A Tortula ruralis cDNA, Rp115,encoding a predicted polypeptide with significant similarity to the large-subunit ribosomal protein L15 (RPL15) was isolated from a desiccated gametophyte cDNA library, and is the first L15 homologue identified from a bryophyte. The deduced 203 amino acid polypeptide is approximately 24.1 kDa, with a predicted pI of 11.1,and shares extensive identity with rat RPL15 deduced polypeptide (>57%). RNA blot hybridization using total RNA demonstrated that Rpl15 is constitutively expressed in moss gametophytes during a desiccation-rehydration cycle and that Rpl15 mRNA transcripts are maintained in desiccated gametophytes as conserved mRNAs.
