Anther development, microsporogenesis and microgametogenesis in Heliconia (Heliconiaceae, Zingiberales)

open access: yesFlora: Morphology, Distribution, Functional Ecology of Plants, 2007
Abstract Anther development, microsporogenesis and microgametogenesis in several species of Heliconia were investigated as part of a complementary embryological study of the Heliconiaceae. All studied Heliconia species present bithecate and tetrasporangiate anthers with fertile pollen grains; only H.

Ultrastructure of microsporogenesis and microgametogenesis in Campsis radicans (L.) Seem. (Bignoniaceae)

open access: yesPlant Systematics and Evolution, 2013
In the present study, microsporogenesis, microgametogenesis and pollen wall ontogeny in Campsis radicans (L.) Seem. were studied from sporogenous cell stage to mature pollen using transmission electron microscopy. To observe the ultrastructural changes that occur in sporogenous cells, microspores and pollen through progressive developmental stages ...

High voltage electron microscopy on microgametogenesis of Haemoproteus columbae

Cell and Tissue Research, 1974
The microgametogenesis of Haemoproteus columbae was investigated by high voltage and conventional electron microscopy and the results were compared. The features of microgametogenesis which have become clear by high voltage electron microscopy include the distribution and arrangement of axonemes in the microgametocyte and the budding process and ...

Ultrastructure of microsporogenesis and microgametogenesis in Brachypodium distachyon

Protoplasma, 2015
Brachypodium distachyon has emerged as a model system for forage grass and cereal grain species. Here, we report B. distachyon pollen development at the ultrastructural level. The process of microsporogenesis and microgametogenesis in B. distachyon follows the typical angiosperm pollen development sequence.
