1Department of Agronomy, Horticulture, and Entomology, Texas Tech University, 79409-4169, Lubbock, TX, USA.
Summary
Genetic polymorphism for esterase enzymes was studied in sainfoin (Onobrychis) species. Unique banding patterns were observed, revealing significant genetic diversity and potential for marker development.
Area of Science:
- Plant genetics
- Enzyme polymorphism
- Biochemical markers
Background:
- Enzyme polymorphism is crucial for population and genetic studies.
- Limited information exists on esterase variability across sainfoin (Onobrychis) species.
Purpose of the Study:
- To investigate genetic polymorphism for esterase in 17 Onobrychis species and three cultivars.
- To establish esterase isozyme banding patterns as potential genetic markers.
Main Methods:
- Analysis of esterase isozyme banding patterns across different Onobrychis species and cultivars.
- Comparison of banding patterns to identify unique profiles and genetic similarities.
Main Results:
- Three esterase banding regions (EST1, EST2, EST3) were identified with varying band numbers.
- Unique banding patterns were observed for most materials, with isozyme 1 being common.
- Significant genetic diversity was evident, with percent similarity ranging from 0% to 79%.
Conclusions:
- Esterase isozyme analysis reveals substantial genetic diversity within the Onobrychis genus.
- Isozyme banding patterns can potentially serve as markers for desirable agronomic and quality traits.

01:25Genetic Variation
1.7K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

01:28Pharmacogenetics of Phase I Enzymes: Cytochrome P450 Isozymes
349
Cytochrome P450 (CYP450) enzymes are a superfamily of heme-containing monooxygenases that play a pivotal role in Phase I drug metabolism by catalyzing oxidation and reduction reactions.These enzymes transform lipophilic xenobiotics into more hydrophilic metabolites, facilitating subsequent Phase II conjugation and eventual excretion. The CYP450 family is classified into families (e.g., CYP1–CYP3) and subfamilies (e.g., CYP2A, CYP2C), based on amino acid sequence homology.CYP450...

01:09Mutation, Gene Flow, and Genetic Drift
53.1K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

01:19Enzyme Kinetics
81.2K
Enzymes speed up reactions by lowering the activation energy of the reactants. The speed at which the enzyme turns reactants into products is called the rate of reaction. Several factors impact the rate of reaction, including the number of available reactants. Enzyme kinetics is the study of how an enzyme changes the rate of a reaction.

01:19Turnover Number and Catalytic Efficiency
16.1K
The turnover number of an enzyme is the maximum number of substrate molecules it can transform per unit time. Turnover numbers for most enzymes range from 1 to 1000 molecules per second. Catalase has the known highest turnover number, capable of converting up to 2.8×106 molecules of hydrogen peroxide into water and oxygen per second. Lysozyme has the lowest known turnover number of half a molecule per second.

02:05Gene Evolution - Fast or Slow?
6.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
