A rice double mutant was derived from the transgenic process,but it does not carry the alien gene. The mutant showed white stripe on stem, leaf and spikelet. In some growing stage,the leaf started to produce fork or curliness. The floret number increased, showing multi-lemma/palea, palea-like or lemma-like lodicules or enlarged lodicules, additional pistil and stamen and the spited floret. With observation of cell ultra structure using electron microscope,the white tissue showed concaved cell wall and abnormal plastid which could not develop normal lamellae and thylakoid. The contents of chlorophyll and net photosynthesis rate in the mutant were obviously lower than those in the wild type. The cells in green sectors grow normally with the exception of the bigger cell volume. The morphogenesis of floral organ was observed by using the scanning electron microscopy (SEM). Results showed that the stamen development was not synchronal and the sizes of stamen primordium were different in mutant, and the carpel was smaller than that of wild type.
