Abstract/OtherAbstract:
The forkhead-associated (FHA) domain is involved in protein-protein interaction by recognizing a phosphothreonine epitope on target proteins. In this study, we investigated in planta functions of the Arabidopsis FHA domain 2. AtFHA2 was mainly localized in the nucleus. Arabidopsis fha2 null mutants grew normally during the vegetative stage, but had severely reduced fertility during reproductive stage. The reduced fertility was mainly caused by defective stamen filament elongation, while female flower parts of the mutants were fertile. Additionally, the mutants had fewer stamens than the wild type and the vegetative organs of the mutants, such as cotyledons and leaves, had increased ploidy. These results suggest that AtFHA2 may play a role in a signaling pathway for the control of plant organ development.
