Vegetative Hybridity in Phytophthora infestans

Nature, 1970
Phytophthora infestans, the fungus that causes blight in potatoes, probably originated in Mexico1, where two sexually compatible mating groups (A1 and A2) occur with equal frequency and oospores, resulting from normal sexual reproduction, are produced2.

Population Genetics and Intercontinental Migrations of Phytophthora Infestans

Annual Review of Phytopathology, 1992
Our understanding of the population genetics of Phytophthora infestans has increased dramatically during the past decade. In addition to satisfying scientific curiosity, we expect that this understanding will lead to im­ provements in tomato and potato late blight management. We briefly describe the classical population biology/genetics of P.

The development of sporangia of Phytophthora infestans

Mycological Research, 1995
The dynamics of sporulation and zoosporogenesis of Phytophthora infestans in a naturally infected crop of potato cv. Maris Bard and on potted plants of the same cultivar infected artificially with the same fungus are described. Development of sporangiophores and sporangia was synchronous after induction.

Variation in phytophthora infestans

European Potato Journal, 1963
From three field isolates ofPhytophthora infestans sub-isolates were set op on different potato varieties. Their growth rates were assayed on tuber tissue of several potato varieties. Neither in respect of the variation between the original field isolates nor variation arising during the experiment was there any evidence of adaptation by the fungus to ...

Biological specialization in phytophthora infestans

American Potato Journal, 1933
Phytophthora infestans as it occurs in most parts of North America either is not biologically specialized or else the varieties of potatoes and tomatoes now grown are not kinds that reveal the presence of more than one form. The form prevalent in North America is the same as the one which occurred at Moscow in 1928 and at Munich in 1930.

AFLP Linkage Map of the OomycetePhytophthora infestans

Fungal Genetics and Biology, 1997
Here we present the first comprehensive genetic linkage map of the heterothallic oomycetous plant pathogen Phytophthora infestans. The map is based on polymorphic DNA markers generated by the DNA fingerprinting technique AFLP (Vos et al., 1995, Nucleic Acids Res. 23: 4407-4414). AFLP fingerprints were made from single zoospore progeny and 73 F1 progeny

Studies on the mechanism of action of cymoxanil in Phytophthora infestans

Pesticide Biochemistry and Physiology, 1987
Abstract Colony growth and germ tube emergence of sporangia and encysted zoospores of Phytophthora infestans were highly sensitive to cymoxanil (ED50 0.5–1.5 μg/ml), whereas differentiation of sporangia and zoospore release were insensitive at concentrations up to 100 μg/ml. Treated sporangia did not show distorted germ tubes.

Krumpirova plijesan (Phytophthora infestans)

Glasilo biljne zaštite, 2001
Prvi znaci bolesti mogu se očekivati pred kraj cvatnje ili neposredno nakon cvatnje, ali to ovisi o kišama i temperaturama. Simptomi su najuočljiviji na listu, premda mogu biti napadnute peteljke lista, stabljika i gomolji. Zaraza se najčešće javlja na lišću koje je najbliže tlu.

ALLELIC DIVERSITY OF THE POPULATION OF PHYTOPHTHORA INFESTANS IN CHINA

Acta Horticulturae, 2009
Introduction of resistance genes from wild Solanum species into potato cultivars is considered the most promising and environmentally safe approach to achieve late blight resistance. An R-gene stacking breeding program using cisgenesis is planning to trial its products in China.
