“…For preventing ROS damage to the cellular components, numerous detoxification systems have been evolved by plants, like the synthesis of antioxidating molecules and enzymes. A reduction in oxidative damage and higher resistance to salinity was attributed to the effective antioxidant systems in O. basilicum (Alhasnawi 2019b). It was also seen that the SA application increased the POD, CAT, and SOD activities; and decreased the ROS levels and the oxidative damage to the membranes, hence was regarded as a vital component for improving salt tolerance in O. basilicum (Alhasnawi 2019b).…”

The mutant and the transgenic plants that overexpressed the antioxidant enzymes showed higher ability to scavenge the ROS molecules, thus, increased the salt tolerance.…”

Abstract. Alhasnawi AN. 2023. Genetic stability analysis associated with salt stress and salicylic acid in fenugreek (Trigonella foenum-graecum) plants. Biodiversitas 24: 3601-3608. Salt damage to plants has been attributed to a combination of many factors like the accumulation of toxic metal ions or osmotic stress. This study attempted to understand the mitigating effects of the salicylic acid (SA) treatment on the salt-stressed seed germination ability of the fenugreek plants (Trigonella foenum-graecum); SA pre-treatment along with the salt tolerance capacity have also been tested. The effects of salinity and applied SA on biochemical traits and genetic stability of plantshave been estimated in this study. Respective molecular and biochemical changes occurring in plants as well as genetic analysis have been performed. The results indicated that exogenous application of SA(0.4 mmol) improved the biochemical traits in the seedlings. The evaluation of the genetic stability of the plants was also conducted. Whereas DNA marker-based genetic stability estimates are considered a reliable, accurate, and advanced technique.The Inter-Simple Sequence Repeats (ISSR) analysis has been performed with the help of 7 ISSRs primers. The 6 ISSRs primers generated 54 fragments in total, with an average of 4.5 bands for every primer. The ISSR did not reveal any polymorphic bands. Finally, it has been concluded that exogenous SA can be effectively used as a potential growth regulator for improving the biochemical traits and salinity stress tolerance of the fenugreek plants and stimulating its medicinal properties. Furthermore, ISSR markers were seen to be a good tool as potential diagnostic markers for testing the genetic stability of plants.

Selection signatures and population dynamics of transposable elements in lima bean

et al. 2023

The domestication process in lima bean (Phaseolus lunatus L.) involves two independent events, within the Mesoamerican and Andean gene pools. This makes lima bean an excellent model to understand convergent evolution. The mechanisms of adaptation followed by Mesoamerican and Andean landraces are largely unknown. Genes related to these adaptations can be selected by identification of selective sweeps within gene pools. Previous genetic analyses in lima bean have relied on Single Nucleotide Polymorphism (SNP) loci, and have ignored transposable elements (TEs). Here we show the analysis of whole-genome sequencing data from 61 lima bean accessions to characterize a genomic variation database including TEs and SNPs, to associate selective sweeps with variable TEs and to predict candidate domestication genes. A small percentage of genes under selection are shared among gene pools, suggesting that domestication followed different genetic avenues in both gene pools. About 75% of TEs are located close to genes, which shows their potential to affect gene functions. The genetic structure inferred from variable TEs is consistent with that obtained from SNP markers, suggesting that TE dynamics can be related to the demographic history of wild and domesticated lima bean and its adaptive processes, in particular selection processes during domestication.

“…Of late, DNAbased markers have been extensively utilised for clarifying the genetic relationship between the apricot accessions (Romero et al, 2003;Barakat et al, 2012;Yilmaz & Paydas-Kargi, 2012). Lately, AFLP (Krichen et al, 2006;Yuan et al, 2007;Volkova et al, 2020), ISSR (Alhasnawi et al, 2017;Alhasnawi, 2019;Bhadkaria et al, 2020;Xiang et al, 2020), SSR (Maghuly et al, 2005;Chiou et al, 2020;Cmejlova et al, 2020) and SRAP (Uzuni et al, 2010;Xiang et al, 2020). Methodologies have often been utilised in apricots to portray diverse genotypes pertaining to varied ecogeographical groups.…”

Employing DNA markers allowed determining genetic diversity and relationships amongst five apricot genotypes. In this study, two relative gene expressions pertaining to ParARF3 gene, which could be distinguished from the genotypes that were exposed to various concentrations of marine alga treatments. As per our results, screening of seven primers with the DNA of 5 apricot genotypes was done, and six primers were generated while the primer OPN–16 gave negative results. The total quantity of fragments generated by 6 primers was 80 at an average of 13.33 fragments ̸primer. The highest unique percentage band depicted in U-17 touched 23%, and the total number of polymorphic bands touched 17 fragments with the average reaching 2.83 fragments ̸primer. The number of monomorphic lied in the range of 5 to 10, with a total of 47 monomorphic. Primer M 32 yielded the highest number of monomorphic bands reaching 10. Between Zaghenia and Zinni, a maximum genetic distance value of 0.8 was reached with less similarity value of 20%. A minimum genetic distance value of 0.44721 was noted between Kaisy and Baia while the high similarity value touched 55.3%. According to the cluster tree analysis, the genotypes were generally split into two key groups: A and B. The Zinni group, which included one apricot genotype, showed genetic similarity of 20% with the other genotypes present in B group. The B group was split into two sub-clusters B1 and B2 and the genetic similarity reached 44%. The ParARF3 relative gene expression pertaining to Zinni genotypes was second as well as convergent with that of gene expression for Zaghenia genotype results. Baia and Kaisy genotypes lied in between the lowest and highest ParARF3 value gene expression exposed to Marine Alga. These outcomes showed that RAPD markers offer an effectual alternative for the plant species genetic characterisation.
