The influence of growth and development temperature on the relative tolerance of photosynthetic tissue to high light stress at chilling temperatures was investigated. Two tuber-bearing potato species, Solanum tuberosum L. cv Red Pontiac and Solanum commersonii were grown for 4 weeks, at either 12 or 24 degrees C with 12 hours of about 375 micromoles per second per square meter of photosynthetic...

Phytophthora infestans (Mont.) de Bary caused the 19th century Irish Potato Famine. We assessed the genealogical history of P. infestans using sequences from portions of two nuclear genes (beta-tubulin and Ras) and several mitochondrial loci P3, (rpl14, rpl5, tRNA) and P4 (Cox1) from 94 isolates from South, Central, and North America, as well as Ireland. Summary statistics, migration analyses a...

First reports of allergic reactions to kiwi fruit occurred relatively late in 1981, when this exotic fruit was becoming more common in nutrition in western countries. The prevalence of kiwi fruit allergy seems to be low in food allergic individuals. Nevertheless IgE mediated reactions after ingestion of kiwi fruit can be most severe, as shown by several cases of anaphylactic shocks. Belonging t...

A recent re-emerging bacterial canker disease incited by Pseudomonas syringae pv. actinidiae (Psa) is causing severe economic losses to Actinidia chinensis and A. deliciosa cultivations in southern Europe, New Zealand, Chile and South Korea. Little is known about the genetic features of this pathovar. We generated genome-wide Illumina sequence data from two Psa strains causing outbreaks of bact...
