Transcriptional analysis of aveR, sav_4189, and sav_4190 by qRT-PCR. (A) Transcriptional profile of sav_4189 during the avermectin fermentation process in WT grown in FM-I. Value of sav_4189 on day 1 was defined as 1. (B) aveR, (C) sav_4189, and (D) sav_4190 transcription levels in WT, D4189, and O4189 grown in FM-I. Value of each gene was calculated relative to WT value on day 2, defined as 1. sav_4189: 91-bp transcript amplified from remainder sav_4189 ORF in D4189 with primers ZX9 and ZX10. P< 0.05, ∗∗P< 0.01, ∗∗∗P< 0.001.
