A total of 1918 loci, detected by the hybridization of 938 expressed sequence tag unigenes (ESTs) from 26 Triticeae cDNA libraries, were mapped to wheat (Triticum aestivum L.) homoeologous group 4 chromosomes using a set of deletion, ditelosomic, and nulli-tetrasomic lines. The 1918 EST loci were not distributed uniformly among the three group 4 chromosomes; 41, 28, and 31% mapped to chromosome...
Comparative studies of terrestrial vertebrates are one approach that can be used by researchers to build on the extensive work done by animal ecologists and applied ecologists in cities (Luniak, 1990; VanDruff et al., 1994; Nilon and Pais, 1997).
