The current challenge, now that two plant genomes have been sequenced, is to assign a
function to the increasing number of predicted genes. In Arabidopsis, approximately 55% of …

The gametophytic maternal effect mutant medea(mea) shows aberrant growth regulation
during embryogenesis in Arabidopsis thaliana. Embryos derived from meaeggs grow …

The communication of changes in the extracellular matrix to the interior of the cell is crucial
for a cell’s function. The extracellular peptides of the RAPID ALKALINIZATION FACTOR (…

The evolution of land flora transformed the terrestrial environment. Land plants evolved from
an ancestral charophycean alga from which they inherited developmental, biochemical, and …

that the mutant produced roots that were indistinguishable from wild-type roots when grown
in soil, in a different brand of agar, or in extensively washed Bacto agar, suggesting that the …

We report here the isolation of the Arabidopsis SOMATIC EMBRYOGENESIS RECEPTOR-LIKE
KINASE 1 (AtSERK1) gene and we demonstrate its role during establishment of somatic …

Directional transport of the phytohormone auxin is required for the establishment and
maintenance of plant polarity, but the underlying molecular mechanisms have not been fully …

In flowering plants, signaling between the male pollen tube and the synergid cells of the
female gametophyte is required for fertilization. In the Arabidopsis thaliana mutant feronia (fer), …

We generated and characterized greater than 500 Drosophila strains that carry single
copies of a novel P-element enhancer detector. In the majority of the strains, the beta-…

The term apomixis encompasses a suite of processes whereby seeds form asexually in plants.
In contrast to sexual reproduction, seedlings arising from apomixis retain the genotype of …
