Abstract

The objective of this grant proposal is to test the hypothesis that sphingosine-1-phospate (SIP) is a novel signalling molecule in plants. To test this hypothesis we shall address the following questions: (a) Do SIP levels increase during drought? (b) If SIP levels increase during drought where does the SIP accumulate? (c) Does SIP have an intracellular site of action in guard cells? (d) Does the Arabidopsis sphingosine kinase gene (AtSPK) encode a functional sphingosine kinase and what are its kinetic properties? (e) Where in the plant is AtSPK expressed and is it stress regulated? (f) What is the in vivo function of the AtSPK gene?
