New Genotypes of Found on Strawberry in Florida.

is the most common causal agent of Phytophthora crown rot and leather rot of strawberry, but is also responsible for the disease in Florida. Studies of populations have suggested that different groups of genotypes are associated with different hosts; however, it is not yet clear how many lineages exist globally and how they are related to different production systems. The aim of this study was to determine the genetic relationships of isolates from Florida strawberry with genotypes reported from other hosts, quantify the genetic variation on strawberry, and test for an association with nursery source.

Nematophagous Fungi: A Review of Their Phosphorus Solubilization Potential.

Nematophagous fungi (NF) are a group of diverse fungal genera that benefit plants. The aim of this review is to increase comprehension about the importance of nematophagous fungi and their role in phosphorus solubilization to favor its uptake in agricultural ecosystems. They use different mechanisms, such as acidification in the medium, organic acids production, and the secretion of enzymes and metabolites that promote the bioavailability of phosphorus for plants.

Evaluation of High-Resolution Melting for Rapid Differentiation of Hybrids and Their Parental Species.

species hybrids have been repeatedly reported as causing damaging diseases to cultivated and wild plants. Two known hybrids, and × , are pathogens of Solanaceae and ornamentals, respectively, although the extent of their host ranges are unknown. emerged from hybridization of and an unidentified related species, whereas × emerged from and .
