WebExperimental evidence indicates that the chromatin filament is self-organized into a multilayer planar structure that is densely stacked in metaphase and unstacked in interphase. This chromatin organization is unexpected, but it is shown that diverse supramolecular assemblies, including dinoflagellate chromosomes, are multilayered. WebFeb 20, 2024 · Chromatin immunoprecipitation-quantitative PCR analyses further show that ARID5 is recruited to the chromatin of JA biosynthesis genes. Importantly, exogenous JA treatments can fully rescue the defects of stamen filament elongation in both arid5 and rlt mutants, leading to the partial recovery of fertility. Our results provide a clue how JA ...
