A Compendium of Plant Species Producing Pollen Tetrads
Flowering plants shed their pollen either as single grains or in groups of two or more grains. Groups of four grains are of particular interest since they are commonly derived from the same meiotic divisions. Retention of meiotically related gametes in a group enables the use of a powerful genetic tool—tetrad analysis. While tetrad analysis is a routine tool in yeast (and other fungal systems) ...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولPollen tetrads in the detection of environmental mutagenesis.
Although pollen viability promises to be a very sensitive indicator of environmental mutagenesis, its utility in this regard is confounded by the fact that it is influenced also by nonmutagenic environmental stress. However, with appropriately homozygous material, we may discriminate between mutagenic and nonmutagenic influences on pollen viability. Pollen inviability resulting from mutagenesis...
متن کاملDNA densitometry of colorectal cancer.
DNA analysis was assessed by densitometry for 281 cases of colorectal adenocarcinoma. Detection of aneuploidy in a single case rose from 65% if one, to 92.5% when three or more sections, were analysed. Although aneuploid tumours had significantly larger nuclear areas than near diploid tumours (p = 0.009), densitometric measurements showed no association with clinicopathological variables. DNA c...
متن کاملClinical Use of Bone Densitometry
densitometry devices. Many studies have shown a strong relationship between bone density at virtually any skeletal site and the subsequent risk for fractures of the spine, hip, and forearm.1 The exact strength of this relationship depends on the type of fracture and the skeletal site measured. In most cases, the relationship between bone density and fracture by analogy is as strong or stronger ...
