1. Plant morphology (especially flowers)
2. Plant compounds
3. Plant genes
Study of plant diversification, and the processes by which this diversification
A sub-set of systematics,
The Science of Classification
Purpose of classification
Groups of different kinds of organisms that reflect similarities between them and
their evolutionary relationships.
Identify patterns of plant use, and management.
Some common phyla
Plant breeding applies the principles of plant genetics to produce new and unique
plant material for human use.
The science of altering the genetic pattern of plants in order to increase their value.
Plant Breeding has three phases:
Evolution of Phenotypic and Genetic Traits during Domestication
Six key phenotypic traits in domestication:
Elimination/reduction of natural seed dispersal
Reduction in seed dispersal aids
Trends towards increasing seed/fruit size
Domestication of Cultivated Plants
Ethnobotany = study of the relationships between people and plant
Paleobotany = paleontology + biology; the recovery and identification of ancient plant remains
Ecology of Managed Plant Systems
Definitions and terms
This course takes an ecological view of people and their plants.
Ecology is the branch of biology that deals with the relationships among organisms and their physical
Plant Centers of Origin
The Center of Origin is the geographical region from which a species originated
This might include the original species, related genera, and wild ancestors.
This likely also includes host diseases and insect pests.
A basic understanding of plant genetics is necessary to understand:
a) the basis for plant variation
b) the basis for plant breeding
c) the basis for bioengineering
DNA (deoxyribonucleic acid)
DNA is a series of nucleic acids: guanine (G),
