Temperature Responses

Expression pattern of cold induced genes in Phalaenopsis amabilis.

Changes in environmental temperature activate the expression of genes that respond to stress and help plants to maintain cellular function. Genes in P. amabilis possibly associate with the low temperature induction were isolated using the PCR-select cDNA subtraction method. Cold stress induced multiple regulatory pathways in plants. Our database contains ESTs encoding Myb transcription factors, F-box family protein, and zinc finger proteins that may function as regulators in the stress-induced signal transduction pathways. To profile the transcriptional changes of these genes, real-time PCR was performed. Our data suggest that the orchid genes coding for a protein kinase, a heat shock cognate 70 kDa protein and a catalase may contribute to cold stress tolerance.
