Previous research showed that levels of the flavonol quercetin (Q) were positively associated with UV stress resistance in populations of white clover (Trifolium repens L.), and inversely linked to dry matter (DM) production (Hofmann et al, 2000). Q, and to a lesser degree its precursor kaempferol (K), have been implicated as antioxidants and energy dissipating compounds in plants exposed to stress, and could be useful markers for resistance to other stress factors. This study used a novel white clover hybrid of the productive cultivar Kopu II and of the stress-resistant population Tienshan to examine whether these relationships also hold under drought on a genotype level for germplasm development in future breeding trials.
Despite the developments in conventional PCR, the complexity of multiplex Real Time PCR is still limited due to the lack of sufficient detection channels. To achieve high-end multiplexing capacity on standard Real Time PCR machines, Anapa Biotech has developed the MeltPlex® technology (see box on right).READ MORE
Genome-wide association studies (GWAS) have identified more than 100 genetic loci associated with type 2 diabetes. The majority of these are located in the intergenic or intragenic regions suggesting that the implicated variants may alter chromatin conformation. This, in turn, is likely to influence the expression of nearby or more remotely located genes to alter beta cell function. At present, however, detailed molecular and functional analyses are still lacking for most of these variants. We recently analysed one of these loci and mapped five causal variants in an islet-specific enhancer cluster within the STARD10 gene locus. Here, we aimed to understand how these causal variants influence b-cell function by alteration of the chromatin structure of enhancer clusterREAD MORE
Early life stress (ELS) is highly associated with development of psychopathology
and mood disorders in adulthood. Genetic studies have identified variation in the gene calcium voltage-gated channel subunit alpha1C (CACNA1C) to increase risk for several psychiatric disorders. This poster assessed the expression of Cacna1c following prepubertal stress.
