​​Genotyping of Phytophthora infestans in Eastern Africa Reveals a Dominating Invasive European Lineage​​

​ Since its first appearance in 1941, late blight has caused important losses to potato production in the eastern-Africa region. ​Forbes et al. hypothesized that the causal Phytophthora infestans strains originated from Europe. Their evidence supports this hypothesis. 

​​The June issue of Plant Disease​​ sets a record with 372 pages!

​The previous record was 332 pages. Thank you to all the authors, reviewers, and editors who contributed their time and expertise. ​

The tomato microbiota​ is the result of a selective process that progressively differentiates between rhizosphere and root microhabitats and is fine-tuned by the type of nitrogen fertilizer applied.​

​​
Covering one of the most exciting areas of research in the molecular plant-microbe field, this focus issue ​includes current topics such as cellular RNA hubs, plasmodesmal functioning, and mechanisms of host defense suppression.

"A plant's microbiome profoundly impacts its health and development," explains Brooke Bissinger, an entomologist who recently published a study on sweetpotatoes​ in Phytobiomes Journal. "We sought to better understand the sweetpotato microbiome by characterizing it within and between actual working farms."

The Food and Agriculture Organization estimates that 25% of global food crops are contaminated with different types of fungal toxins, such as aflatoxins, highly toxic and carcinogenic substances produced by certain species of the fungus Aspergillus. New research published in Plant Disease reveals a deeper understanding of how members of this same fungus species can be used to reduce aflatoxins in crops. ​
