Phytophthora infestans: History, Research & Regions
Phytophthora infestans is an oomycete or water mold, a fungus-like microorganism (oomycete) that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by Alternaria solani, is also often called "potato blight". Late blight was a major culprit in the 1840s European, the 1845–1852 Irish, and the 1846…

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Phytophthora infestans, one of the stronger structural bridges in this analysis connects Phytophthora infestans with Disease management. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
