  • Acetyl-CoA

    This molecular entity serves as a mediator that transfers carbon atoms to the Krebs cycle, which facilitates their oxidation and consequently produces energy.  

  • Anti-diuretic hormone

    The endocrine secretion discharged from the pituitary gland, which prompts the renal system to retain fluid.  

  • Acute symptom

    Symptoms that develop shortly after infection and that are followed on later leaves by less intense persistent symptoms, or by masking of symptoms. Synonymous with shock symptoms.  

  • Anionic surfactant

    The activity of a solution’s surface is largely determined by the structure of a salt that originates from an organic acid. A chemical compound resulting from the reaction between an organic acid and a base, exhibiting distinctive properties determined by its molecular structure and influencing its behavior at the interface of the solution.  

  • Adult plant resistance

    After the developmental stage of post-seedling, there has been an observation of resistance. However, there is no clear indication of its mode of inheritance or specificity. It is synonymous with the resistance observed in mature plants.  

  • Resistance active

    Resistance can arise due to the host’s reactions against the presence of pathogens or their metabolites. These reactions may include the formation of phytoalexins, the thickening of cell walls, suberization, and other similar responses.  

  • Acquired resistance

    The phenomenon of resistance to external agents or conditions, which is not passed down from parents to offspring, but rather is acquired through certain treatments that make an individual more resistant to these factors, is known as non-inherited resistance conferred by some predisposing treatment.  

  • Gene-for-gene concept

    The notion that the genetic material responsible for resistance and virulence are present in the host and pathogen, respectively.  

  • Axeny

    The concept of inhospitality refers to the passive, rather than active, resistance of a plant to a pathogen. This phenomenon is characterized by the plant’s ability to create a hostile environment for the pathogen, which prevents its growth and proliferation. The term “passive” resistance denotes that the plant is not actively attacking the pathogen, but…

  • Antisporulant

    A substance which inhibits or reduces the formation of fungal spores without eradicating the fungal vegetative growth.
