We analyze the twistor space structure of certain one-loop amplitudes ingauge theory. For some amplitudes, we find decompositions that make the twistorstructure manifest; for others, we explore the twistor space structure byfinding differential equations that the amplitudes obey.Comment: 41 pp. Reference in introduction to forthcoming new interpretation; improved analysis of -- non-supersymmetric one-loop amplitude; additional minor corrections; v.3: minor clarifications and reference adde
