| 英文摘要 | Cold or drought tolerant plants may also show salinity tolerance due to cross adaptation. Chlorella strain NJ-18, a freshwater unicellular green alga from the Antarctica, showed increased salinity tolerance relative to C. vulgaris UETX259, a temperate strain of the same genus. As shown with growth rate, membrane permeability and photosynthetic activity, the Antarctic strain was more tolerant to salinity stress than the temperate one. There were significantly higher levels of soluble sugars and free proline accumulated in NJ-18 than in UTEX259. Under salinity stress, total amino acid contents decreased in UTEX259 but increased in NJ-18. Especially, in NJ-18 exposed to salinity stress, cystine and methionine contents increased about 4- and 1.5-fold compared to cells without the stress. Our results suggest that salinity tolerance may be developed in parallel to cold tolerance in green algae in permanently cold environments. |
