Abstract
Apoptosis-like programmed cell death is associated with fungal development, ageing, pathogenicity and stress responses. Here, to explore the potential of Botrytis cinerea type II inhibitor of apoptosis (IAP) BcBIR1 in elevating the biocontrol efficacy of Coniothyrium minitans, the BcBIR1 gene was heterologously expressed in C. minitans. Results indicated that the strains expressing BcBIR1 had higher rates of conidiation, mycelial growth and biomass growth than the wild-type strain. Moreover, BcBIR1 was found to inhibit apoptosis, indicating its role as an IAP in C. minitans. Under various abiotic stresses, the growth rates of BcBIR1-expressing strains were significantly higher than that of the wild-type strain. Moreover, the conidial survival rate of the BcBIR1-expressing strains treated with ultraviolet irradiation was enhanced. In antifungal activity assay, the culture filtrates of BcBIR1-expressing strains displayed a stronger inhibitory effect on B. cinerea and Sclerotinia sclerotiorum than the wild-type strain. The study also found that BcBIR1 expression increased the mycoparasitism against the sclerotia, but not the hyphae of S. sclerotiorum. Taken together, these results suggest that BcBIR1 enhances vegetative growth, conidiation, anti-apoptosis activity, abiotic stress resistance, antifungal activity and mycoparasitism in C. minitans. As an IAP, BcBIR1 may improve the control capacity of C. minitans against S. sclerotiorum.

Abstract
Magnaporthe oryzae is the causal agent of rice blast outbreaks. L-ascorbic acid (ASC) is a famous antioxidant found in nature. However, while ASC is rare or absent in fungi, a five-carbon analog, D-erythroascorbic acid (EASC), seems to appear to be a substitute for ASC. Although the antioxidant function of ASC has been widely described, the specific properties and physiological functions of EASC remain poorly understood. In this study, we identified a D-arabinono-1,4-lactone oxidase (ALO) domain-containing protein, MoAlo1, and found that MoAlo1 was localized to mitochondria. Disruption of MoALO1 (ΔMoalo1) exhibited defects in vegetative growth as well as conidiogenesis. The ΔMoalo1 mutant was found to be more sensitive to exogenous H2O2. Additionally, the pathogenicity of conidia in the ΔMoalo1 null mutant was reduced deeply in rice, and defective penetration of appressorium-like structures (ALS) formed by the hyphal tips was also observed in the ΔMoalo1 null mutant. When exogenous EASC was added to the conidial suspension, the defective pathogenicity of the ΔMoalo1 mutant was restored. Collectively, MoAlo1 is essential for growth, conidiogenesis, and pathogenicity in M. oryzae.

Endosomal sorting complexes required for transport-0 (ESCRT-0) are essential for fungal development, pathogenicity, autophagy and ER-phagy in Magnaporthe oryzae. Environ Microbiol 2021; 24:1076-1092. [PMID: 34472190 DOI: 10.1111/1462-2920.15753] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 08/28/2021] [Accepted: 08/29/2021] [Indexed: 12/23/2022]
Abstract
Magnaporthe oryzae is an important plant pathogen that causes rice blast. Hse1 and Vps27 are components of ESCRT-0 involved in the multivesicular body (MVB) sorting pathway and biogenesis. To date, the biological functions of ESCRT-0 in M. oryzae have not been determined. In this study, we identified and characterized Hse1 and Vps27 in M. oryzae. Disruption of MoHse1 and MoVps27 caused pleiotropic defects in growth, conidiation, sexual development and pathogenicity, thereby resulting in loss of virulence in rice and barley leaves. Disruption of MoHse1 and MoVps27 triggered increased lipidation of MoAtg8 and degradation of GFP-MoAtg8, indicating that ESCRT-0 is involved in the regulation of autophagy. ESCRT-0 was determined to interact with coat protein complex II (COPII), a regulator functioning in homeostasis of the endoplasmic reticulum (ER homeostasis), and disruption of MoHse1 and MoVps27 also blocked activation of the unfolded protein response (UPR) and autophagy of the endoplasmic reticulum (ER-phagy). Overall, our results indicate that ESCRT-0 plays critical roles in regulating fungal development, virulence, autophagy and ER-phagy in M. oryzae.
