Plastid disruption in a thiamine-requiring mutant of Nicotiana sylvestris blocks accumulation of specific nuclear and plastid mRNAs

Abstract

In the absence of supplemental thiamine, cotyledon leaves of the thi mutant of Nicotiana sylvestris are green, but expanding true leaves (TL) become chlorotic upon emergence and the chloroplasts fail to maintain thylakoid membrane structure. Albino TL1 is deficient in transcripts from the plastid genes psbA, psbE, and rbcL. As in carotenoid-deficient… (More)
