- Root anatomical traits of wild-rices reveal links between flooded rice and dryland sorghum. Mine the rice G genome for sorghum-like root traits.
- The avocado genome informs deep angiosperm phylogeny, highlights introgressive hybridization, and reveals pathogen-influenced gene space adaptation. 2 polyploidy events in its evolution; the Hass is Guatemalan introgressed into Mexican material, recently.

A case study in Eastern Zimbabwe. Differences among maize varieties, but weeding, tillage and intercropping also have an effect. Have yield losses been overestimated, though? Maybe.
- Natural selection contributed to immunological differences between hunter-gatherers and agriculturalists. But the evidence seems to be that the pathogen burden was higher for the hunter-gatherers, which goes counter to everything we’ve been taught by Jared Diamond.

- Household-level drivers of dietary diversity in transitioning agricultural systems: Evidence from the Greater Mekong Subregion. It’s complicated and context-specific, but dietary diversity seems to generally increase with agricultural “development,” i.e. market orientation, specialisation, and intensification. Somewhat surprising? I’ve lost track, frankly.
- Potential role of neglected and underutilized plant species in improving women’s empowerment and nutrition in areas of sub-Saharan Africa. So is increasing cultivation of orphan crops a driver or a consequence of agricultural development? See what I mean? Anyway, useful review.
