Sex Reversal of Porphyra haitanensis Starting from the Unisexual Thalloid Tissue Culture
摘要
Abstract
In order to ascertain more about development of Porphyra haitanensis and investigate whether P. Haitanensls can reproduce by parthenogenesis under the unisexual culture condition. Some developmental features were observed during the development of the male and female vegetative cells and tissues, including the formation of reproductive tissues and their reproductive patterns. The results show that the unisexual cells and tissues can generate reproductive cells of both sex by sex reversal and form conchocelis. That is different from parthenogenesis in which the ovum develops into a new individual without fertilization. Two Fl young blade populations derived from the two conchocelis were investigated for their sexual expression, the results show that both F1 blade populations have male, female and hermaphrodite individuals because of sex reversal in some individuals. It is not found to be reported on the existing of sex reversal in life history of porphyra. The findings have important significance to isolation of genetic pure strains in breeding and study on sexual development mechanism.关键词
