英文摘要	The arabidopsis lsd1 and lol1 proteins both contain three conserved zinc finger domains and have antagonistic effects on plant programmed cell death (pcd). in this study, a rice (oryza sativa) functional homolog of lsd1, designated oslsd1, was identified. the expression of oslsd1 was light-induced or dark-suppressed. overexpression of oslsd1 driven by the cauliflower mosaic virus 35s promoter accelerated callus differentiation in transformed rice tissues and increased chlorophyll b content in transgenic rice plants. antisense transgenic rice plants exhibited lesion mimic phenotype, increased expression of pr-1 mrna, and an accelerated hypersensitive response when inoculated with avirulent isolates of blast fungus. both sense and antisense transgenic rice plants conferred significantly enhanced resistance against a virulent isolate of blast fungus. moreover, ectopic overexpression of oslsd1 in transgenic tobacco (nicotiana tabacum) enhanced the tolerance to fumonisins b1 (fbi), a pcd-eliciting toxin. oslsd1 green fluorescent protein fusion protein was located in the nucleus of tobacco cells. our results suggest that oslsd1 plays a negative role in regulating plant pcd, whereas it plays a positive role in callus differentiation.
