New Insights into Plastid and Mitochondria Evolution in Wild Peas (Pisum L.)

Plastids and mitochondria are organelles of plant cells with small genomes, which may exhibit discordant microevolution as we earlier revealed in pea crop wild relatives. We sequenced 22 plastid mitochondrial genomes Pisum sativum subsp. elatius fulvum using Illumina platform, so that the updated sample comprised 64 accessions. Most peas from continental southern Europe a single specimen Morocco were found to share same organellar genome constitution; four others, presumably hybrid constitutions, Mediterranean islands Athos Peninsula. A closely related abyssinicum, Yemen Ethiopia, was unexpectedly an accession P. Israel, their being unrelated. Phylogenetic reconstructions based on different sets be most cultivated sativum, making its progenitor origin area enigmatic. An representing ‘fulvum-b’ branch, according nuclear marker, appeared branch other accessions trees. The results stress complicated evolution structure genetic diversity
