Isolation of Phytochrome B Photobodies.
Methods in molecular biology (Clifton, N.J.)(2024)
摘要
Phytochrome B (phyB), a plant photoreceptor, forms a membraneless organelle known as a photobody. Here, we present a protocol for the isolation of phyB photobodies through fluorescence-activated particle sorting from mature transgenic Arabidopsis leaves expressing phyB-GFP. This protocol involves the isolation of nuclei from frozen ground leaves using sucrose gradient centrifugation, the disruption of nuclear envelopes by sonication, and the subsequent isolation of phyB photobodies through fluorescence-activated particle sorting. We include experimental tips and notes for each step.
