Modification of plant development and plant differentiation by use of tissue specific Deac gene expression system

摘要

Instant invention relates to a method for the modification or delay of meristem differentiation and/or development by tissue- and/or developmental-specific expression of a deacetylase gene (deac) encoding a protein exhibiting N-acetyl-PPT (e.g., N-acetyl-phosphinothricine) specific deacetylase activity in combination with the application of a composition containing one or more non-toxic compound(s) (e.g., N-acetyl-PPT), allowing - after deacetylation within the plant cell - inducible and selective modification of meristem cells within a living plant in order to modify differentiation and/or development of the plant.
