Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Summary

This summary is machine-generated.

Domestication is redefined as the evolution of a nonhuman population adapting to human-created environments (anthropogenic niches). A domestic population thrives only within these human-influenced niches, offering a new framework for understanding species survival.

Area of Science:

Evolutionary biology
Ecology
Anthropology

Background:

Current definitions of domestication focus on human control and achievement.
Existing definitions struggle to consistently differentiate domestic from non-domestic populations.
Domestication involves diverse human-species interactions beyond simple control.

Purpose of the Study:

To propose a new, observable definition of domestication.
To shift focus from human achievement to species evolution within anthropogenic niches.
To provide a consistent framework for studying human-species evolutionary relationships.

Main Methods:

Conceptual redefinition of domestication based on evolutionary principles.
Focus on the observable relationship between nonhuman populations and anthropogenic niches.
Application of the proposed definition across diverse species (plants, animals, microbes).

Main Results:

A proposed definition: domestication as evolution in response to an anthropogenic niche.
A domestic population is defined by its inability to survive outside an anthropogenic niche.
This definition bypasses the need to identify ancestral populations.

Conclusions:

The proposed definition offers a robust, observable, and consistent framework for domestication studies.
It facilitates investigation into the mechanisms of adaptation to human-influenced environments.
This perspective aids in predicting species' long-term survival in a human-dominated world.
