Overview

Systematic review highlights biochemical resistance in crops against Meloidogyne spp., suggesting integrated management strategies in Sub-Saharan Africa.

Key Points

  • This review aims to assess the biochemical mechanisms of plant defense against Meloidogyne spp. in Sub-Saharan Africa and globally.
  • Systematic review of 30 experimental studies from 17 countries, focusing on biochemical responses of crops to Meloidogyne spp.
  • Literature sourced from PubMed, Web of Science, Scopus, and AGRIS using strict inclusion criteria.
  • Emphasis on enzymatic assays and metabolite profiling of staple crops like maize, yam, and tomato.
  • Resistance linked to increased peroxidase and phenylalanine ammonia-lyase activity, and phenolic compounds.
  • Key phytohormone pathways activated include salicylic acid, jasmonic acid, and ethylene.
  • Identified limitations include methodological heterogeneity and limited field validation, highlighting the need for standardized protocols.
