Abstract ：
Sugarcane is a tropical and subtropica cultivated crop that exhibits complex genetic traits. Key agronomic characteristics, such as tillering rate (T-rate) and the number of canes per hectare (NCPH), are crucial for yield optimization. This study employed a two-way pseudo-testcross strategy mapping approach with a 172 F1 population derived from 'Yuenong73-204' (low-tillering) x 'CP72-1210' (high-tillering). A genetic map spanning 1578.04 cM was constructed using 572 SNP identified via chip array genotyping. Through quantitative trait loci (QTL) mapping with LOD > 3, five QTLs linked to T-rate and four to NCPH were identified. Meanwhile, one QTL consistently present in at least two environments and one QTL present in both tillering traits. These QTLs accounted for the explanatory rate of phenotypic variation (PVE), ranging from 7.7 to 11.1% for T-rate and 5.6% to 10.7% for NCPH. Additionally, we screened one representative loci (AX-171307910) with one excellent genotype (GG), based on the QTL of qSE1/E2NCPH57 for NCPH, which excellent genotype will lead sugarcane toward better tillering traits. Finally, seven having this excellent genotype were screened. Further analysis revealed 3 relatively reliable candidate genes within the QTL of qSE1/E2NCPH57, including Soffic.01G0055400-1P, Soffic.01G0055410-1A, and Soffic.01G0055150-1A, respectively. However, RT-qPCR analysis discovered that the expression level of Soffic.01G0055400-1P and Soffic.01G0055150-A showed significant difference between Yuenong73-204 and CP72-1210, suggesting these two candidate genes were highly likely to be important genes affecting tillering. These insights offer valuable reference points for genetic enhancement strategies targeting tillers and for effective stalk development in sugarcane.

Abstract ：
Sugarcane is the most important crop for sugar production. Sugarcane streak mosaic virus (SCSMV) triggered sugarcane mosaic disease can lead to substantial reductions in both yield and sucrose content. In the process of disease prevention and control, target pathogen detection technology is indispensable. However, traditional detection methods are time-consuming and require expensive equipment, making them less efficient for timely disease control and unfavorable to disease resistance breeding. Here, we introduce a novel detection technology that combines recombinase polymerase amplification (RPA) with CRISPR-Cas12a. The method utilizes crude extracts from sugarcane leaves as the reaction template, significantly simplifying and expediting the preparation process. By combining RPA and CRISPR-Cas12a in a single reaction tube, the risk of aerosol contamination has decreased markedly. The entire process, from sample preparation to result interpretation, only takes 50 min, and the reaction equipment only a water bath pot, and results can be blue light spectrometer or UV flashlight assessed visually. Importantly, the method demonstrates high sensitivity, detecting a minimum of 50 copies of the plasmid, which surpasses the sensitivity of reverse transcription polymerase chain reaction (RT-PCR) and is comparable to quantitative RT-PCR (RT-qPCR). The method exhibits excellent specificity, showing no cross- reactivity with other common sugarcane viruses, including Sugarcane mosaic virus, Sugarcane yellow leaf virus, and Sorghum mosaic virus. The practicality of this technique was validated through the detection of leaf crude extracts from 40 field samples. The detection results were consistent with those obtained from RT-PCR and RTqPCR using leaf RNA as the template, indicating its suitability for laboratory detection and field applications.

Abstract ：
Disease resistance is one of the most important target traits for sugarcane genetic improvement. Sugarcane brown stripe (SBS) caused by Helminthosporium stenospilum is one of the most destructive foliar diseases, which not only reduces harvest cane yield but also sugar content. This study aimed to identify quantitative trait loci (QTL) and candidate genes associated with SBS resistance. Here, the phenotypic investigation in six field habitats showed a continuous normal distribution, revealing that the SBS resistance trait is a quantitative trait. Two high-density linkage maps based on the single-dose markers calling from the Axiom Sugarcane100K SNP chip were constructed for the dominant sugarcane cultivars YT93-159 (SBS-resistant) and ROC22 (SBS-susceptible) with a density of 2.53 cM and 2.54 cM per SNP marker, and mapped on 87 linkage groups (LGs) and 80 LGs covering 3069.45 cM and 1490.34 cM of genetic distance, respectively. A total of 32 QTL associated with SBS resistance were detected by QTL mapping, which explained 3.73-11.64% of the phenotypic variation, and the total phenotypic variance explained (PVE) in YT93-159 and ROC22 was 107.44% and 79.09%, respectively. Among these QTL, four repeatedly detected QTL (qSBS-Y38-1, qSBS-Y38-2, qSBS-R8, and qSBS-R46) were considered stable QTL. Meanwhile, two major QTL, qSBS-Y38 and qSBS-R46, could account for 11.47% and 11.64% of the PVE, respectively. Twenty-five disease resistance candidate genes were screened by searching these four stable QTL regions in their corresponding intervals, of which Soffic.01G0010840-3C (PR3) and Soffic.09G0017520-1P (DND2) were significantly up-regulated in YT93-159 by qRT-PCR, while Soffic.01G0040620-1P (EDR2) was significantly up-regulated in ROC22. These results will provide valuable insights for future studies on sugarcane breeding in combating this disease.

Abstract ：
Sugarcane (Saccharum spp.) is globally considered an important crop for sugar and biofuel production. During sugarcane production, the heavy reliance on chemical nitrogen fertilizer has resulted in low nitrogen use efficiency (NUE) and high loss. Up until now, there has been extensive research on the transcriptomic dynamics during sugarcane response to low nitrogen (LN) stress. However, the specific contribution of S. spontaneum to the NUE of modern sugarcane remains unclear. In the present study, the comparative transcriptome analysis of two contrasting sugarcane cultivars in response to nitrogen deficiency was performed via the combination of genomes of S. spontaneum and S. officinarum. Sub-genome analysis indicated that S. spontaneum supports the high NUE of modern sugarcane by providing genes related to nitrogen and carbohydrate metabolism, photosynthesis, and amino acid metabolism. Additionally, the key genes involved in nitrogen metabolism from the S. spontaneum were successfully identified through weighted gene co-expression network analyses (WGCNA), and a high-affinity nitrate transporter named ScNRT2.3 was subsequently cloned. Heterogeneous expression of the ScNRT2.3, a cell membrane-localized protein, could enhance the growth of Arabidopsis under low nitrate conditions. Furthermore, a conserved protein module known as NAR2.1/NRT2.3 was shown to regulate the response to LN stress in sugarcane roots through molecular interaction. This work helps to clarify the contribution of S. spontaneum to the NUE in modern sugarcane, and the function of the ScNRT2.3 in sugarcane.

Abstract ：
Sugarcane yellow leaf virus (SCYLV) can reduce sugarcane productivity. A novel detection system based on reverse transcription-multienzyme isothermal rapid amplification (RT-MIRA) combined with CRISPR-Cas12a, named RT-MIRA-CRISPR-Cas12a, was developed. This innovative approach employs crude leaf extract directly as the reaction template, streamlining the extraction process for simplicity and speed. Combining RT-MIRA and CRISPR-Cas12a in one reaction tube increases the ease of operation while reducing the risk of aerosol contamination. In addition, it exhibits sensitivity equivalent to qPCR, boasting a lower detection limit of 25 copies. Remarkably, the entire process, from sample extraction to reaction completion, requires only 52-57 minutes, just a thermostat water bath. The result can be observed and judged by the naked eye.

Abstract ：
Mosaic viral diseases affect sugarcane productivity worldwide. Mining disease resistance-associated molecular markers or genes is a key component of disease resistance breeding programs. In the present study, 285 F-1 progeny were produced from a cross between Yuetang 93-159, a moderately resistant variety, and ROC22, a highly susceptible variety. The mosaic disease symptoms of these progenies, with ROC22 as the control, were surveyed by natural infection under 11 different environmental conditions in the field and by artificial infections with a mixed sugarcane mosaic virus (SCMV) and sorghum mosaic virus (SrMV) inoculum. Analysis of consolidated survey data enabled the identification of 29 immune, 55 highly resistant, 70 moderately resistant, 62 susceptible, and 40 highly susceptible progenies. The disease response data and a high-quality SNP genetic map were used in quantitative trait locus (QTL) mapping. The results showed that the correlation coefficients (0.26 similar to 0.91) between mosaic disease resistance and test environments were significant (p< 0.001), and that mosaic disease resistance was a highly heritable quantitative trait (H-2 = 0.85). Seven mosaic resistance QTLs were located to the SNP genetic map, each QTL accounted for 3.57% similar to 17.10% of the phenotypic variation explained (PVE). Furthermore, 110 pathogen response genes and 69 transcription factors were identified in the QTLs interval. The expression levels of nine genes (Soffic.07G0015370-1P, Soffic.09G0015410-2T, Soffic.09G0016460-1T, Soffic.09G0016460-1P, Soffic.09G0017080-3C, Soffic.09G0018730-3P, Soffic.09G0018730-3C, Soffic.09G0019920-3C and Soffic.03G0019710-2C) were significantly different between resistant and susceptible progenies, indicating their key roles in sugarcane resistance to SCMV and SrMV infection. The seven QTLs and nine genes can provide a certain scientific reference to help sugarcane breeders develop varieties resistant to mosaic diseases.

Abstract ：
The processes of sugarcane tillering and ratooning, which directly affect the yield of plant cane and ratoon, are of vital importance to the population establishment and the effective stalk number per unit area. In the present study, the phenotypic data of 285 F-1 progenies from a cross of sugarcane varieties YT93-159 x ROC22 were collected in eight environments, which consisted of plant cane and ratoon cultivated in three different ecological sites. The broad sense heritability (H-2) of the tillering and the ratoon sprouting was 0.64 and 0.63, respectively, indicating that they were middle to middle-high heritable traits, and there is a significantly positive correlation between the two traits. Furthermore, a total of 26 quantitative trait loci (QTLs) related to the tillering ability and 11 QTLs associated with the ratooning ability were mapped on two high-quality genetic maps derived from a 100K SNP chip, and their phenotypic variance explained (PVE) ranged from 4.27-25.70% and 6.20-13.54%, respectively. Among them, four consistent QTLs of qPCTR-R9, qPCTR-Y28, qPCTR-Y60/qRSR-Y60 and PCTR-Y8-1/qRSR-Y8 were mapped in two environments, of which, qPCTR-Y8-1/qRSR-Y8 had the PVEs of 11.90% in the plant cane and 7.88% in the ratoon. Furthermore, a total of 25 candidate genes were identified in the interval of the above four consistent QTLs and four major QTLs of qPCTR-Y8-1, qPCTR-Y8-2, qRSR-R51 and qRSR-Y43-2, with the PVEs from 11.73-25.70%. All these genes were associated with tillering, including eight transcription factors (TFs), while 15 of them were associated with ratooning, of which there were five TFs. These QTLs and genes can provide a scientific reference for genetic improvement of tillering and ratooning traits in sugarcane.
