Title

The Subtilisin-Like Serine Protease SDD1 Mediates Cell-to-Cell Signaling during Arabidopsis Stomatal Development

Uritza von Groll; Dieter Berger; Thomas Altmann The Plant Cell 2002. doi:10.1105/tpc.001016

Other claims from this paper (9)

Intervention effect The sdd1-1 mutation caused stomatal clustering.
Intervention effect The sdd1-1 mutation increased stomatal density twofold to fourfold.
Observation SDD1 expression was strong in stomatal precursor cells.
Mechanism Feedback negatively controlled the SDD1 promoter.
Observation The SDD1 protein was exported to the apoplast and probably associated with the plasma membrane.
Intervention effect SDD1 overexpression decreased stomatal density twofold to threefold.
Observation SDD1 overexpression was effective in flp but tmm acted epistatically.
Mechanism The authors propose that SDD1 generates an extracellular signal from stomatal precursor cells.
Mechanism SDD1 function depended on TMM activity.
