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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Frauke Augstein; Annelie Carlsbecker; Eva Sundberg; Charles Melnyk; Malcolm Bennett; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. HDZip I Transcription Factors in Arabidopsis thaliana : Expression and Function in Relation to Environmental Stress Conditions

    Författare :Anna S. B. Olsson; Peter Engström; Eva Söderman; Pieter B. F. Ouwerkerk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; homeodomain leucine zipper; ABA; transcription factor; water deficit; Arabidopsis thaliana; Biologi; Biology; Biologi;

    Sammanfattning : The homeodomain leucine zipper (HDZip) proteins constitute a plant-specific family of transcription factors, that based on sequence criteria have been grouped into four classes, HDZip I-IV. This thesis describes the phylogeny, function, expression patterns and regulation of the HDZip class I genes in the model species Arabidopsis thaliana. LÄS MER

  7. 5. Studies on the regulation of the Napin napA promoter by ABI3, bZIP and bHLH transcription factors

    Författare :Nathalie Martin; Lars Rask; Ines Ezcurra; Olof Olsson; Uppsala universitet; []
    Nyckelord :Molecular biology; transcription gene regulation; plant seed maturation; seed storage protein; ABA; ABI3; bZIP; bHLH; Brassica napus; Molekylärbiologi;

    Sammanfattning : The B3-domain transcription factor ABI3 is a major regulator of gene expression of seed maturation during Arabidopsis embryogenesis. The napA gene encodes for a Brassica napus 2S storage protein specifically expressed in the embryo during the early and mid-maturation phase (MAT program). LÄS MER
