• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.

• Subcellular Localization: GFP:: COSA-1 is detected as a diffuse nucleoplasmic signal beginning in early pachytene and then displays a striking localization pattern later in pachytene that is consistent with expectations for a protein that marks crossover (CO) sites. Starting at the transition from mid to late pachytene and persisting through diplotene, GFP::COSA-1 localizes to 6.0 ± 0.2 bright foci per nucleus (n = 76), corresponding in number to the six COs - one per chromosome pair - that form during wild-type meiosis. At diplotene, GFP::COSA-1 localizes at the site of the single emerging chiasma on each homolog pair. We conclude that COSA-1 localizes to CO sites.
