2. 1. Metabolic engineering for production of complex lipids in tobacco (Nicotiana benthamiana) leaves and rice (Oryza sativa) endosperm

   Author : Selcuk Aslan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : World chemical and energy supplies for industry are today highly dependent on unsustainable fossil reserves. Vegetable lipids with similar chemical structures to fossil oil could be the ultimate renewable solution to replace fossil oil and provide environmentally friendly feedstocks and energy resources.

4. 2. Grain Yield and Quality Traits of Rice (Oryza sativa L.) Cultivars under Intermittent Drought and Contrasting Temperatures : physiological, biochemical and molecular characterisation

   Author : Alphonsine Mukamuhirwa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Rice (Oryza sativa) has evolved in a semi-aquatic tropical environment and therefore thrives better in a water intensive system and optimal temperature between 25 and 30°C. With the future climate change, frequent droughts and heat stress are predicted to happen simultaneously in field but little is known about their combined effects on rice productivity and quality.

5. 3. In the quest for a cold tolerant variety : gene expression profile analysis of cold stressed oat and rice

   Author : Angelica Lindlöf; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cold tolerance; oat; rice; bioinformatics analysis; Bioinformatics; Bioinformatik; Technology; Teknik; cold tolerance; oat; rice; bioinformatics analysis;

   Abstract : Cold acclimation is a process which increases the freezing tolerance of an organism, after exposure to low, non-freezing temperatures. The acclimation ensures that cold tolerant species can endure harsh winter conditions, by preparing them to sub-zero temperatures. READ MORE

6. 4. ARSENIC REMOVAL BY PHYTOFILTRATION AND SILICON TREATMENT : A POTENTIAL SOLUTION FOR LOWERING ARSENIC CONCENTRATIONS IN FOOD CROPS

   Author : Arifin Sandhi; Gunnar Jacks; Gunno Renman; Maria Greger; Roger Herbert; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aquatic moss; grain; rice; lettuce; macrophyte; phytoremediation; speciation; temperature; oxygenation; wetland.; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : Use of arsenic-rich groundwater for crop irrigation can increase the arsenic (As) content in food crops and act as a carcinogen, compromising human health. Using aquatic plant based phytofiltration is a potential eco-technique for removing arsenic from water. READ MORE

7. 5. Unravelling the complexity of cold acclimation in plants

   Author : Aakash Chawade; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; cold acclimation; winter; oat; arabidopsis; stress; freezing; genetic networks; metabolomics;

   Abstract : Many plants respond to low non-freezing temperatures by increasing their freezing tolerance in a process known as cold acclimation. Microarray studies have shown that hundreds of genes are differentially expressed during the cold acclimation process in Arabidopsis. READ MORE
