A cytogenetic and molecular characterization of Meloidogyne-induced giant cell nuclei
(1990)
DNA content of Meloidogyne-induced giant cell nuclei in several host species was measured microspectrophotometrically. Nuclei from mature giant cells in pea and tomato averaged over a 14-fold increase in DNA compared to ...
Genotypic competition models in loblolly pine progeny tests
(1990)
Three areas pertinent to the understanding of genetic competition were discussed in this study: 1) static competition models: 2) dynamic competition models: and 3) growth and yield models with genetic competition. Based ...
Studies on genetic parameters of agronomic, grain structure, and malting characteristics of sorghum (Sorghum bicolor (L.) Moench)
(1990)
This study had two distinct components: an agronomic/breeding segment and a sorghum malt component. The first consisted of field evaluation for traits related to agronomic performance, combining ability, and heterosis. It ...
Genetic interactions between two species of North American deer, Odocoileus virginianus and Ococoileus hemionus
(1990)
The fertility of a first generation male hybrid deer produced from a cross between a male Odocoileus virginianus (white-tailed deer) and a female O. hemionus (mule deer) was assessed. Examination of mitotic chromosomes and ...
Characterization of genes and gene products encoded by the F plasmid transfer region : trbI, traW, traU, trbC, traN, and trbE
(1990)
Genes and gene products encoded by the central part of the F transfer region (between traC and traF) were investigated. The nucleotide sequence of the entire region was determined and all gene products were identified and ...
A survey of DNA content variation and its molecular basis in Helianthus annuus
(1990)
Intraspecific differences in DNA content are frequently due to altered copy number of families of repeated, nongenic sequences for which functional roles have not been determined. There have been several reports of variation ...
