| Nothofagus dombeyi (Mirb.) Blume is an evergreen tree, pioneer in habitats subject to unfavorable environmental conditions as nighttime freezing temperatures and low water content. It inhabits zones characterized by cold Winter with freezing temperature and Spring frosts reaching to -5°C. Furthermore, it has the capacity to maintain a functional photosynthetic apparatus at low temperatures. We postulated that N. dombeyi is capable to accumulate dehydrins in leaves in response to cold. Seasonal variation in dehydrins, soluble total proteins, and cryoprotective activity in vitro of protein extracts of N. dombeyi leaves were analyzed during the years 2004 and 2005. A dehydrin-like protein of 47-kDa was immunologically identified; this protein was present only... |
