Heavy metal contaminants affect the physiological and biological properties of soil and plant health. Zinc (Zn) is an essential micronutrient and it promotes plant growth and development but\u0000a higher concentration of the metal causes reduction in plant growth. The present study was aimed to evaluate the response of Bacillus cereus on maize plants at different concentrations of ZnSO4 (20, 40 and 60 mg kg–1) amended in the soil under pot experiment conditions. The experiment was conducted by using complete randomized design (CRD) with three replications. Higher doses of ZnSO4 inhibited maize growth and nutrient uptake. However, inoculation of maize seeds with Bacillus cereus at 20 mg kg–1 concentration of ZnSO4 increased seed germination about 39% and plant height by 15%. Moreover, 17% increase in leaf length\u0000and a 7% increase in leaf number were observed as compared to control at 20 mg kg–1 concentrations of ZnSO4. Reductions in all growth parameters were observed with 60 mg kg–1 concentration of ZnSO4. The Zn uptake was 75% higher in treatment T8 (uninoculated seeds with 60 mg kg–1 concentration of ZnSO4) as compared to treatments which were inoculated and grown under different zinc concentrations. The results suggest that Bacillus cereus has good potential to remediate Zn from soil as well as to reduce the phyto-availibility and phytotoxicity of zinc.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49615122","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}

Its natural population spreads across gravelly ground and open rocky areas of South and Southwest Anatolia. The current study on in vitro propagation of T. cilicicus focused deeply\u0000on environmental applications such as the development of an optimum medium composition for efficient and genetically stable micropropagation\u0000and improved preservation procedures for long-time conservation of elite germplasms for further studies. For this purpose, MS and OM media were used individually and in combination with cytokinins, charcoal, AgNO3, Fe-EDDHA, and H3BO3. The raw data were statistically analyzed via\u0000the graph kernel method to optimize the nonlinear relationship between all parameters. The optimal proliferation medium for T. cilicicus was OM\u0000supplemented with a combination of 10 g L-1 charcoal and 1 mg L-1 KIN and the calculated averages of the best regeneration rate, the best shoot number and the best shoot length were 96.89%, 3 and 1.24 respectively on this medium. The determination of genetic stability of in vitro grown plants on the optimum medium compositions obtained by the\u0000graph kernel method was carried out with the use of the ISSR-PCR technique. All the ISSR primers produced a total of 192 reproductive band profiles, none of which were polymorphic. Furthermore, the micropropagated plants were successfully rooted and acclimatized to greenhouse conditions. In this study, we present a graph kernel multiple\u0000propagation index which considers all the possible parameters needing to be analyzed. Such an index is used for the first time for the determination of the optimum proliferation medium.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42622994","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}

Studying these strategies allows explaining the survival of these species in such hostile and stressful conditions. In this study we compared some parameters (morphological, physiological and biochemical) of two Brassicaceae species Matthiola tricuspidata (L.) W.T.Aiton, Cakile maritima Scop., and two Fabaceae species Lotus creticus L. and Ononis variegata L., harvested from their natural environment in coastal dunes of Zemmouri El Bahri (Algeria), with the aim to understand their mechanisms of adaptation. The results revealed that C. maritime showed the highest relative water content, leaf area, leaf mass area, and succulence index. Based on the highest levels of total phenols, flavonoids and anthocyanins as well as high contents of photosynthetic pigments, M. tricuspidata can be classified as \"homoiochlorophyllous\" plant. The dry mass content varied considerably among species, with the highest values observed in L. creticus and the lowest in C. maritima. As both Fabaceae species L. creticus and O. variegata showed high chlorophylls, carotenoids, total phenols and flavonoids could also be classified as \"homoiochlorophyllous\" species. The relatively high levels of total phenols, total flavonoids, anthocyanins and carotenoids implies a biochemical adaptation that allows these plants to maintain necessary photosynthetic activity under a water deficiency condition.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.37427/botcro-2021-001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42735214","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}

It usually occurs in synanthopic habitats, represented mainly by urban and suburban roadsides, where it is quite sporadic. Based on current knowledge, it has been hitherto reported only in a few localities of the Mediterranean area, particularly in Morocco, Algeria, Tunisia, Libya, Spain, Portugal, Greece, Turkey, Syria and Crimea. Field observations and herbarium investigations have shown that this species is often mistaken for P. annua, mainly due to its morphological similarities, as well as for the same ecological needs, therefore its real geographical distribution has yet to be verified. Although the two species are both tetraploids (2n = 28), they clearly differ for numerous relevant features concerning the shape and size of ligules, inflorescence, spikelet, glumes, palea, lemma, anthers, lodicules and seed. In order to better clarify the relationships of P. maroccana with P. annua and the other annual species of this genus occurring in the Mediterranean, its carefull a morphological description and iconography is provided, as well as a comparative morphological table of all allied species and also their analytical key for easy identification.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42336300","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}
