Plant evolution is the subset of evolutionary phenomena that concern plants. Evolutionary phenomena are characteristics of populations that are described by averages, medians, distributions, and other statistical methods. This distinguishes plant evolution from plant development, a branch of developmental biology which concerns the changes that ...
Plant genetics – study of heredity and variation in plants; Plant pathology – study of plant diseases; Plant physiology – subdiscipline of botany concerned with the functioning, or physiology, of plants. [1] Cell biology – study of the cell as a complete unit, and the molecular and chemical interactions that occur within a living cell.
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 branch of genetics that employs methods and techniques of [[Glossary of genetics (M–Z)molecular biology#{{{1}}}| {{{1}}}]] to study the structure and function of genes and gene products at the molecular level. Contrast classical genetics. monophyly morphological species concept mosaic evolution
In biology, evolution is change in the heritable characteristics of biological organisms over generations due to natural selection, mutation, gene flow, and genetic drift. Also known as descent with modification .
In this sense it is plant evolutionary developmental biology (plant evo-devo). According to Zimmermann, diversity in plant evolution occurs though various developmental processes. Three very basic processes are heterochrony (changes in the timing of developmental processes), heterotopy (changes in the relative positioning of processes), and ...
It combines ecology, evolution, and genetics to understand the processes behind adaptation. [1] It is virtually synonymous with the field of molecular ecology . This contrasts with classical genetics , which works mostly on crosses between laboratory strains, and DNA sequence analysis , which studies genes at the molecular level.
The idea of evolution by natural selection was proposed by Charles Darwin in 1859, but evolutionary biology, as an academic discipline in its own right, emerged during the period of the modern synthesis in the 1930s and 1940s. [8] It was not until the 1980s that many universities had departments of evolutionary biology.
