Journal ArticleDOI
DNA barcoding the floras of biodiversity hotspots
Renaud Lahaye,Michelle van der Bank,Diego Bogarín,Jorge Warner,Franco Pupulin,Guillaume Gigot,Olivier Maurin,Sylvie Duthoit,Timothy G. Barraclough,Vincent Savolainen +9 more
TL;DR: Analysis of >1,000 species of Mesoamerican orchids, DNA barcoding with matK alone reveals cryptic species and proves useful in identifying species listed in Convention on International Trade of Endangered Species (CITES) appendixes.
Journal ArticleDOI
Estimation of leaf area and clumping indexes of crops with hemispherical photographs
TL;DR: In this article, CAN-EYE is used to estimate effective and true leaf area index (LAI) from unidirectional gap fractions measured in crops, whereas the true LAI is estimated introducing a clumping index in the Poisson law.
Journal ArticleDOI
Detection of Flavescence dorée Grapevine Disease Using Unmanned Aerial Vehicle (UAV) Multispectral Imagery
Johanna Albetis,Sylvie Duthoit,Fabio Güttler,Anne Jacquin,Michel Goulard,Hervé Poilvé,Jean-Baptiste Féret,Gérard Dedieu +7 more
TL;DR: Evaluation of the feasibility of discriminating the Flavescence doree symptoms in red and white cultivars from healthy vine vegetation using UAV multispectral imagery shows that despite problems of Flavescent dorea and healthy pixel misclassification, an operational Flavescation dorees mapping technique using Uav-based imagery can still be proposed.
Journal ArticleDOI
On the potentiality of UAV multispectral imagery to detect flavescence dorée and grapevine trunk diseases
Johanna Albetis,Anne Jacquin,Michel Goulard,Hervé Poilvé,Jacques Rousseau,Harold Clenet,Gérard Dedieu,Sylvie Duthoit +7 more
TL;DR: Evaluating the potentiality of UAV multispectral imagery to separate symptomatic vines including FD and GTD from asymptomatic vines (Case 1) and FD vines from GTD ones (Case 2) in the Gaillac and Minervois wine production regions of France.
Journal ArticleDOI
A test of _psbK-psbI_ and _atpF-atpH_ as potential plant DNA barcodes using the flora of the Kruger National Park (South Africa) as a model system
TL;DR: This study argues against the ‘multiple barcode approach’ proposed by the plant working group, and instead proposes to keep barcoding plants in line with the approach taken for animals, i.e. using one barcode: _cox1_ for animals and _matK_ for plants.
