    A calcineurin-mediated scaling mechanism that controls a K+-leak channel to regulate morphogen and growth factor transcription

    Chao Yi et al.
    Calcineurin regulates an electrophysiological mechanism that activates the transcription of specific developmental genes in a heirarchical manner to scale fish appendages.

    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.

    Active suppression of a leaf meristem orchestrates determinate leaf growth

    John Paul Alvarez et al.
    A meristem acting at the margins of Arabidopsis leaves is suppressed by factors acting primarily in leaves and other determinate organs.

    Combining growth-promoting genes leads to positive epistasis in Arabidopsis thaliana

    Hannes Vanhaeren et al.
    Pairwise combinations of growth-promoting genes regulating distinct cellular mechanisms lead to synergistic effects on leaf growth, and hence greatly increased leaf size.

    Nomadic-colonial life strategies enable paradoxical survival and growth despite habitat destruction

    Zhi Xuan Tan, Kang Hao Cheong
    By modelling organisms that alternate between individual and colonial lifestyles, the well-known Parrondo's paradox can emerge in an ecological setting without the need for stochastic environmental variation.

    A stochastic multicellular model identifies biological watermarks from disorders in self-organized patterns of phyllotaxis

    Yassin Refahi et al.
    A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.

    Two-signal requirement for growth-promoting function of Yap in hepatocytes

    Tian Su et al.
    The Yap pathway requires two signals to promote organ growth: a cell intrinsic Hippo signal and a signal induced by injury or inflammation.

    Geminivirus-encoded TrAP suppressor inhibits the histone methyltransferase SUVH4/KYP to counter host defense

    Claudia Castillo-González et al.
    A viral protein hijacks the key effector of transcriptional gene silencing, Su(var)3-9, to evade host plant surveillance.

    Multiple abiotic stimuli are integrated in the regulation of rice gene expression under field conditions

    Anne Plessis et al.
    Simple mathematical models can relate gene expression to climatic variables in field grown rice.

    Flotillin-mediated membrane fluidity controls peptidoglycan synthesis and MreB movement

    Aleksandra Zielińska et al.
    Correct cell wall synthesis in bacteria depends on flotillin-mediated membrane fluidity.
