Our objective is to gain a better understanding of the molecular basis of response to selection for grain methionine concentration.
These experimental populations explore both the potential for local adaptation (Allard et al. 1972) and the genetic basis of response to selection (Clegg et al. 1972; Weir et al. 1972).
Because water is becoming limited for agriculture in many areas of the world, the investigation of natural mechanisms of drought tolerance is an important strategy for understanding the biological basis of response to drought stress and for selection of plants with improved drought tolerance [ 1, 2].
In this case, dose selection based on biomarkers probably had been superior to dose selection on the basis of response rates.
This experiment was conducted to assess the efficiency of selection on the basis of response to artificial challenges in order to breed sheep resistant to natural infection.
However, the similarities and differences in the genetic basis of responses to artificial vs. natural selection are an interesting topic in particular, for the interpretation of the large amount of genetic data available from breeding programs (Stern and Orgogozo 2009)—that should be addressed in future studies.
2. Sensitizers, following their increase in responsiveness from trial 1 to trial 2 (which was the basis of their selection), show a dramatic decrease in response magnitude from trial 2 to trial 3 in all four effector systems.
We hypothesised that tumours containing regions of hypoxia and anoxia would give rise to CTCs that, on the basis of their selection by hypoxia, should be more aggressive than non-CTCs, and would show an altered response to hypoxia.
On the basis of this selection procedure, face-to face interviews were carried out on 2152 respondents (of which 2149 were complete), giving a response rate of 74.2%.
Therefore, the investigation of molecular mechanisms into heat-tolerant head-forming capacity in broccoli can help decipher the biological basis of the response to heat and the selection of broccoli with improved heat tolerance.
