A set of mapping markers have been designed for Arabidopsis thaliana that correspond to DNA fragments amplified by the polymerase chain reaction (PCR). The ecotype of origin of these amplified fragments can be determined by cleavage with a restriction endonuclease. Specifically, 18 sets of PCR primers were synthesized, each of which amplifies a single(More)
We describe a superfamily of Arabidopsis thaliana retrotransposable elements that consists of at least ten related families designated Ta1-Ta10. The Ta1 family has been described previously. Two genomic clones representing the Ta2 and Ta3 elements were isolated from an A. thaliana (race Landsberg erecta) lambda library using sequences derived from the(More)
The Ta1 elements are a low copy number, copia-like retrotransposable element family of Arabidopsis thaliana. Six Ta1 insertions comprise all of the Ta1 element copies found in three geographically diverse A. thaliana races. These six elements occupy three distinct target sites: Ta1-1 is located on chromosome 5 and is common to all three races (Col-0, Kas-1(More)
BACKGROUND Evaluating the long term benefit of therapy in multiple sclerosis (MS) is challenging. Although randomised controlled trials (RCTs) demonstrate therapeutic benefits on short term outcomes, the relationship between these outcomes and late disability is not established. METHODS In a patient cohort from the pivotal interferon β-1b trial, the value(More)
Poly(A)+RNA isolated from root nodules of yellow lupin (Lupinus luteus, var. Ventus) has been used as a template for the construction of a cDNA library. The ds cDNA was synthesized and inserted into the Hind III site of plasmid pBR 322 using synthetic Hind III linkers. Clones containing sequences specific for nodules were selected by differential colony(More)
Yellow lupin nodule specific sequences were selected by screening of cDNA library prepared from lupin nodule poly(A)+RNA. From about 3,000 clones containing fragments of lupin DNA 150-1,500 base pair long, 7% of clones carrying nodule specific sequences were identified. Among them the most abundant sequence species, represented by 32% clones, encodes(More)
OBJECTIVE This article describes the design of and difficulties inherent in the execution of a long-term, observational trial that sought to assess the validity of short-term measures of multiple sclerosis (MS) (eg, relapse rate, inflammatory lesions) for long-term disease outcomes. METHODS In the original double-blind, placebo-controlled interferon(More)
Fifteen to twenty specific polypeptides of Mr ranging from 15 000 to 90 000 were detected using immunochemical techniques in the lupin root nodules and cell-free translation products of the nodule polysomal RNA. These polypeptides were characteristic for symbiotic state of the host plant and represented 9-18% of total nodule proteins. They were absent in(More)
