Improved survival of very high light and oxidative stress is conferred by spontaneous gain-of-function mutations in Chlamydomonas

Forster, Britta; Osmond, C Barry; Pogson, Barry

Description

Investigations into high light and oxidative stress in photosynthetic organisms have focussed primarily on genetic impairment of different photoprotective functions. There are few reports of "gain-of-function" mutations that provide enhanced resistance to high light and/or oxidative stress without reduced productivity. We have isolated at least four such very high light resistant (VHLR) mutations in the green alga, Chlamydomonas reinhardtii, that permit near maximal growth rates at light...[Show more]
