Sugarcane (Saccharum spp.) is a tropical and sub-tropical, vegetative-propagated crop that contributes to approximately 80% of the sugar 40% world's biofuel production. Modern sugarcane cultivars are highly polyploid aneuploid hybrids with extremely large genomes (>10 Gigabases), have originated from artificial crosses between two species, Saccharum officinarum S. spontaneum. The genetic complexity low fertility under natural growing conditions make traditional breeding improvement laborious, costly time-consuming. This, together its vegetative propagation, which allows for stable transfer multiplication transgenes, good candidate through engineering. Genetic transformation has potential improve economically important properties in as well diversify beyond applications, such sucrose Traits herbicide, disease insect resistance, improved tolerance cold, salt drought accumulation biomass been some areas interest far application transgenic concerned. Although there much developing only three officially approved varieties commercialization, all them expressing insect-resistance recently released Brazil. Since early 1990's, different systems successfully developed sugarcane, including electroporation, Agrobacterium tumefaciens biobalistics. However, very laborious process, relies heavily on intensive sophisticated tissue culture plant generation procedures must be optimized each new genotype transformed. Therefore, it remains great technical challenge develop an efficient protocol any variety not previously Additionally, once event obtained, molecular studies required commercial release by regulatory authorities, include transgene insertion site, number transgenes gene expression levels, hindered genomic lack complete sequenced reference genome this crop. objective review summarize current techniques state art provide information existing future

Environmental stresses are the main constraints on agricultural productivity and food security worldwide. This issue is worsened by abrupt severe changes in global climate. The formation of sugarcane yield accumulation sucrose significantly influenced biotic abiotic stresses. Understanding biochemical, physiological, environmental phenomena associated with these essential to increase crop production. review explores effect factors content highlights negative effects insufficient water supply, temperature fluctuations, insect pests, diseases. article also explains mechanism reactive oxygen species (ROS), role different metabolites under stresses, function stress-related resistance genes sugarcane. further discusses improvement approaches, a focus endophytic consortium endophyte application plants. Endophytes vital plant defense; they produce bioactive molecules that act as biocontrol agents enhance immune systems modify responses through interaction provides an overview internal mechanisms growth offers new ideas for improving fitness productivity.

Sugarcane is the most important sugar and energy crop in world. During sugarcane breeding, technology requirement methods are means. As we know, seed cornerstone of development industry. Over past century, with advancement expansion methods, breeding has continued to improve, production realized a leaping growth, providing large amount essential clean for long-term mankind development, especially face future threats world population explosion, reduction available arable land, various biotic abiotic stresses. Moreover, due narrow genetic foundation, serious varietal degradation, lack breakthrough varieties, as well long cycle low probability gene polymerization, it particularly realize leapfrog by seizing opportunity emerging Breeding 4.0, making full use modern biotechnology including but not limited whole genome selection, transgene, editing, synthetic biology, combined information such remote sensing deep learning. In view this, focus on from perspective reviewing main history, pointing out current status challenges, reasonable outlook prospects smart breeding.

Production of sugarcane and more recently energy cane strengthen renewable bioenergy production capacity. However, droughts resulting from climate change have limited the these crops. One strategies to attenuate water deficit damage in crops is use silicate, which contributes plant physiology. This strategy likely increase efficiency, thus promoting crop sustainability. Notwithstanding, studies on this issue are still incipient. study assesses whether Si applied via fertigation foliar spraying seedling phase as a complement after transplanting soil efficient attenuating cane. The further elucidates physiological biochemical mechanisms involved process. For this, authors conducted two experiments: one with other Treatments were arranged randomized blocks 5 replications, 2 × factorial scheme. Factors consisted absence (-Si) presence (+ Si) spraying; regimes: 70% (without deficit) 30% (severe retention Silicon was supplied during formation presprouted seedlings pots filled samples Entisol (Quartzipsamment). In pots, regimes induced 7 160 days transplanting.

Despite the recent need for sustainable energy resources, bioenergy gained its spotlight in 2000s. Sugarcane is a significant crop terms of sugar and capacity, it can be an alternative source to mitigate effects climate change. Bioenergy production from sugarcane Brazil one most efficient options. This lends centrality biofuels’ importance confronting change effects. The present article reviews Brazilian history this as biofuel source, focusing on plants biomass. We highlight historical changes related scientific, technological, industrial, environmental advances since beginning 20th century. describe how creating governmental institutes disseminating scientific knowledge strengthened public policies that led occupy leadership positions producing, distributing, using throughout country. compiled data show improvements new approaches needed improve ethanol use. performed bibliometric analysis evaluate science’s contribution process compared other countries. Brazil’s science investment development transportation may divided into two phases: ethanol-only flex-fuel cars. A third phase starting, directed SAF ethanol-to-hydrogen era.

Biotic and abiotic stresses are the foremost limiting factors for crop productivity. Crop plants need to cope with adverse external pressure caused by various environmental conditions their intrinsic biological mechanisms keep growth, development, Climate-resilient, pest resistance high-yielding crops be developed maintain sustainable food supply. Over last decade, understanding of genetic complexity agronomic traits in sugarcane has prompted integrated application engineering address specific questions. Genes adaptation stress, yield enhancement being determined introgressed develop elite cultivars improved characteristics through approaches.

Sugarcane is a C4 and agro-industry-based crop with high potential for biomass production. It serves as raw material the production of sugar, ethanol, electricity. Modern sugarcane varieties are derived from interspecific intergeneric hybridization between Saccharum officinarum, spontaneum, other wild relatives. breeding programmes broadly categorized into germplasm collection characterization, pre-breeding genetic base-broadening, varietal development programmes. The identification through classic programme requires minimum 12-14 years. precise phenotyping in extremely tedious due to propensity lodging suckering owing influence environmental factors management practices. This kind data both plant ratoon experiments conducted over locations seasons. In this review, we explored feasibility genomic selection schemes various sugarcane. diversity analysis using genome-wide markers helps formation core set representing total present gene bank. association studies prediction bank helpful identify complete resources cane yield, commercial tolerances biotic abiotic stresses, agronomic traits. implementation pre-breeding, base-broadening assist introgression specific genes recurrent enhance higher frequency favorable alleles population considerable reduction cycles size. integration covariates multi-environment trials assists performance different agro-climatic zones. review also directed its focus on enhancing gain time, cost, resource allocation at stages
