- Unlocking the secrets of extreme seed longevity: the relevance of historic botanical collections to modern research. Claims that very old seeds are still alive are probably exaggerated. Except from genebanks, of course.
- Archaeological assessment reveals Earth’s early transformation through land use. We had transformed the world globally by 3000 years ago.
- Genome-wide association studies in apple reveal loci of large effect controlling apple polyphenols. It should be surprisingly easy to breed really healthy apples. No word on adaptation.

- TR4 reaches South America’s bananas. Be afraid.
- Climate change will affects the region’s rainfed maize too.
- You’ll want sustainably sourced breakfast cereals to put those non-existent bananas on. Hey, companies, what about conserving genetic diversity along with that soil?

- Mortality impact of low annual crop yields in a subsistence farming population of Burkina Faso under the current and a 1.5°C warmer climate in 2100. Low production in any given year responsible for considerable child mortality, which is likely to double because of climate change. If nothing is done.
- Historical phenotypic data from seven decades of seed regeneration in a wheat ex situ collection. Don’t throw any data away.
- Mapping drought-induced changes in rice area in India. 16% less rice area in a drought year compared to a normal year.
- Development of a Multi-parent Population for Genetic Mapping and Allele Discovery in Six-Row Barley. Asian material has flowering time variants found nowhere else.
- Ex situ collections and their potential for the restoration of extinct plants. There’s no excuse for not trying in situ.

- Transforming agricultural land use through marginal gains in the food system. A nudge here, a nudge there, pretty soon you’re talking about a revolution.
- Exploitation of diversity within farmers’ durum wheat varieties enhanced the chance of selecting productive, stable and adaptable new varieties to the local climatic conditions. Some landraces are pretty good.
- Enset in Ethiopia: a poorly characterized but resilient starch staple. Some local crops are pretty good.
- Market‐led options to scale up legume seeds in developing countries: Experiences from the Tropical Legumes Project. Ah yes, PPPs.

- Integrating a newly developed BAC-based physical mapping resource for Lolium perenne with a genome-wide association study across a L. perenne European ecotype collection identifies genomic contexts associated with agriculturally important traits. “Clearly this is not an end-point for L. perenne genomics…” Ok, call me when you get there.

- Global agricultural productivity is threatened by increasing pollinator dependence without a parallel increase in crop diversification. Agricultural diversification going up weakly, possibly undermining pollinators, while proportion of pollinator-dependent crops increasing strongly.
- Food production shocks across land and sea. There are shock hotspots, and overall the frequency of shocks is going up. Whatever can be done?
- National food production stabilized by crop diversity. I wonder.
