Abstract The conservation of orchids is challenging due to their strong biotic relations and tiny seeds, requiring mycorrhiza for germination. This is aggravated when tropical plants are maintained in artificial conditions of greenhouses. We aimed to select the plant growth promoting rhizobacteria (PGPR) for orchid seed germination, to study plant–microbial interactions, and to determine whether there is any specificity between two species of Dendrobium plants in choosing bacterial partners.

Plant growth promoting potential of bacterial endophytes from three terrestrial mediterranean orchid species
TLDR
The isolation of endophytic bacteria from different organs of three terrestrial Mediterranean orchid species is reported, increasing understanding of the diversity and potential PGP functions of bacterial endophytes in terrestrial orchids, and a role as beneficial partners in the orchid microbiota is suggested.
A prospectus of plant growth promoting endophytic bacterium from orchid (Vanda cristata)
TLDR
It has been concluded that PVL1 can promote plant growth through secretion of IAA during root colonization and ethyl iso-allocholate to protect plants from foreign infections to support Koch’s postulates of bacteria establishment.
Isolation and Identification of Endophytic Bacteria from Mycorrhizal Tissues of Terrestrial Orchids from Southern Chile
TLDR
The findings demonstrate the potential for plant growth promoting capabilities and some antifungal activities of endophytic bacteria inhabiting the mycorrhizal tissue of terrestrial orchids, which may contribute especially at early developmental stages of orchid seedlings.
Cyanobacterial Root Associations of Leafless Epiphytic Orchids
The leafless orchids are rare epiphytic plants with extremely reduced leaves, and their aerial roots adopted for photosynthesis. The beneficial plant–microbial interactions contribute significantly
Orchid Root Associated Bacteria: Linchpins or Accessories?
TLDR
The current, underwhelming state of RAB research including their interactions with fungi and the influence of holobionts on plant fitness is presented and a hologenomic view should be considered as a framework for addressing co-evolution of the plant host, their obligate Orchid Mycorrhizal Fungi (OMF), and orchid RAB.
Colonization strategy of the endophytic plant growth‐promoting strains of Pseudomonas fluorescens and Klebsiella oxytoca on the seeds, seedlings and roots of the epiphytic orchid, Dendrobium nobile Lindl
TLDR
This work aimed to investigate the distribution of plant growth promoting rhizobacteria (PGPR) at different stages of orchid development and to study if there is any selective specificity in choosing PGPR partners.
Current Progress on Endophytic Microbial Dynamics on Dendrobium Plants
TLDR
This chapter aims to capture the full range of studies conducted on orchid transformation through endophytic microbes with a view of providing new perspectives for future plant–microbes interaction investigations.
Indole acetic acid (IAA) producing endophytic bacteria on direct somatic embryogenesis and plant regeneration of Exacum travancoricum Bedd.
TLDR
The development of torpedo, cotyledon stage and protoderm formation without the vascular connection from explants confirmed direct somatic embryogenesis and the regeneration efficacy of IAA producing endophytic bacteria has been analysed on an endangered plant—Exacum travancoricum Bedd.
Diversity and Structure of the Endophytic Bacterial Communities Associated With Three Terrestrial Orchid Species as Revealed by 16S rRNA Gene Metabarcoding
TLDR
The results indicate that the bacterial community has adapted to colonize the orchid organs selectively and systemically, suggesting an active involvement in theOrchid holobiont.

Interaction of soil bacteria, mycorrhizal fungi and orchid seed in relation to germination of Australian orchids
TLDR
The abundance of bacteria followed a seasonal pattern that differed between orchid genera especially on the basis of the morphology of fungus infected tissue, and there was little evidence of specificity of bacterial groups to orchid taxa or part of the plant infected by the fungus.
Endophytic bacteria isolated from orchid and their potential to promote plant growth
TLDR
The results suggest that these bacterial effects could be potentially useful to promote plant growth during seedling acclimatization in orchid species other than the species of origin.
Symbiotic in vitro seed propagation of Dendrobium: fungal and bacterial partners and their influence on plant growth and development
TLDR
The strong biotic relations of Dendrobium with different associative microorganisms that form microbial communities with adult plants, and also influence symbiotic seed germination are described, and the beneficial role of plant growth-promoting bacteria is also discussed.
Effect of IAA on symbiotic germination of an Australian orchid and its production by orchid-associated bacteria
TLDR
Seven isolates of orchid-associated bacteria belonging to five species were tested for their effect on mycorrhiza-assisted germination of the terrestrial orchid Pterostylis vittata, finding symbiotic germination was enhanced by IAA, inhibited by gibberellic acid and suppressed by kinetin.
Phylloepiphytic interaction between bacteria and different plant species in a tropical agricultural system.
TLDR
The trichome type and density as well as the presence of epicuticular wax on the leaf blade surface seemed to be the most determinant anatomical features for the pattern of phyllosphere colonization.
Orchid-associated bacteria produce indole-3-acetic acid, promote seed germination, and increase their microbial yield in response to exogenous auxin
TLDR
This growth-promoting activity was observed in the absence of any plant growth stimulators or mycorrhizal fungi, usually required for orchid germination.
Auxin-producing bacteria isolated from the roots of Cattleya walkeriana, an endangered Brazilian orchid, and their role in acclimatization
TLDR
The role of auxin-producing rhizobacteria and their benefits for growth promotion of a Brazilian orchid germinated in asymbiotic conditions, during acclimatization, when plant mortality is high, limiting orchid propagation is highlighted.
Endophytic bacterial communities of field-grown potato plants and their plant-growth-promoting and antagonistic abilities.
TLDR
Seven endophytes were found to antagonize fungal as well as bacterial pathogens and showed a high production of active compounds and were therefore considered promising biological control agents.
Basic and Technological Aspects of Phytohormone Production by Microorganisms: Azospirillum sp. as a Model of Plant Growth Promoting Rhizobacteria
TLDR
This chapter concentrates information related to the biosynthesis, metabolism, regulation, physiological role, and agronomical impact of phytohormones produced by microorganisms with an emphasis on the plant growth promoting rhizobacteria belonging to the Azospirillum genus.
