“…Sugarcane holds significant importance in the global economy, particularly in terms of biofuel and sugar production (FAOSTAT 2023). Due to its remarkable capacity for sugar storage, sugarcane is the primary global source of sugar (Mirajkar et al 2019). With the continual rise in sugar demand, there is a pressing need for the development of more productive varieties.…”

Sugarcane (Saccharumspp.) holds significant economic importance in sugar and biofuel production. Despite extensive research, understanding highly quantitative traits, such as sucrose content, remains challenging due to the complex genomic landscape of the crop. In this study, we conducted a multiomic investigation to elucidate the genetic architecture and molecular mechanisms governing sucrose accumulation in sugarcane. Using a biparental cross (IACSP95-3018 × IACSP93-3046) and a genetically diverse collection of sugarcane genotypes, we evaluated the soluble solids (Brix) and sucrose content (POL) across various years and environments. Both populations were genotyped using a genotyping-by-sequencing (GBS) approach, with single nucleotide polymorphisms (SNPs) identified via bioinformatics pipelines. Genotype‒phenotype associations were established using a combination of traditional linear mixed-effect models and machine learning algorithms. Furthermore, we conducted an RNA sequencing (RNA-Seq) experiment on genotypes exhibiting distinct Brix and POL profiles across different developmental stages. Differentially expressed genes (DEGs) potentially associated with variations in sucrose accumulation were identified. All findings were integrated through a comprehensive gene coexpression network analysis. Strong correlations among the evaluated characteristics were observed, with estimates of modest to high heritabilities. By leveraging a broad set of SNPs identified for both populations, we identified several SNPs potentially linked to phenotypic variance. Our examination of genes close to these markers facilitated the association of such SNPs with DEGs in genotypes with contrasting sucrose levels. Through the integration of these results with a gene coexpression network, we delineated a set of genes potentially involved in the regulatory mechanisms of sucrose accumulation in sugarcane, collectively contributing to the definition of this critical phenotype. Our findings constitute a significant resource for biotechnology and plant breeding initiatives. Furthermore, our genotype‒phenotype association models hold promise for application in genomic selection, offering valuable insights into the molecular underpinnings governing sucrose accumulation in sugarcane.

“…Saccharum o cinarum l., commonly known as sugarcane, is a perennial grass that has proven adaptable to a wide range of climatic environments (Dillewijn, 1952;Zhao & Li, 2015;Mirajkar et al, 2019;Ali et al, 2021;Chen & Chung-Chi Chou, 1993). The major sugarcane-producing countries lie in the Asia Paci c, South America, and Caribbean regions.…”

The potential impacts of climate change and sugar cane production is well documented in the literature but majority of the studies have focused on models that look at national level impacts. This paper presents a global impact model on sugar cane production due to variations in temperature and rainfall with the intention to observe the collective challenges that sugar cane production is facing with across the world. The study conducted a trend analysis with time series data for sugar cane production, productivity per hectare of sugar cane lands, annual temperature and annual rainfall recorded for the top sugar cane exporters across the world. The study also developed a panel regression model to empirically establish the relationship between production levels and temperature and rainfall. The findings of the study showed that production levels are increasing in some countries while declining in others. Cyclical patterns of production was also observed that seem to vary with cyclical patterns of rainfall. The regression model showed a positive relationship between production and rainfall and a negative relationship between production and temperature. The main conclusion drawn is that as global temperatures continue to increase, then there will be a global decline in the sugarcane industry. This global model for sugar cane and climate change is geared towards showing the collective impacts of climate change experienced by different countries and to encourage from an empirical standpoint, more collective policy actions to protect the industry as a global market.

“…A. auriculiformis trees can also be used as a source of biomass energy due to their rapid growth, ability to thrive in a variety of marginal environments, and ease of cultivation (Hendrarti et al 2014). This tree has been harvested as an industrial raw material for sawn timber until now (Nirsatmanto and Sunarti 2019). Empirically, A. auriculiformis was used for treating rheumatic (root part), skin (seed part), malarial (seed part), and depressant (not specified part) (Rangra et al 2019a;Subhan et al 2018).…”

Acacia auriculiformis showed good potential to be developed as a raw material for bioactive compounds. The heartwood of A. auriculiformis is still rarely explored. The purpose of this study was to identify the bioactive components of the heartwood. Six compounds were identified from the heartwood through nuclear magnetic resonance and mass spectroscopy, namely the C-3,4',7,8 hydroxyl substituted flavonoids and chalcone. Two methylated teracacidins and chalcone-like teracacidin were identified for the first time in the A. auriculiformis heartwood, along with three known compounds. These compounds showed good radical scavenging and reduction activity, compared to crude extract and ascorbic acid, using three different antioxidant assays. The molecular structure-dependent activity was observed to affect the trend of the different antioxidant activities. This finding shows good potential for further development of plant parts of A. auriculiformis from Indonesia as new raw materials for medicines. Keywords: Acacia auriculiformis, antioxidant, chalcone, flavonoid, heartwood
