“…This is valuable because it highlights that compounds in plant extracts can affect the biosynthesis pathway of plant growth regulators in speci c concentrations, as shown in the results of the present study. For example, coumaric acid is one of the dominant and important compounds in dandelion (Piccolella et al 2023), and it has the ability to transform into salicylic acid in its biochemical pathway (Taiz et al 2015). Salicylic acid can act as a stimulant in low concentration and as a growth inhibitor in high concentration (Horvath et al 2007).…”

Medicinal plants and their derivatives have been used for centuries in various sectors beyond treatment and nutrition. However, the use of toxic chemicals such as pesticides, fungicides, and herbicides has led to environmental pollution, necessitating the search for eco-friendly alternatives. Medicinal plants and their compounds offer a promising solution due to their naturalness and biodegradability. An in-vitro experiment was conducted at Gorgan University in 2022 to test the impact of six medicinal plant extracts on tomato growth and callus induction. Two concentrations of 50 and 100 mg/L were added to the Murashige and Skoog (MS) medium culture. Results showed a 100% increase in germination speed and an increasing trend in stem length (SL), with the 50 mg/L Juniperus sabina treatment yielding the highest amount. The amount of callus growth (CG) and weight (CW) increased by 50% and over 200%, respectively, with the Taraxacum officinale 100 and Conocarpus erectus 50 mg/L treatments producing the best results. More than 90% callus formation was observed compared to the control. Biochemical analysis revealed that the extracts were rich in phenolic compounds (348 mg/g of total phenol), flavonoids (162 mg/g), antioxidants (61%), and auxin. Antioxidant and plant growth regulators (PGR) content and the stimulation of the plant's defense system likely contributed to the results. Plant extracts also affected the biochemical content of calluses, with the exception of total phenol. Using plant extracts to increase growth and reduce time for callus induction is recommended in tomato tissue culture. However, optimal concentration and combination of medicinal plant extracts for different plant species and growth conditions require further research.

“…This realization has sparked a crucial sustainability principle: the valorization of waste materials. Furthermore, rubber seeds are particularly rich in bioactive compounds [8]. They contain a variety of phytochemicals, including polyphenols, flavonoids, and tannins, which are known for their antioxidant properties [9].…”

“…In light of this, waste valorization becomes a commendable strategy for the global community, aligning with broader sustainability objectives by promoting efficient resource use, reducing waste generation, and potentially fostering economic opportunities from materials that were once considered mere byproducts [10]. Furthermore, rubber seeds are particularly rich in bioactive compounds [8]. They contain a variety of phytochemicals, including polyphenols, flavonoids, and tannins, which are known for their antioxidant properties [9].…”

Valorizing natural resources through sustainable and eco-friendly processes is a cornerstone in pursuing a greener and more sustainable future. This study focuses on the green extraction of valuable compounds from rubber seed trees (Hevea brasiliensis). This underutilized resource has the potential to yield bioactive compounds of economic and ecological significance. We explore the application of environmentally friendly extraction techniques, including supercritical fluid extraction (SFE), microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE), to harness the bioactive potential of rubber seeds. Our research encompasses a comprehensive analysis of the extracted compounds, including their characterization and quantification using state-of-the-art analytical techniques. Environmental and economic sustainability aspects are evaluated, shedding light on the green extraction processes’ ecological footprint and economic feasibility. The paper also delves into these extracted compounds’ diverse applications and utilization prospects, ranging from pharmaceuticals and nutraceuticals to cosmetic and industrial products. We discuss the commercial potential, market opportunities, and emerging trends these sustainable endeavours may shape. In conclusion, this study paves the way for a more sustainable path in harnessing valuable compounds from rubber seed trees, exemplifying the potential for green extraction techniques to play a pivotal role in the journey toward environmental stewardship and economic prosperity.

“…Inulin (Figure 1B) is the main storage carbohydrate in dandelions [30] and inulin carbon, if necessary, can be redirected towards rubber biosynthesis through acetyl-CoA, which occurs in nature towards the end of the growing season [31]. One study showed that in addition to rubber and inulin, TKS contains a wide variety of valuable metabolites, such as sesquiterpenoids, fatty acids and their derivatives, and phenolic compounds (caftaric and chicoric acids) [32]. It was pointed out that TKS leaves are a valuable source of chicoric acid, with potential use as an antioxidant for use as herbal medicine and nutrition for health food/fodder production [33].…”

Natural rubber (NR) remains an indispensable raw material with unique properties that is used in the manufacture of a large number of products and the global demand for it is growing every year. The only industrially important source of NR is the tropical tree Hevea brasiliensis (Willd. ex A.Juss.) Müll.Arg., thus alternative sources of rubber are required. For the temperate zone, the most suitable source of high quality rubber is the Russian (Kazakh) dandelion Taraxacum kok-saghyz L.E. Rodin (TKS). An obstacle to the widespread industrial cultivation of TKS is its high heterozygosity, poor growth energy, and low competitiveness in the field, as well as inbreeding depression. Rapid cultivation of TKS requires the use of modern technologies of marker-assisted and genomic selection, as well as approaches of genetic engineering and genome editing. This review is devoted to describing the progress in the field of molecular genetics, genomics, and genetic engineering of TKS. Sequencing and annotation of the entire TKS genome made it possible to identify a large number of SNPs, which were subsequently used in genotyping. To date, a total of 90 functional genes have been identified that control the rubber synthesis pathway in TKS. The most important of these proteins are part of the rubber transferase complex and are encoded by eight genes for cis-prenyltransferases (TkCPT), two genes for cis-prenyltransferase-like proteins (TkCPTL), one gene for rubber elongation factor (TkREF), and nine genes for small rubber particle proteins (TkSRPP). In TKS, genes for enzymes of inulin metabolism have also been identified and genome-wide studies of other gene families are also underway. Comparative transcriptomic and proteomic studies of TKS lines with different accumulations of NR are also being carried out, which help to identify genes and proteins involved in the synthesis, regulation, and accumulation of this natural polymer. A number of authors already use the knowledge gained in the genetic engineering of TKS and the main goal of these works is the rapid transformation of the TKS into an economically viable rubber crop. There are no great successes in this area so far, therefore work on genetic transformation and genome editing of TKS should be continued, considering the recent results of genome-wide studies.
