The newly-released FloraQuest app provides mobile device accessibility to the contents of the 1,320 page Flora of the Southern and Mid-Atlantic States, a comprehensive guide to the over 7,000 vascular plants that call the southeastern United States home. Development of the app was spearheaded by Dr. Alan Weakley (Biology Department Adjunct Associate Professor) and Michael Lee. The nearly weightless app is easy to take on a hike, and streamlines plant identification by narrowing results to plants found in the device’s general location. Users can pinpoint specific plants by answering key questions about the plant. Developed by the UNC Herbarium (a department of the North Carolina Botanical Garden) and funded by the Office of the Vice Chancellor for Research through the Carolina Apps Program, the app is available at the Apple Store.
Dr. Gregory P. Copenhaver in conjunction with his collaborators at the University of Birmingham and the IMP-IMBA in Vienna published an article in PLOS Genetics entitled “Arabidopsis PCH2 Mediates Meiotic Chromosome Remodeling and Maturation of Crossovers”. The paper uses advanced microscopy and genetic analysis to examine the meiotic phenotype of a mutant in an AAA+ ATPase called PCH2. The mutant experiences abnormal chromosome organization, decreased crossovers and a defect in CO interference – phenomena that are essential for normal gamete production. READ THE PAPER >>
Congratulations to former Dangl lab post-doc Sarah Lebeis, current graduate BCB student Sur Herrera-Paredes, former GMB graduate student Derek Lundberg and their colleagues and collaborators on a paper just published on SCIENCE Express. The paper is titled “Salicylic acid modulates colonization of the root microbiome by specific bacterial taxa”. This work details genetic functions for defense hormones that regulate the output of the plant immune system in tuning the plant root microbiome. READ MORE >> READ THE PAPER >>
Congratulations to Biology staff members Bill Abbotts and Susan Whitfield, who received their 35th year service awards at the UNC Service Appreciation Reception held recently at the Carolina Club. The reception honored employees who have reached 25, 30, 35, 40, and 45 years of service to UNC during the past year. During the presentation ceremony, the honorees were photographed with Chancellor Carol Folt as she presented each of them with a transparent plaque etched with their years of service.
