A site-specific insertion sequence in flax genotrophs induced by environment.
A single-copy 5.7 kilobase (kb) DNA fragment, termed Linum Insertion Sequence 1 (LIS-1), has been identified and characterized. This is one of the DNA changes associated with the environmentally induced heritable changes resulting in stable lines termed genotrophs in flax (Linum usitatissimum). The insertion sequence and its insertion site have been cloned from genomic libraries and sequenced. ...
متن کاملSpecific DNA alterations associated with the environmental induction of heritable changes in flax.
Several flax varieties have been shown to undergo environmentally induced heritable changes resulting in stable lines termed genotrophs. The most notable of these is the variety Stormont Cirrus, also termed "plastic" or Pl. A number of morphological, biochemical and genetic differences are associated with environmental induction of heritable changes in flax. We have studied 5S rDNA alterations ...
متن کاملGenetic instability and hematologic disease risk in Werner syndrome patients and heterozygotes.
Werner syndrome (WRN) is an uncommon autosomal recessive disease in which progeroid features are associated with genetic instability and an elevated risk of neoplasia. We have used the glycophorin A (GPA) somatic cell mutation assay to analyze genetic instability in vivo in WRN patients and heterozygotes. GPA variant frequencies were determined for 11 WRN patients and for 10 heterozygous family...
متن کاملInfrared Imaging of Hh 25/26 and Hh 42/128
Images of the HH 25/26 and HH 42/128 systems obtained in the emission lines of H 2 1-0 S(1), Fe II] 1.64 m, and a 2.22 m continuum lter are reported. A series of aligned H 2 knots has been discovered in association with HH 26, along with a new infrared continuum source located at the center of a previously-discovered CO outtow which may power the HH 26 knots. HIRES images from IRAS are used to ...
متن کاملDetection of phenylketonuric heterozygotes.
Estimation of plasma phenylalanine and tyrosine by an abridged (30 mm) column chromatography procedure was assessed. Plasma phenylalanine and tyrosine concentrations, determined in 112 phenylketonuric obligate heterozygotes and in 88 normal controls, did not differ significantly from other reported series in which the data were obtained by column chromatography. All these series were combined a...
