“…Finally, the strains are divided into different subgroups according to their anastomosis frequency, culture characteristics, host species, pathogenicity, and molecular characteristics. Rice sheath blight and maize sheath blight are caused by the AG1-IA fusion group of R. solani , which can lead to severe yield loss [ 26 , 27 ].…”

Transcription factors are key molecules involved in transcriptional and post-transcriptional regulation in plants and play an important regulatory role in resisting biological stress. In this study, we identified a regulatory factor, OsZF8, mediating rice response to Rhizoctonia solani (R. solani) AG1-IA infection. The expression of OsZF8 affects R. solani rice infection. OsZF8 knockout and overexpressed rice plants were constructed, and the phenotypes of mutant and wild-type (WT) plants showed that OsZF8 negatively regulated rice resistance to rice sheath blight. However, it was speculated that OsZF8 plays a regulatory role at the protein level. The interacting protein PRB1 of OsZF8 was screened using the yeast two-hybrid and bimolecular fluorescence complementation test. The results showed that OsZF8 effectively inhibited PRB1-induced cell death in tobacco cells, and molecular docking results showed that PRB1 had a strong binding effect with OsZF8. Further, the binding ability of OsZF8-PRB1 to ergosterol was significantly reduced when compared with the PRB1 protein. These findings provide new insights into elucidating the mechanism of rice resistance to rice sheath blight.

“…A new bacterial strain, Bacillus halotolerans LDFZ001, demonstrated efficient antagonistic activity against the pathogenic strain Rhizoctonia solani [92]. The Bacillus polymyxoides SF05 strain can also be utilized to control maize sheath wilt and induce systemic resistance [93]. In Mexico, a formulation and mesoporous material of Beauveria bassiana MABb1 were employed for the biological control of maize sheath wilt [94].…”

Sheath blight (ShB) of maize, as a soil-borne disease caused by Rhizoctonia solani AG1-IA, is one of the main obstacles for maintaining the sustainable production of maize. R. solani has a wide host range and low-resistance sources, there is a lack of resistant resources against ShB, and the damage caused by ShB cannot be effectively controlled. To effectively protect crops against ShB, it is necessary to combine information about its pathogenicity and about the disease prevention and control of the pathogenic fungus and to identify areas that require more in-depth research. While progress has been made in the identification of disease-related genes in corn and pathogens, their mechanisms remain unclear. Research related to disease control involves the use of agronomic methods, chemical control, biological control, and genetic improvement. Breeding and identification of high-resistant maize varieties are key and difficult points in the control of maize sheath blight. This article reviews the research progress of the symptoms, the pathogen’s biological characteristics, the infection process, the pathogenic mechanism, and comprehensive control of maize sheath blight disease and provides future research directions of maize sheath blight in China. It aims to provide reliable technical routes and research ideas for future crop-disease-resistance research, especially to sheath blight of maize.

“…BLSB is a widespread disease that poses a significant threat to maize plants globally. This disease holds the potential to cause yield reductions ranging from 11% to 40% and, under severe conditions, can even lead to complete crop failure [2][3][4]. According to Chen [5], Songyang County in Zhejiang Province experiences a significant outbreak of BLSB every autumn.…”

Banded leaf and sheath blight (BLSB) in maize is a soil-borne fungal disease caused by Rhizoctonia solani Kühn, resulting in significant yield losses. Investigating the genes responsible for regulating resistance to BLSB is crucial for yield enhancement. In this study, a multiparent maize population was developed, comprising two recombinant inbred line (RIL) populations totaling 442 F8RILs. The populations were generated by crossing two tropical inbred lines, CML444 and NK40-1, known for their BLSB resistance, as female parents, with the high-yielding but BLSB-susceptible inbred line Ye107 serving as the common male parent. Subsequently, we utilized 562,212 high-quality single nucleotide polymorphisms (SNPs) generated through genotyping-by-sequencing (GBS) for a comprehensive genome-wide association study (GWAS) aimed at identifying genes responsible for BLSB resistance. The objectives of this study were to (1) identify SNPs associated with BLSB resistance through genome-wide association analyses, (2) explore candidate genes regulating BLSB resistance in maize, and (3) investigate pathways involved in BLSB resistance and discover key candidate genes through Gene Ontology (GO) analysis. The GWAS analysis revealed nineteen SNPs significantly associated with BLSB that were consistently identified across four environments in the GWAS, with phenotypic variation explained (PVE) ranging from 2.48% to 11.71%. Screening a 40 kb region upstream and downstream of the significant SNPs revealed several potential candidate genes. By integrating information from maize GDB and the NCBI, we identified five novel candidate genes, namely, Zm00001d009723, Zm00001d009975, Zm00001d009566, Zm00001d009567, located on chromosome 8, and Zm00001d026376, on chromosome 10, related to BLSB resistance. These candidate genes exhibit association with various aspects, including maize cell membrane proteins and cell immune proteins, as well as connections to cell metabolism, transport, transcriptional regulation, and structural proteins. These proteins and biochemical processes play crucial roles in maize defense against BLSB. When Rhizoctonia solani invades maize plants, it induces the expression of genes encoding specific proteins and regulates corresponding metabolic pathways to thwart the invasion of this fungus. The present study significantly contributes to our understanding of the genetic basis of BLSB resistance in maize, offering valuable insights into novel candidate genes that could be instrumental in future breeding efforts to develop maize varieties with enhanced BLSB resistance.
