What is Variation in structure and activity among elicitins from Phytophthora sojae about?

## SUMMARY Transcripts encoding elicitin‐like protein domains were identified from similarity searches of __Phytophthora sojae__ expressed sequence tags and were characterized with regard to molecular structure and elicitor activity. The __P. sojae__ elicitin family consists of at least nine genes with products similar to previously described elicitins (SOJA‐2, SOJB, SOJ2, SOJ3, SOJ5, SOJ6 and SOJ7) or highly diverged from known sequences (SOJX and SOJY). The predicted structural features of seven (SOJA‐2, SOJB, SOJ2, SOJ3, SOJ6, SOJX and SOJY) of the elicitin preproteins were compared. All of the predicted elicitins possess a leader signal sequence and a core elicitin domain. Five (SOJ2, SOJ3, SOJ6, SOJX and SOJY) of the characterized elicitins also contain a variable C‐terminal region. In addition, SOJX and SOJY contain a C‐terminal hydrophobic membrane‐spanning domain. An analysis of expression patterns of the elicitin transcripts showed that SOJA‐2, SOJB, SOJ2, SOJ3 and SOJ6 were expressed in axenically grown mycelia and during infection, but not in zoospores. In contrast, SOJX and SOJY were predominantly and specifically expressed in zoospores. Selected elicitin domains were a
