  • Gibberellin signaling.

    Lynn M Hartweck · Planta · 2008

    This review covers recent advances in gibberellin (GA) signaling. GA signaling is now understood to hinge on DELLA proteins. DELLAs negatively regulate GA response by activating the promoters of several genes including Xerico, which upregulates the abscisic acid pathway which is antagonistic to GA. DELLAs also promote transcription of the GA receptor, GIBBERELLIN INSENSITIVE DWARF 1 (GID1) and ind…

  • Emerging and evolving concepts in gene essentiality.

    Giulia Rancati, Jason Moffat, Athanasios Typas 他 · Nature reviews. Genetics · 2018

    Gene essentiality is a founding concept of genetics with important implications in both fundamental and applied research. Multiple screens have been performed over the years in bacteria, yeasts, animals and more recently in human cells to identify essential genes. A mounting body of evidence suggests that gene essentiality, rather than being a static and binary property, is both context dependent …

  • Evo-devo and an expanding evolutionary synthesis: a genetic theory of morphological evolution.

    Sean B Carroll · Cell · 2008

    Biologists have long sought to understand which genes and what kinds of changes in their sequences are responsible for the evolution of morphological diversity. Here, I outline eight principles derived from molecular and evolutionary developmental biology and review recent studies of species divergence that have led to a genetic theory of morphological evolution, which states that (1) form evolves…

  • The developmental-genetics of canalization.

    Benedikt Hallgrimsson, Rebecca M Green, David C Katz 他 · Seminars in cell & developmental biology · 2019

    Canalization, or robustness to genetic or environmental perturbations, is fundamental to complex organisms. While there is strong evidence for canalization as an evolved property that varies among genotypes, the developmental and genetic mechanisms that produce this phenomenon are very poorly understood. For evolutionary biology, understanding how canalization arises is important because, by modul…

  • Maternal-fetal conflict, genomic imprinting and mammalian vulnerabilities to cancer.

    David Haig · Philosophical transactions of the Royal Society of London. Series B, Biological sciences · 2015

    Antagonistic coevolution between maternal and fetal genes, and between maternally and paternally derived genes may have increased mammalian vulnerability to cancer. Placental trophoblast has evolved to invade maternal tissues and evade structural and immunological constraints on its invasion. These adaptations can be co-opted by cancer in intrasomatic selection. Imprinted genes of maternal and pat…

  • Evolution of phenotypic fluctuation under host-parasite interactions.

    Naoto Nishiura, Kunihiko Kaneko · PLoS computational biology · 2021

    Robustness and plasticity are essential features that allow biological systems to cope with complex and variable environments. In a constant environment, robustness, i.e., insensitivity of phenotypes, is expected to increase, whereas plasticity, i.e., the changeability of phenotypes, tends to diminish. Under a variable environment, existence of plasticity will be relevant. The robustness and plast…

  • Genomic and phenotypic characterization of antimicrobial resistance in clinical Nocardia species isolates.

    Ziyu Song, Bingqian Du, Min Yuan 他 · Frontiers in cellular and infection microbiology · 2025

    Antimicrobial resistance is prevalent across Nocardia species, with varying resistance profiles among different species, which poses significant challenges to effective treatment strategies. Our study aimed to assess the antimicrobial susceptibility profiles of various Nocardia species and investigate the potential correlation between resistance phenotypes and their underlying genotypes. This stud…

  • An overview of MYC and its interactome.

    Maralice Conacci-Sorrell, Lisa McFerrin, Robert N Eisenman 他 · Cold Spring Harbor perspectives in medicine · 2014

    This review is intended to provide a broad outline of the biological and molecular functions of MYC as well as of the larger protein network within which MYC operates. We present a view of MYC as a sensor that integrates multiple cellular signals to mediate a broad transcriptional response controlling many aspects of cell behavior. We also describe the larger transcriptional network linked to MYC …

  • Evolutionary Remodeling of Bacterial Motility Checkpoint Control.

    Bin Ni, Bhaswar Ghosh, Ferencz S Paldy 他 · Cell reports · 2017

    Regulatory networks play a central role in the relationship between genotype and phenotype in all organisms. However, the mechanisms that underpin the evolutionary plasticity of these networks remain poorly understood. Here, we used experimental selection for enhanced bacterial motility in a porous environment to explore the adaptability of one of the most complex networks known in bacteria. We fo…

  • Evolutionary dynamics of gene regulation.

    Douglas H Erwin · Current topics in developmental biology · 2020

    The long controversy over the importance of changes in the regulatory genome has been resolved with the recognition that such changes are a fundamental component of evolutionary dynamics. Comparative studies have revealed four dominant modes of change as the regulatory genome evolved: (1) the origin of regulatory novelties such as distal enhancers and new types of promoters at the origin of Metazo…
