A Real-Time PCR Assay to Detect and Quantify Root-Knot Nematodes from Soil Extracts.

Root-knot nematodes cause forking and stubbing of the growing carrot root tip, decreasing market value and reducing yield by up to 45%. Since crop damage by these nematodes depends on their initial population densities at planting, preplant detection of potentially low nematode numbers is critical for predicting future yield loss. The aim of this study was to overcome some of the drawbacks of the labor- and time-intensive process of root-knot nematode identification and quantification by developing and field testing a real-time PCR (qPCR) assay.

Cytoglobin deficiency potentiates Crb1-mediated retinal degeneration in rd8 mice.

Purpose: The purpose of this study is to determine the effect of Cytoglobin (Cygb) deficiency on Crb1-related retinopathy. The Crb1 cell polarity complex is required for photoreceptor function and survival. Crb1-related retinopathies encompass a broad range of phenotypes which are not completely explained by the variability of Crb1 mutations.
