An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
A key event in the conservation of plant genetic resources was the establishment of the International Board for Plant Genetic Resources (IBPGR) (now Bioversity International) in 1974, whose mandate was to promote and assist in the worldwide effort to collect and conserve the plant germplasm needed for future research and production. IBPGR ...
Phytogeography (from Greek φυτόν, phytón = "plant" and γεωγραφία, geographía = "geography" meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. [1]
Statistical tools such as the Mantel test or partial Mantel test are commonly used to correlate genetic patterns with landscape features. Linear regression models and ordination techniques are also common. [2] Geographic information systems (GIS) can be used to visualize genetic patterns across space by plotting genetic data on a map of the ...
Differences between plant and animal physiology and reproduction cause minor differences in how they evolve. One major difference is the totipotent nature of plant cells, allowing them to reproduce asexually much more easily than most animals. They are also capable of polyploidy – where more than two chromosome sets are inherited from the ...
Vavilov's 1924 scheme suggested that plants were domesticated in China, Hindustan, Central Asia, Asia Minor, Mediterranean, Abyssinia, Central and South America A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties.

Biogeography is a synthetic science, related to geography, biology, soil science, geology, climatology, ecology and evolution. Some fundamental concepts in biogeography include: allopatric speciation – the splitting of a species by evolution of geographically isolated populations; evolution – change in genetic composition of a population
Plants act in similar ways as they can also use water currents, winds, or moving animals to transport their gametes. Seeds, spores, and fruits can have certain adaptations that aid in facilitation of movement. [11] Active Dispersal (Density-Dependent Dispersal) In active dispersal, an organism will move locations by its own inherit capabilities.
