The Induced Resistance Lexicon: Do's and Don'ts.

Area of Science:

• Plant biology
• Immunology
• Biochemistry

Background:

• Plants have evolved sophisticated immune systems, including constitutive and inducible defenses, to protect against biological threats.
• Induced resistance (IR) is a key plant defense mechanism where plants develop enhanced resistance upon perceiving specific stimuli.
• Current terminology in the IR field is inconsistent, leading to confusion and hindering scientific progress.

Purpose of the Study:

• To address the confusing lexicon in plant induced resistance (IR) research.
• To propose a standardized code of practice for describing IR phenotypes.
• To enhance uniformity and consistency in scientific communication within the IR field.

Main Methods:

• Review and analysis of existing literature on plant induced resistance (IR).
• Development of a framework based on two key phenotypical aspects: local vs. systemic resistance and direct vs. primed defense responses.
• Proposal of a widely applicable code of practice for IR terminology.

Main Results:

• Identified inconsistencies and ambiguities in the current terminology used to describe plant induced resistance (IR) phenotypes.
• Established a clear framework for categorizing IR phenotypes based on spatial (local/systemic) and mechanistic (direct/primed) aspects.
• Provided a proposed code of practice to standardize the description of IR.

Conclusions:

• Standardized terminology for plant induced resistance (IR) is crucial for clear scientific communication.
• The proposed framework and code of practice will improve consistency and reduce misinterpretations in IR research.
• Implementing this standardized approach will facilitate accessibility and enhance the impact of research on plant defense mechanisms.
