The India rupee moved up marginally by 1 paise to Rs 45.07 against dollar in the early trade today at the Interbank Foreign Exchange, supported by dollar's weakness against other major currencies.

Forex traders said that besides dollar's weakness against other currencies, positive opening at the bourses also supported the rupee.

Rupee had ended 44 paise lower at 45.08/09 against the US dollar in the previous session, following weakness in domestic equity market amid fresh dollar demand from importers and banks.

Meanwhile, the BSE 30-share index Sensex was up by 74.61 points or 0.38 per cent at 19,771.09 level in the opening trade.
