“…Metabolomics is increasingly being utilized for generating deep insights into abiotic stress responses. Several studies have focused on exploring and discovering compounds that stimulate ENC plant growth by alleviating stress using various technologies (Chetia et al 2019;Kusari and Spiteller 2012;Mazlan et al 2019;Tawfike et al 2018). However, molecular signalling mechanisms employed by endophytic fungi under saline conditions are yet to be explored.…”

Salinization of soil with sodium chloride ions inhibits plant functions, causing reduction of yield of crops. Salt tolerant microorganisms have been studied to enhance crop growth under salinity. This review describes the performance of endophytic fungi applied to crops as a supplement to plant genetics or soil management to alleviate salt stress in crops. This is achieved via inducing systemic resistance, increasing the levels of beneficial metabolites, activating antioxidant systems to scavenge ROS, and modulating plant growth phytohormones. Colonization by endophytic fungi improves nutrient uptake and maintains ionic homeostasis by modulating ion accumulation, thereby restricting the transport of Na + to leaves and ensuring a low cytosolic Na + :K + ratio in plants. Participating endophytic fungi enhance transcripts of genes encoding the high Affinity Potassium Transporter 1 (HKT1) and the inwardrectifying K + channels KAT1 and KAT2, which play key roles in regulating Na + and K + homeostasis. Endophytic-induced interplay of strigolactones play regulatory roles in salt tolerance by interacting with phytohormones. Future research requires further attention on the biochemical, molecular and genetic mechanisms crucial for salt stress resistance requires further attention for future research. Furthermore, to design strategies for sustained plant health with endophytic fungi, a new wave of exploration of plant-endophyte responses to combinations of stresses is mandatory.

“…Although most studies involving Cross Kingdom QSM communication focus on human pathogens, metagenomic and transcriptomic analyses of endophytic bacterial and fungal communities reveal the presence of genes encoding for QSMs and highlight the likely importance of these molecules in endorhizosphere interactions (Sessitsch et al ., 2012; Chetia et al ., 2019). In addition, some endophytic as well as non‐endophytic bacteria and fungi are also found to be prospective sources of quorum sensing inhibitors (QSIs), SMs that impede quorum sensing regulation through a process known as quorum quenching (Mookherjee et al ., 2018; Padder et al ., 2018; Fleitas Martínez et al ., 2019; Mehmood et al ., 2019).…”

Microorganisms reside in diverse environmental communities where interactions become indispensable due to close physical associations. These interactions are driven by chemical communication among different microbial kingdoms, particularly between fungi and bacteria. Knowledge about these communication signals provides useful information about the nature of microbial interactions and allows predictions of community development in diverse environments. Here, we provide an update on the role of small signalling molecules in fungal-bacterial interactions with focus on agricultural and medicinal environments. This review highlights the range ofand response todiverse biochemicals produced by both kingdoms with view to harnessing their properties towards drug discovery applications.

The study aimed to evaluate the endophytic fungi isolated from Cocos nucifera (L.) cotyledon for their possible antimicrobial activity. A total of twelve endophytic fungal species were successfully isolated, from which five were selected and presumptively identified, including Aspergillus niger, Raffaelea sp., Aspergillus flavus, Cladosporium sp. and Pseudallescheria spp. based on their macro and microscopic characters. The agar blocks of actively growing pure culture were assessed for antibacterial activity against five human pathogenic bacterial and fungal strains: Escherichia coli (BIOTECH 1634), Bacillus subtilis (BIOTECH 1697), Staphylococcus aureus (BIOTECH 1592), Serratia marcescens (BIOTECH 1748), and Candida tropicalis (BIOTECH 2085). Among the selected five endophytic used for antimicrobial activity screening, the Raffaelea sp. (CN-EF 2) has shown a high zone of inhibition of 11 mm against Bacillus subtilis, 18 mm against Escherichia coli, 15 mm against Staphylococcus aureus, and 11 mm against Candida tropicalis. Correspondingly, Aspergillus niger (CN-EF 1) has shown a zone of inhibition of 16 mm against C. tropicalis. The endophytic fungus Raffaelea sp. was effective against all test organisms except for Serratia marcescens, while Aspergillus niger was only effective for pathogenic fungi C. albicans. Hence, further in-depth studies of the isolated endophytic fungi are needed to determine the mechanisms behind the endophytes' inhibitory effects.
