Earth Engine and crop wild relatives
The other recent Google Earth innovation is Earth Engine, where you can check out a bunch of interesting visualizations of environmental data. Spurred by something Julian said, I downloaded the MODIS VCF global tree cover change dataset (2000-2005). And then I went to Genesys and downloaded data on wild beans (Phaseolus spp). It was not very difficult to put the two together in Google Earth. In the map below, which just looks at central Mexico, orange means high deforestation, and green afforestation. Is it me, or do germplasm accession seem to be concentrated in areas of high deforestation? Anyway, with a little work, this could be a cheap and cheerful way to identify particularly threatened areas for germplasm collecting.
Who wants to be the first to put crop wild relatives data in Earth Engine?
Tajikistan landscape with wild relatives
Wild relatives of apples, cherries, almonds and grapes are to be found in this landscape, apparently. More later on my trip.
A brave new world for crop wild relatives
Thanks to Dr Brian Ford-Lloyd of the University of Birminghan in the UK for the following contribution.
A ground breaking publication in Nature Genetics points to the future for the genetic evaluation of crop wild relative germplasm. A group of Chinese scientists have used Illumina Next Generation Resequencing to produce whole genome sequences of 17 wild species of soybean. Only 17 wild species? But this is just the start for evaluating crop wild relatives on a completely different level than before — adding a different perspective to the analysis of genetic diversity, the identification of important adaptive differences between species, and locating novel allelic variation that can be used in crop improvement. One important result from the work is that they uncovered genetic variation in the wild species that has been clearly lost in cultivated material.
