SRP189393 PRJNA528983 RNA-seq reads from W22 silks pollinated by B73 pollen W22 reference silks were pollinated by B73 reference pollen in order to study the gene expression from pollen tubes. By using different genomes, we can distinguish (B73) pollen tube expression from (W22) silk expression in the pollinated silks. Maize Gametophyte Project http://maizegametophyte.org
