3 - Natural Peanut Resistence to Pests
No, particularly not enough is known about peanut natural defensive mechanisms against pests.
Phytoalexins. Peanuts can naturally fight diseases by producing antibiotic compounds (stilbene phytoalexins). However, the exact mechanism of peanut resistance to fungal invasion is not understood. A greater understanding of peanut resistance to pests can lead to new beneficial agricultural practices. Manipulation of host plant resistance is an efficient, economical and environment-friendly approach used to manage many pests and diseases of agricultural crops. In addition, stilbene phytoalexins may be considered potential chemical markers in breeding programs for disease-resistant peanuts.
Interrelationship of stilbene phytoalexin production and resistance of several peanut genotypes to major peanut diseases, including TSWV was also demonstrated for the first time.
Flavonoids and spermidines. Sound seed yield depends heavily on high peanut resistance to pests and uncompromised plant fertility. Peanut flowers have been considered resistant to pests. Compounds that may be responsible for such resistance have not been investigated.
Spermidine compounds, similar to the one above, have been reported to appreciably inhibit HIV-1 protease that is essential for the life-cycle of HIV. One of the compounds also demonstrated high activity against Helicobacter pylori, a major etiological agent in gastroduodenal disorders. Study of biological activity of the new peanut spermidine derivative is anticipated.
