a
Only verified substances that were up- or down-regulated by V. longisporum ELV43 VOCs are shown.
b
Arrow up (↑) symbolizes that the corresponding substance is upregulated, while arrow down (↓) symbolizes a downregulation by V. longisporum ELV43 VOCs. N.a. (not available) means that a putative function could not be found. Asterisk (
*
) symbolized that the up- or downregulation was statistically significant (p < 0.05).
