Fig. 6From: Transcriptomic analysis reveals the key role of histone deacetylation via mediating different phytohormone signalings in fiber initiation of cottonVerification of some key genes transcription associated with TSA and determination of phytohormones content in response to TSA during fiber initiation. A The expression profiles of key genes associated with phytohormone pathways were determined in the mock and TSA-treated ovules by RT-qPCR. All the expression levels were normalized to UBQ7, the gene was then expressed as a ratio relative to mock, which was set to a value of 1. Primers are listed in the Additional file 4: Table S4. B Different plant hormone levels were determined in TSA-treated ovules of − 1 DPA culture for 5 days. Error bars indicated SD (standard deviation) of three biological replicatesBack to article page
