  1. 1. Chaperone/usher machinery : a catalyst of virulence organelle assembly

    Author : Xiaodi Yu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Many virulence organelles of Gram-negative bacterial pathogens are assembled via the periplasmic chaperone/usher (CU) pathway. The assembly process is a complex task, involving secretion of organelle subunits via the two membranes and periplasm, subunit folding and assembly. READ MORE

  2. 2. Synthesis of glucuronoxylan in higher and lower plants : is there conservation of the enzymatic machinery?

    Author : Emma Hörnblad; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The hemicellulose glucuronoxylan (GX) is the second most abundant polysaccharide after cellulose in the secondary cell walls of angiosperms and contributes significantly to the properties of wood as raw materials. Despite this, very little is known about the biosynthesis of hemicellulose. READ MORE

  3. 3. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Author : Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. READ MORE

  4. 4. Data driven crop disease modeling

    Author : Priyamvada Shankar; Marcus Liwicki; Foteini Liwicki; Lili Jiang; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Crop Disease Prediction; Precision Agriculture; Digital Farming; Artificial Intelligence; Machine learning; Maskininlärning; Machine Learning;

    Abstract : The concept of precision farming deals with the creation and use of data from machinery and sensors on and off the field to optimize resources and sustainably intensify food production to keep up with increasing demand. However, in the face of a growing amount of data being collected, smarter data processing and analysis techniques are needed and have prompted the evaluation and incorporation of artificial intelligence (AI) and machine learning (ML) techniques for multiple use cases right from seeding to harvesting.

  5. 5. Bioenergy from Swedish forests : A Study of extraction methods, quality and effects for forest owners

    Author : Daniel Nilsson; Johan Bergh; Peter Lerman; Gudmund Vollbrecht; Nasko Terziew; Linnéuniversitetet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES; logging residues; forest fuels; moisture content; needles; nutrients; moisture content measurements; Norway spruce; dry-stacking; fresh-stacking; Forestry and Wood Technology; Skog och träteknik;

    Abstract : The forest constitutes a very important element of renewable natural resources and makes a significant contribution to the Swedish bioeconomy. Biofuels are Sweden’s largest source of energy; of all the energy we use, 32% comes from biofuels, and of this approximately 85% comes from the forest and the forestry sector. READ MORE
