“…The sunflower (Helianthus annuus L.) has great importance in the world economy as one of the most cultivated oilseed crops (Castro;Leite, 2018). Sunflower seeds contain 38% to 50% oil, which is widely used in human food and the production of biodiesel (Miladinović et al, 2019). The average productivity of sunflower crops in the worldwide was 1803.9 kg/ha in 2019 (FAO, 2019).…”

Drought is the most harmful environmental factor crop productivity. Some chemicals are used in agriculture to mitigate the damage from this stress on plants. Therefore, we examined whether the spraying of zinc sulfate (ZS), potassium phosphite (KPhi) and the hydrogen sulfide (H2S) donor sodium hydrosulfide (NaHS) would mitigate the deleterious effects of water deficit on sunflower plants by analyzing physiological and biometric characteristics. The experiment was carried out in a greenhouse using a randomized block design with five replications. The treatments were arranged in a 4 x 2 factorial scheme: [Factor A (Alleviators)] - spraying of KPhi (0.5 L ha-1), ZS (3.2 kg ha-1), NaHS (1.2 g ha-1), and water; [Factor B (substrate humidity, SH)] - 100% (well irrigated) and 30% (water deficit, WD) of field capacity. Under WD conditions, alleviators led to the maintenance of higher values of water potential (ΨW), a lower content of leaf malonaldehyde (MDA), and increased activity of the antioxidant enzyme peroxidase (POX), except for ZS. However, leaf osmotic potential, proline concentration, variables related to gas exchange and chlorophyll a fluorescence, and biometric characteristics differed only according to the SH factor. The results of ΨW and MDA for sunflower plants under WD are indicative of the mitigating capacity of ZS, KPhi, and H2S. Thus, the spraying of these compounds on sunflower plants mitigates the effects of WD, acting specifically in physiological processes related to antioxidant responses and in the maintenance of water in leaf tissues.

“…As in genetic transformation, regeneration efficiency could be a bottleneck for the effective deployment of GE techniques in crop breeding (Miladinović et al 2019). Many crops such as cotton and sunflower are either recalcitrant or have difficult and long transformation protocols (Taški-Ajduković et al 2010;Gao et al 2017).…”

Key message This review illustrates how far we have come since the emergence of GE technologies and how they could be applied to obtain superior and sustainable crop production. Abstract The main challenges of today’s agriculture are maintaining and raising productivity, reducing its negative impact on the environment, and adapting to climate change. Efficient plant breeding can generate elite varieties that will rapidly replace obsolete ones and address ongoing challenges in an efficient and sustainable manner. Site-specific genome editing in plants is a rapidly evolving field with tangible results. The technology is equipped with a powerful toolbox of molecular scissors to cut DNA at a pre-determined site with different efficiencies for designing an approach that best suits the objectives of each plant breeding strategy. Genome editing (GE) not only revolutionizes plant biology, but provides the means to solve challenges related to plant architecture, food security, nutrient content, adaptation to the environment, resistance to diseases and production of plant-based materials. This review illustrates how far we have come since the emergence of these technologies and how these technologies could be applied to obtain superior, safe and sustainable crop production. Synergies of genome editing with other technological platforms that are gaining significance in plants lead to an exciting new, post-genomic era for plant research and production. In previous months, we have seen what global changes might arise from one new virus, reminding us of what drastic effects such events could have on food production. This demonstrates how important science, technology, and tools are to meet the current time and the future. Plant GE can make a real difference to future sustainable food production to the benefit of both mankind and our environment.

Background: Sunflower is an important oilseed crop domesticated in North America approximately 4000 years ago. During the last century, oil content in sunflower was under strong selection. Further improvement of the oil properties achieved by modulating its fatty acid composition is one of the main directions in modern oilseed crop breeding. Results: We searched for the genetic basis of fatty acid content variation by genotyping 601 inbred sunflower lines and assessing their lipid and fatty acid composition. Our genome-wide association analysis based on the genotypes of 15,483 SNPs and the concentrations of 23 fatty acids, including minor fatty acids, revealed significant genetic associations for eleven of them. Identified genomic regions included novel loci on chromosomes 3 and 14 cumulatively, explaining up to 34.5% of the total variation of docosanoic acid (22:0) in sunflower oil.Conclusions: This is the first large scale implementation of high-throughput lipidomic profiling on sunflower germplasm characterization. This study contributes to the genetic characterization of Russian collections, which made a substantial contribution to the development of a sunflower as the oilseed crop worldwide and provides new insights into the genetic control of oil composition that can be implemented in future studies.
