In this study, the expansion of mitochondria in ferS was clearly detected utilizing fluorescence staining, when compared with the wild form. The mitochondrial expansion was identified beneath both iron-depleted and replete circumstances, suggesting a constitutive pattern (Fig. 7). In contrast, wild-type mitochondria had been expanded only under iron depletion (Fig. 7). The wild-type occurrence was constant with the phenomenon in Saccharomyces cerevisiae, in which the yeast cells can expand the mitochondrial compartments for the duration of iron starvation as a consequence of diauxic shift condition40. On the other hand, the ferS mitochondrial expansion occurred irrespective of iron availability. The expansion in mitochondrial volume results in a rise of iron pool in mitochondria, which induces the expression of high-affinity iron transporter such as Fet3 and Ftr1 under iron starvation, as reported in S. cerevisiae41. The expansion on the mitochondrial compartment, as well as mitochondrial iron pool, was consistent with all the boost in heme and Fe-S cluster-dependent proteins in TCA cycle and respiratory complexes in Ascomycetes40. In conclusion, ferS that lacks intracellular siderophore ferricrocin responds to iron-depleted and ironreplete situations using specific processes. Both iron starvation and iron excess can result in ROS generation. The ferricrocin-free mutant made oxalate (predicted by transcriptomic data) as an iron chelator. On the other hand, the induced expression of CDH could generate H2O2 and market ROS production (via the Fenton reaction), lipid peroxidation, and ferroptosis. As a result, the mutant ferS could sense the iron excess plus the oxidative pressure. In turn, the antioxidant-related genes, ergosterol biosynthesis and TCA cycle was up-regulated under both iron-depleted, and iron-replete condition. These responses are potentially analogous to the priming, in which the ferS cells are trained for adaptation to extreme stresses. Hence, these enhanced biological pathways empower the mutant ferS in the course of the host infection and lead to larger insect mortality than the wild type in the early phase of infection.Scientific Reports |(2021) 11:19624 |doi/10.1038/s41598-021-99030-11 Vol.:(0123456789)www.nature.com/scientificreports/Fungal strain and culture conditions. Beauveria bassiana BCC 2660 was a biological control strain in the Thailand Bioresource Research Center in Thailand. The wild variety and transformants had been maintained on potato dextrose agar (PDA; Difco, USA) or PDA containing 100 g mL-1 of glufosinate ammonium (Zhejiang Yongnong Chem, China), respectively, at 258 . For insect bioassay, a conidial suspension was harvested from a 7-day-old PDA culture by resuspending the conidia in distilled water and filtering them through a κ Opioid Receptor/KOR web sterile cheesecloth to eliminate mycelia.
