Pre-meiotic anther development

2019
Most genetic and molecular analyses of anther development utilize Arabidopsis thaliana, Oryza sativa (rice), and Zea mays (maize). Especially in maize, early stages of anther development are easy to study because: (1) Maize has unisex flowers. (2) Compared to rice or A.

RESPIRATION OF DEVELOPING ANTHERS

Nature, 1947
UNDER greenhouse conditions the growth in length of flower buds of Lilium longiflorum is exponential over the period of about five weeks preceding anthesis, during which they elongate from about 10 mm. to about 155 mm. Blackman's1 formula can be fitted satisfactorily to the growth curves, if length is substituted for weight (Lt = Loert).

Anther development inXylopia nigricans

Proceedings / Indian Academy of Sciences, 1988
In the anther primordium ofXylopia nigricans, the archesporium differentiates discontinuously with intervening sterile tissue. Each archesporial cell divides periclinally and develops into a micro-sporangium with a single microspore mother cell. Thus the anther becomes multisporangiate. The tapetal cells are uninucleate.

Comparative development of aseptate and septate anthers of Annonaceae

American Journal of Botany, 2003
We compared anther development in 13 genera and 15 species of Annonaceae to document the nature and development of anther septa. In aseptate anthers, all sporogenous initials proceed to sporogenesis and meiosis. In septate anthers, a small number of sporogenous initials, in a discontinuous distribution pattern, differentiate into sporogenous cells; the

TRANSFER OF DEVELOPING BEAN POLLEN IN LILY ANTHERS

Acta Botanica Neerlandica, 1982
SUMMARY Developing fertile and sterile microspores and pollen of Vicia faba L. are injected into lily anthers during different stages of their development. Changes in autofluorescence of bean microspore or pollen wall are observed and recorded after about 65 hours of incubation.

Pollen and anther development in Nelumbo (Nelumbonaceae)

American Journal of Botany, 1999
The Nelumbonaceae are a small family of aquatic angiosperms comprising Nelumbo nucifera and Nelumbo lutea. Historically, the genus has been considered to be closely related to Nymphaeales, however new systematic work has allied Nelumbo with lower eudicots, particularly Platanus. In recent years, studies of pollen development have contributed greatly to

Anther Development Dissected

Science, 2011
Development![Figure][1] CREDIT: [THINKSTOCK.COM][2] Anthers are the male reproductive organ of flowering plants. Unlike in animals, they originate from somatic tissue, of which a small subset of cells undergoes meiosis and develops into pollen. Kelliher and Walbot used confocal microscopy to dissect the developmental stages of the maize anther ...

Transcriptional regulation of anther development in Arabidopsis

Gene, 2019
This review focuses on the current knowledge of transcription factors involved in Arabidopsis anther development. Anther development is a multistage process and controlled by a complex network of transcription factors acting in spatio/temporal manner.

Identification of anther-specific/predominant genes regulated by gibberellin during development of lily anthers

Journal of Plant Physiology, 2008
We successfully identify anther-specific/predominant genes induced by gibberellin (GA) at the microspore stage of lily (Lilium longiflorum) anthers. We used a suppression-subtractive hybridization strategy to identify 22 individual cDNAs followed by a reverse RNA dot plot to determine their specificities at the microspore stage. Of the 22 genes, 12 are

Cytological analysis and genetic control of rice anther development

Journal of Genetics and Genomics, 2011
Microsporogenesis and male gametogenesis are essential for the alternating life cycle of flowering plants between diploid sporophyte and haploid gametophyte generations. Rice (Oryza sativa) is the world's major staple food, and manipulation of pollen fertility is particularly important for the demands to increase rice grain yield.
