Studies on the behavior of meiotic protoplasts II. Induction of a high fusion frequency in protoplasts from liliaceous plants
Department of Biology, Faculty of Science, Nagoya University Nagoya 464, Japan
A method for the induction of high fusion frequencies in meiotic protoplasts of a lily and Trillium is described. Fusion was induced during the rapid isolation of protoplasts by quickly bringing about physical contact between protoplasts. Fused protoplasts were obtained in 50 to 90% yields from prophase cells and in 30 to 60% yields from cells in later phases. Large protoplasts with more than 10 nuclei were frequently produced. During culture, meiotic development was not synchronous in these protoplasts; each multinudeate maintaining a high degree of synchrony.
