Article Synopsis
  • In plants, cell wall fragments like oligogalacturonides (OGs) trigger immune responses by activating signal transduction pathways.
  • Research on the protein DET3, a subunit of the vacuolar H-ATPase, revealed that its knockdown mutant (det3) showed reduced activation of defensive genes and other immune responses when exposed to OGs.
  • The det3 mutant also demonstrated impaired endocytosis of OGs, linking DET3 to the internalization of these molecules, which is vital for maintaining a strong defense against pathogens like Botrytis cinerea.

Root architecture and xylem phenotypic plasticity influence crop productivity by affecting water and nutrient uptake, especially under those environmental stress, which limit water supply or imply excessive water losses. Xylem maturation depends on coordinated events of cell wall lignification and developmental programmed cell death (PCD), which could both be triggered by developmental- and/or stress-driven hydrogen peroxide (H₂O₂) production. Here, the effect of wounding of the cotyledonary leaf on root protoxylem maturation was explored in by analysis under Laser Scanning Confocal Microscope (LSCM).
