The Peace-Athabasca Delta (PAD) receives a mixture of hydrocarbons from biogenic, pyrogenic, and petrogenic processes. Source apportionment in the PAD has focussed on polycyclic aromatic compounds (PACs), which are ubiquitous environment susceptible to weathering. In contrast, petroleum biomarkers terpanes, hopanes, steranes degradation-resistant organic found uniquely products that can identif...

Abstract Background Genome-wide change of polyadenylation (polyA) sites (also known as alternative polyadenylation, APA) is emerging an important strategy gene regulation in response to stress plants. But little woody perennials that are persistently dealing with multiple abiotic stresses. Results Here, we performed a genome-wide profiling under heat and cold treatments Populus trichocarpa . Th...
