The HECATE genes regulate female reproductive tract development in Arabidopsis thaliana.

Successful fertilization in plants requires the properly coordinated development of female reproductive tissues, including stigma, style, septum and transmitting tract. We have identified three closely related genes, HECATE1 (HEC1), HECATE2 (HEC2) and HECATE3 (HEC3), the expression domains of which encompass these regions of the Arabidopsis gynoecium. The HEC genes encode putative basic helix-l...

AtPV42a and AtPV42b Redundantly Regulate Reproductive Development in Arabidopsis thaliana

BACKGROUND The conserved SNF1/AMPK/SnRK1 complexes are global regulators of metabolic responses in eukaryotes and play a key role in the control of energy balance. Although α-type subunits of the SnRK1 complex have been characterized in several plant species, the biological function of β-type and γ-type subunits remains largely unknown. Here, we characterized AtPV42a and AtPV42b, the two homolo...

Arabidopsis HECATE genes function in phytohormone control during gynoecium development

The fruit, which develops from the fertilised gynoecium formed in the innermost whorl of the flower, is the reproductive organ and one of the most complex structures of an angiosperm plant. Phytohormones play important roles during flower and fruit patterning, morphogenesis and growth, and there is emerging evidence for a cross-talk between different classes of plant hormones throughout these p...

HALF FILLED promotes reproductive tract development and fertilization efficiency in Arabidopsis thaliana.

Successful fertilization in angiosperms requires the growth of pollen tubes through the female reproductive tract as they seek out unfertilized ovules. In Arabidopsis, the reproductive tract begins with the stigma, where pollen grains initially adhere, and extends through the transmitting tract of the style and ovary. In wild-type plants, cells within the transmitting tract produce a rich extra...

Comparative female reproductive tract development and morphology

A brief description of the basic pattern of mammalian organogenesis of the female reproductive tract is presented based on events as they occur in human beings. The emphasis is not on the details of this development, but rather its organization and timing. Tables of comparative development provide a comparison of similar events between man, rat, mouse, and chick.
