Ripening and dehiscence of the anther in some Crocus(Iridaceae) species [PDF]

Caryologia, 2000
Abstract The anther development was examined in some Crocus species, by light and scanning electron microscopy. Epidermal cells develop a longitudinal stomium which is connected to the interlocular septum by cells with wide intercellular spaces.Endothecial cells are mono or bilayered, and they develop annular wall thickenings.Middle layer cells ...

A biomechanical model of anther opening reveals the roles of dehydration and secondary thickening.

, 2012
Understanding the processes that underlie pollen release is a prime target for controlling fertility to enable selective breeding and the efficient production of hybrid crops.

Expression of rolB in tobacco flowers affects the coordinated processes of anther dehiscence and style elongation

, 2004
The effect of auxin on stamen and pistil development in tobacco flowers was investigated by means of the localized expression of rolB (root loci B), an Agrobacterium oncogene that increases auxin sensitivity in a cell-autonomous fashion.

Rozwój warstw ściennych i otwieranie się pylnika u kilku dzikich gatunków ziemniaka (Solarium chacoense Bitt., S. phureja Juz. et Buk., 5. giberulosum Juz. et Buk., S. Commersonii Dun.) [The development of the parietal layers and dehiscence of the anthers at some wild potato species (Solanum chacoense Bitt., S. phureja Juz. et Buk., S. giberulosum Juz. et Buk., and S. Commersonii Dun.]

Acta Agrobotanica, 2015
The anthers in these species like in whole genus Solanum are poricidal still some differences have been observed in structure of their anther walls. The fibrous cells associated with dehiscence restricted usually to the area around the pore may form a ...

A RING-type E3 ligase controls anther dehiscence by activating the jasmonate biosynthetic pathway gene DEFECTIVE IN ANTHER DEHISCENCE1 in Arabidopsis

, 2014
Suppression of expression of DAF [DEFECTIVE IN ANTHER DEHISCENCE1 (DAD1)-Activating Factor], a gene that encodes a putative RING-finger E3 ligase protein, causes non-dehiscence of the anthers, alters pollen development and causes sterility in 35S:DAF ...

Whole-transcriptome analysis and construction of an anther development-related ceRNA network in Chinese cabbage (Brassica campestris L. ssp. pekinensis)

Scientific Reports, 2022
Anther development is precisely regulated by a complex gene network, which is of great significance to plant breeding. However, the molecular mechanism of anther development in Chinese cabbage is unclear.

Anther Dehiscence

, 2017
To estimate the pollen presentation schedule in each population, we tracked anther dehiscence in ten male-phase flowers on each day of data collection.

Sequential Pathways of Anther Dehiscence in Sesbania speciosa.

CYTOLOGIA, 1991
The mechanism of anther dehiscence in Sesbania speciosa was followed using light and scanning electron microscopic techniques. The following sequence of events occur (i) Epidermis and endothecium expand, (ii) Branched wall thickenings occur only in the endothecium cells, (iii) Septum cells dissociate, (iv) Tapeta of two adjacent locules lyse due to ...

High-temperature stress suppresses allene oxide cyclase 2 and causes male sterility in cotton by disrupting jasmonic acid signaling

Crop Journal, 2023
Cotton (Gossypium spp.) yield is reduced by stress. In this study, high temperature (HT) suppressed the expression of the jasmonic acid (JA) biosynthesis gene allene oxide cyclase 2 (GhAOC2), reducing JA content and causing male sterility in the cotton ...

Achieving High‐Density and Stress‐Resilient Maize Breeding Via Germplasm Innovation

Advanced Science, EarlyView.
Global population growth and climate change have exacerbated the global food crisis. This perspective presents a conceptual framework focusing on enhancing population advantages. Several novel breeding objectives are proposed to improve density tolerance and stress resistance for yield improvement.
