Jonny Bairstow, Gary Ballance, Jack Brooks, Alex Lees, Adam Lyth, Liam Plunkett and Adil Rashid are named in the first-class and one-day squads.
Jonathan Trott has also been selected, marking the first step towards a possible full international comeback.
The 33-year-old batsman has not featured for England since his premature departure from last winter’s Ashes tour.
The England and Wales Cricket Board have decided to reintegrate him into their plans with a place in the provisional 14-man group that will play two first-class matches against his native South Africa in January.
He will not be kept on for the five one-day matches that follow.
