The First Plastid Genome of the Holoparasitic Genus Prosopanche (Hydnoraceae).

ABSTRACT: Plastomes of parasitic and mycoheterotrophic plants show different degrees of reduction depending on the plants' level of heterotrophy and host dependence in comparison to photoautotrophic sister species, and the amount of time since heterotrophic dependence was established. In all but the most recent heterotrophic lineages, this reduction involves substantial decrease in genome size and gene content and sometimes alterations of genome structure. Here, we present the first plastid genome of the holoparasitic genus Prosopanche, which shows clear signs of functionality. The plastome of Prosopanche americana has a length of 28,191 bp and contains only 24 unique genes, i.e., 14 ribosomal protein genes, four ribosomal RNA genes, five genes coding for tRNAs and three genes with oth
