Microsporogenesis and Embryogenesis in Quercus [PDF]
Botanical Gazette, 1964 Representative species from two subgenera in the genus Quercus were examined for floral structure and phenology, microsporogenesis, and embryogenesis. The species selected for investigation were: Quercus alba in the Lepidobalanus subgenera, and Quercus coccinea and Quercus ilicifolia from the Erythrobalanus group.

Disturbances in microsporogenesis and pollen grain development in Gagea lutea (L.) Ker. Gaw.
Acta Agrobotanica, 2012 The meiotic division of microsporocytes and pollen grain development in Gagea lutea (L.) Ker.-Gaw. (Liliaceae) with fluorescence microscope (excitation light 400 nm) was observed after squashing the anthers in DAPI solution (fluorochrom dying DNA). Up to

Chondriokinesis during microsporogenesis in plants [PDF]
Planta, 2017 Chondriokinesis represents a highly orchestrated process of organelle rearrangement in all dividing plant and animal cells, ensuring a proper course of karyokinesis and cytokinesis. This process plays a key role in male gametophyte formation. Chondriokinesis is a regular rearrangement of cell organelles, assuring their regular inheritance, during both ...

Pollen development in Mill. (Annonaceae). Implications for the evolution of aggregated pollen [PDF]
, 2009 In most flowering plants, pollen is dispersed as monads. However, aggregated pollen shedding in groups of four or more pollen grains has arisen independently several times during angiosperm evolution.
