Genotype analysis

There can be little doubt that certain stresses have characteristic demographic consequences both for populations and for plant parts and it is also evident that, according to taxonomic and evolutionary history, species and genotypes may differ in their responses to the same stress. Thus, demographic study is often a useful preliminary to analysis of the causation and evolutionary origins of particular stress responses. However, some demographers go further and advocate long-term field observation as the only reliable way forward ... 

The ultimate goal of microarray-based expression analysis is to acquire a comprehension of the entire cellular process, in order to exploit and to standardize the multidi-menisional relations between genotype and phenotype. However, an increasingly important parameter, which has not yet been substantially taken into account, is the role of cellular translation. This means that mRNA expression data need to be correlated with the assortment of proteins actually present in the cell. One approach is based on the use of microarrays containing double-stranded DNA probes for the analysis of DNA-protein interaction and, thus, the detection and identification of DNA-binding proteins by means of fluorescence [130] or mass spectrometry analysis [131]. Moreover, substantial efforts are currently under way to develop protein, antibody, or even cell arrays, applicable to the cor-...

Analysis in diverse lines can facilitate identification of useful alleles that control expression of enzymes upstream of the carotenoid pathway, a feature that would not be evident from conventional end-product screening of breeding lines. Moreover, this characterization sets the stage for marker-assisted selection of superior endogenous alleles and facilitates selection of introduced transgenes that may be necessary to supplement the genotypic contribution required for a particular plant chemical outcome. 

Two additional pharmacogenetic studies utilized the Los Angeles Mexican American study sample previously cited (Mendoza etal, 2001). First, Luo etal. (2005) extended the CYP2D6 genotyping analysis further to include 6, 7, 8,...

The microarray consists of small DNA fragments, chemically synthesized at specific locations on a coated quartz surface. The number of locations on one array is in the range of millions. DNA is extracted and labeled from experimental samples, and then samples are hybridized on the array. Labels are monitored so that gene- and exon-level expression analysis, novel transcript discovery, genotyping, and resequencing can be carried out. 

Finally, note that eukaryote chemotypes have as a general feature the increase inside the cell vesicles of elements, here calcium, previously confined to the outside of prokaryotes, but these increases are different in different vesicles and organelles and in different organisms separating cells into different chemotypes. This is also seen in their minerals. There is as yet far too little quantitative analysis of calcium or indeed of elements generally to allow us to build a full picture of chemotypes together with genotypes (see Table 8.22).
