England captain Alastair Cook suffered yet another failure with the bat as the top order collapsed against India on the second day of the second Test at Lord's on Friday.
Cook was out for 10, caught behind by opposing skipper Mahendra Singh Dhoni off Bhuvneshwar Kumar.
Fast-medium bowler Kumar also dismissed Australia-born opener Sam Robson and Ian Bell, England's senior batsman, on his way to figures of three for 34 in 17 overs.
At tea, England were 125 for four in reply to India's first innings 295 -- a deficit of 170 runs.
Only Zimbabwe-born Gary Ballance, with an unbeaten 51, had held firm for any length of time.
Moeen Ali was six not out.
Cook's exit meant it was now 26 innings since the left-hander had scored the last of his England record 25 Test hundreds, with his tally for the calendar years standing at meagre 107 runs in eight Test innings.
- Cook's poor run -
The 29-year-old Essex batsman's poor run of form has also coincided with an England slump that has seen the team go nine Tests without a victory -- their worst winless streak for more than 20 years.
For most of his 29-ball innings spanning 40 minutes, Cook looked assured.
But, not moving his feet, Cook nicked a good length Kunmar ball outside off stump that swung away through to India captain and wicketkeeper Mahendra Singh Dhoni.
And it was not long before 22 for one became 31 for two in front of a capacity, sun-drenched crowd.
Robson, dropped in the slips on seven, squandered his reprieve by driving loosely at a ball wide of off stump, Dhoni making no mistake with the catch
Kumar had now taken two for four in 13 balls.
At lunch, England were 51 for two, with Ballance seven not out and Bell unbeaten on 11.
Bell too has been in something of a run drought, if not as prolonged as that of Cook.
Since the third of his three Ashes centuries at Chester-le-Street last year, Bell had completed only four fifties and no hundreds in 17 Test innings prior to Thursday's knock.
And Bell had made just 16 on Friday when, trying to get out of the way of a short ball from Kumar, gloved a gentle catch to third slip.
Root, fresh his 154 not out in the drawn first Test at Trent Bridge, came in facing yet another salvage mission.
The 23-year-old's last two Tests at Lord's had yielded scores of 180 against Australia last year and 200 not out against Sri Lanka in June.
But Root was lbw for 13 to left-arm spinner Ravindra Jadeja on Friday.
Replays suggested an initial inside edge but, with the Decision Review System out of commission this series because of Indian objections, Australian umpire Bruce Oxenford's verdict stood.
It was the end of a stand of 43 between Yorkshire colleagues Ballance and Root, with England now 113 for four.
Ballance was fortunate when, on 32, he edged medium-pacer Stuart Binny between Dhoni and first slip Ajinkya Rahane for what was a keeper's catch.
Earlier, England wrapped up India's first innings when Cook held a a juggled first-slip catch to dismiss Mohammed Shami off Ben Stokes.
India had been in dire straits at 145 for seven after being sent into bat by Cook on a green, seaming pitch that was the opposite of the lifeless track at Trent Bridge.
But England let India of the hook as the tourists doubled their total to be 290 for nine at stumps, with Rahane making a superb 103 in his maiden Test innings at Lord's.
