Understanding how cellular metabolism works and is regulated requires that the underlying biochemical pathways be adequately represented and integrated with large metabolomic data sets to establish a robust network model. Genetically engineering energy crops to be less recalcitrant to saccharification requires detailed knowledge of plant polysaccharide structures and a thorough understanding of...

Fine-tuned and coordinated regulation of transport, metabolism and redox homeostasis allows plants to acclimate to osmotic and ionic stress caused by high salinity. Sugar beet is a highly salt tolerant crop plant and is therefore an interesting model to study sodium chloride (NaCl) acclimation in crops. Sugar beet plants were subjected to a final level of 300 mM NaCl for up to 14 d in hydroponi...

BACKGROUND AND AIMS In crops other than sugarcane there is good evidence that the size and activity of carbon sinks influence source activity via sugar-related regulation of the enzymes of photosynthesis, an effect that is partly mediated through coarse regulation of gene expression. METHODS In the current study, leaf shading treatments were used to perturb the source-sink balance in 12-month...

Plant parasitic nematodes, Meloidogyne javanica in particular, cause significant yield losses in sugarcane crops in South Africa. The chemicals at present available for nematode control are expensive and potentially detrimental to the environment. It has been reported that various types of crops reduce the numbers of plant parasitic nematodes. Seven green manure crops (sunn hemp, marigold, oats...

introduction intercropping plays an important role in agriculture because of beneficial interactions. intercropping of legumes and cereals is an old practice in tropical agriculture dating back to ancient civilization. cereals and other plant intercrops could substantially increase forage quantity and quality and decrease the requirement for protein supplements. intercropping of cereals and oth...

Enhancing Productivity is one of three research programs within the Cooperative Research Centre for Sustainable Sugar Production (CRC Sugar). The program was established to undertake research and education to improve the profitability and international competitiveness of the Australian sugar industry through the development and adoption of novel management practices across the raw sugar industr...

Lignocellulosic biomass such as agricultural and forestry residues and dedicated crops provides a low-cost and uniquely sustainable resource for production of many organic fuels and chemicals that can reduce greenhouse gas emissions, enhance energy security, improve the economy, dispose of problematic solid wastes, and improve air quality. A technoeconomic analysis of biologically processing li...

Habitat diversification can potentially benefit natural enemies by providing alternative prey, a suitable microclimate, or nectar and pollen (Landis et al., 2000). Laboratory and field cage studies demonstrate that parasitoids with access to sugar have greater longevity, fecundity, and more femalebiased sex ratios than starved parasitoids (Idris and Grafius, 1995; Dyer and Landis, 1996; Berndt ...

Molecular markers are a highly valuable tool for creating genetic maps. Like in many other crops, sugar beet (Beta vulgaris L.) breeding is increasingly supported by the application of such genetic markers. Single nucleotide polymorphism (SNP) based markers have a high potential for automated analysis and high-throughput genotyping. We developed a bioinformatics workflow that uses Sanger and 2n...

Sorghum is one of the most promising bioenergy crops. Stem juice yield, together with stem sugar concentration, determines sugar yield in sweet sorghum. Bulked segregant analysis (BSA) is a gene mapping technique for identifying genomic regions containing genetic loci affecting a trait of interest that when combined with deep sequencing could effectively accelerate the gene mapping process. In ...
