“…OsWRKY53, a newly identified rice BR signal transducer, has been shown to positively regulate BR signaling (Tian et al, 2017). Gao et al (2021) showed that OsWRKY53 directly activates the expression of OsSWEET2a, a negative regulator of rice resistance to ShB, to confer susceptibility to ShB (Gao et al, 2021). These results provide insight into BR-mediated susceptibility to ShB in rice.…”

“…It was found that the WRKY36-SWEET11 signaling pathway negatively regulates rice ShB and increases the resistance of transformed rice without affecting yield through the interaction of the mesophyll cell-specific mutant SWEET11 and the wild-type (WT) (Gao et al, 2018). Brassinosteroid (BR)-mediated WRKY53 and MPK6 signaling may balance SWEET2a expression and thus negatively regulate rice resistance to ShB (Gao et al, 2021). In addition, AMT1;1-mediated NH + 4 transport can accelerate nitrogen metabolism in rice and regulate the expression of subsequent NH + 4 -dependent ethylene-related genes, thereby promoting rice resistance to ShB and suggesting that appropriate nitrogen uptake and assimilation are necessary for rice defense activation (Wu 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.

“…Among these TFs, we checked the expression of some TFs and their target genes, such as DOF11 and target SWEET14 [ 33 ], and WRKY53 and target SWEET2a [ 34 ]. The expression trends were the same as those of the transcriptomes ( Figure S2A,B ).…”

“…( Table S3 ). Moreover, some TFs and their targets, DOF11, SWEET14, WRKY53, and SWEET2a ( Figure S2A,B ), have been reported to be involved in sheath blight resistance in rice [ 33 , 34 ]. Moreover, chitinase activity (GO:0004568), one of the most significant enriched processes in MF in Tongxi926 leaves ( Figure 3 B), has been demonstrated to significantly correlate with sheath blight resistance in McCHIT1-transgenic rice line plants [ 80 ].…”

Rice (Oryza sativa) is one of the most important crops grown worldwide, and saline–alkali stress seriously affects the yield and quality of rice. It is imperative to elucidate the molecular mechanisms underlying rice response to saline–alkali stress. In this study, we conducted an integrated analysis of the transcriptome and metabolome to elucidate the effects of long-term saline–alkali stress on rice. High saline–alkali stress (pH > 9.5) induced significant changes in gene expression and metabolites, including 9347 differentially expressed genes (DEGs) and 693 differentially accumulated metabolites (DAMs). Among the DAMs, lipids and amino acids accumulation were greatly enhanced. The pathways of the ABC transporter, amino acid biosynthesis and metabolism, glyoxylate and dicarboxylate metabolism, glutathione metabolism, TCA cycle, and linoleic acid metabolism, etc., were significantly enriched with DEGs and DAMs. These results suggest that the metabolites and pathways play important roles in rice’s response to high saline–alkali stress. Our study deepens the understanding of mechanisms response to saline–alkali stress and provides references for molecular design breeding of saline–alkali resistant rice.

“…72 OsSWEET2a negatively regulates the resistance of rice to sheath blight because the ossweet2a mutant is less susceptible to ShB. 73 Furthermore, in horticultural and agricultural crops, B. cinerea is a widespread and highly disseminated fungal pathogen. Discovering and exploiting the host susceptibility genes can effectively enhance plant resistance to this devastating disease.…”

The occurrence of plant diseases severely affects the quality and quantity of plant production. Plants adapt to the constant invasion of pathogens and gradually form a series of defense mechanisms, such as pathogen-associated molecular pattern-triggered immunity and microbial effector-triggered immunity. Moreover, many pathogens have evolved to inhibit the immune defense system and acquire plant nutrients as a result of their coevolution with plants. The sugars will eventually be exported transporters (SWEETs) are a novel family of sugar transporters that function as uniporters. They provide a channel for pathogens, including bacteria, fungi, and viruses, to hijack sugar from the host. In this review, we summarize the functions of SWEETs in nectar secretion, grain loading, senescence, and long-distance transport. We also focus on the interaction between the SWEET genes and pathogens. In addition, we provide insight into the potential application of SWEET genes to enhance disease resistance through the use of genome editing tools. The summary and perspective of this review will deepen our understanding of the role of SWEETs during the process of pathogen infection and provide insights into resistance breeding.
