A fungal endophyte defensive symbiosis affects plant-nematode interactions in cotton

Biocontrol potential ofMicrobacterium maritypicumSneb159 againstHeterodera glycines

“…There has been considerable progress in the use and development of rhizosphere microorganisms as a means to manage PPN . Martinuz et al .…”

“…can improve nitrogen efficiency in maize and boost grain yields. Zhou et al (2018) also show that the leaf endophyte Phialemonium inflatum can be applied to seeds and seedlings of cotton to protect seedlings against root-knot nematode infection. Finally, Vignale et al (2018), studying the seed-borne fungus Epichloë show that plants colonized by these endophytes can affect the extramatrical development of two arbuscular mycorrhizae, Rhizophagus intraradices and Gigaspora rosea, by promoting their colonization, demonstrating that some seed-borne fungi can also affect some below ground colonizers.…”

Endophytic fungi alter sucking bug responses to cotton reproductive structures

“…We also detected occasional colonization of untreated control plants by the target endophytes, but do not know if these rare events were due to contamination prior to planting or naturally occurring colonization during subsequent plant growth. Overall, our colonization and insect behavioral findings are consistent with previous studies using these same isolates that have demonstrated endophytic colonization of cotton along with associated treatment effects on cotton aphid ( Aphis gossypium ), cotton bollworm ( Helicoverpa zea ) and root‐knot nematode ( Meloidogyne incognita ) performance and reproduction, as well as plant growth (Lopez et al ., ; Lopez & Sword, ; Zhou et al ., ,b).…”

“…Although largely ignored until recently (Porras‐Alfaro & Bayman, ; Wani et al ., ), a growing number of studies demonstrate that the presence of these facultative endophytes in the plant can be manipulated in both mono‐ and dicots through the targeted inoculation of candidate fungi. These endophyte‐colonized plants can negatively affect the performance and survival of a range of both above‐ and below‐ground herbivores (e.g., Gurulingappa et al ., ; Hernawati et al ., ; Akello & Sikora, ; Menjivar et al ., ; Gange et al ., ; Martinuz et al ., ; Thakur et al ., ; Akutse et al ., ; Batta, ; Lopez et al ., ; Lopez & Sword, ; Zhou et al ., ,b). Facultative fungal endophytes can also be involved in nutrient transfer to plants, and positively affect plant growth, thereby potentially serving as multifaceted tools for plant protection and health in agricultural systems (Behie et al ., ; Behie & Bidochka, ; Barelli et al ., ; Jaber & Enkerli, ; Lugtenberg et al ., ).…”

“…Facultative fungal endophytes have been shown to affect the feeding behavior and performance of a wide range of insect herbivores from different feeding guilds with varying effects (Hartley & Gange, ; Gange et al ., ) including phloem‐feeders such as aphids and whiteflies (Hernawati et al ., ; Akello & Sikora, ; Menjivar et al ., ; Lopez et al ., ; Zhou et al ., ,b), dipterans (Akutse et al ., ), beetles (Newcombe et al ., ; Biswas et al ., ), caterpillars (Bing & Lewis, ; Lopez & Sword, ; Thakur et al ., ; Batta, ; Zhou et al ., ,b), grasshoppers (Gurulingappa et al ., ), and hymenopteran gall wasps (Quesada‐Moraga et al ., ). Notably missing from these examples are negative effects of facultative fungal endophytes on the true bugs (Hemiptera: suborder Heteroptera).…”
