Forest pathologist, Josh Bronson. Field trial to examine genetic variation in resistance to Sudden Oak Death (Phytophthora ramorum) in tanoak, Douglas-fir, coast redwood, and Port-Orford-cedar. Established near Brookings, Oregon.
More about the project from Richard Sniezko:
A field trial was established in southern Oregon, near Brookings, in March 2019 to examine genetic variation in resistance to Phytophthora ramorum (pathogen causing Sudden Oak Death) in tanoak, as well as susceptibility of conifers Douglas-fir, coast redwood, and Port-Orford-cedar. The trial was a joint effort between USFS (Dorena Genetic Resource Center, FHP), OSU, and ODF.
900 tanoak (Notholithocarpus densiflorus) seedling ‘families’ from 55 Oregon parent trees (and bulked lots) were planted in a field trial to assess genetic resistance to Phytophthora ramorum (pathogen causing sudden oak death, SOD), and to correlate with results of seedling inoculation testing done at Oregon State University. Douglas-fir (Pseudotsuga menziesii), coast redwood (Sequoia sempervirens), and Port-Orford-cedar (Chamaecyparis lawsoniana) seedlings were also planted to test conifer susceptibility.

I will probably delete this explanation later.
I had genetic testing today to see if I have a genetic mutation that might explain why I developed breast cancer at such a young age. Between you and me and the lamp post, I don't think I have the mutation but I wanted to rule it out because if it turns out I have it, I will probably have my ovaries removed.
Nobody else in my family has had this test because they don't trust the insurance companies. But in my case the "cat is already out of the bag" for me because I am sure I would never get insurance anyway because of my "history".
btw this photo was a bitch to take in my dark apartment and no flash. One handed shooting here with a mono-pod and a 1.8 .
this is the crazy tree I told you guys about from the golf course around the corner from our house... I dont get it... I think it is genetically incorrect lol... for real, as we were driving to meet with family yesterday for thanksgiving dinner... this crazy guy is just blooming away... mind you we are in NJ east coast.... crazy stuff...
An international team of scientists led by University of Hawaiʻi at Mānoa researcher Joanne Yew may have discovered a new and effective way to control insect pests that are a threat to agriculture and humans. Yew and her team identified a gene in vinegar flies responsible for the insect’s waterproof coating, which provides them protection from microbes and environmental stress. They nicknamed the gene spidey and announced the findings in a recently published study in PLoS Genetics.

...........................................................................
BACKGROUND:
North Park phacelia (Phacelia formosula) is a member of the waterleaf family (Hydrophyllaceae) is found in “North Park” of north central Colorado, near the small town of Walden. The bright purple flowers and lobed leaf margins make this species easy to spot in July and August. The plant is a biennial, surviving for one year as a rosette of leaves before flowering and dying the following year. The plant is found on barren exposures of the Coalmont Formation that are easily eroded (see the habitat pictures). Roughly 16,000 individuals are known from six separate populations and the entire species is known from an area measuring roughly 10 miles in either direction (north to south, east to west).
The species was discovered, at one location, in 1918 by the Colorado botanist, George Osterhout. Additional sites were not located until 1979. Because of the limited distribution, small population sizes and threats to the species, North Park phacelia was listed as endangered under the Endangered Species Act in 1982. Threats to the species today include: heavy livestock use, off-road vehicle traffic, oil and gas development, residential development, a lack of regulatory mechanisms, and potential effects from climate change.
Genetic and taxonomic research into the species’ relationships with close relatives in Larimer and Grand counties is underway. Further locations of these Phacelia are being sought to better understand these relationships.
Several populations of North park phacelia occur either partially or wholly on private and State lands. Conservation actions on these properties are voluntary. Funding is available to landowners wanting to conserve the species. Please contact Gina Glenne or Ellen Mayo at 970-243-2778 for further information on this species and ways that you can help with conservation and recovery.

When stocking hatchery bass or relocating wild-caught fish, fisheries managers do not transport black bass across Genetic Management Unit boundaries. FWC takes this precautionary approach when moving bass because fish in the different units have been shown to be genetically unique and fish have been shown to survive best in their native environments.
Established in 1964, our Walter Horning Seed Orchard uses genetic testing to grow strong, disease-resistant seeds. Thanks to a cooperative agreement with our partners, including tribal governments, ODF, and local counties, we're able to reforest Oregon with diverse and healthy trees.

The following description of the inoculation process at Dorena is excerpted from pages 72 and 73 of the Whitebark Pine Restoration Strategy for the Pacific Northwest Region. 2009–2013 (available here: ecoshare.info/uploads/documents/WPB_Strategy_PNW_093008cl...):
"The Dorena Genetic Resource Center (Dorena), a component of the regional genetics program of Pacific Northwest Region (and a partner with the regional Forest Health Protection group), has established protocols for blister rust resistance testing of whitebark pine. These protocols are based on those developed and successfully used for screening of western white pine (P. monticola) and sugar pine (P. lambertiana) over the past 5 decades (Danchok et al. 2003).
Resistance testing involves inoculation of young (usually 2-year-old) seedlings with spores of C. ribicola and evaluation of seedlings for up to 5 years after inoculation. Inoculation usually takes place in late August or during September (which coincides with time of natural infection in the field). Seedlings are moved into a climate-controlled inoculation chamber. Temperature within the inoculation chamber is maintained at around 16.7° C (62° F) and relative humidity at 100 percent.
Ribes spp. are the alternative host for C. ribicola, and spores from infected Ribes spp. are necessary to infect the pines. Ribes spp. leaves infected with C. ribicola at the telial stage are collected from forests in Oregon and Washington or from the Ribes garden at Dorena. The Ribes leaves are placed on wire frames above the seedlings, telial side down. Spore fall is monitored until the desired (target) inoculum density of basiospores is reached for each box; the Ribes leaves are then removed. After the target inoculum density is reached for the last box, the temperature is raised to 20° C, and the seedlings are left in the inoculation chamber for approximately 48 hours to ensure spore germination and infection of the pine needles.
Following inoculation, the seedlings are transported outside. The seedlings are evaluated over a period of 5 years for the presence of disease symptoms and mortality. The first symptoms to develop are needle lesions, or ‘spots.’ These are typically assessed approximately 9 months and 1 year after inoculation. Presence and number of stem symptoms along with mortality is assessed annually for 5 years after inoculation."

Knowledge of genetic diversity is one of the important tools used for genetic management of quinoa accessions for plant breeding. This research aimed to molecularly characterize five quinoa genotypes using ISSR markers to reveal genetic polymorphism and identify unique markers for each genotype. Analysis of inter-simple sequence repeats (ISSR) revealed that 10 ISSR primers produced 53 amplicons, out of them 33 were polymorphic and the average percentage of polymorphism was 61.83%. The number of amplicons per primer ranged from 3 (HB-13, HB-10, HB-8 and 17898A) to 10 (HB-15) with an average of 5.3 fragments/primer across the different quinoa genotypes. Data showed a total number of unique ISSR markers of 24; eleven of them were positive and 13 were negative. Using ISSR analysis, we were able to identify some unique bands associated with quinoa genotypes. The genetic similarity ranged from 49% (between Ollague and each of QL-3 and Chipaya) to 76% (between CICA-17 and CO-407). The results indicated that all the five quinoa genotypes differ from each other at the DNA level where the average of genetic similarity (GS) between them was about 59%. The dendrogram separated the quinoa genotypes into two clusters; the first cluster included two genotypes (QL-3 and Chipaya). The second cluster was divided into two groups; the first group included two genotypes (CICA-17 and CO-407) and the second group included only one genotype (Ollague). Our results indicated that ISSR technique is useful in the establishment of the genetic fingerprinting and estimation of genetic relationships among quinoa genotypes. Also, this technique could detect enough polymorphism in the studied quinoa genotypes to distinguish each genotype from the others. Furthermore, the use of these results in the future is important for quinoa germplasm management and improvement as well as for the selection strategies of parental lines that facilitate the prediction of crosses in order to produce hybrids with higher performance. Using ISSR analysis, we were able to identify unique bands associated with quinoa genotypes. These bands might also be used in breeding programs for differentiating among Chinopodium quinoa varieties.
