Overexpression of AtAHL20 causes delayed flowering in Arabidopsis via repression of FT expression.

ABSTRACT:

Background

The 29-member Arabidopsis AHL gene family is classified into three main classes based on nucleotide and protein sequence evolutionary differences. These differences include the presence or absence of introns, type and/or number of conserved AT-hook and PPC domains. AHL gene family members are divided into two phylogenetic clades, Clade-A and Clade-B. A majority of the 29 members remain functionally uncharacterized. Furthermore, the biological significance of the DNA and peptide sequence diversity, observed in the conserved motifs and domains found in the different AHL types, is a subject area that remains largely unexplored.

Results

Transgenic plants overexpressing AtAHL20 flowered later than the wild type under both short and long days. Transcript accumulation an
