content (Dearing and Schall, 1992). Prosopis juliflora is closely related to P. pallida (Harris et al, 2003;Burghardt and Espert, 2007), but little is known about the presence and abundance of saponin and other secondary metabolites in P. pallida. Prosopis pallida is a nitrogen fixing tree species (Ramírez-Orduñ a et al, 2005), and its leaves are rich in nitrogen (concentration of 3.24 6 0.32%, compared with only 1.50 6 0.30% for the sympatric Capparis scabrida; Havik, 2010).…”

“…Trenchard et al (2008) analizaron mediante citometría de flujo material proveniente de América e India y hallaron especies diploides (2n = 2x = 28) y tetraploides (2n = 4x = 56). Los autores concluyen, en concordancia a lo enunciado por Harris et al (2003), que P. juliflora es la única especie tetraploide y que los ejemplares triploides (2n = 3x = 42) descubiertos son casos excepcionales resultantes de la hibridación de P. juliflora (tetraploide) con un diploide, posiblemente P. pallida o P. chilensis, que ocurren en las áreas de recolección del material analizado. Roig (1993) propone que el proceso evolutivo del género se evidencia en las bioformas (espinas, hojas y frutos) y que la especiación se habría producido en las zonas periféricas al conquistar nuevos nichos.…”

ResumenProsopis es un género dentro del clado Mimosoid caracterizado por las disyunciones que presentan sus actuales áreas de distribución y las dificultades para esclarecer su filogenia. Este trabajo presenta un análisis bibliográfico actualizado sobre las características evolutivas, citogenéticas, genéticas e hibridaciones del género. Los datos disponibles sugieren que divergió tempranamente en varios linajes principales, aunque dentro de algunos de ellos han ocurrido episodios recientes de especiación parcial. La forma en que se distribuye la variabilidad genética dentro y entre poblaciones depende, entre otros factores, del sistema reproductivo y la estrategia adaptativa. La estructura de las poblaciones, a su vez, establece restricciones a los procesos evolutivos tendientes a la adaptación creciente al ambiente y/o la diferenciación específica. . Es un género esencialmente diploide (2n = 28) pero se ha informado poliploidía y frecuentes procesos de hibridación e introgresión interespecífica. La alta similitud genética y cromosómica entre las distintas especies del género permite la obtención de híbridos viables, reforzando la idea de que algunas especies del género están evolutivamente activas, y pone de manifiesto las dificultades que esto ocasiona en el tratamiento taxonómico y la filogenia del grupo. Palabras clave: algarrobo, botánica, mezquite, sistemática, taxonomía. AbstractProsopis is a primitive genus in the Mimosoid's clade characterized by disjunctions in its distribution areas and the difficulty in establishing its phylogeny. This paper presents an updated literature review on the evolutionary, cytogenetic, genetic and hybridization characteristics of the genus. The available data suggest that it diverged early in several major lineages, although in some of them recent episodes of partial speciation have occurred. Genetic diversity within and between populations depends on the reproductive system and adaptative strategies, among other factors. Populations' structure also sets restrictions to evolutive processes leading to the increasing adaptation to the environment and/or specific differentiation. It is an essentially diploid genus (2n = 28) never the less polyploidy and frequent processes of interspecific hybridization and introgression have been informed. High genetic and chromosomal similarity between species of the genus allows the generation of viable hybrids, reinforcing the idea that some species are evolutionarily active and highlights the difficulties this causes in the taxonomic treatment and the phylogeny of the group. Key words: carob tree, botany, mesquite, systematic, taxonomy. (Tapia Pastrana et al. 1999). Estos fenómenos sustentarían la idea de que Prosopis es un antiguo género que divergió tempranamente en varios linajes principales, pero que dentro de algunos de ellos han ocurrido episodios recientes de especiación parcial (Burkart & Simpson 1977).
