Abstract ：
Reducing fertilizer inputs and improving the sustainability of sugarcane are important to the well development of China's sugar industry. In the present study, the DEA-Malmquist model was used to empirically analyze the fertilizer input and production efficiency in Guangxi, Yunnan, Guangdong and Hainan, the four main sugarcane planting provinces in China. Among these four areas, Yunnan had the maximum integrated technical efficiency level during the period from 2012 to 2021. After 2015, Hainan achieved optimum integrated technical efficiency through the growth of scale efficiency. Besides, Guangdong also achieved optimal integrated technical efficiency with increasing scale efficiency of fertilizer inputs after 2019, while Guangxi, the most important sugarcane producer in China, showed the higher redundancy in fertilizer input, accounting for 36.48-45.89% of total applications. Total Factor Productivity analysis revealed that policies have helped the major producing regions to make progress at the frontier of technological progress. However, the growth of technical efficiency change fluctuated more in Guangxi mostly due to its poor natural resource endowment and high local fertilizer costs. In summary, the integrated technical efficiency of fertilizer inputs for sugarcane cultivation in China has improved in the past, and the frontier of technical progress has shifted forward, whereas the technical efficiency of Guangxi, the largest sugarcane producer, has improved to a limited extent. We believe that the promotion of continuous industrial policies is an effective way to change the habit of using chemical fertilizers for sugarcane farmers. This study serves as a reference and a strategic basis for improving the efficiency of the sugarcane industry at the technical and scale levels.

Abstract ：
Sugar, an important commodity, is strategic for almost all countries in the world. The present study analyzed the operational data of seven sugar companies listed on the stock market in China using data envelopment analysis and panel data regression models. Results showed that Chinese sugar industry had an overall poor performance in 2012, and five of these seven companies did not achieve optimal efficiency. Considering that pure technical efficiency regarding human, physical, and financial inputs had already reached the optimum level, the main factor affecting technical efficiency was scale efficiency. Besides, after continuous adjustment and optimization of company size, all listed sugar companies in China achieved optimal efficiency in 2022, resulting in steady industry growth. An analysis on the factors affecting the stability, financial condition, operational capability, and profitability of these companies suggested that concentrated equity concentration, liabilities and owner's equity, and enterprise listing time positively influenced the improvement of comprehensive efficiency in the sugar industry. Interestingly, owing to the substantial subsidies provided by the government, the total asset turnover ratio and net profit were not significant interfering factors. Furthermore, sugar companies should continue to update equipment and technology, diversify business operations, improve their operational scale, and use endogenous development dynamics to enhance the capacity and competitiveness for sustainable development. These above results should provide valuable insights and feasible recommendations for the development of sugar industry around the world.

Abstract ：
Coordinated development of green production in sugarcane industry and the economy of the main producing areas is vital for scientifically formulating reduction policies for carbon emission and promoting high-quality industrial development. In the present study, the carbon emissions generated in sugarcane planting process were measured, and the green production efficiency along with comprehensive social development of main sugarcane-producing areas was evaluated and coupled to assess the coordination. The results indicated that carbon emission intensity from sugarcane planting in China decreased from 3.0963 tons/ha in 2012 to 2.4863 tons/ha in 2021, a decrease of 19.70%. The green development efficiency has significantly improved, rising from 0.9228 in 2012 to 1.1478 in 2021. The efficiency in Guangdong and Hainan reached its peak in 2021. Notably, the degree of coupling and coordination between green sugarcane production and comprehensive social development has progressively improved, transitioning from low- to high-level coupling and from serious imbalance to high-quality coordination. In 2021, all regions achieved a high degree of coupling and high-quality coordination. Collectively, reduced application policies in China, accompanied by the development of agricultural technology, have led to a progressive decline in carbon emissions from sugarcane planting while simultaneously improving green production efficiency. Besides, a state of mutual promotion and high-quality coordination was observed in green sugarcane production and local comprehensive social development. This study advances the theoretical framework of carbon emissions and offers empirical evidence for the ecological and economic significance of sugar industry.

Abstract ：
Intergeneric hybrids between Saccharum spp. and Erianthus arundinaceus and clones derived from these hybrids and backcrosses to Saccharum spp. were used to study the transmission of E. arundinaceus chromosomes by genomic in situ hybridization (GISH). True hybrid progenies were precisely identified using PCR with a primer pair, AGRP52/53. The results showed that AGRP52/53 was an E. arundinaceus-specific primer pair and could be used as molecular marker to assist breeding. EaHN92, a 364 bp E. arundinaceus-specific tandem repeat satellite DNA sequence, was cloned from the E. arundinaceus clone HN92-105 with AGRP52/53, and was localized on sub-telomeric regions of all E. arundinaceus chromosomes. YCE06-61, a BC3 progeny, had 7 E. arundinaceus chromosomes and its progenies had approximately 1-6 E. arundinaceus chromosomes. The number of E. arundinaceus chromosomes in true hybrids appeared as Gaussian distribution in 3 cross combinations. In addition, GISH detected intergeneric chromosome translocation in a few progenies. Hence, screening clones containing approximately 1-2 E. arundinaceus chromosomes without translocation could be used for sorting and sequencing E. arundinaceus chromosomes. This study provides a method for breeders to select true hybrid progenies between Saccharum spp. and E. arundinaceus, which will accelerate this intergeneric hybridization breeding.

Abstract ：
通过在MS培养基中添加硅,研究不同浓度的硅,对果蔗组培腋芽苗无性增殖生长及相关指标的影响。结果表明:在0~0.70 mmol/L浓度范围内,随着硅添加浓度的增加,增殖率、净生长量、绿苗周期和叶绿素含量均呈增长趋势;但当硅浓度提高到0.88 mmol/L时,除了绿苗周期小幅增加不受影响外,其它指标则表现出明显的下降趋势。在硅添加浓度为0.70 mmol/L时,增殖率、净生长量、绿苗周期、叶绿素含量和可溶性糖含量等指标较对照分别提高了38.9%、27.7%、86.7%、119.3%和67.5%,差异均达极显著水平(p<0.01)。因此,硅的最佳添加浓度为0.70 mmol/L,可极大提高果蔗组培腋芽苗的叶绿素含量,有利于提高苗的光能利用率和增加光合产物累积量,促进增殖和生长,延缓功能叶早衰,这对提高果蔗腋芽苗工厂化生产的种苗质量和生产效率,以及降低生产成本都具有积极的参考价值和应用价值。

Abstract ：
为克隆鉴定甘蔗泛素结合酶基因(Sugarcane ubiquitin-conjugating enzyme,ScUBc E2)并探索其在激素信号通路和甘蔗与黑穗病互作过程中的作用,选择黑穗病菌胁迫下甘蔗抑制消减杂交文库(Suppression subtractive hybridization,SSH)中注释为泛素结合酶的差异表达EST序列为探针,结合电子克隆技术和RT-PCR技术,以甘蔗cDNA为模板进行泛素结合酶基因克隆.对克隆获得的序列进行生物信息学分析,并利用qRT-PCR技术分析该基因在甘蔗根、蔗髓、叶、芽中的组织特异性表达以及在黑穗病菌、茉莉酸甲酯(Methyl jasmonate,Me JA)、脱落酸(Abscisic acid,ABA)和水杨酸(Salicylic acid,SA)胁迫下的表达情况.最终克隆得到一条长度为699 bp的甘蔗泛素结合酶基因(ScUBc E2;Gen Bank accession number:KJ577594.1),该基因包含长度为447 bp的完整开放读码框,编码148个氨基酸.生物信息学分析结果显示,ScUBc E2编码的蛋白分子量(Mr)为16.507×10~3;无信号肽,为碱性不稳定的亲水蛋白;包含4个α螺旋、4个β折叠和一些无规则卷曲;第15位氨基酸为泛素化位点,74-89位氨基酸为活性位点;在进化过程中与高粱泛素结合酶基因的亲缘关系最近.qRT-PCR分析结果表明,ScUBc E2基因组成型表达,但在芽中的表达量最高;其表达在甘蔗感黑穗病基因型ROC22中受到黑穗病菌胁迫的抑制,在黑穗病抗病基因型YC05-179中则先被抑制,后被诱导;ScUBc E2基因受MeJA及SA诱导表达,对ABA胁迫的响应不明显.本研究表明,甘蔗ScUBc E2基因在抗病基因型和感病基因型甘蔗中存在不同表达模式,可能参与甘蔗与黑穗病菌的互作过程,有望为抗病育种分子标记提供潜在基因资源;同时,该基因受MeJA和SA外源激素胁迫后的表达模式,可为泛素-蛋白酶体途径及激素调控的信号转导在甘蔗与黑穗病菌互作过程中的作用提供一定的理论依据.

为了了解5S rDNA和45S rDNA在斑茅染色体上的分布情况及其染色体基数,利用荧光原位杂交技术在斑茅海南92-77(2n=60)和海南92-105(2n=60)的中期染色体和间期细胞核上进行5S rDNA和45S rDNA定位研究。结果表明在海南92-77和海南92-105的中期染色体和间期细胞核上45S rDNA位点均有6个信号位点,且均位于染色体短臂的端部上;这6个45S rDNA位点大小具有明显的差异,说明斑茅的45S rDNA的拷贝数存在差异。5S rDNA位点在海南92-77和海南92-105均有6个信号位点,且均位于染色体长臂的着丝粒附近;5S rDNA位点大小相差无几,说明斑茅的5S rDNA的拷贝数差异不大。因此,可以推断染色体数目为60的斑茅染色体基数为x=10。
