Overview

Study identifies a fungal effector that activates immune responses in peach, suggesting new strategies for disease resistance.

Key Points

  • This research aims to understand how the effector LtSCRE11 from L. theobromae triggers plant immunity in peach and other plants.
  • Identification of LtSCRE11 as a PAMP and virulence factor
  • Examination of its interaction with the L-type lectin receptor kinase PpLecRK-IX.1
  • Analysis of cell death and immune responses in Nicotiana benthamiana and peach
  • Assessment of receptor evolution across different plant lineages
  • LtSCRE11 is recognized by the receptor PpLecRK-IX.1, activating immune responses
  • Binding of PpLecRK-IX.1 to LtSCRE11 involves its lectin domain
  • PpLecRK-IX.1 forms a complex with PpBAK1 to mediate defense signaling
  • Distinct receptors have evolved independently in various plant lineages to recognize LtSCRE11
