Authors: Dongli Yu / Wen Song / Eddie Yong Jun Tan / Li Liu / Yu Cao / Jan Jirschitzka / Ertong Li / Elke Logemann / Chenrui Xu / Shijia Huang / Aolin Jia / Xiaoyu Chang / Zhifu Han / Bin Wu / Paul ...Authors: Dongli Yu / Wen Song / Eddie Yong Jun Tan / Li Liu / Yu Cao / Jan Jirschitzka / Ertong Li / Elke Logemann / Chenrui Xu / Shijia Huang / Aolin Jia / Xiaoyu Chang / Zhifu Han / Bin Wu / Paul Schulze-Lefert / Jijie Chai / Abstract: 2',3'-cAMP is a positional isomer of the well-established second messenger 3',5'-cAMP, but little is known about the biology of this noncanonical cyclic nucleotide monophosphate (cNMP). ...2',3'-cAMP is a positional isomer of the well-established second messenger 3',5'-cAMP, but little is known about the biology of this noncanonical cyclic nucleotide monophosphate (cNMP). Toll/interleukin-1 receptor (TIR) domains of nucleotide-binding leucine-rich repeat (NLR) immune receptors have the NADase function necessary but insufficient to activate plant immune responses. Here, we show that plant TIR proteins, besides being NADases, act as 2',3'-cAMP/cGMP synthetases by hydrolyzing RNA/DNA. Structural data show that a TIR domain adopts distinct oligomers with mutually exclusive NADase and synthetase activity. Mutations specifically disrupting the synthetase activity abrogate TIR-mediated cell death in Nicotiana benthamiana (Nb), supporting an important role for these cNMPs in TIR signaling. Furthermore, the Arabidopsis negative regulator of TIR-NLR signaling, NUDT7, displays 2',3'-cAMP/cGMP but not 3',5'-cAMP/cGMP phosphodiesterase activity and suppresses cell death activity of TIRs in Nb. Our study identifies a family of 2',3'-cAMP/cGMP synthetases and establishes a critical role for them in plant immune responses. | |||||||||
