TLDR
In this paper, a review encompasses the recent developments in the field of plant-microbe interaction with a focus on the positive role of beneficial microbes in improving plant growth and development.Abstract:
Soil hosts a diverse array of microorganisms like bacteria, fungi, and protozoa, among others. These microbes frequently associate with plants and interaction occurs with the environment in a unique way as a holobiome (the host genome and associated microbiome). Plant associated symbiotic microbes often augment the host with an extra layer of complex complementary functions that increase host cell plasticity and plant fitness not only under normal conditions but even during the adverse and challenging environment. Advancement in functional genomics, proteomics and metabolomics helped to understand the molecular and biochemical events during plant-microbe interaction to a larger extent. The scope of this review encompasses the recent developments in the field of plant-microbe interaction with a focus on the positive role of beneficial microbes in improving plant growth and development. In addition, the role of endophytes and their ability to modulate the biosynthesis of secondary metabolites in plants are discussed. We conclude the chapter by proposing future application with special reference to basic and applied research related to the use of beneficial microbes in sustainable crop production and its utility for varied applications.read more

Use of Endophytic and Rhizosphere Bacteria To Improve Phytoremediation of Arsenic-Contaminated Industrial Soils by Autochthonous Betula celtiberica.

TL;DR: The results corroborated the idea that recovery of pseudometallophyte-associated bacteria adapted to a large historically contaminated site and their use in bioaugmentation technologies are affordable experimental approaches and potentially very useful for implementing effective phytoremediation strategies with plants and their indigenous bacteria.

60Ma of legume nodulation. What's new? What's changing?
TL;DR: The last 10 years have seen the recognition of many new types of 'rhizobia', bacteria that can induce nodulation and fix nitrogen, and it is not yet possible to fit these into the emerging pattern of nodule evolution.

Jasmonic acid is involved in the signaling pathway for fungal endophyte-induced volatile oil accumulation of Atractylodes lancea plantlets.
Cheng-Gang Ren,Chuan-Chao Dai +1 more
TL;DR: Jasmonic acid acts as a downstream signaling molecule in NO- and H2O2-mediated volatile oil accumulation induced by endophytic fungus and has a complementary interaction with the SA signaling pathway.

Symbiotic fungi alter plant chemistry that discourages leaf-cutting ants.
TL;DR: This study shows that endophytes changed leaf chemistry and suggests that compounds with relative low volatility released after leaf wounding are a major factor influencing foraging decisions by ants when choosing between plants with low or high endophyte loads.

Sorbitol Modulates Resistance to Alternaria alternata by Regulating the Expression of an NLR Resistance Gene in Apple.

TL;DR: It is reported that decreasing sorbitol synthesis in apple leaves by antisense suppression of ALDOSE-6-PHOSPHATE REDUCTASE (A6PR) leads to downregulation of 56 NUCLEOTIDE BINDING/LEUCINE-RICH REPEAT (NLR) genes and converts the phenotypic response to Alternaria alternata from resistant to susceptible.
