摘要: The shooty rice (Oryza sativa L.) mutant produced on average 192 buds from a single shoot within one month. Numerous shoots carrying the same phenotype were easily regenerated from a small piece of any growing bud after dedifferentiation and callus induction. These traits were inherited by subcultures of all the generations without loss of the vigorous multiplying capability. The shooty phenotype was correlated with an elevated endogenous isopentenyl adenine (2iP) content. Addition of 2iP to the growth media promoted differentiation of wild-type rice callus to large extent, but had little effect on plant regeneration. This mutant may hold a key toward understanding of monocotyledonous (cereal) plant regeneration. [References: 21]
