    UBP12 and UBP13 negatively regulate the activity of the ubiquitin-dependent peptidases DA1, DAR1 and DAR2

    Hannes Vanhaeren et al.
    By inactivating DA1, DAR1 and DAR2 through deubiquitination, UBP12 and UBP13 regulate leaf growth, cell area and endoreduplication.

    Determining the scale at which variation in a single gene changes population yields

    Erica McGale et al.
    Variation in the gene NaMPK4 in plant populations increases reproductive yield, an effect which appears to be independent of soil water availability, neighbor-scale interactions and associations with arbuscular mycorrhizal fungi.

    CCR4, a RNA decay factor, is hijacked by a plant cytorhabdovirus phosphoprotein to facilitate virus replication

    Zhen-Jia Zhang et al.
    A cytorhabdovirus phosphoprotein hijacks host CCR4 to trigger turnover of viral nucleoprotein (N)-bound cellular RNAs, thereby releasing nascent RNA-free N protein molecules to bind viral genomic RNAs for optimal replication.

    A roadmap for gene functional characterisation in crops with large genomes: Lessons from polyploid wheat

    Nikolai M Adamski et al.
    The development of genomic tools and publicly available resources in polyploid wheat provides a framework to understand biologically important traits in crops with large genomes.

    Adaptation of hydroxymethylbutenyl diphosphate reductase enables volatile isoprenoid production

    Mareike Bongers et al.
    Differences in HDR product preference present a novel mechanism in plants to control substrate availability for short- and long-chain isoprenoids.

    Genetic analysis of the Arabidopsis TIR1/AFB auxin receptors reveals both overlapping and specialized functions

    Michael J Prigge et al.
    Genetic analyses reveal that the TIR1/AFB auxin receptors have broadly overlapping functions throughout plant development, but that the AFB1 receptor has a specialized role in a rapid auxin response.

    Reticulon proteins modulate autophagy of the endoplasmic reticulum in maize endosperm

    Xiaoguo Zhang et al.
    Plant reticulons bind Atg8 under ER stress to promote reticulophagy and ameliorate ER stress in the maize endosperm.

    Evolutionarily unique mechanistic framework of clathrin-mediated endocytosis in plants

    Madhumitha Narasimhan et al.
    The examination of the ultra-structure and in vivo dynamics of endocytosis in plants reveal plants unique actin-independent, clathrin-mediated endocytosis mechanisms to overcome their unique physiological properties.

    Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy

    Sona Valuchova et al.
    Light sheet microscopy was used to establish a method for live imaging of cellular events within Arabidopsis flower and for constructing a 3D model of flower at subcellular resolution.
