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.

The Plant Journal, 2012
Plants benefit greatly from silicon (Si) absorption provided that they contain Si transporters. The latter have recently been identified in the roots of some higher plants known to accumulate high concentrations of Si, and all share a high level of ...

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.

Two chromosomes with multigene families
Theoretical Population Biology, 1991Watterson's formulae for the distribution, mean, and variance of the number of alleles in common on two chromosomes with multigene families are derived as simpler forms, and extended to chromosomes with an infinite number of genes, each evolving as in an infinitely many alleles model.

Malaria Multigene Families: The Price of Chronicity
Parasitology Today, 2000In this article, Georges Snounou, William Jarra and Peter Preiser discuss the survival strategy of malaria parasites in the light of a novel mechanism of clonal phenotypic variation recently described for a multigene family of Plasmodium yoelii yoelii.

The α-amylase multigene family
Trends in Plant Science, 1997Many α-amylase genes have been cloned from various cereals, and sequence analysis reveals that these fall into two major classes and three subfamilies. In parallel studies, many α-amylase isoforms have been characterized and their corresponding genes identified.

Evolution of the Trappin Multigene Family in the Suidae
Journal of Biochemistry, 1998Trappins are a group of secretory proteins containing a WAP motif with an anchoring domain. Previous studies showed that their genes, especially those of pig, have undergone rapid evolution, which produced trappins with a broad spectrum of actions. To understand the evolution of such a rapidly evolving multigene family, we isolated trappin genes of the
