Predictor of Natural Disordered Regions or PONDR is one of the best available algorithms for predicting the likelihood that a given amino acid residue is in a region of intrinsic disorder, based on the surrounding amino acid sequence and amino acid composition.

Tomato plants produce tomatine, a compound that is closely related to avenacin. Only certain pathovars of the fungal pathogen Septoria lycopersici can cause disease on tomatoes, and these pathovars produce a glucosidase that can detoxify tomatine.

According to Optimal Defense Hypothesis, 

Young tissues not only contain the highest levels of constitutive secondary compounds, they are also more responsive to herbivory. Thus, younger leaves exhibit more robust inducible defenses to herbivores than older leaves.

Constitutive defenses are costly to the plant. The production of secondary metabolites requires a significant energy investment derived from primary metabolism, which is then unavailable for use in growth and reproduction.

Inducible defense against pests or pathogens, involve both a wound response and the recognition of certain compounds abundant in the insect’s saliva or regurgitant. 

These compounds belong to a broad group of chemicals called elicitors
