Preliminary results on the pressure dependence of resistivity and magnetoresistivity in layered manganates La{sub 2{minus}2x}Sr{sub 1+2x}Mn{sub 2}O{sub 7} (x=0.3, 0.4, 0.5) are reported. Layered manganates show remarkable differences in their electron transport behavior under pressure due to the inherent structural as well as electronic and magnetic anisotropy compared to the isotropic perovskite counterparts. The pressure-induced effects and coupled magnetic field and pressure effects bring forth subtle features which enable us to distinguish the nature of electronic transitions in these layered manganates. {copyright} {ital 1998} {ital The American Physical Society}
