An improved method for transformation of lettuce by Agrobacterium tumefaciens with a gene that confers freezing resistance

Brazilian Archives of Biology and Technology, 2001
An efficient method for constructing transgenic lettuce cultivars by Agrobacterium tumefaciens was described by Torres et al., 1993. In the present work, an improvement of the above procedure is described and applied to transform the cultivar Grand ...

Characterization of Two Novel Heat Shock Protein 70 Transcripts from Sitodiplosis mosellana and Their Response to Larval Diapause and Thermal Stress

Biology
The heat shock protein 70 (Hsp70) family mediates responses to environmental stress in insects. The wheat midge Sitodiplosis mosellana, a worldwide pest, avoids summer and winter temperature extremes by diapause of the third-instar larvae in the soil. To

Enhancing tunnel cold resistance in cold regions with overlapping-tiles cold-proof wall

Case Studies in Thermal Engineering
Tunnels in cold regions are susceptible to freeze damage. The overlapping-tiles cold-proof walls (OTCW) proposed in this study can effectively block cold airflow into the tunnel and mitigate freeze damage. The anti-freezing ability of OTCW was validated through model tests and numerical simulations, and the structural design was recommended based on ...

Did Cold Resistance Influence the Success of the Halobiont Darkling Beetle Centorus rufipes (Coleoptera, Tenebrionidae) During the Pleistocene?

Insects
Centorus rufipes (Gebler, 1833) is the only tenebrionid beetle commonly found in late Pleistocene deposits of southern western Siberia. It is assumed that the reasons for its success during the Last Glacial Maximum could have been its cold resistance and/

Vortex Tunneling and Transport Theory In Two-Dimensional Bose Condensates

, 2006
The tunneling rate t_v of a vortex between two pinning sites (of strength V separated by d) is computed using the Bogoliubov expansion of vortex wavefunctions overlap. For BCS vortices, tunneling is suppressed beyond a few Fermi wavelengths.
