Method synopsis

Histochemical staining using DAB for hydrogen peroxide and NBT for superoxide detection in plant tissues following herbivore attack. Reveals spatial patterns of oxidative stress responses around feeding damage sites.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Mining the plant-insect interface with a leafmining <i>Drosophila</i> of <i>Arabidopsis</i> (2011), Molecular Ecology. Implementations in other papers (listed below) may differ.

1. Histochemical staining for reactive oxygen species
   Leaves of plants placed with ovipositing female flies for 48h showed evidence of feeding punctures. Staining with DAB revealed H₂O₂ production around feeding punctures and in some cases first instar larvae formed serpentine mines. NBT staining revealed superoxide production patterns around feeding punctures.
   Quantities: Multiple leaves per treatmentDuration: 48 hours exposure to fliesConditions: Standard culture conditions
   Equipment: 3,3'-diaminobenzidine tetrahydrochloride (DAB), nitro blue tetrazolium (NBT), microscope
