Genome-wide association studies are a powerful approach for identifying genes related to complex traits in organisms, but limited by the requirement reference genome sequence of species under study. To circumvent this problem, we propose transcriptome-referenced study (TRAS) that utilizes transcriptome generated single-molecule long-read sequencing as score population variation at both transcript and expression levels. Candidate transcripts identified when scores associated with trait their...

Three-dimensional structured illumination microscopy (3D-SIM) provides excellent optical sectioning and doubles the resolution in all dimensions compared with wide-field microscopy. However, its much lower axial results blurred fine details that direction overall image distortion. Here we present 4Pi-SIM, a substantial revamp of I5S synergizes 3D-SIM interferometric to achieve isotropic through interference both detection wavefronts. We evaluate performance 4Pi-SIM by imaging various...
