Development of capitate glands on the leaves of annual wormwood (Artemisia annua L.) was monitored with scanning and transmission electron microscopy. Differentiation of foliar cells into gland cells began in the youngest leaf primordia. After differentiation into a 10-celled biseriate structure of two stalk cells, two basal cells, and three pairs of secretory cells, the cuticle of the six secretory cells separated from the cell walls to form a bilobed sac that eventually splits to release its… 

Gland Development on Leaf Surfaces of Nepeta racemosa

Mature peltate glands exhibited a distended cuticle and large subcuticular cavity, presumably containing the essential oils, and four major stages in the development of the peltates secretory cells were identified.

Floral morphology of Artemisia annua L. was described using light and scanning electron microscopy. Floral trichomes include nonglandular T-shaped filamentous trichomes, which occur on the basal

Development and some histochemical aspects of foliar glandular trichomes of Stevia rebaudiana (Bert.) Bert. - Asteraceae

Basic histochemical tests reveal that the glandular trichomes of Stevia rebaudiana (Bert.) Bert.-Asteraceae are lipophilic (mainly) and hydrophilic in nature.

Development and ultrastructure of glandular trichomes inpelargonium x fragrans ‘mabel grey’ (geraniaceae)

The glandular trichomes of leaves from Pelargonium xfragrans ‘Mabel Grey’ (Geraniaceae) were examined by light, scanning, and transmission electron microscopy and the implication of structural differentiation in these trichome cells is discussed.

Glandular trichomes of the flowers and leaves in Millingtonia hortensis (Bignoniaceae)

Three types of the glandular trichomes are developed on the flowers and leaves of Millingtonia hortensis. Morphology, cell ultrastructure and content of the volatile compounds are specific to each

Ultrastructure of glandular hairs of Sigesbeckia jorullensis Kunth (Asteraceae)

Multicellular long-stalked glandular hairs of the outer involucral bracts of Sigesbeckia jorullensis Kunth were investigated with transmission electron micros-copy and light microscopy demonstrated that there was a subcuticular space formed exclusively by a thin cuticle in the secretory phase.

It is concluded that synthesis and accumulation of phenolic substances and terpenoids takes place in the clavate glandular trichome on Empetrum nigrum leaves.

Histochemical tests reveal the lipophilic character of the secreted material corresponding probably to terpenoids, and modifications of plastids morphology and increase of ER profiles must be related to secretion.

The glandular trichomes of Artemisia campestris (ssp. maritima) originate from a single protodermal cell and develop through an anticlinal and several periclinal divisions; thus, gland density decreases with leaf development.

During the course of evolution, secretory tissues seem to have developed from secretory idioblasts scattered among the cells of the ordinary tissues, such as ducts and cavities developed and finally secretory trichomes.

Glandular trichomes on the inflorescence of Chrysanthemum morifolium cv. Dramatic (Compositae). I. Development and morphology

Glandular trichomes in both positions are initiated by the enlargement of single epidermal cells followed by a single anticlinal division and a series of periclinal divisions resulting in a 10-celled biseriate structure.

It is hypothesize that the gene responsible for the lack of secreting capability interrupted normal chloroplast development and that chloroplasts in N. tabacum trichomes are necessary for the synthesis of certain exudate compounds.
