This entry represents a group of plant proteins, including protein PLASTID MOVEMENT IMPAIRED 1 (PMI1) and PMIR1/2 from Arabidopsis. PMI1 and PMIR1 are required for efficient chloroplast photorelocation movement. However, PMIR2 seems not necessary for chloroplast and nuclear photorelocation movements [ 1 ]. PMI1 has been found to mediate ABA sensitivity during germination [ 2 ].
