WebFeb 13, 2014 · The evolution of leprosy bacilli occurred in two stages: the initial period up to 20 Myr ago, during which the last common ancestor underwent a massive reductive evolution to become a niche-adapted parasite with the smallest and least functional mycobacterial genome, and a second period ∼10 Myr to now, which began with the … WebApr 28, 2024 · Parasitism in plants coincides with novel genes and newly rewired genetic pathways, whereby evolutionary novelty derives from changes in the parasitic plants' nuclear genomes. Genome evolution in parasites is an interplay of functional gain and plant tissue- or function-specific gene losses as parasitic specialization unfolds.
