Based on the results of gene expression, enzyme activity assay
and volatile emission, it is concluded that Os03g58300 termed
OsIgl is the bona fide indole-3-glycerol phosphate lyase (IGL) gene
in rice responsible for the production of volatile indole. The
et al., 2010). This extensive type of wounding has not yet been assayed
for indole emission in rice. Volatile emission in maize is induced
by the elicitor volicitin (Alborn et al., 1997) and ZmIgl
transcript is elicited by the application of related fatty acid-amino
acid conjugates (Frey et al., 2004). Fatty acid-amino acid conjugates
(FACs) have been identified in the oral secretion of several
Lepidotera species (Spiteller and Boland, 2003); however, at present
the nature of the proposed elicitor in the FAW oral secretion
is unknown.
