“…Additional evidence is that OsSWEET2a negatively regulates rice resistance to ShB (Gao et al, 2021). Furthermore, the R. solani AG1-IA effector AOS2 that is secreted and targeted in the nucleus, interacts with WRKY53 and grassy tiller 1 (GT1) to activate SWEET2a and SWEET3a resulting in sugar efflux for nutrition (Yang et al, 2022). In addition, a recent study identified new QTLs for ShB resistance which included OsSWEET13 and 14 (Li et al, 2022).…”

Rice sheath blight (ShB) disease poses a major threat to rice yield throughout the world. However, the defense mechanisms against ShB in rice remain largely unknown. ShB resistance is a typical quantitative trait controlled by multiple genes. With the rapid development of molecular methods, many quantitative trait loci (QTLs) related to agronomic traits, biotic and abiotic stresses, and yield have been identified by genome-wide association studies. The interactions between plants and pathogens are controlled by various plant hormone signaling pathways, and the pathways synergistically or antagonistically interact with each other, regulating plant growth and development as well as the defense response. This review summarizes the regulatory effects of hormones including auxin, ethylene, salicylic acid, jasmonic acid, brassinosteroids, gibberellin, abscisic acid, strigolactone, and cytokinin on ShB and the crosstalk between the various hormones. Furthermore, the effects of sugar and nitrogen on rice ShB resistance, as well as information on genes related to ShB resistance in rice and their effects on ShB are also discussed. In summary, this review is a comprehensive description of the QTLs, hormones, nutrition, and other defense-related genes related to ShB in rice. The prospects of targeting the resistance mechanism as a strategy for controlling ShB in rice are also discussed.

“…Recent research has demonstrated that the infection by the rice blast fungus may activate the BR signal via WRKY53 and induce SWEET2a expression via negative regulation of rice ShB resistance ( Gao et al., 2021 ). Further research identified that the effector AOS2 secreted by R. solani interacts with WRKY53 and GT1 to form a transcription factor complex, activating the SWEET genes (including SWEET2a and 3a ) and increasing the virulence of fungi through nutritional competition ( Yang et al., 2022 ). During the symbiosis of Medicago truncatula and arbuscular mycorrhizal (AM) fungi, MtSWEET1b is also induced to promote a glucose efflux carrier ( An et al., 2019 ).…”

As the primary energy source for a plant host and microbe to sustain life, sugar is generally exported by Sugars Will Eventually be Exported Transporters (SWEETs) to the host extracellular spaces or the apoplast. There, the host and microbes compete for hexose, sucrose, and other important nutrients. The host and microbial monosaccharide transporters (MSTs) and sucrose transporters (SUTs) play a key role in the “evolutionary arms race”. The result of this competition hinges on the proportion of sugar distribution between the host and microbes. In some plants (such as Arabidopsis, corn, and rice) and their interacting pathogens, the key transporters responsible for sugar competition have been identified. However, the regulatory mechanisms of sugar transporters, especially in the microbes require further investigation. Here, the key transporters that are responsible for the sugar competition in the host and pathogen have been identified and the regulatory mechanisms of the sugar transport have been briefly analyzed. These data are of great significance to the increase of the sugar distribution in plants for improvement in the yield.

Rice sheath blight (RSB), caused by Rhizoctonia solani, is a significant disease of rice. The negative effects of chemical fungicides have created an urgent need for low‐toxicity botanical fungicides. Our previous research revealed that the ethanol crude extract of Moutan Cortex (MC) exhibited superior antifungal activity against R. solani at 1000 μg/mL, resulting in 100% inhibition rate. And the antifungal properties were mainly found in the petroleum ether extract. However, the active ingredients of the extract are still unclear. In this study, gas chromatography‐mass spectrometry (GC‐MS) was utilised for the analysis of its chemical components. The mycelium growth rate method was utilized to detect the antifungal activity. The findings indicated that paeonol constituted the primary active component, with a content of more than 96%. Meanwhile, paeonol was the most important antifungal active ingredient, the antifungal activity of paeonol (EC50 = 44.83 μg/mL) was much higher than that of β‐sitosterol and ethyl propionate against R. solani. Observation under an optical microscope revealed that paeonol resulted in abnormal mycelial morphology. This study provided theoretical support for identifying monomer antifungal compounds and developing biological fungicides for R. solani.
