Description

Salicylic acid (SA) signaling pathway plays a crucial role in induced disease resistance in rice as in dicots. We have shown that the SA signaling pathway of rice is substantially different from that of Arabidopsis; however, regulatory components involved in the rice SA signaling pathway remain largely unknown. <br>To identify novel components involved in the SA signaling pathway in rice, we used rice-Arabidopsis full-length cDNA overexpressing (FOX) lines. By growing 22,000 Arabidopsis FOX lines overexpressing 13,000 rice full-length cDNAs on media containing 50 μM SA, we selected 96 lines showing SA hypersensitivity. Rice cDNAs identified from these FOX lines encoded proteins with diverse biological functions including transcription, signal transduction, lipid metabolism and transport. Eighty-one lines were categorized into 3 groups based on PR1 expression patterns with and without INA treatments. Experiments are in progress to test whether rice plants overexpressing the cDNAs show altered disease resistance.
