We used 52 Arabidopsis (Arabidopsis thaliana) accessions and developed a new set of 137 recombinant inbred lines between Landsberg erecta (Ler) and Nossen (No-0) to explore the genetic basis of phytochrome-mediated responses during deetiolation. Unexpectedly, most accessions showed weak or moderate hypocotyl growth and cotyledon unfolding responses to pulses of far-red light (FR). Crosses betwe...

Pure silver is used extensively in the preparation of high-temperature superconductor wires, tapes, films, and other configurations in which the silver not only shields the superconducting material from the surrounding materials, but also provides a degree of flexibility and strain relief, as well as stabilization and low-resistance electrical contact. Silver is relatively expensive, but at thi...

1. A pure strain of thyroid epithelium was isolated and maintained in active condition for 7 months. At the end of the experiment, the rate of cell multiplication was as great as at its beginning. 2. The thyroid cells grew at the surface of the coagulum as pavement epithelium, and within the coagulum as a glandular structure. 3. The cells did not dedifferentiate, and the lumen of the acini in c...

To understand the plastic ̄ow behavior of commercially pure vanadium under high strain rates, uniaxial compression tests of cylindrical samples are performed using UCSD's enhanced Hopkinson technique. True strains exceeding 50% are achieved in these tests, over a range of temperature from 77 to 800 K at the strain rates of 2500 and 8000 sÿ1. The microstructure of the deformed and undeformed sam...

Previous winery-based studies showed the strains Lalvin® RC212 (RC212) and Lalvin® ICV-D254 (D254), when present together during fermentation, contributed to >80% relative abundance of the Saccharomyces cerevisiae population in inoculated and spontaneous fermentations. In these studies, D254 appeared to out-compete RC212, even when RC212 was used as the inoculant. In the present study, under co...

1. A strain of cartilage cells, obtained from the pars cartilago sclerae of the eye of chick embryos, has been cultivated for more than 3 months in vitro. 2. The initial growth of the cartilage was possible only on the free surface of the coagulum. 3. The hyaline substance disappeared during cultivation in vitro. The succeeding stages of a transformation from small, lymphocyte-like cells into l...
