2. 1. Plant Calreticulins -Calcium-binding proteins with many functions

   Author : Anna Christensen; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tobacco; plant; calreticulin; isoforms; Arabidopsis; localization; mouse embryonic fibroblasts;

   Abstract : Endoplasmic reticulum (ER) plays an important role in protein synthesis, folding, maturation and transport of newly synthesized proteins, as well as the regulation of cellular Ca2+ homeostasis. A protein that is involved in several of these functions in the ER is calreticulin (CRT), which is a Ca2+-binding chaperone that resides in the lumen of the ER. READ MORE

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

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

   Abstract : 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). READ MORE

5. 3. FtsH metalloproteases and their pseudo-proteases in the chloroplast envelope of Arabidopsis thaliana

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis thaliana; AAA-ATPases; abscisic acid; chloroplast; drought; embryo-lethal; FtsH metalloprotease; intrinsic water-use efficiency WUEi ; leaf variegation; outdoor conditions; oxidative stress; plastid biogenesis; proteomics; protein import; root-associated bacterial communities seedlings; Biochemistry; biokemi; molekylärbiologi; Molecular Biology; biology; biologi;

   Abstract : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. READ MORE

6. 4. Controlled auxin biosynthesis and transport are important for developmental decisions in the early diverging land plant Physcomitrella patens

   Author : Eric Pederson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The aim of this thesis was to increase our understanding of the importance of the plant hormone auxin in land plant evolution. The role of a number of auxin regulatory network components in developmental decisions during the haploid phase of the life cycle of the model moss Physcomitrella patens, which belongs to the early diverging bryophyte group of land plants, was investigated.

7. 5. Developmental phase transitions in Norway spruce : a molecular approach to identify regulatory mechanisms

   Author : Daniel Uddenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Plant development proceeds through distinct phases that are controlled by complex networks of regulatory genetic circuits and fine-tuned by environmental and endogenous cues. Many of these regulatory networks have been unraveled in annual and perennial angiosperms, while they remain predominantly unknown in ecologically and economically important gymnosperm species such as the conifers.
