Twisting Pseudo-response regulators improve biomass and tolerance in Arabdopsis thaliana
Research study led by Norihito Nakamichi and Hitoshi Sakakibara from RIKEN Center for Sustainable Resource Science-Japan discoverded that “A solitary hereditary change is all it takes to make plants deliver more biomass and turn out to be stronger to push unfavourable growth enviromnets”.
The team had investigated deeply on pseudo- response regulator (PRR) gene family of four and concluded that PRR genes regulate plants cercadian clock and found that a mutation in cluster of three genes out of four PRR genes mutated had tolerance and produce increased biomass. However the mutations in single gene of PRR had very little effect.
The group successfully engineered a mutated form of PRR5 gene and activated its targets continuously. The plants with mutated PRR5 showed qualities of improved biomass and tolerance to stress. The PRR5 mutants survived extreme cold conditions and sustained very well in drought conditions for up to 16 days.
This development, which is vital in light of worldwide environmental change, will encourage research into these procedures and endeavors to enhance them.
