Endophytic Candida membranifaciens from Euphorbia milii L. Alleviate Salt Stress Damages in Maize

Fungal endophytes are not widely known for their role in bioactive metabolite production and salinity stress alleviation different crop plants. Presently, we investigated the salt (NaCl, KCl, H2SO4) mitigation capabilities of fungal endophyte Candida membranifaciens (FH15) isolated from Euphorbia milii L. The pure culture filtrate (CF) C. revealed siderophore solubilization phosphate, with high levels indoleacetic acid (IAA: 35.8µg/mL), phenolics (70 µg/mL), flavonoids (50 µg/mL) by using a UV spectrophotometer. LC/MS analysis CF showed phenols that were identified as Salicylic acid, Baicalein, Aconitic Feruloylquinic Coniferyl aldehyde hexoside, Pentose, Chlorogenic Myricetin, Propoxyphene, Amino-flunitrazepam. Inoculation maize seedlings significantly (p = 0.05) enhanced fresh dry biomass, carotenoid, chlorophyll contents under 100 mM conditions. Similarly, catalase, peroxidase activity, phenols, proline relative water (RWC) plants enhanced. More interestingly, inoculation on higher endogenous IAA level compared to non-inoculated control Endophyte 20.87% 16.60% increase well root shoot length allied growth attributes, addition an adverse effects stress. Conclusively, endophytic attributes mitigated Such strain could be used further field trails enhance agricultural productivity facilitate sustainable practices.
