Domesticated crops

And as we shall see, the demands of turfgrasses are an immediate and profound influence on homeowners, which set people about tasks that keep them busy throughout the growing season. Given the labor performed by people for other domesticated crop species, as Denis Wood has asked regarding cereal grains-especially maize, which cannot reproduce on its own without its human servants- who s to say which species has domesticated which ... 

The National Academy of Sciences Institute of Medicine Concluded that biotech crops pose risks similar to other domesticated crops... 

This example, as well as others (Ellstrand 2003) demonstrate that gene flow between wild and domesticated species can occur but so far has only created problems for the domesticated crop, not for the environment. 

Hybridization The production of offspring (hybrids) from genetically unlike parents, by natural processes or by human intervention (i.e., artificial selection). In plant breeding, includes the process of cross-breeding two different varieties to produce hybrid plants. If the hybrid is more fit than either parent the condition is called hybrid vigor (or heterosis). Hybrid offspring may result from gene flow between domesticated crops and wild relatives. 

Suspension cell cultures have been derived from a number of different plant species, including the widely-used laboratory model Arabidopsis thaliana [15], plants such as Catharanthus roseus and Taxus cus-pidata which are used to produce valuable secondary metaboHtes [16, 17], and important domestic crops such as tobacco, rice, alfalfa, tomato, and soybean [18-22]. Because cell lines from domestic crop species are well-characterized, they have been the most frequently used for recombinant protein production. The most popular cell hnes include those derived from the tobacco cultivars Bright Yellow 2 (BY-2) (Fig. 9.1) and Nicotiana tabacum 1 (NT-1) [2].

In recent years, research attention has turned to evaluating the potential of nontraditional fats/oils sources, including newly domesticated crops, forest oilseeds, bacteria, yeasts and molds, and algae. The reader should consult the references for types of fatty acids and their occurrence in these sources. " ... 

Maize or com (Zea mays) has a long history as a domesticated crop. Today com is the most widely grown cereal crop in the world. In 2008, world com production was 826.3 million tonnes (USDA-FAS, 2008). It is estimated the grain yield will reach 1.2 tonnes/ha...

As noted in Chapter Introduction to Industrial Oil Crops, there are hundreds of plants that produce seed oils containing fatty acids with unusual functionalities. While there are a number of domesticated crops that are used primarily for industrial applications, many of the crops identified were not well-suited to cultivation and required breeding and selection in order to be cultivated as crops (White et al., 1971). Among those crops identified as having value as... 

J. is native to Mexico, Arizona, and California. It is a typical example for a recently domesticated crop where the interest in the chemical composition of the oil was the main driving force for cultivation. There are, however, reports about early applications of j. oil by native Mexican people. The name is of Indian origin and is pronounced ho-ho -ba.
