Transcriptomic analysis of rice cultivars with distinct resistance mechanisms to <i>Xanthomonas oryzae</i> pv. <i>oryzicola</i> reveals novel components and candidate genes associated with bacterial leaf streak.

ABSTRACT: Xanthomonas oryzae pv. oryzicola causes bacterial leaf streak, a rice disease that can lead to substantial yield losses. Although an xa5-based signaling pathway is known to confer resistance to this disease, alternative stable and broad-spectrum resistance mechanisms will be critical for sustainable management. In this regard, we characterized NDCMP49, a Thai rice variety with strong resistance to bacterial leaf streak but lacking xa5-based resistance. Transcriptomes of NDCMP49 were compared with DV85, a rice variety with xa5-based resistance, and HCS, a bacterial leaf streak susceptible variety, at 0- and 9-hours post-inoculation with X. oryzae pv. oryzicola. Analysis of differentially expressed genes revealed a less transcriptional respons
