| ABSTRACT Cassava is an important culture in Brazil and in the North of the country, and soft root rot has affected root production. The aim of this work was to identify root morphoanatomic and histochemical characters associated with root rot resistance. In areas with no occurrence of the disease, nine cassava genotypes were tested, four of which were resistant, and five were susceptible to root rot. Root harvest was carried out twelve months after sowing, and thickness of suber, suber and cortex, and secondary xylem were measured. Moreover, texture, suber cell layers, lignin content, and lignin monomers content of the portion suber and cortex were analyzed. Also, histochemical tests and scanning electron microscopy (SEM) analyses of the roots were... |

| ABSTRACT Dipteryx, Pterodon and Taralea are legume genera known for secreting oils, produced in secretory canals and cavities, with medicinal properties. We analyzed the distribution, morphology and histochemistry of these glands in leaves and stems of Dipteryx alata, Pterodon pubescens and Taralea oppositifolia, three Neotropical species, using standard techniques for anatomy and histochemistry. Secretory spaces, i.e. secretory cavities and canals, exhibited a wide lumen and a single layer of epithelium. Digitiform epithelial cells, forming trabeculae protruding into the lumen, were seen in all three species. Secretory cavities with a rounded or oval lumen and secretory canals with an elongated lumen in longitudinal sections were found only in T.... |

| ABSTRACT This study aimed to obtain new information about the distribution, morphology and content of secretory trichomes present in the vegetative and reproductive organs of four species of Moraceae: Artocarpus heterophyllus, Dorstenia cayapia, Maclura tinctoria and Sorocea bonplandii. Stem, leaf, flower and inflorescence samples were processed for scanning electron and light microscopy. The species have secretory trichomes on the leaf blade, petiole and stem and also on the inflorescence and flowers of D. cayapia and S. bonplandii and on the peduncle of the inflorescence in A. heterophyllus. These trichomes are of the capitate type in all species, but A. heterophyllus also possess peltate secretory trichomes. Both trichome types exhibit a multicellular... |

| ABSTRACT Species of Apocynaceae stand out among angiosperms in having very complex flowers, especially those of asclepiads, which belong to the most derived subfamily (Asclepiadoideae). These flowers are known to represent the highest degree of floral synorganization of the eudicots, and are comparable only to orchids. This morphological complexity may also be understood by observing their glands. Asclepiads have several protective and nuptial secretory structures. Their highly specific and specialized pollination systems are associated with the great diversity of glands found in their flowers. This review gathers data regarding all types of floral glands described for asclepiads and adds three new types (glandular trichome, secretory idioblast and... |

| Using conventional techniques for structural studies under conventional microscopy, polarizing light microscopy and scanning electron microscopy this work describes and compares the thallus anatomy of two Parmotrema species with reticulate maculae, previously included in the genus Rimelia: Parmotrema cetratum (Ach.) Hale and P. clavuliferum (Räsänen) Streimann. The data showed that the species are anatomically similar, including the presence of epicortex, the upper cortex anatomy and the characteristics of rhizines and ciliae. In the medulla of the two species there are star-shaped clusters of hyphae associated with the presence of salazinic acid. This study showed that the anatomical characteristics are constant for the Parmotrema group studied. |

| This study aims to give an overall view of fruit structure in Bromeliaceae, since these studies are extremely scarce in this family, showing the morphology, anatomy and ontogeny of fruits of six species belonging to six different genera, representing three subfamilies. All species studied have a tricarpellary and trilocular ovary, with an obturator covering the placental region. Dyckia maritima, Pitcairnia flammea, Tillandsia aeranthos and Vriesea carinata have capsular fruits (septicidal or biscidal), characterized mainly by the presence of macrosclereids in the exocarp or endocarp, fibers in the ventral region of the carpels, six dehiscence lines and three vascular bundles in each carpel. Aechmea calyculata and Billbergia nutans have fruits classified as... |

| Aspects of the morpho-anatomy of developing fruits and seeds of Clusia parviflora are presented and discussed as a continuation of the study of these organs in Clusiaceae. The fruit is a septifrage capsule; the suberized exocarp is derived from the external epidermis of the ovary. The mesocarp originates from the ovarian mesophyll and remains parenchymal in nature. The endocarp is derived from the internal epidermis of the ovary and the endocarp is derived from the inner ovary epidermis as well as from three to four adjacent subepidermal layers, with tangentially elongated cells which become lignified and contribute to fruit dehiscence. The ovules are anatropous, bitegmic, with an endothelium, and give rise to equally anatropous seeds. The exotesta has... |

| ABSTRACT Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. This study aimed to show the diversity of secretory structures present in the developing flowers of 15 legume species belonging to different clades and to associate them with functions other than the pollinator attraction. Buds, flowers and developing axis of inflorescence were processed for surface, histological, and ultrastructural analyses. The species investigated displayed a wide diversity of secretory structures in developing flowers such as phenolic cells and/or tissues, mucilaginous cells, secretory cavities, secretory trichomes and colleters. Each type of secretory structure... |

| ABSTRACT Charcoal is widely accepted as evidence of the occurrence of palaeo-wildfire. Although fossil charcoal remains have been used in many studies, investigation into the anatomical changes occurring during charring are few. The present study analyses changes in selected anatomical characters during artificial charring of modern wood of three species of the genus Araucaria (i.e. Araucaria angustifolia, Araucaria bidwillii and Araucaria columnaris). Wood samples of the studied species was charred under controlled conditions at varying temperatures. Measurements of anatomical features of uncharred wood and artificial charcoal were statistically analysed. The anatomical changes were statistically correlated with charring temperatures and most of the... |

| ABSTRACT This study presents a morphoanatomical analysis of Dyckia ibicuiensis , D. polyclada and D. racinae stamens. Flowers at anthesis were desiccated and their stamens were processed using common light microscopic techniques. Morphologically, the androecium in these species is differentiated by the disposition of the stamens around the gynoecium and by general anther characteristics. Included stamens, with antesepalous filaments different from those of the antepetalous, anthers in a radial disposition, always curved, and sporangia facing the gynoecium characterize D. ibicuiensis and D. racinae . This configuration results from the filament connation, as well as special anatomical characteristics of the anthers, such as the connective with thickenings.... |

| Kidneys are especially irrigated by a pair of arteries originated from the aorta artery. The presence of additional renal arteries is the most frequent variation in this vascularization, an aspect important to be known in renal surgeries and radiological procedures (SAMPAIO; PASSOS, 1992). This study aimed to observe the prevalence of numeric variation and the origin of the additional renal artery. For this purpose, 24 cadavers and 26 blocks were used; each block contained the kidneys and their respective arteries and veins, the abdominal aorta and inferior vena cava, taken from adults of different ethnicity and genders, from the Department of Morphological Science, State University of Maringá (DCM/UEM) and Laboratory of Anatomy, Ingá Faculty (UNINGÁ).... |

| Procyon cancrivorus is a wild mammal from the Procyonidae family, being one of the least studied Brazilian carnivores. The aim of this study was to describe the morphological aspects of the salivary glands of Procyon cancrivorus, and to compare with literature data on the morphology of domestic animals and wilds animals, such as coatis and possums. Three adult animals were collected on highways (roadkilled), fixed 10% formaldehyde aqueous solution and submitted to desiccation. The salivary glands of the crab-eating raccoon are formed by the parotid, mandibular, sublingual and zygomatic glands. The parotid gland shows irregularly triangular shape with its respective duct. The mandible gland shows rounded outline surrounded by a fibrous capsule with its... |
