Abstract
Abstract Plants respond to various biotic and abiotic stresses by the specific induction of a certain set of genes. This study involved a search for transcripts induced in alfalfa ( Medicago sativa L. bv Verko ) upon infection with dodder ( Cuscuta trifolii Bab. et Gibs). A 570 bp cDNA, designated PPRG1, was isolated by differential display. Southern blot analysis indicates that PPRG1 is a member of a new small gene family in alfalfa. PPRG1 encodes a putative 19·2 kDa calmodulin‐related protein with 59% amino acid homology to the touch‐inducible TCH2 gene isolated from Arabidopsis . The level of PPRG1 transcript shows a rapid transient increase to mechanical stimuli such as rain, touch and wounding, to osmotic and salt stresses and to external treatment with the plant hormone abscisic acid. Constantly elevated levels of PPRG1 mRNA can be observed during cold stress, whereas heat treatment does not induce PPRG1 expression. These results implicate roles for Ca 2+ and PPRG1 in the transduction of signals from the environment.
