Isolation and characterization of the tissue and development-specific potato snakin-1 promoter inducible by temperature and wounding
Snakin-1 (StSN1) is a broad-spectrum antimicrobial peptide isolated from Solanum tuberosum. Homologous proteins have been identified in a wide range of species but there is no apparent consensus in the roles they play. A 1394 bp fragment of the 5’upstream region of StSN1 gene, designated P...
