“…Next-generation sequencing (NGS) technology has accelerated the genome sequencing and resequencing of polyploidy crops to determine molecular markers’ genetic and physical mapping in specific loci/genes. These identified markers may be used to conduct molecular marker-assisted selection (MAS) breeding or evaluate the genetic links between different accessions using genotyping technologies to improve agronomic traits. − The evolution of transcriptome sequences has improved gene interpretation by providing insight into the domestication and control of gene function networks via gene expression and sequence patterns ,− for modern breeding and genome editing.…”

Sugar cane ( Saccharum spp. hybrids) is a major crop for sugar and renewable bioenergy worldwide, grown in arid and semiarid regions. China, the world’s fourth-largest sugar producer after Brazil, India, and the European Union, all share ∼80% of the global production, and the remaining ∼20% of sugar comes from sugar beets, mostly grown in the temperate regions of the Northern Hemisphere, also used as a raw material in production of bioethanol for renewable energy. In view of carboxylation strategies, sugar cane qualifies as one of the best C 4 crop. It has dual CO 2 concentrating mechanisms located in its unique Krantz anatomy, having dimorphic chloroplasts located in mesophylls and bundle sheath cells for integrated operation of C 4 and C 3 carbon fixation cycles, regulated by enzymes to upgrade/sustain an ability for improved carbon assimilation to acquire an optimum carbon economy by producing enhanced plant biomass along with sugar yield under elevated temperature and strong irradiance with improved water-use efficiency. These superior intrinsic physiological carbon metabolisms encouraged us to reveal and recollect the facts for moving ahead with the molecular approaches to reveal the expression of proteogenomics linked with plant productivity under abiotic stress during its cultivation in specific agrizones globally.

“…For example, stress caused by abiotic factors, such as drought, high temperature and salinity, would change the plant's metabolic system, which involves oxidative stress and resistance to pathogen infection (Azevedo et al, 2011;Dossa et al, 2016). Sugarcane plants under stress, due to both biotic and abiotic factors, ultimately experience oxidative stress (Manimekalai et al, 2022), with heat severely affecting sugarcane growth, yield, quality and sugar content (Chohan, 2019). Physiologically, stressed plants are very susceptible to pathogen infection (Bashir et al, 2021).…”

Importance of the work: Environmental factors play an important role in the development of sugarcane smut disease caused by a basidiomycete fungus, Sporisorium scitamineum. Objectives: To discuss the impact of climate change on the development of sugarcane smut and the opportunity to develop a disease management system. Materials & Methods: A literature search and review was carried out relating to environmental factors (especially temperature and relative humidity) that can affect the development of sugarcane smut disease, which is favored by hot and dry conditions. This was related to an increase in temperature as one of the indicators of global climate change that could enhance the spread and development of sugarcane smut worldwide. Results: Smut disease has resulted from interactions among sugarcane as the host plant, the fungal pathogen and environmental factors favorable for disease development. A change of climate, typically indicated by an increase in temperature, could have a major influence on the incidence of the disease. In addition, the characteristics of fungal teliospores that can be dispersed easily by the wind would also improve its ability to spread and cause new infection. Therefore, the use of resistant varieties is the most appropriate control method for the disease. Furthermore, management of sugarcane trash could be considered to maintain the humidity of the soil making it less suitable for the survival of the fungus. Main finding: Resistant sugarcane varieties could be introduced supported by good cultivation practices, including the efficient use of fertilizer and incorporating sugarcane trash to the soil and decomposer amendment, to develop an integrated management approach to control sugarcane smut disease.

“…Sugarcane (Saccharum officinarum L.) is the world's primary source of sugar and bioenergy (Gravina et al, 2021), particularly for many tropical and subtropical countries where it holds significant economic importance (Manimekalai et al, 2022). Brazil is the largest global producer of this crop, followed by India and China.…”

Planting with higher density in sugarcane is one of the practices used to overcome low productivity. However, this planting material is equivalent to 25% of the total cost of production, being one of the main expenses for cultivation. In this sense, the present work aims to evaluate the productivity and economic viability of sugarcane as a function of planting density. The experiment was carried out at Usina Monte Alegre in the municipality of Mamanguape, Paraíba, Brazil, from March 2021 to January 2022 with the variety RB92579. Seven planting density were studied: T1: 7 gems m-1, T2: 10 gems m-1, T3: 12 gems m-1, T4: 11 gems m-1, T5: 15 gems m-1, T6: 17 gems m-1, T7: 24 gems m-1, in randomized blocks with four replications. Growth, productivity and economic viability were evaluated. The highest productivity of cane and sugar, 77.69 ton ha-1 and 10.390 ton ha-1, respectively, was with planting density of 17 and 24 gems-1. While the minimum productivity of cane (61.313 ton ha-1) and sugar (7.924 ton ha-1) was recorded at sowing density of 7 and 11 gems-1. However, cultivation density with 7 and 10 gems m-1 were the ones that provided the highest profitability around 50%, followed by density of 12, 15 and 17 gems m-1 with an average of 45% profit and 11 and 24 gems m-1 with the lowest proportion of profit on average 38%. The cultivation with 17 gems m-1 of cane provides in cane-plant, variety RB92579, greater productivity with a profit rate of 45%, being the most suitable.
