A previous analysis showed that Gammaproteobacteria could be the sole recoverable bacteria from surface-sterilized nodules of three wild species Hedysarum. In this study we extended to eight Mediterranean native, uninoculated legumes never previously investigated regarding their root-nodule microsymbionts. The structural organization was studied by light and electron microscopy, bacterial occupants were assessed combined cultural molecular approaches. On examination 100 field-collected...
Objetivo: Este protocolo de revisão sistemática visa analisar a prevalência da Síndrome Burnout entre professores. Método: Registrado na PROSPERO (CRD420250651910) e seguindo as diretrizes PRISMA, incluirá estudos observacionais (transversais, coorte caso-controle) que utilizem instrumentos validados. A busca será realizada nas bases MEDLINE (PubMed), EMBASE, LILACS (BVS), PsycInfo Google Acadêmico. seleção extração dos dados serão feitas por dois revisores independentes, com um terceiro...
ABSTRACT In many coastal areas, synthetic surfactants are present as pollutants in the chemical composition of sea spray. Their phytotoxic action synergism with salt is well known. This paper examines early effects an anionic surfactant (sodium alkylbenzene sulphonate = ABS) on anatomy and ultrastructure Pinus pinea L. needles. Three successive treatments open field trees about 2 m height were carried out month August. The crowns sprayed aqueous solution containing 1000 g −3 , subsequently...
Hydration, rupture and exine opening due to the sudden large expansion of intine are typical taxoid-type pollen grains. A hemispheric outgrowth external was observed on Cupressus Juniperus grains before swelling release. However, actual existence this permanent or temporary structure its precise role in hydration is still being debated. The aim paper collect information presence peculiar surface grain, structure, composition function. Pollen several species were using various techniques...
The manner in which the bacterium Pseudomonas savastanoi pv. ( Pss ), causal agent of knot disease, infects olive plants is erratic and has not been fully documented. To investigate process invasion, explants were inoculated vitro examined visually by light microscopy at 2‐weekly intervals for 10 weeks. In all host genotypes tested, interaction with pathogen resulted in: (i) a progressive collapse stem, originating inoculation site apex explant, proceeding downwards; (ii), localized...
This work presents the effects of an anatoxin-a(s)-containing extract on a cockroach semi-isolated heart preparation and results supporting extract's biological activity acetylcholinesterase (purified from ell). The presence toxin in cyanobacterial strains Anabaena spiroides (ITEP-024, ITEP-025 ITEP-026) isolated Tapacurá reservoir Pernambuco, Brazil, was confirmed by means liquid chromatography coupled to ion-trap mass spectrometer. anticholinesterase assessed biochemically Ellman test...
Histochemical reactions of one-year-old potted micropropagated vines (rootstock 1103 Paulsen) to inoculation with Phaeomoniella chlamydospora were studied. Microscopic examination the vine wood showed that the fungus spread through tissue, albeit slowly. Starting from roots it required nine months colonise the first 20-25 cm grapevine stems. The slow P. is thought be due defence response initiated by vines: production tyloses, including accumulation phenols in vessels and adjacent tissue,...
A simple method to enhance the staining of cell wall components for fluorescence microscopy is described. In stems Nicotiana tabacum and needles Pinus eldarica lignin, cuticle unsaturated lipids are indicated by a purple-red while pectocellulosic fluoresce pale blue.
SummaryThe effects of rain acidity on fruit field-grown apple trees (Malus domestica Borkh) cv. Summerred were investigated. One group four was exposed to ambient rainfall, while other groups covered with shields and received simulated consisting deionized water or an acid solution at pH 5.6, 4.0 3.0. SEM examination showed alterations the cuticular wax russeting skin. Formation a cambium, which in turn brought about formation phellem layer as substitution for damaged epidermis hypodermis,...
Cerato-platanin (CP) is a purified protein isolated from the culture filtrate of ascomycete Ceratocystis fimbriata f. sp. platani (Cfp), causal agent canker stain disease plane. The responses cells/tissues plane leaves to CP was studied by light microscopy (LM) and transmission electron (TEM) using two experimental procedures. most significant occurred already at 24 h after treatments, were also visible at 48 h. main effects cause great increase in primary starch certain degree...
La solvabilité d'une entreprise est généralement référée à des vérifications d'ordre patrimonial et financier, considérations de nature économique (relatives l'entreprise en elle-même, son avenir, au milieu dans lequel elle opère, marché dont constitue une unité élémentaire), relèvements, constatations, informations même caractère subjectif personnel. En d'autres termes, se définit sur la base d'un ensemble d'éléments “réels”, mais aussi facteurs diversement constitués déterminés qui...
A simple and efficient protocol for in vitro shoot regeneration from storage root expiants of witloof chicory (Cichorium intybus L.) has been used to study the effect colchicine at different concentrations, combination with kinetin or 2,4-D kinetin, comparison control (no treatment), upon this type morphogenic event. The results demonstrated a strong stimulatory low concentration on frequency when compared number shoots formed control. This was comparable that growth regulator induces...
In the discussion of this paper ( page 305) authors state: 'In conclusion, whereas Duhoux (1982) and Chichiricco `and Pacini (2008) believe that bulge is an intinic protuberance produced as artefact calcofluor, we show can be revealed by various staining techniques'.Following correspondence with Dr `the would like to amend sentence read: conclusion
