This Letter reports on a search for nu{sub m}u->nu{sub e} transitions by the MINOS experiment based on a 3.14x10{sup 20} protons-on-target exposure in the Fermilab NuMI beam. We observe 35 events in the Far Detector with a background of 27+-5(stat)+-2(syst) events predicted by the measurements in the Near Detector. If interpreted in terms of nu{sub m}u->nu{sub e} oscillations, this 1.5sigma excess of events is consistent with sin{sup 2}(2theta{sub 13}) comparable to the CHOOZ limit when |DELTAm{sup 2}|=2.43x10{sup -3} eV{sup 2} and sin{sup 2}(2theta{sub 23})=1.0 are assumed.
