Elucidation of the serosal cuticle machinery in the beetle Tribolium by RNA sequencing and functional analysis of Knickkopf1, Retroactive and Laccase2.

Chris G C Jacobs et al.

Insect biochemistry and molecular biology, 60, 7-12 (2015-03-10)

Insects have been extraordinary successful in colonizing terrestrial habitats and this success is partly due to a protective cuticle that mainly contains chitin and proteins. The cuticle has been well studied in larvae and adults, but little attention has been

Models for liquid-liquid partition in the system propylene carbonate-organic solvent and their use for estimating descriptors for organic compounds.

Thushara Karunasekara et al.

Journal of chromatography. A, 1218(6), 809-816 (2011-01-07)

Partition coefficients for varied compounds were determined for the organic solvent-propylene carbonate biphasic partition system where the organic solvent is n-heptane, isopentyl ether or 1-octanol. These partition coefficient databases are analyzed using the solvation parameter model facilitating a quantitative comparison

Genome-wide association mapping and biochemical markers reveal that seed ageing and longevity are intricately affected by genetic background and developmental and environmental conditions in barley.

Manuela Nagel et al.

Plant, cell & environment, 38(6), 1011-1022 (2014-10-21)

Globally, over 7.4 million accessions of crop seeds are stored in gene banks, and conservation of genotypic variation is pivotal for breeding. We combined genetic and biochemical approaches to obtain a broad overview of factors that influence seed storability and
