    • Using Hyperspectral and Multispectral Indices to Detect Water Stress for an Urban Turfgrass System 

      Badzmierowski, Mike J.; McCall, David S.; Evanylo, Gregory (MDPI, 2019-08-08)
      Spectral reflectance measurements collected from hyperspectral and multispectral radiometers have the potential to be a management tool for detecting water and nutrient stress in turfgrass. Hyperspectral radiometers collect ...
    • Visualization of Glutamine Transporter Activities in Living Cells Using Genetically Encoded Glutamine Sensors 

      Gruenwald, Katrin; Holland, John Todd; Stromberg, Verlyn; Ahmad, Altaf; Watcharakichkorn, Daisy; Okumoto, Sakiko (PLOS, 2012-06-14)
      Glutamine plays a central role in the metabolism of critical biological molecules such as amino acids, proteins, neurotransmitters, and glutathione. Since glutamine metabolism is regulated through multiple enzymes and ...
    • Vortex-induced dispersal of a plant pathogen by raindrop impact 

      Kim, Seungho; Park, Hyunggon; Gruszewski, Hope A.; Schmale, David G. III; Jung, Sunghwan (NAS, 2019)
      Raindrop impact on infected plants can disperse micron-sized propagules of plant pathogens (e.g., spores of fungi). Little is known about the mechanism of how plant pathogens are liberated and transported due to raindrop ...
    • Weed Management in 2050: Perspectives on the Future of Weed Science 

      Westwood, James H.; Charudattan, Raghavan; Duke, Stephen O.; Fennimore, Steven A.; Marrone, Pam; Slaughter, David C.; Swanton, Clarence; Zollinger, Richard (Weed Science Society of America, 2018-02-21)
      The discipline of weed science is at a critical juncture. Decades of efficient chemical weed control have led to a rise in the number of herbicide-resistant weed populations, with few new herbicides with unique modes of ...
    • What is the "real" impact of invasive plant species? 

      Barney, Jacob; Tekiela, Daniel R.; Dollete, Eugene S. J.; Tomasek, Bradley J. (Ecological Society of America, 2013-08)
      Invasive plant species should be evaluated and prioritized for management according to their impacts, which include reduction in native diversity, changes to nutrient pools, and alteration of fire regimes. However, the ...
    • What We Talk about When We Talk about Soil Health 

      Stewart, Ryan D.; Jian, Jinshi; Gyawali, Ayush J.; Thomason, Wade E.; Badgley, Brian D.; Reiter, Mark S.; Strickland, Michael S. (American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-11-01)
      Despite a nationwide emphasis on improving soil health in the United States, current measurement protocols have little consistency. To survey assessment practices, we conducted a meta-analysis of cover crop (n = 86) and ...
    • Wind-driven spume droplet production and the transport of Pseudomonas syringae from aquatic environments 

      Pietsch, Renee B.; Grothe, Hinrich; Hanlon, Regina; Powers, Craig W.; Jung, Sunghwan; Ross, Shane D.; Schmale, David G. III (PeerJ, 2018-09-26)
      Natural aquatic environments such as oceans, lakes, and rivers are home to a tremendous diversity of microorganisms. Some may cross the air-water interface within droplets and become airborne, with the potential to impact ...
    • XcisClique: analysis of regulatory bicliques 

      Pati, Amrita; Vasquez-Robinet, Cecilia; Heath, Lenwood S.; Grene, Ruth; Murali, T. M. (2006-04-21)
      Background Modeling of cis-elements or regulatory motifs in promoter (upstream) regions of genes is a challenging computational problem. In this work, set of regulatory motifs simultaneously present in the promoters of a ...
    • Zoospore interspecific signaling promotes plant infection by Phytophthora 

      Kong, P; Tyler, BM; Richardson, PA; Lee, BWK; Zhou, ZS; Hong, C (Biomed Central Ltd, 2010-12-07)
      Background Oomycetes attack a huge variety of economically and ecologically important plants. These pathogens release, detect and respond to signal molecules to coordinate their communal behaviors including the infection ...
