    Convergent recruitment of TALE homeodomain life cycle regulators to direct sporophyte development in land plants and brown algae

    Alok Arun, Susana M Coelho ... J Mark Cock
    TALE homeodomain transcription factors have been independently recruited to regulate gametophyte to sporophyte transitions in two complex multicellular eukaryotic supergroups, land plants in Archaeplastida and brown algae in Chromalveolata.

    Three ancient hormonal cues co-ordinate shoot branching in a moss

    Yoan Coudert, Wojtek Palubicki ... C Jill Harrison
    The mosses and angiosperms have independently evolved mechanisms that use the same hormones-auxin, cytokinin and strigolactone-to regulate lateral shoot branching.

    Predicting mosquito infection from Plasmodium falciparum gametocyte density and estimating the reservoir of infection

    Thomas S Churcher, Teun Bousema ... María-Gloria Basáñez
    Identifying and treating those groups of individuals that are most likely to transmit the malaria parasite to mosquitoes could help to control the spread of the disease.

    The Natural History of Model Organisms: The biology of C. richardii as a tool to understand plant evolution

    Sylvia P Kinosian, Paul G Wolf
    The natural history of the model fern Ceratopteris richardii provides opportunities for unique studies and makes it an important system to include in comparative work.

    LEAFY maintains apical stem cell activity during shoot development in the fern Ceratopteris richardii 

    Andrew RG Plackett, Stephanie J Conway ... Verónica S Di Stilio
    Transgenic analysis reveals a role for LEAFY in ferns that supports a trajectory from general to floral meristem-specific function as land plants evolved.

    Gamete expression of TALE class HD genes activates the diploid sporophyte program in Marchantia polymorpha

    Tom Dierschke, Eduardo Flores-Sandoval ... John L Bowman
    The ancestral mechanism to activate diploid gene expression via homeodomain transcription factors was retained in liverworts, an early diverging land plant lineage, and subsequently co-opted during evolution of the diploid sporophyte body.

    Glycosylphosphatidylinositol-anchored proteins as chaperones and co-receptors for FERONIA receptor kinase signaling in Arabidopsis

    Chao Li, Fang-Ling Yeh ... Hen-Ming Wu
    FERONIA receptor kinase interacts with phosphatidylinositol-anchored proteins LORELEI and LLG1 to ensure its proper functional location in the cell membrane and engages them as co-receptors on the cell surface to mediate a broad spectrum of growth and signaling processes.

    Epigenetic reprogramming rewires transcription during the alternation of generations in Arabidopsis

    Michael Borg, Ranjith K Papareddy ... Frédéric Berger
    Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.

    Deep evolutionary origin of gamete-directed zygote activation by KNOX/BELL transcription factors in green plants

    Tetsuya Hisanaga, Shota Fujimoto ... Keiji Nakajima
    Gamete-derived three-amino-acid-loop-extension homeodomain proteins activate zygote development in a strikingly similar manner between basal land plants and green algae, indicating an ancestral role of these transcription factors in green plants.

    Predicting the likelihood and intensity of mosquito infection from sex specific Plasmodium falciparum gametocyte density

    John Bradley, Will Stone ... Teun Bousema
    Malaria transmission between human and mosquito depends on the number of male and female gametocytes in the blood.
