Snow algae and lichen algae differ in their resistance to freezing temperature: An ice nucleation study

Popis výsledku v původním jazyce

Introduction: Cryoresistance of snow algae and lichens surviving at extreme environments (i.e. freezing temperature) includes ice nucleation activity. However, interspecific differences in cryoresistance exist according to physiological adjustment of thespecies to in situ conditions. Objectives: We focused on differences in freezing temperatures of snow (Chlamydomonas nivalis, Chloromonas nivalis) and lichen symbiotic algae (Trebouxia erici, T.assymetrica, T.glomerata). The green mesophilic flagellateChlamydomonas reinhardtii was used as an inner standard. We also focused on growth temperature optimum. Methods: Ice nucleation spectrometry (INS) was used to quantify the number and activity of ice nucleating agents. Temperature optimum was measured using a cross gradient cultivator (temperature x light). Results: Pooled data showed that snow algae had higher value of freezing temperature (minus 9.8 deg C) than lichen symbiotic algae (minus 14.7 deg C).
