For the razor clam Solen grandis , siphonal autotomy and regeneration is a necessary means of facing external stress, which is accompanied by a large amount of energy consumption. To explore the function of the ENO4 gene in the siphonal autotomy and regeneration of S. grandis , the full-length cDNA of the ENO4 in S. grandis was cloned and characterized. The full-length cDNA of SgENO4 was 2,773 base pairs (bp), with an 1,851 bp...
