Esterase Polymorphism in Meloidogyne konaensis.
The continual detection of a slow (I1) esterase band in greenhouse cultures of Meloidogyne konaensis isolated from the field led to a hypothesis that the nematode may be polymorphic for esterase. A survey of coffee fields demonstrated at least four esterase phenotypes were present in Meloidogyne recovered. An F1 phenotype predominated (60% of the females), but an I1 phenotype was also common (3...
متن کاملQuantitative determination of melatonin in Lamium album flos Quantitative determination of melatonin in Lamium album flos
a HPlc method with dad detection for determination of melatonin in Lamium album flos was developed. The analysis was carried out on rP18 column using mixture of methanol and water (28:72 v/v) as a mobile phase. established calibration curve (r>0.9994), precision (rds values ranged from 0.5% to 1.5%), detection limit (0.025 μg/ml) and quantification limit (0.076 μg/ml) were found to be satisfact...
متن کاملSubstrate-preference polymorphism at an esterase locus of Drosophila mojavensis.
In a larval esterase of Drosophila mojavensis there are alleles whose products preferentially hydrolyze alpha-naphthyl esters, whereas the majority of the alleles hydrolyze preferentially beta-naphthyl esters. In a collection of laboratory stocks alpha alleles have a frequency of 15%. Three different mobilities of alpha alleles were discovered, suggesting a polymorphism rather than a single mut...
متن کاملLocalization , Accumulation , and in Rye ( Secale
In order to understand a physiologi¢ al role of chitinases in rye, the localization and accumulatien of rye seed chitinase-a and -c (RSC-a and -c) in the seeds were studied by imm"nochemical methods. An antiserum specific to the chitin-binding domain (CB-domain), whicb is an N-terminal part of RSC-a, and an antiserum specific to the catalytic region of RSC-a and RSC-c were used. An immunoblot a...
متن کاملMolecular Characterization of Sec2 Loci in Wheat—Secale africanum Derivatives Demonstrates Genomic Divergence of Secale Species
The unique 75 K γ-secalins encoded by Sec2 loci in Secale species is composed of almost half rye storage proteins. The chromosomal location of Sec2 loci in wild Secale species, Secale africanum, was carried out by the wheat--S. africanum derivatives, which were identified by genomic in situ hybridization and multi-color fluorescence in situ hybridization. The Sec2 gene-specific PCR analysis ind...
