Genetic studies of embryo, ovule and flower development in Arabidopsis thaliana have led to
the independent isolation of different mutant alleles of a single gene (SIN1/SUS1/CAF, now …

The Arabidopsis genome encodes four Dicer-like (DCL) proteins, two of which contain putative
nuclear localization signals. This suggests one or more nuclear pathways for processing …

Apomixis, the clonal formation of seeds, is a rare yet widely distributed trait in flowering
plants. We have isolated the PARTHENOGENESIS (PAR) gene from apomictic dandelion that …

The importance of maternal cells in controlling early embryogenesis is well understood in
animal development, yet in plants the precise role of maternal cells in embryogenesis is …

The screening of enhancer detector lines in Arabidopsis thaliana has identified genes that
are specifically expressed in the sporophytic tissue of the ovule. One such gene is the MADS‐…

Expression of the viral silencing suppressor P1/HC-Pro in plants causes severe developmental
anomalies accompanied by defects in both short interfering RNA (siRNA) and microRNA …

Apomixis in the common dandelion (Taraxacum officinale) consists of three developmental
components: diplospory (apomeiosis), parthenogenesis, and autonomous endosperm …

Introduction of apomixis, asexual reproduction through seeds, into crop species has the
potential to dramatically transform plant breeding. A new study demonstrates that traits can be …

Screening enhancer detector lines has identified genes that are specifically expressed in
the diploid maternal sporophytic tissue of the ovule. One such gene is the MADS-box …

The ubiquity and importance of short duplex RNAs, termed microRNA (miRNA), for normal
development in higher eukaryotes are becoming increasingly clear. We had previously …
