Pathogenicity
Phytophthora
- Phytophthora agathidicida—causes collar-rot on New Zealand kauri (Agathis australis), New Zealand's most voluminous tree, an otherwise successful survivor of the Jurassic
- rhododendron root rot affecting rhododendrons, azaleas, and orchids, and causes bleeding canker in hardwood trees
- squash
- .
- Phytophthora citricola—causes root rot and stem cankers in citrus trees
- Phytophthora fragariae—causes red root rot affecting strawberries
- Phytophthora infestans causes the serious disease known as potato (late) blight: responsible for the Great Famine of Ireland.
- Phytophthora kernoviae—pathogen of beech and rhododendron, also occurring on other trees and shrubs including oak, and holm oak. First seen in Cornwall, UK, in 2003.[4]
- Port Orford cedartrees
- Phytophthora megakarya—one of the cocoa black pod disease species, is invasive and probably responsible for the greatest cocoa crop loss in Africa
- Phytophthora multivora—discovered in analysis of isolates with P. cinnamomi dieback infections of tuart forests of Southwest Australia, which were previously diagnosed as P. citricola. The species was found occurring on many other taxa, so named multivora.[5]
- Phytophthora nicotianae—infects tobacco and onions
- betel nuts
- sudden oak death[6]
- Phytophthora quercina—causes oak death
- Phytophthora sojae—causes soybean root rot
Research beginning in the 1990s has placed some of the responsibility for European forest die-back on the activity of imported Asian Phytophthoras.[7]
In 2019, scientists in Connecticut were conducting experiments testing various methods to grow healthier Fraser trees when they accidentally discovered a new species of Phytophthora, which they called Phytophthora abietivora. The fact that these scientists so readily discovered a new species further suggests that there could be many more species waiting to be discovered.[8]
Reproduction
Phytophthora species may reproduce sexually or asexually. In many species, sexual structures have never been observed, or have only been observed in laboratory matings. In
Zoospores (and zoospores of Pythium, also in the Peronosporales) recognize not only hosts but particular locations on hosts.[9] Phytophthora zoospores recognize and attach to specific root surface regions.[9] This is a high degree of specificity at an early stage of cell development.[9]
