Related PP2C phosphatases Pic3 and Pic12 negatively regulate immunity in tomato to Pseudomonas syringae

This study identifies Pic3 and Pic12 as PP2C phosphatases that negatively regulate tomato immunity against Pseudomonas syringae through flagellin-independent pathways.

Helper NLRs Nrc2 and Nrc3 act co-dependently with Prf/Pto and activate MAPK signaling to induce immunity in tomato

This study shows that Nrc2 and Nrc3 helper NLRs work with Prf/Pto to activate MAPK signaling and induce immunity in tomato against Pseudomonas syringae pv. tomato.

Tomato brassinosteroid-signaling kinase Bsk830 is a component of flagellin signaling that regulates pre-invasion immunity

This study identifies Bsk830 as a tomato kinase involved in flagellin-triggered immunity, showing it regulates pre-invasion immunity and JA signaling.

Loss of function of bHLH transcription factor Nrd1 in tomato induces an arabinogalactan protein-encoding gene and enhances resistance to Pseudomonas syringae pv. tomato

This study shows that loss of Nrd1 function in tomato enhances resistance to Pseudomonas syringae pv. tomato by suppressing the defense gene Agp1.

Spelling changes and fluorescent tagging with prime editing vectors for plants

This paper develops and validates prime editing vectors for plants, enabling large insertions and fluorescent tagging in dicots and monocots.

Ptr1 evolved convergently with RPS2 and Mr5 to mediate recognition of AvrRpt2 in diverse solanaceous species

The paper identifies Ptr1 as a resistance gene in Solanum lycopersicoides that convergently evolved with Mr5 and RPS2 to recognize AvrRpt2 in diverse solanaceous species.

Molecular characterization of differences between the tomato immune receptors Fls3 and Fls2

This study compares the immune responses of tomato receptors Fls2 and Fls3, finding they contribute equally to disease resistance but differ in ROS production, gene expression, and kinase activity.

Tomato wall-associated kinase SlWak1 acts in an Fls2- and Fls3-dependent manner to promote apoplastic immune responses to Pseudomonas syringae

This study shows SlWak1 promotes apoplastic immune responses to Pseudomonas syringae in a Fls2- and Fls3-dependent manner, acting in a complex with these receptors during PTI.

Generation and molecular characterization of CRISPR/Cas9-induced mutations in 63 immunity-associated genes in tomato reveals specificity and a range of gene modifications

This study characterizes CRISPR/Cas9-induced mutations in 63 immunity-associated genes in tomato, revealing mutation types, heritability, and specificity.

Phosphatase PP2C6 negatively regulates phosphorylation status of Pti1b kinase, a regulator of flagellin-triggered immunity in tomato

This study identifies PP2C6 as a phosphatase that dephosphorylates Pti1b kinase, inhibiting its role in flagellin-triggered immunity in tomato.

Mai1 protein acts between host recognition of pathogen effectors and MAPK signaling

The paper identifies SlMai1 as a protein that links host recognition of pathogen effectors to MAPK signaling, enhancing PCD and disease resistance in plants.

The Ptr1 locus of Solanum lycopersicoides confers resistance to race 1 strains of Pseudomonas syringae pv. tomato and to Ralstonia pseudosolanacearum by recognizing the type III effectors AvrRpt2/RipBN

The paper identifies a resistance locus in Solanum lycopersicoides that recognizes type III effectors from Pseudomonas syringae and Ralstonia pseudosolanacearum, providing resistance to bacterial speck disease.

Natural variation for unusual host responses and flagellin-mediated immunity against Pseudomonas syringae in genetically diverse tomato accessions

This study screens genetically diverse tomato accessions for natural variation in their response to Pseudomonas syringae, identifying stem galls and enhanced flagellin responses as key traits.
