Abstract In order to aid gene discovery and uncover genes
responding to abiotic stressors in stress-tolerant brown
algae of the genus Fucus, expressed sequence tags (ESTs)
were studied in two species, Fucus serratus and Fucus
vesiculosus. Clustering of over 12,000 ESTs from three
libraries for heat shock/recovery and desiccation/rehydra-
tion resulted in identification of 2,503, 1,290, and 2,409
unigenes from heat-shocked F. serratus, desiccated
F. serratus, and desiccated F. vesiculosus, respectively.
Low overall annotation rates (18­31%) were strongly
