Drought is considered the major abiotic stress limiting crop productivity. This study seeks to identify proteins involved in the drought response in sugarcane stems submitted to drought stress. The integration of nuclei enrichment sample preparation with the shotgun proteomic approach results in great coverage of the sugarcane stem proteome with 5381 protein groups identified. A total of 1204 differentially accumulated proteins are detected in response to drought, among which 586 and 618 are increased and reduced in abundance, respectively. A total of 115 exclusive proteins are detected, being 41 exclusives of drought-stressed plants and 74 exclusives of control plants. In the control plants, most of these proteins are related to cell wall metabolism, indicating that drought affects negatively the cell wall metabolism. Also, 37 transcription factors (TFs) are identified, which are low abundant nuclear proteins and are differentially accumulated in response to drought stress. These TFs are associated to protein domains such as leucine-rich (bZIP), C2H2, NAC, C3H, LIM, Myb-related, heat shock factor (HSF) and auxin response factor (ARF). Increased abundance of chromatin remodeling and RNA processing proteins are also observed. It is suggested that these variations result from an imbalance of protein synthesis and degradation processes induced by drought.

“…The silicon also induced a lower leaf water loss due to a possible reduction in the tension of the xylem solution that is transmitted through continuous water columns to the roots (Marcos et al 2018), which in turn may have reflected in the equilibrium of leaf water potential. The effect of Si on increasing water potential resulted in higher water content in wheat seedlings (Gong et al 2003), in corn plants (Amin et al 2014;Kaya et al 2006), and in sugarcane (Camargo et al 2019).…”

This study is aimed at assessing whether silicon (Si) can mitigate the effects caused by water stress in pre-sprouted seedlings (PSS) in sugarcane after their transplanting in the soil and what is the best form in the application if via nutrient solution or leaf spraying. The treatments were arranged in a 3 × 3 factorial scheme with silicon supply via nutrient solution (2 mmol L −1), Si via leaf application (3.4 mmol L −1), and without Si (control) and three levels of soil water retention capacity (70%, 50%, and 30%), for 30 days. In the absence of Si, the water deficit was damaging to the physiological, growth, and dry matter production variables of plants, in a 30% level of soil water retention capacity. Silicon supply via nutrient solution was more efficient when compared with Si via leaf spraying in the formation of pre-sprouted sugarcane seedlings in the first 30 days after transplanting, since it increased the quantum efficiency of photosystem II, chlorophyll content, leaf water potential, and water content, decreased cell electrolyte leakage and free proline content, and allowed a higher growth and biomass production. In conclusion, the supply of Si via nutrient solution in pre-sprouted sugarcane seedlings can be considered a feasible alternative to alleviate water deficit damage imposed after transplanting, in a 30% level of soil water retention capacity.

“…Proline has been shown to have a strong correlation with increased drought tolerance (Balestro et al, 2017;Castañeda et al, 2018). However, Mansour and Ali (2017), and Marcos et al (2018) argued that since proline is produced under stressful conditions, its absence or low production by the plant may indicate less stress.…”

“…Water deficit is one of the main factors against crop production (Ferreira et al, 2017), but not the only one, since other types of stress are capable of causing damage and organicity, cellular (Maia et al, 2012). Aiming at favorable conditions, plants may produce several antioxidant enzymes and other non-enzymatic compounds that seek to neutralize stress-induced damage (Cia et al, 2012;Marcos et al, 2018).…”

“…As a defense mechanism against unfavorable conditions, plants produce antioxidant enzymes and other non-enzymatic compounds that are able to neutralize the damage caused due to stress (Jiang et al, 2016;Marcos et al, 2018). Antioxidative enzymes include catalase, superoxide dismutase, ascorbate peroxidase, polyphenoloxidase, peroxidase and glutathione reductase (Moura et al, 2018…”

The objective of this research was to evaluate the productive response associate to biochemical indicators and oxidative enzymes activities involved in the water deficit resistance in eight sugarcane varieties (RB951541, RB931011, RB962962, RB867515, RB763710, RB72454, RB863129, and RB92579) grown in the semi-arid regions of Brazil. Compared to all other varieties, RB763710 was superior in the number of stems m-1, mean height, and stem diameter, production of whole plant fresh biomass and stem. When biochemical responses were obtained, all sugarcane varieties had a statistically similar solubility and maturity, regardless of the specific maturity rate of each cultivar. The increase in soluble carbohydrate levels occurred in the most stress-sensitive varieties and the variety RB763710 had the highest proline content. A lower general correlation was observed between the production of fresh biomass of stalks and the enzymatic activity. Among the varieties, RB763710 had the highest enzymatic activities which possibly provided greater tolerance to water stress due to the ability to maintain the redox state in the leaves of plants under water deficit. The study of the adaptation mechanisms of sugarcane against water deficit has contributed to the development and diffusion of genotypes tolerant to rainfed conditions, thus contributing to increased productivity even under adverse conditions, allowing maintenance and optimization of the production chains of sugarcane in rainfed regions.
