Special recipe from pollens for the caste determination of honeybees

Honeybee caste differentiation is regulated by multiple factors. Here we comment an article published on August 31, 2017, Plos Genetics, which show that miRNAs from pollen may affect honeybee caste formation. Through directly silencing amTOR activity, pollen miR162a can affect ovary development and determine the fate of larvae to differentiate to worker bees. Reciprocally, miRNAs could also regulate flower development to attract more insects in...
