This study examines the cytotoxic and genotoxic effects of T. terrestris using two plant models, Allium cepa and Vicia faba. Extracts of 0.00625, 0.0125, 0.025, 0.05 and 0.1mg/mL were tested on meristematic cells of A. cepa and V. faba roots. This assessment includes the study of root growth, structure and coloration, as well as the determination of the mitotic index (MI) and chromosomal aberrations (CAs) as accurate indicators of toxicity. Our results showed a significant decrease in the mean length of roots treated with 0.025, 0.05 and 0.1 mg/ml for A. cepa and 0.1 mg/ml for V. faba. Cytotoxicity and genotoxicity results showed a significant decrease in MI from 0.025 mg/ml in A. cepa and from 0.05 mg/ml in V. faba, and this decrease in MI is linked to the increase in concentration and treatment time with T. terrestris. Furthermore, a significant increase in CAs was observed in A. cepa and V. faba from the 0.025 mg/ml concentration. The significant reduction in MI and CAs abundance suggests the genotoxicity of T. terrestris. Therefore, T. terrestris is a medicinal plant that should be used with caution, appropriately and based on essential therapeutic needs.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110197","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}

Experimental treatments included different irrigation regimes (90% FC, 65% FC, and 40% FC) and foliar application of different elicitors (control, chitosan, salicylic acid, and melatonin). In this study, the content of chlorophyll A and b was reduced by intensifying the water deficit stress. Also, the highest content of the two pigments was allocated to the treatment of melatonin application. In the present study, melatonin foliar application under 90% FC irrigation conditions had the highest plant height, leaf area index, biomass, and carotenoid content, Moreover, the highest content of proline, phenol, DPPH, rebaudioside A, and steviosid was assigned to melatonin foliar application treatment under 40% FC irrigation conditions. Results revealed, although water stress reduced plant height, leaf area index, and plant biomass, the application of melatonin and salicylic acid under different irrigation conditions moderated the effect of water stress on these traits. Application of melatonin and salicylic acid under water deficit stress conditions also increased the content of proline, phenol, DPPH, rebaudioside, and steviosid.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79814728","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}

Results showed that the studied plant continued to uptake nitrate and potassium under stress conditions of Pb and salinity. Although Na and Cl uptake were observed as a defense mechanism in the plant, the K/Na ratio, and K content increased from 1 to 6 and from 1.8 to 5%, respectively. Also, the most appropriate physiological responses were observed at treatments under contamination level of 300 mg Pb and salinity level of 3 dSm-1, so that the synthesis of malondialdehyde (MDA) and enzymatic activity increased at these levels of HMs and salinity. Based on the results, the studied species were able to uptake moderate concentrations of Pb (34.1-71mg kg-1) under experimental conditions. Hence, its potential for the clean-up of some contaminants in the environment can be considered by researchers for further research.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82298129","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}

Herein, we describe the karyotypes of red-eyed Gecko (Gekko nutaphandi Bauer, Sumontha & Pauwels, 2008) from Thailand. Gecko chromosome preparations were directly conducted from bone marrow and testis. Chromosomal characteristics were analyzed by Giemsa staining, Ag-NOR banding as well as fluorescence in situ hybridization (FISH) using microsatellites d(GC)15 probe. The results showed that the number of diploid chromosomes is 2n=34, while the fundamental number (NF) is 46 in both males and females. The types of chromosomes were 4 large metacentric, 6 large submetacentric, 2 medium telocentric, 2 small metacentric and 20 small telocentric chromosomes. The results of conventional Giemsa staining presented the diploid chromosome number differentiation even in the same genus. NORs are located at the secondary constriction to the telomere on the long arm of chromosome pair 5. There are no sex differences in karyotypes between males and females. FISH with d(GC)15 sequences were also displayed at the telomeres of most other chromosomes. We found that during metaphase I the homologous chromosomes showed synapsis, which can be defined as 19 ring bivalents and 17 haploid chromosomes (n=17) at metaphase II as a diploid species.

Despite the considerable breeding, selection, widespread cultivation and domestication, which may have a significant role in the composition of genomes, there are no other previous reports of intraspecific genome size variation in the different cultivars or hybrids of this species. In the present work, genome size of 12 varieties of I. cornuta was assessed and analyzed through high-resolution flow cytometry (FCM). Nuclear DNA was analyzed using nuclei isolated from young leaves, which used propidium iodide (PI) staining, with rice (Oryza sativa cv. Nipponbare) as internal reference. As a result, statistically significant differences in genome size were detected among all diploid I. cornuta varieties considered. The estimated genome size (2C value) of I. cornuta varieties ranged from 1.47 to 1.80 pg, with 1.22-fold variation and an average size of 1.65 pg. The domestication and interspecific hybridization induced variation of genome size in I. cornuta, and the genome size of hybrids exhibited a wider range of variation compared with that of cultivars. In summary, flow cytometry is a useful tool to analyze the genome size of I. cornuta. The first report of the genome sizes of varieties of this species would provide useful data for further research on I. cornuta, and enrich the C value database of Ilex L. What’s more, our findings could be the foundation in the future of I. cornuta genome sequencing and breeding programs.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90805269","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}

In this study, morphological and cytogenetic traits were evaluated in a hybrid obtained using Aloe jucunda Reyn. as pollen donor and A. vera (L.) Burm. f. as female parent, to characterize it, determine its ornamental and agronomic potentialities and aspects related to its reproduction. Conventional protocols for morphometric studies and cytogenetic analysis described for succulent plants were applied. Progeny showed intermediate expressiveness in most of the characteristics, except in the colour of the leaves and flowers (hybrid = A. jucunda), as well as for the length of teeth, number, and area of leaf spots and angle between continuous leaves, where it surpassed the expression of both parents, giving it a high ornamental value. The length, width, and thickness of the leaves improved with respect to the paternal genome, so its potential for the exploitation of the gel and latex of its leaves cannot be ruled out. Root tip cells showed a karyotype 2n = 2x = 14 = 8L + 6S = 1L(smsat) + 1L(sm) + 3L(st) + 3L(smsat) + 1S(m) + 5S(sm). Microsporogenesis showed chromosomal abnormalities in 47.4% of the meiocytes, the most frequent being micronuclei in prophase-I, sticky chromosomes in metaphase-I, one or two dicentric bridges accompanied or not by acentric fragments in anaphase-I, -II, and telophase-I, - II, as well as one or two additional microspores. These abnormalities reduce the fertility of their pollen grains and limit their sexual reproduction, providing a better explanation for their sterility.","PeriodicalId":9634,"journal":{"name":"Caryologia","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84127969","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}
