Spring dead spot is a disease of bermudagrass ( Cynodon dactylon L. Pers) caused by Ophiosphaerella spp ., of fungi which infect the below ground structures of plants, causing damage to the turf canopy. Previous research suggests that precision management strategies based on manually identified disease within unmanned aerial vehicle (UAV) imagery using GIS software and global navigation satellite systems (GNSS)-equipped spraye...
Despite being landed in commercial cephalopod fisheries, species of Alloteuthis are not yet well defined, with A. subulata and A. media often confused. DNA barcoding combined with morphometric analyses has begun to clarify the distinction between these two morphologically similar species but has been limited in its geographic coverage to date. Herein, we provide DNA barcodes for 228 specimens collected from Guinea Bissau in th...
A traffic light enzyme: acetate binding reversibly switches chlorite dismutase from a red- to a green-colored heme proteinNARA Subscribed
Chlorite dismutase is a unique heme enzyme that catalyzes the conversion of chlorite to chloride and molecular oxygen. The enzyme is highly specific for chlorite but has been known to bind several anionic and neutral ligands to the heme iron. In a pH study, the enzyme changed color from red to green in acetate buffer pH 5.0. The cause of this color change was uncovered using UV–visible and EPR spectroscopy. Chlorite dismutase...
No evidence for phylogenetic constraint on natural defense evolution among wild tomatoesNARA Subscribed
Plant defense traits can be shaped by evolutionary and physiological constraints, as well as local ecological selection. We assessed the relative importance of these factors in shaping defense trait variation across the wild tomato clade (a group of 13 closely related species) using an herbivore bioassay ( Manduca sexta ). With phylogenetic comparative methods, we evaluated patterns of constitutive and induced defense variatio...
