Using proteomics to analyze phosphorylation, acetylation, and other posttranslational modifications has been a very important method in biological research. Here we take the rice meiotic anther as an example to introduce the experimentally verified proteomic analysis methods of plant tissue-specific phosphorylation and acetylation, including total ...

The phylogeny of land plants: A cladistic analysis based on male gametogenesis
Plant Systematics and Evolution, 1994A cladistic analysis was carried out to resolve phylogenetic pattern among bryophytes and other land plants. The analysis used 22 taxa of land plants and 90 characters relating to male gametogenesis.Coleochaete orChara/Nitella were the outgroups in various analyses using HENNIG86, PAUP, and MacClade, and the land plant phylogeny was unchanged ...

Molecular analysis of male gametogenesis in plants
Trends in Genetics, 1991Reproduction in plants rivals the complexity of the process in animals. Recently, several genes that are expressed at specific stages during male gametogenesis have been cloned. These anther-specific genes are providing tools with which to study the cis- and trans-acting factors that regulate gene expression during pollen formation.

Male gametogenesis and germline specification in flowering plants
Sexual Plant Reproduction, 2010During angiosperm male gametophyte development, the male germline is segregated by an asymmetric cell division of the haploid microspore. This review encompasses recent advances in understanding the genetic and molecular mechanisms involved in generating the male germline from this pluripotent germline initial and in specifying the production of the ...

Gamete orientation and induction of gametogenesis by pheromones in algae and plants
Plant, Cell & Environment, 1993ABSTRACTThis review attempts to give a concise overview of the widespread occurrence and the significance, structure and function of pheromones in the chemical communication between individuals of the same species during sexual reproduction in algae and plants.

Euphytica, 1975
A research has been carried out on the occurrence of 2n gametes in Brassica oleracea and on their possible way of origination. After microsporogenesis it appeared that unreduced PMC's, dyads and triads occurred. Giant pollen grains with two (diploid) and four (haploid) generative nuclei, respectively, were found, resulting from a deviating cytokinesis ...

Polarity during sporogenesis and gametogenesis in plants
2004In this article the importance of polarity during sporogenesis and gametogenesis in plants is discussed. Polarity is one of the important] processes during cell differentiation. Many studies have been done about this subject but it does not become clear how or why polarity is taken place during cell differentiation.

Development, 1999
Abstract The relationship between developmental events and the cell cycle was examined in sperm of Arabidopsis thaliana. Sperm of Arabidopsis rapidly enter the S (synthesis) phase of the cell cycle after inception from mitosis of the generative cell.

1997
The use of heterochromatic regions, containing moderately repetitive DNA as markers, has allowed to follow the course of development of the generative and vegetative nuclei in the pollen grains of some species of Tradescantia and Narcissus. It has been found that the chromocentres, relatives to the NOR-heterochromatin, are not randomly distributed ...
