Like Gauff, Wimbledon and US Open finalist Jabeur came into the tournament lacking form.

Before facing Bronzetti, she had played one match since retiring injured against Swiatek in Stuttgart on 22 April.

Last year Jabeur was beaten in the first round on the Roland Garros clay but avoided the same fate by making strong starts to both sets against 65th-ranked Bronzetti.

"Obviously I'm trying to get back to my level 100%, and I think that will come match by match and by playing more matches," she said.

"I'm happy that I'm healthy and I'm moving well on the court."

Jabeur, 28, faces France's world number 122 Oceane Dodin in the second round.

Elsewhere, 2021 champion Barbora Krejcikova suffered her second straight first-round exit at Roland Garros since winning her first major singles title at the event.

Krejcikova, 27, was beaten 6-2 6-4 by 34-year-old Ukrainian Lesia Tsurenko.

Meanwhile, Canada's Bianca Andreescu, 22, came back from a set down to defeat Belarusian 18th seed Victoria Azarenka 2-6 6-3 6-4.

The 2019 US Open champion, who tore two ligaments in her left ankle at the Miami Open in March, eventually clinched her fifth match point after two hours and 30 minutes on Court Simonne Mathieu.

Croatia's Petra Martic also produced a fightback to overcome American 32nd seed Shelby Rogers 3-6 6-3 6-2.

French 20-year-old Diane Parry defeated Ukrainian 25th seed Anhelina Kalinina 6-2 6-3, while Romanian 30th seed Sorana Cirstea fell 7-5 2-6 6-2 to Italy's Jasmine Paolini and Czech 31st seed Marie Bouzkova lost 6-4 7-6 (7-5) to China's Wang Xinyu.
