Sucrose phosphate synthase and sucrose phosphate phosphatase interact in planta and promote plant growth and biomass accumulation.

Maloney VJ, Park JY, Unda F, Mansfield SD - J. Exp. Bot. (2015)

Bottom Line: Herein, the formation of an enzyme complex between SPS and SPP was examined, and the results from yeast two-hybrid experiments suggest that there is indeed an association between these proteins.The findings clearly demonstrated that SPS interacts with SPP and that this interaction impacts soluble carbohydrate pools and affects carbon partitioning to starch.Moreover, a fusion construct between the two genes promotes plant growth in both transgenic Arabidopsis and hybrid poplar.

Comparison of soluble sugar concentrations in Atsps–Arabidopsis rosette leaf tissue expressing AtSPS and AtSPP simultaneously indicates an increase in these sugars when compared with the Atsps– mutant, as well as the wild type. Data are means (± SD) of five independent plants per line. * denotes significance at P=0.05 compared with Atsps– mutant plants.
