  1. 1. Cell-to-Cell Signalling in Arabidopsis Root Development

    Author : Christina Joy Roberts; Annelie Carlsbecker; Dolf Weijers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HD-ZIP III; miRNA; plasmodesmata; auxin; ROS; xylem; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : Development in multicellular organisms requires a strict balance between cell division and differentiation. The simple architecture of the Arabidopsis thaliana root makes it an ideal model for studying molecular mechanisms controlling both the transition from cell division to cell differentiation and cell fate determination.

  2. 2. Mechanisms of plant root xylem developmental plasticity in response to water deficiency and salt

    Author : Frauke Augstein; Annelie Carlsbecker; Eva Sundberg; Charles Melnyk; Malcolm Bennett; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ABA; developmental plasticity; GA; HD-ZIP III; VND; xylem; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : Plants may be exposed to a variety of different environmental conditions including water deficiency and salt, both affecting the uptake of water into the plant. Water is taken up from the soil by the roots and distributed throughout the plant via the water conducting tissue, the xylem. READ MORE

  3. 3. Epigenetic Regulation of Light and Hormonal Signaling in Arabidopsis thaliana

    Author : Kristina Rizzardi; Annika Sundås-Larsson; Katarina Landberg; Johan Memelink; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TERMINAL FLOWER2; auxin; jasmonate; epigenetics; photomorphogenesis; Plant physiology; Växtfysiologi; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : Plants are stationary and need to adapt to the environment they live in. Integration of environmental cues, such as changes in light and temperature, can occur either directly or through the action of hormones. Hormone and light signaling leads to rapid changes in gene expression, and eventually changes in protein levels. READ MORE

  4. 4. Functional Diversification among MADS-Box Genes and the Evolution of Conifer Seed Cone Development

    Author : Erika Groth; Peter Engström; Karolina Tandre; Tom Gerats; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conifer; seed cone; evo-devo; morphology; plant development; plant evolution; gene family; gene evolution; AGAMOUS; MADS-box; transcription factor; Picea; Cryptomeria; Thujopsis; Juniperus; Biology; Biologi; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : MADS-box genes are important regulators of reproductive development in seed plants, including both flowering plants and conifers. In this thesis the evolution of the AGAMOUS subfamily of MADS-box genes, and what the ancestral function of this group of genes might have been in the early seed plants about 300 million years ago, was addressed by the discovery of two novel conifer genes, both basal to all previously known AGAMOUS subfamily genes.

  5. 5. Stelar Performance Under Drought : Regulation of Developmental Robustness and Plasticity of the Arabidopsis Root Xylem

    Author : Prashanth Ramachandran; Annelie Carlsbecker; Ari Pekka Mähönen; Uppsala universitet; []
    Keywords : HD-ZIP III TFs; miR165; Xylem; ABA; VND; plasticity; water deficit; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : Plants have evolved genetic mechanisms to sense, modulate and modify developmental programs in response to the changing environment. This brings forth challenges in stably generating tissue patterns while simultaneously allowing amenability. READ MORE
