2. 1. Combining Metabolic Engineering and Synthetic Biology Approaches for the Production of Abscisic Acid in Yeast

   Author : Maximilian Otto; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; Botrytis cinerea; cell factory; abscisic acid; synthetic biology; biosensor; sesquiterpenoid; standardization; Saccharomyces cerevisiae;

   Abstract : Nature presents us with a myriad of complex and diverse molecules. Many of these molecules prove to be useful to humans and find applications as pharmaceuticals, biofuels, agrochemicals, cosmetic ingredients or food additives. One highly promising natural product with a broad range of potential applications is the terpenoid abscisic acid (ABA). READ MORE

4. 2. Analysis of plant growth regulating substances

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant regulators; phytohormones; pine; spruce; anther; abscisic acid; 3-indoleacetic acid; gibberellin Ag; N- 3-indoleacetyl -aspartic acid; dichlorophene; Amberlite XAD-7; identification; quantification; GC; HPLC; GC-MS; GC-MID; Hormoner;

   Abstract : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. READ MORE

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

   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. Cellular mechanisms of plant regeneration

   Author : Theodore Serivichyaswat; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Plants are remarkable at healing. Humankind has long known about this and has exploited it by grafting different plants together for crop propagation and crop improvement. During graft formation, the surfaces of the cut tissues attach, the cells proliferate, and the vasculatures reconnect to form a chimeric plant. READ MORE

7. 5. 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
