Homologous domain leucine zipper transcription factors (HDZip TFs) are considered to be morphogenetic regulators in response to environmental stimuli and plant development programs. Tahdzipi-1 is isolated from the liquid portion of endosperm of 3-6 DAP using Y1H system and the synthetic cis-element caat (G/C)ATTG- as bait (Lopato et al., Plant Methods. 2:3, 2006). It belongs to the second subfamily of HDZip tf. Q-PCR analysis detected very low levels of TahdZIPI-1 transcripts in all wheat tissues. All data obtained to date suggest that TahdziPI-1 is involved in the regulation of cell elongation by negatively regulating secondary cell wall biosynthesis.
