Elucidating the mechanism of poricidal anther dehiscence in Miconia species (Melastomataceae)

open access: yesFlora: Morphology, Distribution, Functional Ecology of Plants, 2014
Abstract Melastomataceae have porate anthers. However, unlike Solanaceae and many monocots, in which the poricidal dehiscence depends on the presence of a mechanical layer (often the endothecium), most members of Melastomataceae have no evident specialized layer related to the poricidal opening.

A GARP transcription factor anther dehiscence defected 1 (OsADD1) regulates rice anther dehiscence

Plant Molecular Biology, 2019
Anther dehiscence, one of the essential steps in pollination and double fertilization, is regulated by a complex signaling pathway encompassing hormones and environmental factors. However, key components underlying the signaling pathway that regulate anther dehiscence remain largely elusive. Here, we isolated a rice mutant anther dehiscence defected 1 (

THE ROLE OF INVERTASES IN ANTHER DEHISCENCE [PDF]

open access: yes, 2023
The opening of anthers to release pollen (anther dehiscence) is a complex, regulated process. One of the mechanisms contributing to anther dehiscence is the active removal of water from anthers. Invertases are plant enzymes which cleave sucrose into glucose and fructose, changing the osmotic potential, suggesting they may have a role in water movement ...

The diversity of anther structures and dehiscence patterns among Hamamelididae

Botanical Journal of the Linnean Society, 1989
HUFFORD, L. D. & ENDRKSS, P. K., 1989. The diversity of anther structures and dehiscence patterns among Hamamelididae. This survey of anther structures and dehiscence patterns focuses on the range of diversity among extant Hamamelididae. The definition and structure of the anther stomium are considered in detail to provide a basis for characterizing ...

Auxin controls Arabidopsis anther dehiscence by regulating endothecium lignification and jasmonic acid biosynthesis

open access: yesPlant Journal, 2013
It has been suggested that, in Arabidopsis, auxin controls the timing of anther dehiscence, possibly by preventing premature endothecium lignification. We show here that auxin content in anthers peaks before the beginning of dehiscence and decreases when

Activation tagging of an Arabidopsis SHI-RELATED SEQUENCE gene produces abnormal anther dehiscence and floral development

open access: yesPlant Molecular Biology, 2010
The tapetum is a layer of cells covering the inner surface of pollen sac wall. It contributes to anther development by providing enzymes and materials for pollen coat biosynthesis and nutrients for pollen development.

Characterising the regulatory network of MYB26 during anther dehiscence [PDF]

open access: yes, 2017
Pollen development and release involves a number of important stages, which govern the success of fertilisation and thus indirectly crop yields. The secondary cell wall in the anther plays a pivotal role in anther dehiscence by offering mechanical strength required for opening and pollen release (Wilson et al. 2011). MYB26/MALE STERILE35(MS35) is a key
