Defender against cell death (DAD) genes are known to function as negative regulators of cell death in animals. In plants, DAD orthologs are conserved but their role in cell death regulation is not well understood. Here, we report the characterization of the TaDAD2 gene in wheat. The predicted amino acid sequence of TaDAD2 contains typical structural features of DAD proteins, including a signal peptide, three transmembrane regions, and a subunit of oligosaccharyltransferase. Transcripts of TaDAD2 were detected in wheat leaves, culms, roots, florets, and spikelets. The expression level of TaDAD2 was reduced in the initial contact with the stripe rust fungus, subsequently induced and peaked at 18 h postinoculation (hpi), gradually reduced at 24 to 48 hpi, and restored to control level at 72 to 120 hpi. In addition, TaDAD2 exhibited positive transcriptional responses to abiotic stresses after the initial reduction at 1 hpi. Overexpression of TaDAD2 in tobacco leaves inhibited cell death. Furthermore, knocking down TaDAD2 expression by virus-induced gene silencing enhanced the susceptibility of wheat cv. Suwon11 to avirulent race CYR23 and reduced necrotic area at the infection sites. These results indicate that TaDAD2 may function as a suppressor of cell death in the early stages of wheat–stripe rust fungus interaction. However, it is dispensable for or plays an opposite role in hypersensitive response or cell death triggered by an avirulent race of stripe rust fungus at late-infection stages.

AbstractChloroplasts are important for photosynthesis and for plant immunity against microbial pathogens. Here we identify a haustorium-specific protein (Pst_12806) from the wheat stripe rust fungus, Puccinia striiformis f. sp. tritici (Pst), that is translocated into chloroplasts and affects chloroplast function. Transient expression of Pst_12806 inhibits BAX-induced cell death in tobacco plants and reduces Pseudomonas-induced hypersensitive response in wheat. It suppresses plant basal immunity by reducing callose deposition and the expression of defense-related genes. Pst_12806 is upregulated during infection, and its knockdown (by host-induced gene silencing) reduces Pst growth and development, likely due to increased ROS accumulation. Pst_12806 interacts with the C-terminal Rieske domain of the wheat TaISP protein (a putative component of the cytochrome b6-f complex). Expression of Pst_12806 in plants reduces electron transport rate, photosynthesis, and production of chloroplast-derived ROS. Silencing TaISP by virus-induced gene silencing in a susceptible wheat cultivar reduces fungal growth and uredinium development, suggesting an increase in resistance against Pst infection.
