“…In recent decades, researchers have devoted significant attention to enhancing the quality and quantity of seed oils for both food and non-food purposes, as well as exploring new oil sources (Subedi et al, 2020a and b;Bhati et al, 2021;Chen et al, 2021a;Sheri et al, 2021). The fatty acid composition of plant oils plays a crucial role in determining their quality and suitability for various applications, primarily by distinguishing between saturated and unsaturated FA.…”

As climate change intensifies and the need to reduce human-caused emissions becomes more urgent, transitioning to a bio-based economy is essential. This paper explores the diverse industrial applications of plant oils as sustainable alternatives to petroleum-based products, including their use in food, polymers, lubricants, surfactants, pesticides, emollients, and biofuels. This review delves into biosynthetic pathways, detailing the key enzymes and processes involved in the synthesis of triacylglycerol. It thoroughly discusses how genetic and metabolic engineering can not only increase oil yields but also modify fatty acid compositions to better meet industrial requirements. By understanding genetics and utilizing advanced biotechnologies, the oil content and quality of plant sources can be significantly enhanced, aligning with both sustainability goals and industrial demands. This paper provides a comprehensive overview of the current uses and genetic engineering of plant oil production, proposing innovative strategies such as utilizing oils from biomass or cultivating non-edible oil crops. These approaches aim to establish a sustainable industrial system, reduce reliance on fossil fuels, and promote the growth of an environmentally responsible bio-based economy. Additionally, the review highlights future directions, examining the economic implications and environmental benefits of adopting plant oils across various sectors and positioning them as pivotal to achieving an eco-friendly, bio-based economy.

“…Therefore, breeding for drought and salinity-tolerant cultivars will contribute to the expansion of the sunflower into marginal areas and consequently increase the stability of the global supply of sunflowers. The availability of sunflower regeneration systems and gene editing techniques make it possible to breed drought and salt-tolerant sunflower cultivars ( Darqui et al, 2021 ; Kumar et al, 2023 ; Li et al, 2021 ; Sheri, Muddanuru & Mulpuri, 2021 ). However, this requires finding genes that confer salt and drought tolerance to the plant.…”

In the context of global climate change, drought and soil salinity are some of the most devastating abiotic stresses affecting agriculture today. PYL proteins are essential components of abscisic acid (ABA) signaling and play critical roles in responding to abiotic stressors, including drought and salt stress. Although PYL genes have been studied in many species, their roles in responding to abiotic stress are still unclear in the sunflower. In this study, 19 HaPYL genes, distributed on 15 of 17 chromosomes, were identified in the sunflower. Fragment duplication is the main cause of the expansion of PYL genes in the sunflower genome. Based on phylogenetic analysis, HaPYL genes were divided into three subfamilies. Members in the same subfamily share similar protein motifs and gene exon-intron structures, except for the second subfamily. Tissue expression patterns suggested that HaPYLs serve different functions when responding to developmental and environmental signals in the sunflower. Exogenous ABA treatment showed that most HaPYLs respond to an increase in the ABA level. Among these HaPYLs, HaPYL2a, HaPYL4d, HaPYL4g, HaPYL8a, HaPYL8b, HaPYL8c, HaPYL9b, and HaPYL9c were up-regulated with PEG6000 treatment and NaCl treatment. This indicates that they may play a role in resisting drought and salt stress in the sunflower by mediating ABA signaling. Our findings provide some clues to further explore the functions of PYL genes in the sunflower, especially with regards to drought and salt stress resistance.

“…Sunflower ( Helianthus annuus L.) is a widely cultivated crop mainly used for the production of oil and confectionary products [ 32, 33 ]. Despite its agricultural significance, it has been traditionally considered a challenging species for transformation [ 34 , 35 , 36 , 37 ]. In the field of VIGS, only a few studies on sunflowers have been conducted recently.…”

Virus-Induced Gene Silencing (VIGS) is a versatile tool in plant science, yet its application to non-model species like sunflower demands extensive optimization due to transformation challenges. In this study, we aimed to elucidate the factors that significantly affect the efficiency of Agrobacterium-VIGS in sunflowers. After reaffirming a number of approaches, we concluded that the seed vacuum technique followed by 6 h of co-cultivation produced the most efficient VIGS results. Genotype-dependency analysis revealed varying infection percentages (62-91%) and silencing symptom spreading in different sunflower genotypes. Additionally, we explored the mobility of tobacco rattle virus (TRV) and phenotypic silencing manifestation (photo-bleaching) across different tissues and regions of VIGS-infected sunflower plants. We showed the presence of TRV is not necessarily limited to tissues with observable silencing events. Finally, time-lapse observation demonstrated a more active spreading of the photo-bleached spots in young tissues compared to mature ones. This study not only offers a robust VIGS protocol for sunflowers but also provides valuable insights into genotype-dependent responses and the dynamic nature of silencing events, shedding light on TRV mobility across different plant tissues.
