- The draft genome of a wild barley genotype reveals its enrichment in genes related to biotic and abiotic stresses compared to cultivated barley. More genes, more alleles in known genes.
- The endemic ‘sugar canes’ of Madagascar (Poaceae, Saccharinae: Lasiorhachis) are close relatives of sorghum. Closer than some actual Sorghum spp.
- Large genetic yield potential and genetic yield gap estimated for wheat in Europe. Long way to go to match the potential, modelled yield of ideotypes.

- Cooking up Diverse Diets: Advancing Biodiversity in Food and Agriculture through Collaborations with Chefs. Yeah, yeah, chefs are great. Now show me the data.
- Multivariate analysis and selection criteria for identification of African rice (Oryza glaberrima) for genetic improvement of indica rice cultivars. Go for high number of productive tillers and early maturity.
- Strategies for Sustainable Use of Indigenous Cattle Genetic Resources in Southern Africa. Not just genetic improvement: also need better nutrition, healthcare, marketing, and infrastructure; integration and empowerment of women and youth; and capacity building, regulatory, and policy frameworks. Not unlike crops, really.
- Population structure of Miscanthus sacchariflorus reveals two major polyploidization events, tetraploid-mediated unidirectional introgression from diploid M. sinensis, and diversity centred around the Yellow Sea. The centre of origin in under water.

- Seed germination and storage studies in seed-fertile Musa indandamanensis and its conservation. Intermediate.
- Cultivated olive diversification at local and regional scales: evidence from the genetic characterization of French genetic resources. Areas with unexpected frosts have been, paradoxically, good for olive diversity.
- Genetic diversity of Nile tilapia (Oreochromis niloticus) throughout West Africa. Corresponds to river basins. Well there’s a shocker.
- Protecting half of the planet could directly affect over one billion people. Add lowest-footprint pixels to PAs until you get to 50% coverage of each ecoregion, then count how many people live in PAs, for good or ill.

Wild millet superstar
A recent paper has identified interesting diversity in the wild pearl millet relative Pennisetum violaceum. Out of 305 accessions, a few were found to have resistance to blast (caused by Magnaporthe grisea) and a few others to rust (caused by Puccinia substriata var. indica). Plants from only one accession were resistant to both diseases: IP 21711 from the ICRISAT genebank. It was originally collected in Chad in 1988. It’s the one in red on the map, which you’ll be able to see better if you click on it.
Sometimes it really is like searching for a needle in a haystack. And that’s only the beginning. Pennisetum violaceum is in the tertiary genepool of the crop, so will be tricky to work with.

- A suite of global accessibility indicators. How long it takes to get from anywhere in the world to settlements of different size. Or took, in 2015.
- A method for computing hourly, historical, terrain‐corrected microclimate anywhere on Earth. Why you might want to move in the first place.
- Genetic strategies for improving crop yields. “Valuable genetic diversity for increasing crop resilience resides in cultivated landraces, heirloom varieties and the wild relatives of crops.”
- A low-cost aeroponic phenotyping system for storage root development: unravelling the below-ground secrets of cassava (Manihot esculenta). But sometimes you have to work hard to get at it: case in point.
- High SNP diversity in the non-toxic indigenous Jatropha curcas germplasm widens the potential of this upcoming major biofuel crop species. And here’s another.
- Genome-wide variation patterns between landraces and cultivars uncover divergent selection during modern wheat breeding. In China and Pakistan anyway.
- Plant populations of three threatened species experience rapid evolution under ex situ cultivation. So don’t cultivate, store seeds instead. Or as well.
- Genes derived from ancient polyploidy have higher genetic diversity and are associated with domestication in Brassica rapa. Polyploidy pre-adapts plants for domestication.
- Genome duplication effects on functional traits and fitness are genetic context and species dependent: studies of synthetic polyploid Fragaria. Case in point.

- A taxonomic monograph of Ipomoea integrated across phylogenetic scales. A whole bunch of new species, and evidence that some 60 species independently developed storage roots before humans were even around. Yes, even sweetpotato.
- Supermarket food purchases and child nutrition in Kenya. Not a bad thing.
Support BCGI’s Global Botanic Garden Fund
Botanic Gardens have long been centres of excellence for plant conservation and many are experts in sustainable practices. This project aims to support smaller botanic gardens that don’t have the expertise or infrastructure required to adopt sustainable practices in saving water, energy, and food.
A very worthy cause.
