On the divergence of genes in multigene families
Theoretical Population Biology, 1987Statistical properties of the amount of divergence of genes in multigene families are studied. The model considered is an infinite-site neutral model with unbiased intrachromosomal conversion, unbiased interchromosomal conversion, and recombination. By considering the time back to the most recent common ancestor of two genes, both the probability of ...

Genetic variation in multigene families [PDF]
Nature, 1977 THE possibility that some important quantitative characters of higher organisms may be subject to multigene families such as that of immunoglobulin variable parts1, poses the problem of reformulation on some of the population genetics theory. The two remarkable characteristics of multigene families as shown by Hood and others1–3—the contraction and ...

Laccase multigene families in Agaricomycetes
Journal of Basic Microbiology, 2016Here we present the results of the exploration of laccase multigene families (MGFs) in basidiomycetous fungi from different taxonomic groups using a next generation sequencing (NGS) technology. In our study, multiple laccase genes were identified in all of the investigated fungi (13 species) from Polyporaceae, Phanerochaetaceae, Meruliaceae ...

The number of alleles in multigene families
Theoretical Population Biology, 1990The probability distribution and moments of the number of alleles present in a sample of homologous chromosomes are studied. It is assumed that there are multiple copies of the gene on each chromosome. When there are only two copies per chromosome or when there are only two or three chromosomes, it is possible to use analytic methods to tackle the ...

The Actin and Myosin Multigene Families
1985The Actin and Myosin Multigene Families: a) a study of the accumulation of their RNA transcripts demonstrates different developmental strategies during skeletal muscle formation, b) a genetic analysis of their chromosomal organization indicates gene dispersion and permits some precise localizations on the genetic map of the mouse.

On the evolution of multigene families
Theoretical Population Biology, 1983Multigene families are classified into three groups: small families as exemplified by hemoglobin genes of mammals; middlesize multigene families, by genes of mammalian histocompatibility antigens; and large multigene families, by variable region genes of immunoglobulins. Facts and theories on these evolving multigene families are reviewed, with special

The olfactory multigene family
Current Opinion in Genetics & Development, 1992A novel multigene family has been identified that is likely to encode odorant receptors on olfactory sensory neurons. Further studies on this gene family are likely to shed light on the molecular mechanisms underlying information coding in the mammalian olfactory system. This review is also published in Current Opinion in Neurobiology 1992, 2:282-288.

Rat Metallothionein Multigene Family
1987Southern blot analysis of rat genomic DNA reveals the presence of numerous sequences homologous to the rat MT-1 gene. We have isolated and characterized by sequence analysis the rat MT-1 gene and three related processed pseudogenes. We discuss mechanisms by which these pseudogenes were formed.

Multigene families and the evolution of complexity
Journal of Molecular Evolution, 1991Higher organisms are complex, and their developmental processes are controlled by the sequential expression of genes that often form multigene families. Facts are surveyed on how functional diversity of genes is related to duplication of genes or segments of genes, by emphasizing that diversity is often enhanced by alternate splicing and proteolytic ...

The multigenic family of monogalactosyl diacylglycerol synthases
Biochemical Society Transactions, 2000Because the synthesis of monogalactosyldiacylglycerol (MGDG) is unique to plants, identified as an important marker of the plastid envelope, involved in a key step of plastid biogenesis and is the most abundant lipid on earth, MGDG synthase activity was extensively analysed at the biochemical and physiological levels.
