Molecular characterization of TaSTOP1 homoeologues and their response to aluminium and proton (H(+)) toxicity in bread wheat (Triticum aestivum L.).

ABSTRACT:

Background

Aluminium (Al) toxicity is considered to be one of the major constraints affecting crop productivity on acid soils. Being a trait governed by multiple genes, the identification and characterization of novel transcription factors (TFs) regulating the expression of entire response networks is a very promising approach. Therefore, the aim of the present study was to clone, localize, and characterize the TaSTOP1 gene, which belongs to the zinc finger family (Cys2His2 type) transcription factor, at molecular level in bread wheat.

Results

TaSTOP1 loci were cloned and localized on the long arm of homoeologous group 3 chromosomes [3AL (TaSTOP1-A), 3BL (TaSTOP1-B) and 3DL (TaSTOP1-D)] in bread wheat. TaSTOP1 showed four potential zinc finger domains and the homoeologue TaS
