Description: We assessed the heat tolerance of microscopic Saccharina latissima sporophytes under heat stress and in response to gametophyte priming. We primed S. latissima gametophytes (Lofoten 2023; 15°C clonal culture; n = 7) for 3 weeks at 0°C, 10°C, and 20°C and induced gametogenesis at 10°C for 2 weeks. Resulting microscopic sporophytes were subjected to a 14-day heat stress treatment at 20°C, 21.5°C, and 23°C, where we counted the number of alive and dead sporophytes and calculated the survival rates in relation to day 0. The laboratory experiment was carried out at the Alfred Wegener Institute in Bremerhaven, Germany.
