Symbiotic relationships between cnidarians and dinoflagellates within the genus
Symbiodinium are critically important for the success of coral reefs. These symbionts
provide their hosts with photosynthetically-fixed carbon in exchange for nutrients
and shelter. Symbiodinium is a phylogenetically diverse genus that is often typed by
sequencing the ribosomal internal transcribed spacer...

Gynura aurantiaca is a member of the Senecionaea tribe of the Asteraceae, indigenous to Java. Commonly known as purple velvet plant, this tropical species is well adapted to landscapes in South Florida, but is mostly seen as a potted plant for use in the interiorscape. During February 2013, a local...

Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....
Tests using paired pens of barrows were conducted during a 13 month
period to determine the influence of protein level of the ration on
production traits of market barrows. One member of each pair of six to
ten full- and half-sib pairs was randomly allotted to each pen group;
thus,...
Douglas-fir (DF, Pseudotsuga menziesii) is the most important forest tree in Oregon and is the second most valuable conifer in New Zealand. Phytophthora pluvialis was described (Reeser et al. 2013) from mixed evergreen forests in southwest Oregon. It was subsequently identified as the cause of red needle cast of radiata...
Dead and dying Ceanothus sanguineus, C. velutinus, and C. integerrimus plants grown in a native plant nursery in Oregon for landscape restoration were reported in 2011. Plants were wilted with stem lesions above necrotic roots. Using selective media (Hansen et al. 2012), twelve similar Phytophthora isolates were obtained. DNA sequences...
In August 2012, wilted hop bines were observed in a yard near Seneca Castle, New York,
affecting 10 to 20% of the plants. Affected bines had a dark stem discoloration and wilted
leaves that remained attached after bines were killed. Dark brown to black, erumpent
pycnidia were aggregated in the...

Initially reported in California as the causal agent of sudden oak death (SOD), efforts to limit spread of Phytophthora ramorum in Oregon natural forests have concentrated on quarantine regulations and eradication of the pathogen from infested areas. P. ramorum has four clonal lineages: NA1; NA2; EU1; and EU2 (Grünwald et...
