Kelp forests in the North Atlantic are at risk of decline their warm temperature distribution margins due to anthropogenic rise and more frequent marine heat waves. To investigate thermal adaptation cold-temperate kelp Laminaria digitata , we sampled six populations, from Arctic Brittany (Spitsbergen, Tromsø, Bodø [all Norway], Helgoland [Germany], Roscoff Quiberon [both France]), across specie...
A Ferns, which are usually colonizing different environments and their roots frequently present mycorrhization, have two adult stages in their life cycle, the sporophytic and the gametophytic phase. This paper describes the experimental mycorrhizal association between Pteris vittata leptosporangiate fern and a strain of Glomus intraradices during the life cycle of the fern, from spore germinati...
• Two cDNAs encoding allene oxide cyclases (PpAOC1, PpAOC2), key enzymes in the formation of jasmonic acid (JA) and its precursor (9S,13S)-12-oxo-phytodienoic acid (cis-(+)-OPDA), were isolated from the moss Physcomitrella patens. • Recombinant PpAOC1 and PpAOC2 show substrate specificity against the allene oxide derived from 13-hydroperoxy linolenic acid (13-HPOTE); PpAOC2 also shows substrate...
P lants (land plants, embryophytes) are of monophyletic origin from a freshwater ancestor that, if still extant, would be classified among the charophycean green algae. Plants, but not charophyceans, possess a life history involving alternation of two morphologically distinct developmentally associated bodies, sporophyte and gametophyte. Body plan evolution in plants has involved fundamental ch...
