The Wild Ones

The Wild Ones was founded by naturalist and teacher Lorrie Otto. She planted blue and white aster Aster azureus), yellow goldenrod (Solidago... 

The Wild Ones website (http //www.for-wild.org/) is a link-filled clearinghouse with questions and answers on practical problems facing ecological restoration advocates, as well as connections to conferences, local chapters and events. 

In human medicine, selection pressure is at its most intense in hospitals, where antibiotics are extensively used. The major cause of problems of antimicrobial resistance in humans arises from overuse of antimicrobials at therapeutic levels in humans. It is generally accepted that drug resistance that develops in a bacterium as a result of mutation is only of importance within the individual host and a single bacterial strain. Because the determinant is chromosomal, the resistance cannot be transferred between different bacterial species and genera. In addition, the mutationally resistant microorganism is not usually as viable as the wild ones hence once the selective antibiotic is removed from the environment, the proportions of the mutant decrease. If exposure to the antibiotic continues, however, the mutants can become life-threatening to the patient. It should be understood that the antibiotic does not induce the mutation. The mutant simply takes advantage of its fortuitous spontaneous appearance to flourish in the presence of a selected antibiotic. 

The main difference between wild game and domestic animals and birds is that the wild ones are leaner and stronger flavored than a stall-fed ox or a caged bird—they have developed strong muscles from exercising. For this reason, the meat needs a blanket of fat before it is cooked—lard, fat bacon, or salt pork and it may require tenderizing. 

The problems with jojoba as a commercial crop are the usual ones of domestication and cultivation. It is a slow-growing plant, available only in the wild and therefore has very wide genetic variabiUty. Efforts are underway to select the most promising variants and cultivate these as a crop in the southwestern United States deserts (7). A possible alternative for producing jojoba oil is to culture plant embryos in bioreactors (see Cell culture technology). 

One of the most important molecular functions of p53 is therefore to act as an activator of p21 transcription. The wild-type protein binds to specific DNA sequences, whereas tumor-derived p53 mutants are defective in sequence-specific DNA binding and consequently cannot activate the transcription of p5 3-con trolled genes. As we will see more than half of the over one thousand different mutations found in p53 involve amino acids which are directly or indirectly associated with DNA binding. 

Model building also predicts that the Ala 216 mutant would displace a water molecule at the bottom of the specificity pocket that in the wild type enzyme binds to the NH3 group of the substrate Lys side chain (Figure 11.12). The extra CH3 group of this mutant is not expected to disturb the binding of the Arg side chain. One would therefore expect that the Km for Lys...

The literature is less extensive on the use of protoplasts in stress-tolerance investigations however, some applications have been attempted. For example, in one study protoplasts were isolated from the leaves of a wild relative of tomato shown to be salt tolerant and from a salt-sensitive, cultivated species (Rosen Tal, 1981). In the presence of NaCI the plating efficiency (number of surviving cells/number of cells applied to the plate) of the wild relative was greater than the cultivated, sensitive cultivar. Proline, when added to the culture media, was found to enhance the plating efficiency of the salt-sensitive cultivar but not the wild, salt-tolerant relative. These results suggest that traits related to salt tolerance are expressed by the isolated protoplasts and that the response of protoplasts to environmental stress can be manipulated, i.e. the proline response. 

Many of these tests gave evidence for changes in behavior following exposure to neurotoxic pesticides. The author concludes that significant behavioral effects were often recorded down to one order of magnitude below the LCjo in question. Some tests, such as operant tests, were relatively simple and gave reproducible results, but it was difficult to evaluate the relevance of these to survival in the wild. Other tests, such as breeding behavior and prey capture, were more complex and less reproducible, but more relevant to the natural world.
