- A gene-for-gene relationship can evolve only in a discontinuous pathosystem.
- The pathosystem concept is also multidisciplinary.
- This system of locking cannot function in a crop pathosystem in which the host population has genetic uniformity.
- The system of locking is an emergent property that is observable only at the systems level of the pathosystem.
- The n / 2 model is also the most important hypothesis to emanate from the concept of the pathosystem.
- Clayton Oscar Person was the first scientist to study plant pathosystem ratios rather than genetics ratios in host-parasite systems.
- A gene-for-gene relationship is useless in such a pathosystem and, consequently, it will not evolve.
- Another feature of the pathosystem concept is that the parasitism is studied in terms of populations, at the higher levels and in ecologic aspects of the system.
- A crop pathosystem is usually the equivalent of every door in the town having the same lock, and every householder having the same key which fits every lock.
- The main feature of the pathosystem concept is that it concerns parasitism, and it is not concerned with the study of either the host or parasite on its own.
- This alternation of matching and non-matching ( or unlocking and re-locking ) is an essential feature of any system of locking, and it is possible only in a discontinuous pathosystem.
- The n / 2 model ( pronounced either en over two or'half en') suggests the mode of operation of the gene-for-gene relationship in a wild plant pathosystem.
- ""'Pathosystem balance " "'means that the parasite does not endanger the survival of the host; and that the resistance in the host does not endanger the survival of the parasite.
- Conversely, in a continuous pathosystem just one matching allo-infection on each host individual is required for that individual to be parasitised for the rest of its life which, in the case of some evergreen trees, may endure for centuries.
- It can also be argued that the gene-for-gene relationship must function on a basis of heterogeneity in the wild pathosystem because the gross instability of the'boom and bust'of modern plant breeding would have no evolutionary survival value.
- Crops that are derived from a continuous wild pathosystem ( e . g ., aroids, banana, cassava, citrus, cocoa, coconut, date palm, ginger, mango, oil palm, olive, papaya, pineapple, pyrethrum, sisal, sugarcane, sweet potato, tea, turmeric, vanilla, yams ) have no gene-for-gene relationships, not withstanding a few erroneous reports to the contrary.
