Anther Ontogeny and Microsporogenesis in <i>Helianthus annuus</i> L. (Compositae)
In this study, anther ontogeny and microsporogenesis were analysed in Helianthus annuus L. The undifferentiated anther is ovoid-shaped and the differentiation starts with the appearance of archesporial cells. Mature anthers are tetrasporangiate.

The True Identity of the “Second Pollen Morphology” of Camellia oleifera—Stomium Cells
Previous studies on Camellia oleifera pollen morphology have indicated dual morphologies, defined as “dimorphism”. However, they were limited to morphological studies at the end of final development and did not elucidate the origin, structure, and ...

The changes in pollen grain diameter were examined in relation to the floret opening and anther dehiscence in rice (Oryza sativa L.). In the first experiment, the florets were artificially opened by excising the top of the glumes at various times before ...

An Arabidopsis flavonoid transporter is required for anther dehiscence and pollen development [PDF]
FLOWER FLAVONOID TRANSPORTER (FFT) encodes a multidrug and toxin efflux family transporter in Arabidopsis thaliana. FFT (AtDTX35) is highly transcribed in floral tissues, the transcript being localized to epidermal guard cells, including those of the anthers, stigma, siliques and nectaries.

The Mechanics of the Grass Flower: Anther Dehiscence and Pollen Shedding in Maize [PDF]
Abstract In this paper on the flower mechanics of the grasses, the opening mechanism of the maize anther is studied. Both the septum between each two locules and the stomium of these porate-dehiscing anthers appear to be opened due to lysis of the middle lamellae of their cells.

A Novel Cell Ablation Strategy Blocks Tobacco Anther Dehiscence [PDF]
We utilized a new cell ablation strategy to ablate specific anther cell types involved in the dehiscence process. The tobacco TA56 gene promoter is active within the circular cell cluster, stomium, and connective regions of the anther at different developmental stages.

The role of atmospheric precipitation in anther dehiscence [PDF]
Anther dehiscence is an important process taking place at the end of the plant life cycle. This process consists of various follow-up steps which result in anther opening and pollen grains exposure.
