The plant regeneration frequencies of ealli fromplant tissue and cell culture,especially that of thecalli from rice tissue culture and rice anther cul-ture,and that of the foreign-DNA-transfor-mation-derived rice calli is very low(usually 10-15%).It is therefor very important to improve theplant regeneration frequency of rice calli.A1- 展开更多

In the recent decade,plant regeneration fromprotoplast has been obtained through embryo-genic cell suspension cultures of rice.Howev-er,not only the establishment of embryogeniccell suspension cultures of rice was difficult,but also the protoplasts became less and lessregenerable and the genetic change was gradu-ally accumulated during the prolonged culture.Since 1976(Deka.),extensive efforts have 展开更多

In this paper,we describe briefly an efficientculture procedure for micro-propagation of riceregeneration plants.The procedure consists ofthe following steps: 1.Preparation of materials Calli wereinduced from mature seeds of an indica rice lineG67 by culturing the husked and disinfectedseeds on agar medium,consisting of Nbasalelements,3% sucrose,1000mg/L proline,and 32mg/L 2,4-D.After one month's in- duction culture and 3 wk subculture,compactand nodular calli were picked out and trans- ferred into liquid medium for suspension cul-tures.The liquid medium contained the same 展开更多
