The Arabidopsis E3 ubiquitin ligase PUB4 regulates BIK1 homeostasis and is targeted by a bacterial type-III effector

This study shows that the bacterial effector RipAC targets PUB4 to inhibit PTI by disrupting BIK1 homeostasis.

A bacterial effector uncovers a metabolic pathway involved in resistance to bacterial wilt disease

This study identifies a metabolic pathway involving pyruvate decarboxylases that contributes to plant resistance against bacterial wilt disease, and shows how a bacterial effector inhibits this pathway to promote disease.

The bacterial effector HopZ1a acetylates MKK7 to suppress plant immunity

This study identifies HopZ1a as an effector that acetylates AtMKK7 to suppress plant immunity by inhibiting its kinase activity and downstream immune responses.

SGT1 is not required for bacterial PAMP-triggered immunity

This study shows that SGT1 is not required for bacterial PAMP-triggered immunity in Nicotiana benthamiana and Arabidopsis.

A bacterial effector protein prevents MAPK-mediated phosphorylation of SGT1 to suppress plant immunity

This study identifies RipAC, a bacterial effector that inhibits SGT1 phosphorylation by blocking its interaction with MAPKs, thereby suppressing plant immunity.

Intra-strain elicitation and suppression of plant immunity by Ralstonia solanacearum type-III effectors in Nicotiana benthamiana

This study investigates how Ralstonia solanacearum uses effector proteins to elicit and suppress plant immunity in Nicotiana benthamiana.

A putative ER-PM contact site complex relocalizes in response to Rare Earth Elements-induced endocytosis

The paper identifies a Ca2+-sensitive complex at ER-PM contact sites that relocalizes in response to REE-induced endocytosis, influencing cytosolic Ca2+ signaling and ER-PM communication during stress.

Tomato root transformation followed by inoculation with Ralstonia solanacearum for straightforward genetic analysis of bacterial wilt disease

This paper develops a method for genetic analysis of Ralstonia solanacearum infection in tomato by transforming roots and inoculating with the pathogen, demonstrating resistance via RNAi silencing of SlCESA6.

The IMMUNE-ASSOCIATED NUCLEOTIDE-BINDING 9 protein is a regulator of basal immunity in Arabidopsis thaliana

This study identifies IAN9 and IAP1 as negative regulators of basal immunity in Arabidopsis, with potential applications for improving disease resistance in crops.
