A comparison of the differentially expressed auxin-related genes (63 specific to wounding, 50 specific to fungal infection, and 51 specific to cold) revealed that only a few transcripts were common to the different stress factors, including members of AUXIN SIGNALING F-BOX 2-like, auxin-responsive SAUR-like, auxin-responsive IAA-like, auxin response factor (ARF)-like, ABC transporter B (ABCB) and auxin transporter-like protein (LAX). The gene discussed is LAX1; the disease is fungal infectious disease.
