Grain picking in the green Sahara

Wild cereals, weeds in modern agriculture, are traditional food plants in subsistence economies. Early Holocene millet and sorghum seeds from central Sahara provide early evidence of cultivation without domestication by African foragers.

    Sixty years ago, Francis Crick articulated the central dogma of molecular biology to explain the sequential information flow between genes and proteins. Nowadays our understanding of genes and the information they convey is no longer limited to the single-molecule level.

    The recently published reference genome of Aegilops tauschii provides new insights into the originator of the D genome donor of hexaploid wheat. This will be a foundation for exploring the genomic diversity underpinning adaptive traits in wheat, and ultimately advance wheat improvement efforts.

    A major transitional step in Earth’s history was the conquest of land by plants, which fundamentally changed carbon cycling and elevated oxygen levels. In a moss model of early land plants, three out of six MIKCC-type MADS-box transcription factors ensure external water conduction and the function of motile sperm.

    Auxin-induced callus formation, known as a type of cell reprogramming, involves several transcription factors that act in lateral root initiation for plant development. Now, a new partnership of transcription factors is identified to reveal the regulatory network of auxin-induced cell reprogramming.
