“…In the last few decades, the genetic diversity of nut trees in Iran has been extensively studied using various molecular markers systems. Patterns of population structures and genetic diversity of almond have been studied by several molecular marker systems, including isozymes [6], randomly amplified polymorphic DNA (RAPDs) [7], amplified fragment length polymorphism (AFLPs) [8], simple sequence repeat (SSRs) and EST-SSR [9][10][11]. The use of molecular markers in pistachio breeding and genetic conservation, like in many fruit trees, began with isozymes, then RFLPs, RAPDs, AFLPs, inter simple sequence repeats (ISSRs), sequence-related amplified polymorphism (SRAPs), SSRs, non-coding chloroplast DNA markers and finally single nucleotide polymorphism (SNPs) [2].…”

As one of the main origin centers of nut trees, Iran is the fourth leading nut crops producer in the world (6% of total nut production). Due to the high genetic diversity, development of new varieties and rootstocks with desirable characteristics have been highly considered by fruit breeders in Iran. In this regard, molecular breeders concentrate on filling the gaps in the conventional breeding with the aim of accelerating breeding programs. Recent advancements in molecular breeding such as next-generation sequencing (NGS) techniques, high-throughput genotyping platforms and genomics-based approaches including genome wide association studies (GWAS), and genomic selection (GS) have opened up new avenues to enhance the efficiency of nut trees breeding. Over the past decades, Iranian nut crops breeders have successfully used advanced molecular and genomic tools such as molecular markers, genetic transformations and high-throughput genotyping to explore the genetic basis of the desired traits and eventually to develop new varieties and rootstocks. Due to a broad international cooperation, a clear perspective is envisaged for the nut breeding programs in Iran, especially based on new biotechnology techniques. The propagation of nut trees in Iran have also been dramatically improved. Different types of grafting and tissue culture (micropropagation or somatic embryogenesis) techniques for propagation of nut crops have been studied intensively in the last 30 years in Iran and the successful techniques have been commercialized. Several certified nurseries are producing grafted and micropropagation plants of walnut, pistachio and other nut crops commercially. A part of the grafted and micropropagaited plants of nut crops in Iran is being exported to the other countries. Establishing modern orchards of nut crops using new cultivars and rootsocks is presently being advised by professional consultants.

“…Ecological niches and species distribution models are useful tools for proper planning the use of natural resources. The set of geographic and environmental information, together with information on genetic variability and genetic structure, are valuable for the establishment of new germplasm collections and conservation sites (Cavanzon‐Medrano, M'rabet, Chablé‐Iuit, Pozo, & Hénaut, 2018; Condón, Jaurena, Reyno, Otaño, & Lattanzi, 2017; Zeinalabedini et al., 2019). Studies of this kind have been carried out in populations of some Stylosanthes species (Barros et al., 2005; Sawkins et al., 2001), but so far none of them describes the use of spatial models based on the genetic grouping system and geographic information from Argentinian populations, nor from S. hippocampoides populations.…”

Patterns of genetic diversity and potential ecological niches of Stylosanthes species from northeastern Argentina

The Stylosanthes genus is native to Central and South America and contains several of the most important tropical legumes used for forage. The southernmost natural distribution of the genus includes the northeast of Argentina, a subtropical region where several phytogeographic provinces and ecoregions converge, giving rise to particular environmental conditions. Here, we used inter-simple sequence repeat markers to evaluate the genetic diversity and genetic structure of four and eight natural populations from northeast of Argentina of Stylosanthes guianensis (Aubl.) Sw. and S.hippocampoides Mohlenbr., respectively. We also modeled the potential ecological niches to obtain environmental information regarding new collection areas and future crop areas. High genetic diversity and specific bands were found for both species. The summary statistics were relatively higher for S. guianensis than for S. hippocampoides. In both species, more genetic diversity was present among populations than within them, and correlation between genetic and geographic distances was observed. Populations were grouped according to their respective species, and their geographical source. The results suggest that collecting a few individuals from a large number of different sites would be an appropriate method for conserving the diversity of these species, with emphasis on those areas with the highest levels of genetic diversity. The modeling of ecological niches suggested mean temperature of the coldest quarter as the most important bioclimatic variable influencing S. guianensis distribution, and temperature seasonality as the variable influencing S. hippocampoides distribution, and showed new potential areas for future collections and as potential crop areas of the species.Abbreviations: AUC, area under the curve; ISSR, inter-simple sequence repeat; NEA, the northeastern region of Argentina; PCR, polymerase chain reaction; SSR, simple sequence repeat; TAE, tris-sodium acetate-ethylenediaminetetraacetic acid.
