Abstract:
RAG, the homologue of AGAMOUS gene from Arabidopsis was isolated from rose flowers. Levels of RAG transcripts were examined in floral organs of normal flowers of cv. Ragged Robin (Rosa chinensis) that shows no characteristics of malformation, normal and malformed (phyllody-showing) flowers of cv. Motrea (Rosa hybrida) and completely malformed flowers of the stable mutant 'green rose' (Rosa chinensis viridiflora). Accumulation of RAG transcripts was evident at all stages of bud development in normal flowers of cvs. Ragged Robin and Motrea. A relatively high level of RAG mRNA, similarly to that found in the normal flowers, was also present in the reproductive organs of malformed 'Motrea' flowers at advanced stages of flower development (buds larger than 10 mm in diameter). However, more detailed analysis revealed that the accumulation of RAG transcripts in malformed organs was restricted to the ovary-sac of the transformed pistils, and did not occur in the leafy parts representing transformed style-tubes. Accumulation of RAG transcripts was not detectable at early stages of development in abnormal flowers of either cv. Motrea nor in the 'green rose'.
