In a previous review of male gametophyte development (McCormick, 1993), it was noted that
the two areas posed by Mascarenhas (1975) as fruitful areas for future research were the …

▪ Abstract The Arabidopsis genome sequence has revealed that plants contain a much
larger complement of receptor kinase genes than other organisms. Early analysis of these …

A long-term goal of Arabidopsis research is to define the minimal gene set needed to
produce a viable plant with a normal phenotype under diverse conditions. This will require …

Cell differentiation is essential for the development of multicellular organisms. In flowering
plants, the haploid male gametophytes (pollen grains) are generated in the anther from …

Many flowering plants have adopted self-incompatibility mechanisms to prevent inbreeding
and promote out-crosses. In the Solanaceae, Rosaceae and Scrophulariaceae, two …

Sexual reproduction in many angiosperm plants involves self-incompatibility (SI), which is
one of the most important mechanisms to prevent inbreeding. SI is genetically controlled by …

Although pollen tube growth is essential for plant fertilization and reproductive success, the
regulators of the actin-related growth machinery and the cytosolic Ca2+ gradient thought to …

Petunia inflata S-locus F-box (Pi SLF) is thought to function as a typical F-box protein in
ubiquitin-mediated protein degradation and, along with Skp1, Cullin-1, and Rbx1, could …

Complex animals use a wide variety of adaptor proteins to produce specialized sites of
interaction between actin and membranes. Plants do not have these protein families, yet …

The pollen‐specific receptor kinases LePRK1 and LePRK2 have localization and
expression profiles that strongly suggest they play roles in pollen germination and tube …
