Such a rise is being demanded because the union argues it desires to revive pay to the degrees seen by junior docs in 2008 - with will increase since eroded by inflation.
But Health Secretary Steve Barclay says the five-day motion "collapsed" the negotiations that had been going down.
This motion follows months of wrangling between unions, the NHS and authorities over pay awards.
Non-doctor employees, together with nurses, accepted improved terms that included a one-off cost, a pay rise of 5% for many workers and 10.4% for these on the bottom wages, and a sequence of "non-pay measures to support the workforce".
Many unions accepted this provide, however some - together with the Royal College of Nursing, podiatrists, radiographers and Unite - rejected it, however misplaced their case at a plenary assembly and the settlement was imposed.
Meanwhile, NHS consultants are set to strike for 48 hours from 7am on Thursday 20 July.
According to the BMA, "junior doctors were offered an insulting and well below inflation pay rise of 2%" - which is why they need the 35% bump.
BMA leaders Dr Robert Laurenson and Dr Vivek Trivedi mentioned: "Today marks the start of the longest single walkout by doctors in the NHS's history, but this is still not a record that needs to go into the history books.
"We can name this strike off at present if the UK authorities will merely observe the instance of the federal government in Scotland and drop their nonsensical precondition of not speaking while strikes are introduced and produce a suggestion which is credible to the docs they're talking with.
"The pay offer on the table to junior doctors in Scotland and how it was reached throws into sharp relief the obstinate approach being taken by the prime minister and the health secretary, Steve Barclay.
"The well being secretary has mentioned there may be no talks whereas strikes are deliberate - Scotland has proved him mistaken. He mentioned above 5% wasn't life like - Scotland proved him mistaken. He refused to even acknowledge the idea of pay restoration - Scotland proved this isn't solely attainable however important."
Junior doctors in Scotland are to vote on a pay offer worth 17.5% over two years.
NHS Providers has called on both the unions and the government to come back to the negotiating table.
Deputy chief executive Saffron Cordery said: "Eight consecutive months of business motion throughout the NHS are taking their toll not simply on sufferers, with greater than 651,000 routine procedures and appointments compelled to be rescheduled, however on already overstretched companies - hampering efforts to chop ready lists."
Mr Barclay said: "It is disappointing that the BMA goes forward with additional strike motion. This five-day walkout by junior docs will have an effect on hundreds of sufferers, put affected person security in danger and hamper efforts to chop NHS ready lists.
"We were in discussions about pay and a range of other measures to improve the working lives of junior doctors until their representatives collapsed the negotiations by announcing further strikes.
"A pay demand of 35% or extra is unreasonable and dangers fuelling inflation, which makes everybody poorer."
