Functional genomics will also help scientists understand how AMF interact with
their plant symbionts at the molecular level.
For many Brucella genes, the closest matches were with a plant pathogen (Agrobacterium tumefaciens) and
a plant symbiont (Mesorhizobium loti).

Mycorrhizae, important representatives of soil fungi, live as
symbionts with
plant roots.
«This suggested that fungal
symbionts that colonize
plants which are deficient in lipid biosynthesis suffer from a lack of essential lipids,» says Andreas Keymer, a PhD student in Gutjahr's group and first author of the new study.
One noticeable beneficiary is beechdrops, a flowering
plant devoid of chlorophyll that is a
symbiont of...
Similarly,
plant cells probably acquired chloroplasts, which capture the energy of sunlight, from some early parasite or
symbiont.
Given that fungal
symbionts are quite common in some
plants, «it would be interesting to know how general this conclusion is,» he notes.
The study represents a first step towards improving understanding of
symbiont relationships and their benefit or lack of benefit, for
plant and insect species.
We will continue to study whether pathogens are exploiting mechanisms evolved to support
symbionts and, hopefully, this will allow us to establish future crop
plants that both benefit from
symbionts whilst remaining more resistant to pathogens.
Digging deeper, the symbiosis is analogous to that between
plants and their «birds and bees»
symbionts.
Herbivores may also utilize
symbionts to evade
plant defences.
Bacterial
symbionts transition between
plant pathogenicity and insect defensive mutualism...
In this system, the gall of the midge consists of a biotrophic fungal
symbiont that develops on host -
plant leaves and forms distinctly variable protective carapaces over midge larvae.
Members of the Helotiales thrive in various ecosystems and cover a broad range of niches, and helotialean fungi have been described as
plant pathogens, endophytes, mycorrhizae, fungal parasites, terrestrial saprobes, aquatic saprobes, root
symbionts, and wood rot fungi.
symbionts organisms that live together to mutual benefit [e.g., nitrogen - fixing bacteria that live with a
plant (legume)-RSB-
