OsMYC2-responsive genes in OsMYC2-overexpressing transgenic rice


ABSTRACT: A rice transcription factor OsMYC2 plays important role in the regulation of defense responses in rice. To clarify the OsMYC2-responsive genes, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, Agilent Technologies, Redwood City, CA, USA). As a result, many defense-related genes including pathogenesis-related (PR) genes were upregulated in the OsMYC2-overexpressing transgenic rice. Overall design: An Agilent Rice Oligo Microarray (44k; Agilent Technologies, Redwood City, CA, USA) was used for the microarray analysis. Total RNA was extracted from leaf blades of four-leaf stage rice plants. Line 14 was used as the OsMYC2-overexpressing transgenic rice plant. For each biological replicate, material from at least three rice plants was pooled to provide a single sample for RNA extraction. We performed 3 biological replicates for each treatment. All microarray procedures and data analyses were performed according to the manufacturer’s instructions. RNA integrity was checked using an Agilent 2100 Bioanalyzer (Agilent Technologies, Redwood City, CA, USA). Total RNA (100 ng) was labeled with Cy-3 using an Agilent Low Input Quick Amp Labeling Kit, One-Color (Agilent Technologies). Fluorescently labeled targets were hybridized to Agilent Rice Oligo Microarrays for 17 h at 65°C. After hybridization, following wash processes were performed according to the manufacturer’s instructions, and hybridized microarrays were scanned using an Agilent Microarray Scanner (G2565CA; Agilent Technologies). Feature extraction software (Agilent Feature Extraction; Agilent Technologies) was used to delineate and measure the signal intensity of each spot in the array, and to normalize intensities. The background was measured around each spot as local background, calculated by the Feature Extraction software. Statistical data extraction processes were performed according to the manufacturer’s instructions.

JASMONATE ZIM-domain (JAZ) proteins act as transcriptional repressors of jasmonic acid (JA) responses and play a crucial role in the regulation of host immunity in plants. Here, we report that OsMYC2, a JAZ-interacting transcription factor in rice (Oryza sativa L.), plays an important role in the resistance response against rice bacterial blight, which is one of the most serious diseases in rice, caused by Xanthomonas oryzae pv. oryzae (Xoo). The results showed that OsMYC2 interacted with some O  ...[more]
