Avocado (Perseaamericana Mill.) is cultivated and used as food in most tropical andsubtropical countries. Its high nutritional value and biological activities,as antioxidant, antimicrobial and analgesic properties, have beenthoroughly investigated. Interest in plant extracts with antimicrobialproperties has increased as a result of the indiscriminate use ofantibiotics, leading to the emergence of resistant bacterial strains.Among bacterial species with clinical importance to multiple hosts,Streptococcus agalactiae is outstanding, as it can cause infections especiallyin humans, fish and cattle. The current study aimed to evaluatethe antimicrobial activity of two extracts (ethanol and dichloromethane)from avocado seeds, ‘Margarida’ variety, against isolates of S.agalactiae. Extracts were diluted in ethanol / water (1:1) at a concentrationof 100 mg/mL. Antimicrobial activity was tested by thedisk diffusion method (antibiogram) against isolates of S. agalactiaeof human and fish origin.The ethanol extract showed antimicrobialactivity only for some isolates of S. agalactiae of human origin. Thedichloromethane extract showed activity against all isolates of S. agalactiaeof both origins. A comparison of the results obtained with dichloromethaneextract from isolates of S. agalactiae of human or fishorigin demonstrated the existence of phenotypic variability amongisolates from the same host. However, when comparing measurementsobtained in each of the groups, they were statistically similar,showing a lack of interpopulation variability. Thus, it can be verifiedthat the resistance profile of isolates of S. agalactiae was independentof host origin and typical of the species.","PeriodicalId":20184,"journal":{"name":"Phyton-international Journal of Experimental Botany","volume":"99 1","pages":"218-224"},"PeriodicalIF":1.7,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74991070","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}

Previous studies on transformed plants with the PttKN1 gene suggested that it plays roles in plant development (typically in meristem initiation), maintenance and organogenesis in simple-leaved species. To investigate the gene functions further, sequence analysis of the deduced amino acid was conducted. The results suggested that the gene belongs to the class I KNOX gene (KNOTTED1-like homeobox genes) family and might play important roles in plant development by coding a transcription factor. The gene was introduced into Cardamine hirsuta using the floral dip method mediated via Agrobacterium tumefaciens. The primary transformed plants were obtained via kanamycin selection. Compared to the wild type, the kanamycin resistant plants demonstrated several morphological alterations, such as abnormal cotyledons, abnormal shoot meristem, flattened stem, and lobed and cup-shaped leaves. RT-PCR results showed that the above five types of kanamycin resistant plants expressed the same specific PttKN1 gene band. This suggested that the morphological alterations were caused by the insertion and expression of the gene. However, these phenotypes were similar to other PttKN1 transformed plants, despite the fact that C. hirsuta is a species with compound leaves and the other species have simple leaves. Therefore, the functions of the PttKN1 gene on compound-leaf species have yet to be investigated via the comparison between related species such as Arabidopsis thaliana and C. hirsuta.","PeriodicalId":20184,"journal":{"name":"Phyton-international Journal of Experimental Botany","volume":"26 1","pages":"368-374"},"PeriodicalIF":1.7,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81135585","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 subsurface drip irrigation (SDI) and changes in population density of plants are alternatives that can be used to make a sustainable use of water. Therefore, the objectives of this study were to determine the combination that allows for an increased corn performance and efficient use of water without losing the quality of forage. Three different irrigation levels were applied through a system of a SDI at three different densities of forage maize plants in an arid region. The results demonstrated that by applying different levels of water, either enough or lack of soil moisture is created, which is directly reflected in crop yield, and its determining variables such as green forage and dry matter yield, and nutritional quality. The irrigation level to a 100% of potential evapotranspiration (PET), at a density of 80000 plants/ha, increased yield of green forage to 57664 kg/ha; crude protein was 8.59%, while the rest of the quality parameters decreased. This study allowed to conclude that the irrigation level was the major factor in the response of the crop.","PeriodicalId":20184,"journal":{"name":"Phyton-international Journal of Experimental Botany","volume":"1 1","pages":"272-279"},"PeriodicalIF":1.7,"publicationDate":"2016-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85738112","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}
