The present work describes the changes in the activities of key antioxidant enzymes and the levels of some metabolites in relation to salt tolerance in eight wild almond species. All the species were exposed to four levels of NaCl (control, 40, 80 and 120 mM). Plant fresh biomass, α-, γ- and δ-tocopherol, total soluble proteins, malondialdehyde (MDAeq), H2O2, total phenolics, and the activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) were analyzed in leaves of salt-stressed and non-stressed plants of the eight almond species. In all the species, salt stress significantly enhanced the activities of SOD and POD, levels of total phenolics and γ- and δ-tocopherols. High levels of salt stress significantly depressed the levels of total soluble proteins, MDA and CAT activity, while salt stress did not significantly affect leaf H2O2 contents. Regression analysis showed that the relationship between salt levels and total soluble proteins, CAT, γ-tocopherol, MDAeq, SOD and POD were statistically significant. Principal component analysis discriminated the almond species on the basis of their degree of tolerance/sensitivity to saline conditions: Prunus reuteri and P. glauca were ranked as salt tolerant, P. lycioides and P. scoparia as moderately tolerant, and P. communis, P. eleagnifolia , P. arabica and P. orientalis as salt sensitive. The results could be used for selecting salt tolerant genotypes to be used as rootstocks for almond cultivation

RESUMEN Composición química de aceites de almendras (Prunus scoparia) y pistachos silvestres (Pistacia atlantica)El objetivo de este estudio fue determinar la composición en ácidos grasos, esteroles, triglicéridos, así como tocoferoles, fenoles totales y pigmentos de aceites de almendras y pistachos silvestres prensados en frío. Triglicéridos (TAG), tocoferoles y pigmentos se analizaron mediante HPLC, los áci-dos grasos y esteroles mediante cromatografía de gases, y los fenoles totales espectrofotométricamente. Los principales ácidos grasos de ambas especies fueron los ácidos oleico, linoleico y palmítico. Las especies de TAG predominantes son SLL + OLP (21,83%) en el pistacho silvestre y OOO (47,27%) en almendras silvestre. Feofitina a es un pigmento importante en los aceites de pistacho silvestre. No se detectó pigmentos en los aceites de almendras silvestres. Los fenoles totales fueron 57,6 mg kg -1 y 45,3 mg kg -1 en los aceites de pistacho silvestre y de almendra silvestre respectivamente. PALABRAS CLAVE: Aceite de almendra Silvestre -Aceite de pistachio -Aceite prensado en frío -Ácidos grasosEsteroles -Fenoles Totales -Triacilgliceroles -Tocoferoles. SUMMARY Chemical composition of oils from wild almond (Prunus scoparia) and wild pistachio (Pistacia atlantica)The aim of this study was to determine the fatty acids, sterols and triacylglycerol compositions as well as the amount of tocopherols, total phenols and pigments wild almond and cold pressed wild pistachio oils. Triacylglycerols, tocopherols and pigments were analyzed with HPLC, fatty acids and sterols with gas chromatography, and total phenols photometrically. The main fatty acids in both samples were oleic, linoleic and palmitic acids. The most predominant TAG species are SLL + PLO (21.83%) in wild pistachio oil and OOO (47.27%) in wild almond oil. Pheophytin a was the major pigment in wild pistachio oil. There were no pigments detected in wild almond oil. Total phenols were 57.6 mg kg -1 oil for wild pistachio and 45.3 mg kg -1 oil for wild almond oil. KEY-WORDS: Cold pressed oil -Fatty acid -SterolTocopherol -Total phenol -Triacylglycerol --Wild almond oil -Wild pistachio oil.

“…Here, we present the complete and annotated DNA sequences of the cp genomes of five almond resources. Our research purposes were as follows: (1) to study the overall structure of the cp genomes; (2) to detect the variations in the repeat sequences and the simple sequence repeats (SSRs) in the six almond cp genomes; (3) to screen rapidly evolving DNA regions in the six chloroplast genomes; and (4) to analyze the phylogenetic relationship using the sequence data of the chloroplast genome. These results will supply rich molecular tools for further phylogenetic analysis, population genetics analysis, and species identification and will contribute to almond breeding.…”

As a source of genetic variation, almond germplasm resources are of great significance in breeding. To better reveal the mutation characteristics and evolution patterns of the almond chloroplast (cp) genome, the complete cp genomes from six almond species were analyzed. the lengths of the chloroplast genome of the six almond species ranged from 157,783 bp to 158,073 bp. For repeat sequence analysis, 53 pairs of repeats (30 bp or longer) were identified. A total of 117 SSR loci were observed, including 96 polymorphic SSR loci. Nine highly variable regions with a nucleotide variability (Pi) higher than 0.08, including rps16, rps16-psbK, atpF-atpH, rpoB, ycf3-rps4, rps4-ndhJ, accD-psaI and rps7-orf42 (two highly variable regions) were located. Based on the chloroplast genome evolution analysis, three species (P. tenella, P. pedunculata and P. triloba) and wild cherry (P. tomentosa) were grouped into clade i. clade ii consisted of two species (P. mongolica and P. tangutica) and wild peach (P. davidiana). clade iii included the common almond (P. dulcis), cultivated peach (P. persica) and GanSu peach (P. kansuensis). this result expands the researchers' vision of almond plant diversity and promotes an understanding of the evolutionary relationship among almond species. In brief, this study provides abundant resources for the study of the almond chloroplast genome, and has an important reference value for study of the evolution and species identification of almond. The common almond (Prunus dulcis (Mill.) D.A.Webb), a member of the family Rosaceae and order Rosales, is widely and mainly distributed in the temperate zones of Europe, America, and Asia 1,2. Among the different varieties of tree nuts, almonds are the second most consumed worldwide, behind peanuts. In 2018, the volume of almonds consumed worldwide amounted to 1.19 million metric tons 1. In addition to common almonds, there are more than thirty almond species in the world, including partially cultivated and wild varieties 2. Five wild almond resources have been reported in China, including the diploid species wild almond (Prunus tenella Batsch), Mongolic almond (Prunus mongolica Maxim.), and Tangut almond (Prunus tangutica (Batalin) Koehne), the octoploid species, flowering almond (Prunus triloba Lindl.), and the dodecaploid species, longstalk almond (Prunus pedunculata (Pall.) Maxim.) 3-6. All the almond species are highly adapted to a cold and dry climate, which may indicate an important gene pool. Therefore, it is of great significance to identify the almond genetic resources and evaluate their industrial application value for effective utilization and preservation. Wild almond species usually grow in areas of altitudes between1,100 m and 2,700 m and at latitudes between 28 and 38 N and longitudes between 41 and 54 E 7,8. It is reported that there are five wild species in China, indicating that China is one of the central origins of almonds 4,5,7. Based on taxonomy, wild almond species and the common almond were classified as a separate genus, Amygdalus L....
