By inhibiting sexual reproduction by their hosts, what advantage is gained by parasites such as endophytic fungi?

#Section 2: Evolution
  1. Asexual reproduction by plants promotes indirect transmission of the parasite
  2. Plants that reproduce asexually live longer and therefore the parasite will be able to exploit the host over a longer period of time
  3. There is no advantage—inhibition of sexual reproduction is a by-product of the infection and does not benefit the parasite
  4. It decreases the likelihood that resistant host plants will evolve
