Research ArticleOpen accessEvery word in the titleIn vitro Polyploid Induction in Phalaenopsis Aphrodite by PendimethalinPrasetyorini Djarot, Deden Sukmadjaja, Fadya Annisa Chaesarani, SukonoPhalaenopsis aphrodite is a type of orchid with high ornamental and economic value. However, its development for commercial needs in Indonesia is still hindered by the limited availability of varieties. Therefore, enhancing genetic diversity is necessary, one of which is through polyploid induction. Several previous studies reported that pendimethalin effectively duplicates the chromosome numbers of various plant species. The aim … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Aug 2026 · 854 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleStudy on the Polyploidy Induction of Herbicides on Hengshan Astragalus MembranaceusJianxia Liu, Yanmao Gao, Lizhen Liu et al.Studying medicinal polyploid plants is of great significance for the cultivation of traditional Chinese medicine varieties and the extraction of active ingredients. The polyploidization of A. membranaceus (Astragalus membranaceus) was induced using two treatment methods: oryzalin and pendimethalin as mutagens. The results showed that in the same method, the induction effect of polyploidy was affected by the concentration of reagents … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,535 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification of Molecular Markers Differentiating Betula papyrifera and B. pumila Populations from Northern Ontario (Canada)Nastaran Moarefi, Paul Michael, Peter Beckett, Kabwe NkongoloBetula is a polyploid and highly polymorphic genus with several species known to hybridize very readily. This high level of introgression has resulted in hybrid populations where different species are sympatric. The main objectives of the present study were to identify putative hybrids between B. papyrifera and B. pumila in the Greater Sudbury Region (Northern Ontario) and to develop ISSR … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 30 Nov 2018 · 8,057 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProtective Effect of Curcumin Against Hepatic Toxicity Induced by Lithium Carbonate (Li2 Co3)Gehan B.A. Youssef, Ahlam F. Hamoda, Rabab R. Elzoghby et al.The current work was done on four groups of rats (10 for each) to detect the hepato-protective characters of curcumin on the toxicity induced by lithium carbonate. The oral administration of Li2 Co3 for one-month lead to noticeable decrease in the SOD, CAT and GSH while the increase in the GPx and some histological changes in the portal tissues including … …American Journal of Pharmacology and Toxicology, Vol. 14, Issue 1 · 31 Jul 2019 · 7,603 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHepatotoxicity Due to Histamine Trifluoro-Methyl Toluidide, Amthamine, R-(-)-α-Methyl Histamine and Clobenpropit (H1R-H4R-Agonists, Respectively) in Rabbit Experimental ModelTrivendra Tripathi, Aijaz Ahmed Khan, Mohammad Shahid et al.Problem statement: Since in vivo studies looking for toxicological impact of histamine receptors-agonists in experimental models are fragmentary, the present study was designed to delineate the histopathological and biochemical changes in livers of rabbits treated with histamine receptors (H1R-H4R)-agonists. Approach: The cohort comprised of six groups (Group I control and Group II-VI treated) containing five rabbits each. Control-group received vehicle … …Current Research in Medicine, Vol. 1, Issue 1 · 30 Jun 2010 · 8,899 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProteins polymorphism of some populations of Lygeum spartum L. in AlgeriaAbderrezak Djabeur, Meriem Kaid-Harche, Douadi KhelifiLygeum spartum L. represent a natural barrier in the Algerian high plateaus against the advances of sand and turning into a desert. This species has two levels of ploïdy (diploïd cytotype 2n = 16 and polyploidy cytotype 2n = 40). Protein profile of several populations of this species have inter and intra specific variability. The polymorphic bands observed in the … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,093 accessesView PDF Cite
