Sh2 Transcripts in Various Maize Tissues.
Tissues were harvested from sibling plants containing only the HS33/Rev6 Sh2 transgene, only the functional Sh2 allele, or lacking a transcriptionally active Sh2 allele and were monitored via PCR for Sh2 transcript. The mutant sh2 allele, sh2-R, contains a large insertion giving rise to no detectable transcript. Silk and leaf tissue were harvested at flowering.
