Overview
Biotic stress is the adverse pressure imposed on plants by other living organisms, including pathogens such as fungi, bacteria, viruses, and oomycetes, as well as nematodes, insects, parasitic plants, and competing weeds. It is distinguished from abiotic stress, which arises from non-living factors such as drought, salinity, and temperature extremes, although the two frequently interact in the field and share overlapping signalling and defence responses. Biotic stress damages tissues, disrupts physiology, and reduces crop yield and quality, making resistance a central objective in plant biology and agronomy. At the molecular level, plants perceive attack through receptor-mediated recognition of pathogen- and damage-associated signals and respond with immune cascades, hormone-mediated defences, and the reprogramming of gene expression, including roles for regulatory molecules such as plant circular RNAs. Root system architecture and root phenotypic plasticity contribute to tolerance by influencing how plants withstand combined biotic and abiotic challenges. Research in this area characterizes genetic diversity and morphological and proteomic variation among genotypes, screens germplasm and selection indices for resistance and tolerance, and exploits phylogenetic and trait-based analyses in crops such as chilli, chickpea, pepper, and cocoyam. Understanding the mechanisms and genetic basis of biotic stress responses underpins the breeding of resilient cultivars and sustainable strategies for crop protection.
