Enzyme electrophoresis was used to compare the isozyme phenotypes of Oryza sativa, IR31917 (AA genome), and two O. minuta accessions (Om 101089 and Om101141; BBCC genome) for ten enzyme systems. Between the two species, two systems were monomorphic (isocitrate dehydrogenase and alcohol dehydrogenase) and eight were polymorphic (shikimate dehydrogenase, phosphogluconate dehydrogenase, phosphoglucose isomerase, malate dehydrogenase, glutamate oxaloacetate transaminase, esterase, aminopeptidase… Expand
Analysis of introgression from a tetraploid wild species, Oryza minuta, into cultivated rice, O. sativa
The results from this study showed SSR markers are efficient markers for detecting introgression in advanced backcross progenies derived from interspecific cross, O. minuta. Expand
Characterization of interspecific hybrids and backcross progenies from a cross between Oryza minuta and Oryza sativa
Interspecific hybrids obtained from the cross of Oryza minuta could be used to identify the favorable genes of O. minuta and provide a new platform for the genetic improvement of cultivated rice. Expand

Identification of QTL TGW12 responsible for grain weight in rice based on recombinant inbred line population crossed by wild rice (Oryza minuta) introgression line K1561 and indica rice G1025
Sixteen TGW QTL were identified from a recombinant inbred line (RIL) population derived from the cross between the introgression line K1561 of Oryza minuta and the rice cultivar G1025 and the data indicated thirty-two open reading fragments (ORFs) were present in the region. Expand
Reflexos do mecanismo de ação de herbicidas na qualidade fisiológica de sementes e na atividade enzimática em plântulas de arroz
The herbicides of different mechanisms of action in post emergence application, can modify rice physiologic performance and the enzymatic expression varies as a function of the genotype and it is not dependent of the herbicide residual effect. Expand


Comparative and genetic studies of isozymes in resynthesized and cultivated Brassica napus L., B. campestris L. and B. alboglabra Bailey
SummaryEnzyme electrophoresis was used to compare newly resynthesized Brassica napus with its actual parental diploid species, B. campestris and B. alboglabra. Comparisons were also made withExpand
Origin of the genic diversity of cultivated rice (Oryza spp.): study of the polymorphism scored at 40 isozyme loci
An electrophoretic survey of up to forty presumed isozyme loci in Asian and African cultivated rice confirmed that O. glaberrima was domesticated from O. breviligulata independently of O, sativa and suggest that, at the origin of O. sativa, the Indica and the Japonica types were also domesticated independently.

Use of isozymes as chromosome markers in the isolation and characterization of wheat-barley chromosome addition lines
It was found that four disomic chromosome addition lines could be distinguished from one another and from the other three possible lines on the basis of the zymogram phenotypes of these isozymes. Expand
Chromosomal locations of ten isozyme loci in rice (Oryza sativa L.) through trisomic analysis
Chromosomal locations of 10 isozyme loci in rice (Oryza sativa L.) were determined through trisomic analysis, finding that Acp-2 and Pox-2 are known to be linked withAcp-1, so they must also be on chromosome 6. Expand
Cytogenetical Studies of Oryza sativa L. and its Related Species
Pairing of the homologous segments in these allosyndetic pairs was assumed to be carried out at the euchromatic regions of the chromosomes from two different species might have same rate of condensation at various stages of meiosis. Expand
Chromosomal locations of eleven Elytrigia elongata (= Agropyron elongatum ) isozyme structural genes
Evidence is provided that the gene synteny groups which these two species inherited from their common ancestor are conserved, and the valuable role that studies of isozyme genes can play in the isolation, characterization, and maintenance of alien chromosomes, telosomes, and chromosomal segments in wheat strains is further documents.
