Differential Regulation of Soybean Chalcone Synthase Genes in Plant Defence, Symbiosis and Upon Environmental Stimuli

Abstract

Four independent recombinant lambda clones hybridizing to parsley chalcone synthase (CHS) cDNA were isolated from a soybean (Glycine max) genomic library. Restriction fragment length polymorphism (RFLP) analysis indicated that the CHS gene family comprises six members. The CHS genes were found to be clustered with three genes on a 10 kb segment and pairs on others. DNA sequences of the 5'-, the coding-, and the 3' untranslated regions were determined for three different genes. A consensus alignment of the 5' regions revealed extensive homology between them for up to 150 bp upstream of the TATA box. Developmental regulation of CHS was observed in uninfected and in rhizobium-infected roots. Regulation at the level of transcription by different stimuli was investigated in the root, stem and cotyledons of soybean seedlings. Our results suggest a co-operative induction of CHS genes by wounding and elicitor treatment of cotyledons. The most rapid transcript accumulation, however, was observed in roots and stems. The induction of CHS genes by light was found to be UV dependent. A possible involvement of different members of the CHS gene family in response to elicitor versus UV treatment was analysed by the use of gene specific probes, and unexpectedly revealed that only CHS 1 transcription was induced by either elicitor or UV treatment of seedlings.
