Abstract
Plants have evolved various means for controlled and organized cell destruction known as programmed cell death PCD In plant immune responses against microbial infection hypersensitive cell death as a form of PCD is a crucial event to prevent the spread of biotrophic pathogens Recent live cell imaging techniques have revealed dynamic features and significant roles of cytoskeletons and the vacuole during defense responses and the PCD Actin microfilaments MFs focus on the infection sites and function as tracks for the polar transport of antimicrobial materials To accomplish hypersensitive cell death further dynamic changes in cytoskeletons are induced MFs play a role in the structural and functional regulation of the vacuole leading to execution of the PCD We here overview spatiotemporal dynamic changes in the cytoskeletons and the vacuoles triggered by signals from pathogens and propose a hypothetical model for MFregulated vacuolemediated PCD in plant immunityThe authors thank to Drs Tatsuaki Goh Kobe University Yasuhiro Kadota The Sainsbury Laboratory Teruyuki Hayashi National Institute of Agrobiological Sciences Natsumaro Kutsuna The University of Tokyo and Toshio Sano Hosei University for helpful discussions This work was supported in part by GrantsinAid Scientific Research on Priority Areas 17051027 to KK 19039008 and 20061008 to SH for Scientific Research on Innovative Areas 21200067 to TK for Exploratory Research 21658118 to KK and for Young Scientists B 21780041 to TK from the Ministry of Education Science Culture Sports and Technology of Japan and by grants from Japan Science and Technology Agency for Adaptable and Seamless Technology transfer Program through targetdriven RD AS221Z03504E to TK
