A simple, highly efficient Agrobacterium tumefaciens-mediated moss transformation system with broad applications.

ABSTRACT: Mosses, particularly desiccation-tolerant (DT) species, are important model organisms for studying genes involved in plant development and stress resistance. The lack of a simple and efficient stable moss transformation system has hindered progress in deciphering the genetic mechanisms underlying traits of interest in these organisms. Here, we present an Agrobacterium tumefaciens-mediated transformation system for DT mosses that uses Agrobacterium strain EHA105 harboring the binary vector pCAMBIA1301-GUS. This system achieved transformation efficiencies of 74% and 81% in Physcomitrium patens and Bryum argenteum protonemata, respectively, without the need for culture and callus formation prior to regeneration. We detected GUS enzyme activity in the regenerated tr
