Flower senescence in this context will happen when it becomes more advantageous for the plant to construct a new flower - including renewed odds of getting pollinated - than to maintain an existing one. Flower senescence can therefore be defined as the events that lead to the death of flower...
Developmental control and biotechnology of floral pigmentation
Essay - 7 pages - Biology
For many angiosperms, pigment formation is a key part of flower development. At least 200 plant genera contain species that show color change during flower development. Thus, variation in flower color associated with a change in nectar and pollen availability may be a common occurrence. The...
Regulation of floral organ-identity gene expression
Essay - 5 pages - Biology
A key advance in the field of flower development has been the uncovering of a direct role for the FM-identity gene LEAFY (LFY) in activation of the floral organ-identity genes. LFY encodes a novel plant-specific DNA-binding protein that can bind in vitro to the promoters of several floral...
Molecular biology of floral organogenesis
Essay - 4 pages - Biology
In the early 1990s, genetic studies on Arabidopsis thaliana and Antirrhinum majus led to the isolation and characterization of floral organ-identity genes (also called floral homeotic genes) and the establishment of the seminal ABC model for flower development. This model proposed that different...

The molecular biology of apomixis
Essay - 6 pages - Biology
Apomixis is the subject of a number of recent reviews. Some authors have focused on the potential agronomic and economic benefits of apomixes. Others have discussed the developmental and genetic basis of apomixes or reviewed current theory regarding the evolutionary and ecological implications of...
Flower origin
Essay - 4 pages - Biology
Since the identity of floral organs is specified by conserved floral organ-identity genes, clarifying the phylogeny of these genes and their protein products may provide us with valuable insights into the evolution of flowers. Analysis of numerous MADS box genes from mosses and ferns suggested...
Physiology of Photoperiodism
Essay - 5 pages - Biology
Photoperiodism can be defined as the response to changes in day length that enables plants (or any other living organism) to adapt to seasonal changes in their environment. Except at the equator, the passage of the year is marked by a continuous but highly reproducible variation in the length of...
Genes regulating ovule development
Essay - 5 pages - Biology
Ovules are the precursors of seeds. More specifically, they are sporophyticstructures and the site of megagametogenesis or female gamete shape that culminates in the formation of the haploid embryo sac. The prototypical angiosperm ovule consists of three parts: (1) the nucellus, where...
Understanding children with Asperger's Syndrome through visual art
Essay - 5 pages - Medical studies
It is believed by many that art is one of the most basic ways that people communicate their inner feelings, thoughts and values with the world outside themselves. This is particularly true of children, who are often times painfully honest in expressing how they see themselves and others by...
Genetic engineering of plant cells
Essay - 5 pages - Biology
In this text, we shall see how selection data have been used to assist the design of experiments on the modification of plants using recombinant DNA (genetic engineering). It is evident that in some situations the potential of in vitro selection is limited by a number of difficulties. It is...
