Ploidy Effects in Isogenic Populations of Alfalfa : III. Chloroplast Thylakoid-Bound Coupling Factor 1 in Protoplasts and Leaves.

abstract：:Isoprenoid biosynthesis in plant plastids occurs via the 1-deoxy-d-xylulose 5-phosphate (DXP) pathway. We used tobacco rattle virus (TRV) to posttranscriptionally silence the expression of the last two enzymes of this pathway, the IspG-encoded (E)-4-hydroxy-3-methylbut-2-enyl diphosphate synthase (HDS) and the IspH-en...
