The SPOROCYTELESS gene of Arabidopsis is required for initiation of sporogenesis and encodes a novel nuclear protein.
The formation of haploid spores marks the initiation of the gametophytic phase of the life cycle of all vascular plants ranging from ferns to angiosperms. In angiosperms, this process is initiated by… Expand
TAPETUM DETERMINANT1 Is Required for Cell Specialization in the Arabidopsis Anther Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.016618.
In flowering plants, pollen formation depends on the differentiation and interaction of two cell types in the anther: the reproductive cells, called microsporocytes, and somatic cells that form the… Expand
Genetic and molecular identification of genes required for female gametophyte development and function in Arabidopsis
The plant life cycle involves an alternation of generations between sporophyte and gametophyte. Currently, the genes and pathways involved in gametophytic development and function in flowering plants… Expand
VANGUARD1 Encodes a Pectin Methylesterase That Enhances Pollen Tube Growth in the Arabidopsis Style and Transmitting Tract
In flowering plants, penetration of the pollen tube through stigma, style, and transmitting tract is essential for delivery of sperm nuclei to the egg cells embedded deeply within female tissues.… Expand

We have generated Dissociation (Ds) element insertions throughout the Arabidopsis genome as a means of random mutagenesis. Here, we present the molecular analysis of genomic sequences that flank the… Expand
Overexpression of TAPETUM DETERMINANT1 Alters the Cell Fates in the Arabidopsis Carpel and Tapetum via Genetic Interaction with EXCESS MICROSPOROCYTES1/EXTRA SPOROGENOUS CELLS1
Previously, we reported that the TAPETUM DETERMINANT1 (TPD1) gene is required for specialization of tapetal cells in the Arabidopsis (Arabidopsis thaliana) anther. The tpd1 mutant is phenotypically… Expand
Comparison of MADS box gene expression in developing male and female flowers of the dioecious plant white campion.
The MADS box motif is common to genes that regulate the pattern of flower development. To determine whether MADS box genes also play a role in differentiation of the sexes in dioecious plants, we… Expand
