  Recent transport experiments in the cuprate superconductors linked the
opening of the pseudogap to a change in electronic dispersion [S. Badoux et
al., Nature 531, 210 (2015)]. Transport measurements showed that the carrier
density sharply changes from $x$ to $1+x$ at the pseudogap critical doping, in
accordance with the change from Fermi arcs at low doping to a large hole Fermi
surface at high doping. The SU(2) theory of cuprates shows that
antiferromagnetic short range interactions cause the arising of both charge and
superconducting orders, which are related by an SU(2) symmetry. The
fluctuations associated with this symmetry form a pseudogap phase. Here we
derive the renormalised electronic propagator under the SU(2) dome, and
calculate the spectral functions and transport quantities of the renormalised
bands. We show that their evolution with doping matches both spectral and
transport measurements.
