    • Arabidopsis late blight: Infection of a nonhost plant by $\textit{Albugo laibachii}$ enables full colonization by $\textit{Phytophthora infestans}$ 

      Belhaj, Khaoula; Cano, Liliana M; Prince, David C; Kemen, Ariane; Yoshida, Kentaro; Dagdas, Yasin F; Etherington, Graham J et al. (Wiley, 2016-06-15)
      The oomycete pathogen $\textit{Phytophthora infestans}$ causes potato late blight, and as a potato and tomato specialist pathogen, is seemingly poorly adapted to infect plants outside the Solanaceae. Here, we report the ...
    • Auxin Acts through MONOPTEROS to Regulate Plant Cell Polarity and Pattern Phyllotaxis 

      Bhatia, Neha; Bozorg, Behruz; Larsson, André; Ohno, Carolyn; Jönsson, Sten Henrik; Heisler, Marcus G (2016-11-03)
    • Auxin Signaling 

      Leyser, Henrietta Miriam
      Auxin acts as a general co-ordinator of plant growth and development, transferring information over both long and short ranges. Auxin famously appears to be extraordinarily multi-functional, with different cells responding ...
    • Biomartr: genomic data retrieval with R 

      Drost, Hajk-Georg; Paszkowski, J
      $\textbf{MOTIVATION}$: Retrieval and reproducible functional annotation of genomic data are crucial in biology. However, the current poor usability and transparency of retrieval methods hinders reproducibility. Here we ...
    • BRC1 expression regulates bud activation potential but is not necessary or sufficient for bud growth inhibition in $\textit{Arabidopsis}$ 

      Seale, M; Bennett, T; Leyser, Henrietta Miriam (The Company of Biologists, 2017-05-02)
      The degree of shoot branching in $\textit{Arabidopsis}$ is determined by the activation of axillary buds. Bud activity is regulated by diverse environmental and developmental signals, often mediated via plant hormones, ...
    • Cell size and growth regulation in the $\textit{Arabidopsis thaliana}$ apical stem cell niche 

      Willis, Lisa Anne; Refahi, Yassin; Wightman, Raymond; Landrein, Benoit Pierre; Teles, J; Huang, KC; Meyerowitz, EM et al. (National Academy of Sciences, 2016-12-20)
      Cell size and growth kinetics are fundamental cellular properties with important physiological implications. Classical studies on yeast, and recently on bacteria, have identified rules for cell size regulation in single ...
    • Cell type boundaries organize plant development 

      Caggiano, Monica Pia; Yu, Xiulian; Bhatia, Neha; Larsson, Andre; Ram, Hasthi; Ohno, Carolyn K; Sappl, Pia et al. (eLife Sciences Publications, 2017-09-12)
      In plants the dorsoventral boundary of leaves defines an axis of symmetry through the centre of the organ separating the top (dorsal) and bottom (ventral) tissues. Although the positioning of this boundary is critical for ...
    • Colonization of barley by the broad-host hemibiotrophic pathogen Phytophthora palmivora uncovers a leaf development dependent involvement of MLO 

      Le, Fevre Ruth; O’Boyle, Bridget; Moscou, Matthew J; Schornack, Sebastian (APS PRESS, 2016)
      The discovery of barley MLO demonstrated that filamentous pathogens rely on plant genes to achieve entry and lifecycle completion in barley leaves. Whilst having a dramatic effect on foliar pathogens, it is unclear whether ...
    • Companion cells: A diamond in the rough 

      Otero, S; Helariutta, Yrjo Eero; Turner, S (Oxford University Press, 2016-01-01)
      Vascular plants have developed highly specialized cells to transport nutrients and developmental signals. The differentiation process includes the degradation of multiple organelles of the sieve element cells (SEs) to ...
    • Conformal growth of $\textit{Arabidopsis}$ leaves 

      Mitchison, Graeme (Elsevier, 2016-08-16)
      I show that Arabidopsis leaf growth can be described with good precision by a conformal map, where expansion is locally isotropic (the same in all directions) but the amount of expansion can vary with position. Data obtained ...
    • Connective auxin transport in the shoot facilitates communication between shoot apices 

      Bennett, Tom; Hines, Geneviève; van, Rongen Martin; Waldie, Tanya; Sawchuk, Megan G; Scarpella, Enrico; Ljung, Karin et al. (PLOS, 2016-04-27)
      The bulk polar movement of the plant signaling molecule auxin through the stem is a long-recognized but poorly understood phenomenon. Here we show that the highly polar, high conductance polar auxin transport stream (PATS) ...
    • A continuous growth model for plant tissue 

      Bozorg, B; Krupinski, P; Jönsson, Sten Henrik (Institute of Physics, 2016-12-01)
      Morphogenesis in plants and animals involves large irreversible deformations. In plants, the response of the cell wall material to internal and external forces is determined by its mechanical properties. An appropriate ...
    • Cross-species functional diversity within the PIN auxin efflux protein family. 

      O'Connor, Devin Lee; Elton, Samuel; Ticchiarelli, Fabrizio; Hsia, Mon Mandy; Vogel, John P; Leyser, Henrietta Miriam (2017-10-24)
    • Cytokinin and auxin display distinct but interconnected distribution and signaling profiles to stimulate cambial activity 

      Immanen, Juha; Nieminen, Kaisa; Smolander, Olli-Pekka; Kojima, Mikiko; Serra, Juan Alonso; Koskinen, Patrik; Zhang, Jing et al. (Elsevier (Cell Press), 2016-07-14)
      Despite the crucial roles of phytohormones in plant development, comparison of the exact distribution profiles of different hormones within plant meristems has thus far remained scarce. Vascular cambium, a wide lateral ...
    • Cytosine methylation at CpCpG sites triggers accumulation of non-CpG methylation in gene bodies 

      Zabet, NR; Catoni, Marco; Prischi, F; Paszkowski, Jerzy Waclaw
      Methylation of cytosine is an epigenetic mark involved in the regulation of transcription, usually associated with transcriptional repression. In mammals, methylated cytosines are found predominantly in CpGs but in plants ...
    • Developmental Restriction of Retrotransposition Activated in Arabidopsis by Environmental Stress 

      Gaubert, H; Sanchez, DH; Drost, Hajk-Georg; Paszkowski, Jerzy Waclaw (Genetics Society of America, 2017-10-01)
      Retrotransposons (RTs) may rapidly increase in copy number due to periodic bursts of transposition. Such bursts are mutagenic and thus potentially deleterious. However, certain transposition-induced gain-of-function or ...
    • Different reprogramming propensities in plants and mammals: Are small variations in the core network wirings responsible? 

      Olariu, V; Nilsson, J; Jönsson, Sten Henrik; Peterson, C (Public Library of Science, 2017-04-06)
      Although the plant and animal kingdoms were separated more than 1,6 billion years ago, multicellular development is for both guided by similar transcriptional, epigenetic and posttranscriptional machinery. One may ask to ...
    • DNA sequence properties that predict susceptibility to epiallelic switching. 

      Catoni, Marco; Griffiths, J; Becker, C; Zabet, NR; Bayon, C; Dapp, M; Lieberman-Lazarovich, M et al. (Nature Publishing Group, 2017-03-01)
      Transgenerationally heritable epialleles are defined by the stable propagation of alternative transcriptional states through mitotic and meiotic cell cycles. Given that the propagation of DNA methylation at CpG sites, ...
    • Emergent Patterns from Probabilistic Generalisations of Lateral Activation and Inhibition 

      Willis, Lisa; Kabla, Alexandre Joseph (The Royal Society Publishing, 2016-05-11)
      The combination of laterally activating and inhibiting feedbacks is well known to spontaneously generate spatial organisation. It was introduced by Gierer and Meinhardt as an extension of Turing’s great insight, that two ...
    • An epidermis-driven mechanism positions and scales stem cell niches in plants 

      Gruel, Jérémy; Landrein, Benoit Pierre; Tarr, Paul; Schuster, Christoph; Refahi, Yassin; Sampathkumar, Arun; Hamant, Olivier et al. (American Association for the Advancement of Science, 2016-01-21)
      How molecular patterning scales to organ size is highly debated in developmental biology. We explore this question for the characteristic gene expression domains of the plant stem cell niche residing in the shoot apical ...
