Foliar colleters in Macrocarpaea obtusifolia (Gentianaceae): anatomy, ontogeny, and secretion

Wood Anatomy of Some Gentianaceae

Colleters in Caryocar brasiliense (Caryocaraceae) ontogenesis, ultrastructure and secretion.

Colleters are widely distributed and have been reported in several taxa. However, the only report of colleters in the Caryocaraceae family is in Caryocar brasiliense. This study purports to describe the distribution, structure and ultrastructure of colleters in C. brasiliense. Vegetative shoot apices with stipules in different stages of development were collected, fixed, and processed by light,...

Anatomy and ontogeny of kidney development

Introduction Concerns about prenatal diagnosis of congenital renal disease (Morcel et al 2011; Gérard-Blanluet et al 2011; Amsalem et al 2011) and changes in the deterministic background, accounting new risk factors (Sun et al 2010; Harewood et al 2010; Martinovic-Bouriel et al 2010; Dührsen et al 2011, Demirel et al 2011), justify the normal development of the kidneys. Fetal ultrasound examina...

The foliar anatomy and micromorphology of Aloe ferox Mill. (Asphodelaceae).

BACKGROUND The genus Aloe has been the subject of several chemotaxonomic and phytochemical investigations. Aloe ferox is an important source of biologically active compounds like anthrones, chromones, pyrones, and flavonoids. It is a plant used extensively in traditional medicine. Despite the myriad of studies on the pharmacological profile of the plant, there still exists a dearth of scientifi...

Anatomy and ontogeny of Pterodon emarginatus (Fabaceae: Faboideae) seed.

The aim of this study was to describe the anatomy and ontogeny of Pterodon emarginatus seed using the usual techniques. The ovules are campilotropous, crassinucelate, and bitegmic. The following processes occur during integument development: anticlinal divisions and phenolic compound accumulations in the exotesta, whose cells become palisade; predominantly periclinal divisions and cell expansio...
