“…Microorganism synthesized an iron-chelating, low molecular weight compound known as siderophore [161] that checks the pathogenic microorganism's growth by preventing the availability of iron by binding to the freely available form of iron (Fe 2+ ) in the rhizosphere [159]. PGPR produce siderophores to competitively acquire ferric ions under the iron-limiting conditions [162][163][164]. However, de Villegas et al [165] reported that increased iron concentration in the environment has a negative effect on the siderophore production.…”

Plant growth‐promoting rhizobacteria (PGPR) are diverse groups of plant‐associated microorganisms, which can reduce the severity or incidence of disease during antagonism among bacteria and soil‐borne pathogens, as well as by influencing a systemic resistance to elicit defense response in host plants. An amalgamation of various strains of PGPR has improved the efficacy by enhancing the systemic resistance opposed to various pathogens affecting the crop. Many PGPR used with seed treatment causes structural improvement of the cell wall and physiological/biochemical changes leading to the synthesis of proteins, peptides, and chemicals occupied in plant defense mechanisms. The major determinants of PGPR‐mediated induced systemic resistance (ISR) are lipopolysaccharides, lipopeptides, siderophores, pyocyanin, antibiotics 2,4‐diacetylphoroglucinol, the volatile 2,3‐butanediol, N‐alkylated benzylamine, and iron‐regulated compounds. Many PGPR inoculants have been commercialized and these inoculants consequently aid in the improvement of crop growth yield and provide effective reinforcement to the crop from disease, whereas other inoculants are used as biofertilizers for native as well as crops growing at diverse extreme habitat and exhibit multifunctional plant growth‐promoting attributes. A number of applications of PGPR formulation are needed to maintain the resistance levels in crop plants. Several microarray‐based studies have been done to identify the genes, which are associated with PGPR‐induced systemic resistance. Identification of these genes associated with ISR‐mediating disease suppression and biochemical changes in the crop plant is one of the essential steps in understanding the disease resistance mechanisms in crops. Therefore, in this review, we discuss the PGPR‐mediated innovative methods, focusing on the mode of action of compounds authorized that may be significant in the development contributing to enhance plant growth, disease resistance, and serve as an efficient bioinoculants for sustainable agriculture. The review also highlights current research progress in this field with a special emphasis on challenges, limitations, and their environmental and economic advantages.

“…Around 300,000 higher plant species cover the earth’s surface, and according to previous reports revealed that each species harbor either one or an abundance of endophytic microflora within them. Out of these plant species that present on the globe, only a few dozen, have been studied so far for their endophytic microbial community [ 8 , 66 ]. Considering this rationale and also the fact that since the flora of the Great Indian Thar Desert is full of ethnopharmacologically important plants have been studied so far for their endophytic community and their biopotential, therefore, endophytic diversity of some medicinally important plants of the Thar Desert will be discussed in this section.…”

Highlights Endophytes act as chemical synthesizers of the secondary metabolites of the host plant. Endophytic microflora has been isolated from a wide array of plants. It can serve as a good alternative source for pharmaceutically important compounds. The arid ecosystem of Thar Desert is a rich repository of ethnomedicinal plants. Role of endophytes in the synthesis of bioactive molecules used to enhance production.

Original scientific paper https://doi.org/10.2298/TSCI190703035YCotoneaster zabelii Schneid is a unique wood biological resource in China, but its natural ingredients are not used effectively. In this paper, ethanol and phenyl alcohol were used to study the leaves and branches of Cotoneaster zabelii Schneid. Gas chromatographic/mass spectrometry (GC-MS) analysis showed that Cotoneaster zabelii Schneid was rich in chemical constituents that could be used as raw materials for medicine and food. An in-depth study of Cotoneaster zabelii Schneid can provide a more accurate understanding of the value of its internal chemical composition, which can be widely applied in medicine to manufacture new drugs and promote the development of medical technology.
