Antimicrobial activity of the essential oil (EO) Lippia gracilis Schauer over fungi and heliconia endophytic bacteria was evaluated. For Geotrichum candidum; Trichoderma viride; Torula herbarum; Paecillomyces sp.; Fusicoccum P. aeruginens; Curvularia lunata; Aspergillus nidulans; A. flavus; niger mycelial discs were inoculated in PDA medium with (0; 420; 440; 460; 480 e 500 µL L-1). The inhibition percentage 420 L-1 100% for all fungi, except C. lunata niger, which 95.58% 89.40% ,...
Arbuscular mycorrhizal fungi (AMFs) can alleviate salt stress in plants by promoting growth. The mitigating effect of the AMF Gigaspora albida on physiology, growth, and Na⁺/K⁺ balance heirloom maize under different dilutions saline wastewater was evaluated. study conducted a greenhouse completely randomized design (CRD) 3 × 4 factorial scheme, with six replicates. treatments consisted three conditions (M1—control without AMF; M2—plants inoculated G. albida; M3—plants plus soil microbiota)...
Pitaya (Hylocereus undatus and H. costaricensis) is found in the group of exotic fruits its cultivation inBrazil expanding, especially semi-arid region Northeast. In this region, problems water quantity andquality usually cause environmental stresses which limit survival plants, during germination seedlingestablishment. Thus, objective was to evaluate mitigating action pre-germination treatments pitaya seeds undersalt stress. The experiment conducted a completely randomized design, 2 × 6...
Antimicrobial drugs are becoming ineffective given the resistance acquired by microorganisms. As such, it is imperative to seek new antimicrobial molecules that could provide a basis for development of drugs. Therefore, this work aimed evaluate potential and mechanisms action essential oil extracted from leaves Croton blanchetianus (named CbEO) on different fungi bacteria clinical importance in both planktonic biofilm lifestyles. GC-MS/MS analysis revealed presence twenty-two compounds CbEO,...
This study evaluated the effect of salt stress on growth Lippia gracilis Schauer, a species native to caatinga (shrublands) Brazil and rich in essential oils, as well quality its oil. We exposed individuals L. NaCl, following concentrations, for period 40 days: 25 mM; 50 75 100 mM. An additional group plants was not NaCl (controls). Data were collected days 20 40. relative rate; shoot root dry weight; water content; proline concentration leaves; chemical composition At all reduced rate...
Multiresistant pathogens pose a serious threat to human health. The genus Candida is one class of pathogenic yeasts responsible for infections affecting healthy and immunocompromised patients. In this context, plant essential oils emerged as future natural alternative control the diseases caused by these pathogens. Based on that, present study aimed evaluate antimicrobial potential oil from C. pluriglandulosus understand mechanism action. Here, it highlighted activity mechanisms action...

In this context, plant essential oils emerged as future natural alternative control the diseases caused by these pathogens. Here, it highlighted antimicrobial activity mechanisms action oil extracted from Croton pluriglandulosus Carn.-Torres & Riina (CpEO) leaves on microorganisms in planktonic...
The present work evaluated the development of embryogenic callus from transversal ovary sections. experiments were carried out under two experimental regimes using combinations IAA (0; 5.71; 8.56; 11.42; 14.27μM) and 2,4-D 13.57; 18.10; 22.62μM) or with BA 4.43; 6.65; 8.87; 11.09μM). Assessments made anatomical aspects for presence structures cytochemical histological analyses stereomicroscopic scanning electronic microscopic observations. Treatments produced friable calluses demonstrating...
A espécie Lippia gracilis SCHAUER (Verbenaceae) é nativa do Nordeste brasileiro e se destaca pela capacidade de acumular nos tricomas glandulares óleos essenciais com atividade antimicrobiana. Tendo em vista que não constam trabalhos na literatura sobre o estabelecimento in vitro dessa espécie, este trabalho teve como objetivo estabelecer protocolo para micropropagação L. gracilis. Para tanto, ramos contendo folhas foram coletados plantas matrizes no habitat natural a confecção estacas. Em...
Alecrim da Chapada (Lippia gracilis Schauer) é considerada uma planta rica em óleo essencial e possui atividade antimicrobiana comprovada, devido aos monoterpenos fenólicos carvacrol timol. O objetivo deste trabalho foi avaliar o efeito in vitro do dos extratos etanólicos de raízes folhas L. no controle fungo Monosporasccus cannonballus, causador colapso meloeiro. foram testados nas concentrações 2500, 5000 7500 ppm avaliado 255, 340 425 tendo também um positivo com fungicida comercial...
This study aimed to evaluate the antifungal and antibiofilm effects of essential oil (EO) from leaves Lippia gracilis its major constituents, thymol carvacrol, against phytopathogenic fungi. The L. were hydrodistilled obtain EO chemical composition was determined by GC/MS analysis. activity evaluated on vegetative mycelial growth Colletotrichum gloeosporioides, lindemuthianum, Fusarium oxysporum solani. In addition, ability inhibit fungal biofilm formation assessed total biomass...
ABSTRACT The use of saline effluents from fish farming in agricultural activities has been increasing, especially semiarid regions. This study was to evaluate the for irrigation Croton blanchetianus and analyze physiological biochemical responses. After cuttings were planted, with effluent began. Treatments included four salinity levels (control, 1.5, 2.5, 3.5 dS m-1). control treatment supply water (0.56 evaluated variables growth, relative content, dry biomass, proteins, proline, hydrogen...
The effects of thymol and carvacrol the essential oil Lippia gracilis on caulinary shoots heliconia were evaluated. After disinfection, inoculated into MS medium subjected to treatments with 420 µL L-1 (EO) L. gracilis; thymol; carvacrol; 210 carvacrol. control treatment consisted without any phytoregulators. main components EO from are carvacrol, ρ-cimene, thymol. Seven days after initiation experiments, 36.3% necrotized, but 90% exposed EO, thymol, or appeared necrotized. Transmission...
The internal morphology of embryos from immature and mature fruits Heliconia bihai (L.) L. cv. Lobster Claw Two was examined. Embryos were inoculated into MS media (full ½ MS) GA3 (0, 2.5 5 mg L-1) with either sucrose or glucose. These plantlets then replicated transferred to medium 0 L-1 BAP their multiplication evaluated 30 45 days after inoculation. genetic variability the multiplied plants estimated using isoenzyme analyses. revealed tissues be in more advanced stages differentiation...
