But not so much for me: shivering in my tan waders despite four layers of clothing underneath, I crouched forward, aiming my fly upstream toward a rock.
It was pleasant to sit in the cool of the evening with their feet on the great stone and watch the deer come down to drink and, just before darkness, see the herons flying upstream, their color matching the sky so closely they might have been eyes of wind.
We performed PCR analysis on the DSC and SAT Nnd-1 flies with a 5' primer upstream of the deletion reported by Harding-Theobald et al. (2007) and two 3' primers: one downstream of the deletion and one within the deleted sequence.
For fruit fly, 3000 bp upstream and 3000 bp downstream were searched, and for nematode, 1500 bp in each direction.
For the generation of protB-mCherry transgenic flies, the same upstream regulatory region and coding sequence as for protB-eGFP were cloned in the transformation vector p ChabΔSalΔLacZ in-frame to mCherry, and the recombinant plasmid was injected into w embryos (Klemenz et al., 1987) as described previously (Michiels et al., 1993).
Here we used the Gal4-UAS (Upstream Activation Sequence) system to further characterize flies expressing wild-type Drosophila SOD1 (dSOD1) and the mutant human SOD1G85R (G85R) allele in motoneurons and glia.
Transgenic flies expressing human APP under the control of the Gal4 upstream activating sequence (UAS) were provided by Dr. Kalpana White [ 24].
The upstream activating sequence (UAS -α-synuclein, tyrosine hydroxylase (TH)-galactosidase 4 (Gal4), UAS -α-synucleinO, UAS -α-synucleinnd keap1 EY5/(III) fly styrosineve been previously described (Friggi-Grelin et al., 2003; Sykiotis and Bohydroxylase; TH -galactosidase TH -galactosidase 4
Didymo has a natural tendency to grow upstream in fast-moving rivers and creeks, but it can spread by clinging to fishing equipment, especially the felt-bottom waders that fly fishermen use to keep from slipping on river bottoms.
