  2. 1. Drought Stress Signal Transduction by the HD-Zip Transcription Factors ATHB6 and ATHB7

    Author : Mattias Hjellström; Dorothea Bartels; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi; fysiologisk botanik; Physiological Botany;

    Abstract : This work describes the regulation of drought stress responses in Arabidopsis thaliana and adresses the roles of the homeodomain-leucine zipper (HD-Zip) transcription factors in this regulation. The characteristics of ATHB6 and ATHB7, two genes encoding class I HD-Zip transcription factors were analysed. READ MORE

  4. 2. 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.

  5. 3. 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

  6. 4. 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

  7. 5. Characterisation of Members of the HD-Zip I and DREB/ERF Transcription Factor Families and their Functions in Plant Stress Responses

    Author : Elin Övernäs; Peter Engström; Jaako Kangasjärvi; Uppsala universitet; []
    Keywords : Fysiologisk botanik; Physiological Botany;

    Abstract : Plants have to adapt to various environmental conditions. In comparison with other eukaryotes, plant genomes encode relatively many transcription factors, and have families of transcription factors only found in plants, two such are the large AP2/ERF (APETALA2/Ethylene Responsive Factor) and HD-Zip (Homeodomain leucine zipper) families.
