RAPD and ITS-based variability revealed in Atriplex species introduced to semi-arid zones of Morocco

Genetic Variation among Fragmented Populations of <i>Atriplex halimus</i> L. Using Start Codon Targeted (SCoT) and ITS1-5.8S-ITS2 Region Markers

“…The study of genetic diversity of Atriplex halimus from diverse environment of the Mediterranean Basin showed a very high intra-populational diversity [4] [20] [21]. These authors found that two genetics groups of A. halimus can be distinguished and the genetic diversity of their collection was explained mainly by the within population component.…”

Internal transcribed spacer sequences analysis of genetic variation among and within populations of Atriplex halimus from different bioclimatic zones in Morocco

“…Evaluation of genetic diversity among and within Atriplex halimus populations plays a crucial role to minimise genetic erosion and to establish efficient strategies for genetic resources conservation in ex-situ and in-situ conditions, as well as to work out the scheme of breeding programs for biomass production and salinity tolerance (Bouda et al 2008). Different markers were used to assess the genetic diversity in Atriplex halimus at level of Mediterranean Basin (Abbad et al 2004, Elframawy et al 2016.…”

“…Owing to its tolerance to environmental stresses and its use as a fodder shrub for livestock in low rainfall areas (Le Houérou 1992), Atriplex halimus is the most planted native species of fodder trees and shrubs in West Asia and Nord Africa (Le Houérou 2000). Atriplex halimus was used, also, as a promising species for the reclamation of degraded lands where excessive salinity and low moisture level are the main factors limiting plants growth, but where there is also a need for animal forages (Bouda et al 2008). In Morocco, A. halimus L. is widely distributed as a wild species, particularly in habitats that combine relatively high soil salinity with aridity.…”

“…This is unfortunately due to their modest economic value generally attributed to shrubby species, which are not yet seriously considered as cultivated species (Stringi et al 1994). Nevertheless, in the last two decades, with climate changes and the resulting threats to the survival plant populations, substantial works have been devoted to study the genetic diversity of Atriplex halimus (Bouda et al 2008, El Ferchichi et al 2006, Elframawy et al 2016, Haddioui and Baaziz 2001, Ortíz-Dorda et al 2005, Walker et al 2005, Zhu et al 2001. It seems that there is a large genetic variability in Atriplex halimus populations of different Mediterranean origins and such heterogeneity could be exploited to develop adequate populations with a combination of good traits such as high adaptability to limiting factors in arid and semi-arid Mediterranean environments.…”

Preliminary molecular analysis of the genetic diversity of some Atriplex species present in the Northeast of Algerian

“…Little study is carried on the assessment of their genetic diversity where its master is necessary for the good management and the valorization of this plant genetic resource (Abbad et al, 2004). For example; the works of Bouda et al (2008) and Haddioui and Baazizes (2001) carried on the molecular analysis of the genetic diversity of some Atriplex species existing in Morocco and in USA. And the works of Ortiz-Dorda et al (2005) that had the same aspect, but these researches are realized on existing populations in all countries of the Mediterranean basin.…”
