    Whole-genome sequencing of 3,171 cultivated and 195 wild chickpea accessions is used to construct a chickpea pan-genome, providing insight into chickpea evolution and enabling breeding strategies that could improve crop productivity.

    Analyses of genetic variation and population structure based on over 3,000 cultivated rice (Oryza sativa) genomes reveal subpopulations that correlate with geographic location and patterns of introgression consistent with multiple rice domestication events.

    The oil palm fruit ‘mantled’ abnormality is a somaclonal variant that markedly reduces yield; here, a genome-wide DNA methylation analysis finds that hypomethylation of a single Karma family retrotransposon embedded in a homeotic gene intron is common to all mantled clones and is associated with aberrant splicing and termination of the gene transcript, and that loss of methylation predicts a loss of oil palm yield.

    A survey of organic and conventional potato fields shows that species evenness is greater under organic management. Replicating these levels of evenness in a field trial shows that the evenness of natural enemies found in organic fields promotes pest control and increases crop biomass. This is independent of the identity of the dominant enemy species, so is a result of evenness itself.
