ONGOING ENDOSYMBIOTIC EVENTS. “In insects mutualistic symbionts are often associated with nutritional aspects where hosts build obligate relationships with endosymbionts. Most mutualists are in an evolutionary long-lasting host–symbiont relationship and have evolved complete vertical transmission. Among those the most specific relationships have evolved as intracellular vertical transmission, very similar to mitochondria or chloroplasts.”
