The genus Pistacia consists of eleven species that only have edible nuts and are commercially important. Four important species of pistachios include Pistacia vera, P. khinjuk Stocks, P. eurycarpa Yalt. (P. atlantica subsp. Kurdica Zoh.), and P. atlantica Dsef are found in Iran. Genetic diversity is one aspect of biological diversity that is extremely important for conservation strategies, especially in rare and narrowly endemic species. In Iran, there is no knowledge concerning the genomic organization of the population, genetic diversity, or phenotypic variations of the species. Pistacia khinjuk has eight distinct regional populations, all of which were studied for genetic variation and demographic organization because of the species’ therapeutic value. For this reason, we employed six inter-retrotransposon amplified polymorphism (IRAP) indicators and 15 mixed IRAP indicators to highlight genomic variation in this plant both within and across populations in this study. It was discovered that 73% of overall genomic variability was related to within-population variety and 27% was attributable to inter-population genomic divergence using the AMOVA test among the examined populations (PhiPT = 0.49, P = 0.010). It was discovered by the Mantel analysis that there was a substantial positive association between genomic isolation and geographic distance among the tested populations. STRUCTURE analyses and population assignment tests revealed some degree of gene flow among these populations. There was consistency between the MDS plots of communities and the NJ grouping of molecular information. Based on (IRAP) indicators, these findings demonstrated that regional communities of the plant Pistacia khinjuk are well distinct.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":"82 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79333639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of modern techniques such as “karyotyping” has made it feasible to visualize undetected chromosomal abnormalities such as short chromosome segments and chromosome translocations. Because such techniques enabled each pair of chromosomes to be identified separately, they have further aided our understanding of the chromosomal basis of a certain significant genetic diseases. Every organism has its own unique karyotype, which is defined by its number and shape. Karyotypic variation, on the other hand, occurs in different individuals of the same species, as well as between different species.

To induce polyploidy, two-leafed seedlings were exposed to different concentrations (0.00, 0.05, 0.1, and 0.2 % w/v) and durations (6, 12, and 24 h) of colchicine.

There is no information on its population genetic structure, genetic diversity, and morphological variability in Iran. Due to the medicinal importance of this species, a genetic variability and populations’ structure study is performed studying 15 geographical populations of Medicago polymorpha. Therefore, we used six inter-retrotransposon amplified polymorphism (IRAP) markers and 15 combined IRAP markers to reveal within and among population genetic diversity in this plant. AMOVA test produced significant genetic difference (PhiPT = 0.46, P = 0.010) among the studied populations and also revealed that, 66% of total genetic variability was due to within population diversity while, 34% was due to among population genetic differentiation. Mantel test showed positive significant correlation between genetic distance and geographical distance of the studied populations.

Two thousand cells were counted per treatment; the mitotic index (MI) and nuclear abnormalities (NA) were evaluated. Data were analyzed using variance analysis (ANOVA) and Chi square (X2) (p < 0.05). Root growth was found to be inhibited based on the concentration with statistically significant differences (p < 0.05). As the dose and exposure time of the ethanol extract increased, the MI decreased. The NA increased at the highest concentrations of 500, 1000 and 1500 mg/L and these differences were statistically significant compared to the control (p = 0.001). With the results obtained, it can be shown that the species has antiproliferative effects and genotoxic activity on the Allium sativum cell cycle, which can be extrapolated to other types of eukaryotic cells. Therefore, despite being a plant with health benefits, moderate use and low concentrations are recommended to avoid harmful effects.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":"15 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78991453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
