Comments

construct_comment: "ptwi(a)-CAT" is a generic symbol for a series of twi(antisense)-CAT fusion constructs; used to characterize twi 5\' regulatory elements and their interactions with the dorsal protein, using a cell culture assay. See descriptions under "Associated alleles."

(Thisse et al., 1991)

report comment: twi fragment in orientation opposite of that in wildtype sequence, relative to direction of transcription.
