| 摘要 | Hypo-osmotic conditions are among the most stressful environmental factors that affect seaweed physiology and productivity. To improve understanding of hypo-osmotic adaptation and to find genes involved in low salinity stress, we conducted an analysis of expressed sequence tags (ESTs) on the kappa-carrageenan-producing red algae, Kappaphycus alvarezii. Of 454 tentatively unique genes (TUGs), 281 matched protein sequences by BlastX analysis (e value <= 10(-3)), 112 TUGs matched ESTs from other agar-or carrageenan-producing red algae, and 98 TUGs were annotated. The transcriptional profiles of six functional genes from K. alvarezii ESTs were examined. An ATP-binding cassette transporter gene and a sodium phosphate symporter gene were significantly up-regulated, indicating the importance of membrane transport proteins in coping with hypo-osmotic stress conditions.; Hypo-osmotic conditions are among the most stressful environmental factors that affect seaweed physiology and productivity.
