“…In this connection, a transcriptome study involving wheat plants inoculated with Ochrobactrum pseudogrignonense was shown to improve the level of stress tolerance by the upregulation of genes encoding for the enzymatic antioxidants, viz. peroxidase, chitinase, phenylalanine ammonia lyase, and glucanase (Chakraborty et al, 2019b). Similarly, the transcriptome analysis of the rice plants inoculated with P. indica revealed the upregulation of several genes which encoded for the cell wall biosynthesis enzymes (glycosyl hydrolase, elastin precursor, pectin esterase), and phytohormone signaling and biosynthesis (Cytokinin dehydrogenase, 9‐cis‐epoxycarotenoid dioxygenase 1, Ent‐kaurene synthase) helped the plants to withstand the adverse effects of salinity in a better way (Nivedita et al, 2020).…”

Soil salinity severely affects plant growth and development and imparts inevitable losses to crop productivity. Increasing the concentration of salts in the vicinity of plant roots has severe consequences at the morphological, biochemical, and molecular levels. These include loss of chlorophyll, decrease in photosynthetic rate, reduction in cell division, ROS generation, inactivation of antioxidative enzymes, alterations in phytohormone biosynthesis and signaling, and so forth. The association of microorganisms, viz. plant growth‐promoting rhizobacteria, endophytes, and mycorrhiza, with plant roots constituting the root microbiome can confer a greater degree of salinity tolerance in addition to their inherent ability to promote growth and induce defense mechanisms. The mechanisms involved in induced stress tolerance bestowed by these microorganisms involve the modulation of phytohormone biosynthesis and signaling pathways (including indole acetic acid, gibberellic acid, brassinosteroids, abscisic acid, and jasmonic acid), accumulation of osmoprotectants (proline, glycine betaine, and sugar alcohols), and regulation of ion transporters (SOS1, NHX, HKT1). Apart from this, salt‐tolerant microorganisms are known to induce the expression of salt‐responsive genes via the action of several transcription factors, as well as by posttranscriptional and posttranslational modifications. Moreover, the potential of these salt‐tolerant microflora can be employed for sustainably improving crop performance in saline environments. Therefore, this review will briefly focus on the key responses of plants under salinity stress and elucidate the mechanisms employed by the salt‐tolerant microorganisms in improving plant tolerance under saline environments.

“…Of these, only Alteromonadales bacteria are core components of diatom phycosphere communities [20], but Rhizobiales bacteria have been found in association with the diatom Asterionellopsis glacialis [54]. Burkholderiales and Rhizobiales are commonly found in plant rhizospheres [55, 56]. Differences in Phaeocystis phycosphere community composition compared to other phytoplankton reflects the uniqueness of the Phaeocystis colony microenvironment.…”

“…From the order Rhizobiales, one core ASV shared 100% identity with Ochrobactrum pseudogrigonensis sequences. O. pseudogrigonensis is a rhizosphere bacteria that promotes plant growth through induced stress tolerance, e.g ., by producing antioxidants [56]. The other core Rhizobiales ASV shared 100% identity with Rhizobium radiobacter .…”

Phaeocystis is a cosmopolitan, bloom-forming phytoplankton genus that contributes significantly to global carbon and sulfur cycles. During blooms, Phaeocystis species produce large carbon-rich colonies, thus creating a unique interface for bacterial interactions. While bacteria are known to interact with phytoplankton - e.g., they promote growth by producing phytohormones and vitamins - such interactions have not been shown for Phaeocystis. Therefore, we investigated the composition and function of P. globosa microbiomes. Specifically, we tested whether microbiome compositions are consistent across individual colonies from four P. globosa strains, whether similar microbiomes are re-recruited after antibiotic treatment, and how microbiomes affect P. globosa growth under limiting conditions. Results illuminated a core colonial P. globosa microbiome - including bacteria from the orders Alteromonadales, Burkholderiales, and Rhizobiales - that was re-recruited after microbiome disruption. Consistent microbiome composition and recruitment is indicative that P. globosa microbiomes are stable-state systems undergoing deterministic community assembly and suggests there are specific, beneficial interactions between Phaeocystis and bacteria. Growth experiments with axenic and nonaxenic cultures demonstrated that microbiomes allowed continued growth when B-vitamins were withheld, but that microbiomes accelerated culture collapse when nitrogen was withheld. In sum, this study reveals interactions between Phaeocystis colonies and microbiome bacteria that could influence large-scale phytoplankton bloom dynamics and biogeochemical cycles.

Soil salinity, a pervasive issue exacerbated by factors like irrigation and climate change, poses a significant threat to global food security. The accumulation of salts not only hampers crop growth and yield but also jeopardizes the livelihoods of millions who depend on agriculture for sustenance. Elevated salt levels in saline soils induce osmotic, ionic, oxidative, and water stress in plants. Implementing biological solutions offers the most dependable and sustainable method to safeguard food security while reducing reliance on agrochemicals which hampers various physiological and metabolic processes in plants. To ensure optimal plant growth under such changing conditions, Implementing biological solutions (Rhizobacteria) offers the most dependable and sustainable method to safeguard food security while reducing reliance on agrochemicals must be integrated into agricultural practices. This chapter concisely explores the mechanisms and utilization of beneficial microorganisms in both plants and soil to mitigate salt stress. It also addresses the current limitations and suggests potential areas for improvement in future research.
