Discrimination of phytochrome dependent light inducible from non-light inducible plant genes. Prediction of a common light-responsive element (LRE) in phytochrome dependent light inducible plant genes.
We aligned 14 5'-leading sequences of small subunit ribulose-1,5-bisphosphate carboxylase (rbcS) genes. A strong consensus sequence ("CCTTATCAT") was located directly upstream of the TATA-box. The occurrence of this motif in other light dependent phytochrome regulated plant genes led to the calculation of two consensus matrices. With these two matrices we are able to distinguish almost all known light induced plant genes which are phytochrome regulated from non-light induced plant genes indicating, that all these genes share a common light-responsive element (LRE). The results obtained by computer analysis are discussed with regard to experimental data.
