Genetic variation in root hair length and density in maize is controlled by several major QTLs (Zhu et al., 2005 b ), suggesting that this trait could be selected in breeding programmes through marker-assisted selection.
If these branch-falls were prevalent enough of a selective force, species intolerant of this damage could be selected against in areas of high branch-fall.
On the other hand, if a critical pathway is the target, then chemical compounds that interfere in this pathway could be selected.
As the group of 31 experts contained only experts with internet and computer experience at the intermediate and expert levels, only eight experts from this group could be selected to participate in our study.
From this array COs could be selected that were able to hybridise specifically to labelled PCR products from the ITS region of Fusarium graminearum/Fusarium culmorum, Fusarium pseudograminearum, Fusarium poae, Fusarium sporotrichioides, Fusarium equiseti, Fusarium langsethiae and Fusarium tricinctum/Fusarium avenaceum.
Because neither British man has achieved the 'A' standard of 8.25m this season, only one could be selected.
To generate the high light tolerant mutants, no strong mutagen (or no mutagen at all) was used because in this case the phenotype could be selected for.
As discussed by Boeck et al (2006), this absolute threshold value could be selected only by conducting a prospective clinical trial that prospectively defines it (e.g. selecting an absolute CA 19-9 threshofd of 1000 U ml 1 for patients with metastatic disease).
This way, the healthiest cells could be selected to secrete all of the chemicals normally released by endothelial cells and placed in multiple locations in the body to control disease.
In this way statistically different features could be selected and subsequently identified as compounds.
