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

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

   Sammanfattning : 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. LÄS MER

3. 7. Functional characterization of the pointed cotyledon subclass of HDZip genes in Arabidopsis thaliana

   Författare :Johannes Hanson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

   Sammanfattning : Genes encoding homeodomain leucine zipper, HDZip, transcription factors constitute a large gene family in Arabidopsis thaliana. In this thesis the isolation and characterization of four HDZip genes (ATHB3, -13, -20 and -23) is described. These genes are similar in sequence and form a distinct subclass within the HDZip gene family. LÄS MER

4. 8. The Role of the Homeobox Gene ATHB16 in Development Regulation in Arabidopsis thaliana

   Författare :Yan Wang; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Arabidopsis thaliana; Homeobox gene; Functional genomics; Plant development; ATHB16; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

   Sammanfattning : There are 42 members of the homeodomain-leucine zipper (HDZip) family of transcription factors in Arabidopsis thaliana. This thesis focuses on the functional analysis of one member of this family, ATHB16, and on the biochemical properties of HDZip proteins. LÄS MER

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

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

   Sammanfattning : 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.

7. 10. Significance of hydrolytic enzymes expressed during xylem cell death

   Författare :Benjamin Bollhöner; Hannele Tuominen; Moritz Nowack; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Populus; xylem cell death; metacaspase; fiber; lateral root emergence; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik; molecular cell biology; molekylär cellbiologi;

   Sammanfattning : Xylem is an inherent feature of all vascular plants and functions in water transport and mechanical support. In order to efficiently transport water, xylem cells are reinforced by secondary walls before they undergo programmed cell death and their cell contents are removed by autolysis to create a hollow tube.
