摘要
Protein S-acylation or palmitoylation is a reversible post-translational modification that influences many proteins encoded in plant genomes.Exciting progress in the past 3 years demonstrates that S-acylation modulates subcellular localization,interacting profiles,activity,or turnover of substrate proteins in plants,participating in developmental processes and responses to abiotic or biotic stresses.In this review,we summarize and discuss the role of S-acylation in the targeting of substrate proteins.We highlight complex roles of S-acylation in receptor signaling.We also point out that feedbacks of protein S-acyl transferase by signaling initiated from their substrate proteins may be a recurring theme.Finally,the reversibility of S-acylation makes it a rapid and efficient way to respond to environmental cues.Future efforts on exploring these important aspects of S-acylation will give a better understanding of how plants enhance their fitness under ever changing and often harsh environments.
