    To reduce climate warming we must stop adding CO2 to the atmopshere, and develop approaches for removing it. Adding crushed, fast-reacting silicate rocks to croplands could improve productivity, restore soil quality and reduce atmospheric CO2.

    Bacterial pathogens have a multitude of effectors that target plant host cells and promote disease. A case is made for a new suspect, phytate, as a target of a novel phytase activity for a type III effector of Xanthomonas.

    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.

    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.

    In plants, RNA-directed DNA methylation requires non-coding RNAs transcribed by RNA polymerase V (Pol V). A modified global nuclear run-on protocol and deep sequencing to capture Pol V nascent transcripts uncovered unique characteristics of Pol V RNAs.

    Knowledge of three-dimensional (3D) genome structure and how polyploidization shapes it remains poor. A study now characterizes and compares 3D genomes for diploid and tetraploid cotton, showing how allopolyploidization affects 3D genome architecture and transcriptional regulation.

    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.

    The evolution and phylogenetic placement of gnetophytes have remained elusive. The draft genome for a gnetophyte, Gnetum montanum, is now reported. Comparative analyses identify genomic features distinguishing gnetophytes from other gymnosperms.

    Plants have remarkable regeneration ability under the control of phytohormones such as auxin and cytokinin. Here, the researchers identify a heterodimer that consists of two key transcription factors mediating the auxin-induced callus formation.

    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.
