Identifying putative calcification and decalcification genes in the geniculate coralline alga, Calliarthron tuberculosum.

ABSTRACT: Coralline algae form highly calcified thalli, creating key substrate that promotes biodiversity in nearshore marine environments. Although calcification and decalcification are critical for coralline growth and ecological function, their underlying mechanisms are not fully understood. We capitalized on the unique morphology of articulated coralline algae, assembling tissue-specific transcriptomes for calcified (intergenicular), uncalcified (genicular), and actively decalcifying (young genicular) tissues in the coralline alga Calliarthron tuberculosum and compared gene expression to identify putative calcification and decalcification genes. We captured the greatest differences in gene expression between calcified and uncalcified tissue, with 17.7% (5238 genes) of the genes in the transcript
