The image shows detail of a flower from Petunia hybrida. To avoid self fertilization members of the Solanaceae family, such as petunia, use a system in which components of S-ribonucleases in pistils are detoxified by a collection of 16-20 different S-locus F-box proteins expressed in non-self pollen.

    For more than a decade political stalemate has enforced a de facto ban on the exploitation of genetic modification technologies by European agriculture. It is to be hoped that a recent compromise by the European Parliament will allow reasoned decision-making to proceed.

    Genome editing opens up opportunities for the precise and rapid alteration of crops to boost yields, protect against pests and diseases and enhance nutrient content. The extent to which applied plant research and crop breeding benefit will depend on how the EU decides to regulate this fledgling technology.

    Africa south of the Sahara is going through a major agricultural transformation. Low crop productivity, hunger and pessimism are being replaced by a rapid rise in food production, an increasingly vibrant agricultural value chain and convergence towards a common goal.

    Sequencing ancient DNA from archaeological samples reveals both how maize was transported through North America, and the shifting genomic patterns in response to selection for drought tolerance and sugar content.

    Rubisco catalyses the first step in photosynthetic carbon fixation, but it can be easily poisoned by side-products of its activity. Structural and functional analyses of a protein conserved across plants, algae and bacteria shows how one such blockage is both removed and recycled.

    Ascorbate is synthesized in mitochondria but needed in chloroplasts. Identification of a transporter bridging the chloroplast envelope membranes that separate cell cytoplasm from chloroplast stroma reveals a connection between ascorbate transport and cellular redox homeostasis.

    A 180-year-old ‘law’ in zoology has found its best support so far in a study of floral colour, which not only documents darker plants growing closer to the equator, but also supports the idea that the colour stems from ultraviolet protection.

    Maize originated in southern Mexico from domestication of the wild grass teosinte, and diffused throughout the Americas. Sequenced DNA from archaeological samples spanning 6,000 years, documents the diffusion route and reveals the genes that were specifically selected for climatic and cultural adaptation to the US Southwest.

    Gloger's rule describes how the colouring of animals darkens the closer to the equator they live. Similar global trends have not been observed in plants. Here Gloger's rule holds for the variation of UV pigments in silverweed (Argentina anserine).

    Sugar beet provides around one third of the sugar consumed worldwide and serves as a significant source of bioenergy. A series of laboratory experiments suggests that the transporter BvTST2.1 is responsible for sucrose uptake in the vacuoles of sugar beet taproots.

    Rubisco catalyses the conversion of atmospheric CO2 to organic compounds in photosynthetic organisms. Biochemical and structural analyses suggest that a selective sugar phosphatase found in plants and algae degrades a potent Rubisco inhibitor.

    Plants perceive UVB from sunlight. For this, Arabidopsis thaliana use the receptor UVR8. Dynamic crystallography reveals early signalling structural events and intermediates between the homodimeric (inactive) and monomeric (active) states of UVR8.
