“…Some of these microorganisms, under elevated temperatures and high humidity, use the sugar as a source of energy for growth and produce different metabolic by-products that, on one hand, may cause processing problems in the mill and refinery and, on the other hand, can be toxic to animals and humans [33,37]. Red rot, smut, wilt and sett rot are the most important fungal diseases affecting sugarcane agriculture and causing remarkable economic losses [38,39,40]. This necessitates a detailed investigation of the probable effect of mycotoxins on the sugar industry and the other by-products such as alcohol as one of the main products derived from sugarcane.…”

This study was conducted to investigate the natural co-occurrence of multiple toxic fungal and bacterial metabolites in sugarcane grass and juice intended for human consumption in Upper Egypt. Quantification of the target analytes has been done using the “dilute and shoot” approach followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). A total number of 29 and 33 different metabolites were detected in 21 sugarcane grass and 40 juice samples, respectively, with a trend of concentrations being higher in grass than in juice. Among the regulated mycotoxins, only aflatoxin B1 (AFB1) and aflatoxin G1 (AFG1) were detected. The prevalence of AFB1 was in 48% of grass samples and in 58% of juice with a maximum concentration of 30.6 μg/kg and 2.10 μg/kg, respectively. AFG1 was detected in 10% of grass samples (7.76 μg/kg) and 18% of juice samples (34 μg/kg). Dietary exposure was assessed using a juice frequency questionnaire of adult inhabitants in Assiut City. The assessment revealed different levels of exposure to AFB1 between males and females in winter and summer seasons. The estimated seasonal exposure ranged from 0.20 to 0.40 ng/kg b.w./day in winter and from 0.38 to 0.90 ng/kg b.w./day in summer.

“…To ensure that the seed material is pathogen free, “two‐budded” setts of smut susceptible cultivar (Co 96007) were subjected to hot water treatment at 52°C for 30 min . Treated setts were inoculated by immersion in S. scitamineum 96007 (virulent isolate) teliospore suspension for 30 min.…”

Proteomic analysis of a compatible interaction between sugarcane and Sporisorium scitamineum

et al. 2016

Smut caused by Sporisorium scitamineum is one of the important diseases of sugarcane with global significance. Despite the intriguing nature of sugarcane, S. scitamineum interaction, several pertinent aspects remain unexplored. This study investigates the proteome level alterations occurring in the meristem of a S. scitamineum infected susceptible sugarcane cultivar at whip emergence stage. Differentially abundant proteins were identified by 2DE coupled with MALDI-TOF/TOF-MS. Comprehensively, 53 sugarcane proteins identified were related to defence, stress, metabolism, protein folding, energy, and cell division; in addition, a putative effector of S. scitamineum, chorismate mutase, was identified. Transcript expression vis-à-vis the activity of phenylalanine ammonia lyase was relatively higher in the infected meristem. Abundance of seven candidate proteins in 2D gel profiles was in correlation with its corresponding transcript expression levels as validated by qRT-PCR. Furthermore, this study has opened up new perspectives on the interaction between sugarcane and S. scitamineum.

Fenomena perubahan iklim terjadi karena aktivitas manusia dalam mengelola lingkungan, diantaranya adalah deforestasi, emisi gas dari kegiatan industri, dan pembakaran biomassa. Komponen iklim yang berubah, yaitu peningkatan suhu udara, konsentrasi CO2 dalam atmosfer, dan hujan berpengaruh terhadap tanaman tebu, serangga serta mikro organisme yang berasosiasi dengan tanaman tebu. Perubahan iklim lebih banyak menyebabkan pengaruh negatif terhadap tanaman tebu dan interaksi trofik antara tanaman tebu, serangga herbivora dan mikro organisme penyebab penyakit tanaman dan musuh alami herbivora maupun antagonis mikro organisme. Peningkatan suhu udara menyebabkan perubahan fisiologis pada tanaman tebu yang berakibat meningkatnya infestasi serangga herbivora dan infeksi patogen penyebab penyakit tanaman. Peningkatan komposisi CO2 dalam atmosfer menurunkan sistem ketahanan tanaman terhadap herbivora, sehingga dapat memicu terjadinya out break; dan berpengaruh positif, negatif, maupun tidak berpengaruh terhadap perkembangan penyakit tanaman. Perubahan iklim mengharuskan sistem pengelolaan serangga hama dan penyakit tanaman tebu untuk menerapkan aksi mitigasi maupun adaptasi perubahan iklim untuk memperoleh produksi tebu yang optimal dan sistem budidaya tebu yang berkelanjutan. Dalam tinjauan ini dibahas pengaruh perubahan iklim terhadap perkembangan serangga hama dan patogen penyebab penyakit pada tanaman tebu, serta strategi pengelolaannya.
