“…However, several authors correlated these effects to the potential intensification of plant enzymatic systems to the biostimulant chelating metal activity, or to their auxin- and gibberellin-like activity [ 12 , 19 ]. In particular, it was recently reported in the literature that the application of seaweed-based biostimulants on crop plants could lead not only to enhanced root development [ 27 ], biomass accumulation [ 19 , 26 ], and triggering in flowering and fruit set [ 48 ], but also to improved fruit yield and large sized fruits with superior quality [ 19 , 49 ].…”

“…Micro-Tom) produced by plants grown in standard conditions. Seaweed and yeast extracts are receiving a greater acceptance in horticulture as plant biostimulants due to several beneficial effects against abiotic stresses [ 17 , 26 , 27 , 28 ]. However, the effects deriving from the application of biostimulants based on the combination of seaweed and yeast extracts on tomato fruit quality grown under standard conditions are scarcely available in the literature.…”

Plant biostimulants are under investigation as innovative products to improve plant production and fruit quality, without resulting in environmental and food contaminations. Here, the effects of the application of Expando, a biostimulant based on seaweed and yeast extracts, on plant productivity, fruit ripening times, and fruit quality of Solanum lycopersicum var. Micro-Tom were evaluated. After biostimulant treatment, a two-week reduction of ripening times and a concomitant enhancement of the production percentage during the earliest ripening times, in terms of both fruit yield (+110%) and size (+85%), were observed. Concerning fruit quality, proximate analysis showed that tomatoes treated with the biostimulant had better nutritional composition compared to untreated samples, since both the quality of unsatured fatty acids (C16:3ω3: +328%; C18:2ω6: −23%) and micronutrients essential for human health (Fe: +14%; Cu: +21%; Zn: +24%) were increased. From a nutraceutical point of view, despite strong changes in bioactive compound profile not being observed, an increase of the antioxidant properties was recorded in fruits harvested by plants treated with the biostimulant (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS): +38%; 2,2-diphenyl-1-picrylhydrazyl (DPPH): +11%). In conclusion, the biostimulant application was able to reduce the ripening times and fruit size, while slightly increasing nutritional and nutraceutical values, leading to more marketable tomato fruits.

“…The effect of Kappaphycus alvarezii extract applied to the soil was analyzed on maize plants under drought stress (no irrigation for 10 days) ( Kumar et al, 2019 ). To obtain a global view of the effect, the authors analyzed the transcriptome of the roots of the plants 10 days after the application of the treatment.…”

Transcriptomics of Biostimulation of Plants Under Abiotic Stress

Plant biostimulants are compounds, living microorganisms, or their constituent parts that alter plant development programs. The impact of biostimulants is manifested in several ways: via morphological, physiological, biochemical, epigenomic, proteomic, and transcriptomic changes. For each of these, a response and alteration occur, and these alterations in turn improve metabolic and adaptive performance in the environment. Many studies have been conducted on the effects of different biotic and abiotic stimulants on plants, including many crop species. However, as far as we know, there are no reviews available that describe the impact of biostimulants for a specific field such as transcriptomics, which is the objective of this review. For the commercial registration process of products for agricultural use, it is necessary to distinguish the specific impact of biostimulants from that of other legal categories of products used in agriculture, such as fertilizers and plant hormones. For the chemical or biological classification of biostimulants, the classification is seen as a complex issue, given the great diversity of compounds and organisms that cause biostimulation. However, with an approach focused on the impact on a particular field such as transcriptomics, it is perhaps possible to obtain a criterion that allows biostimulants to be grouped considering their effects on living systems, as well as the overlap of the impact on metabolism, physiology, and morphology occurring between fertilizers, hormones, and biostimulants.

“…In this research, the impact of the applied A. nodosum filtrate depended on the stress level. R. Kumar, Trivedi, Anand, and Ghosh (2020) reported the upregulation of the genes coding towards the enhancement of maize root growth, gibberellic acid and auxin signalling, seed development, nitrogen metabolism, transport and antioxidant activity like glutathione S‐transferase and peroxidases, elicited by the application of K‐sap ( Kappaphycus alvarezii seaweed extract). The authors concluded that the enhanced N metabolism‐related transcripts might lead to higher nitrogen content under drought conditions, in all the maize plant parts including grains.…”

Plants must cope with different environmental stresses during their whole lifetime. Abiotic stresses like drought, salt, mineral nutrition disturbances and temperature stress are commonly interconnected through some physiological events in stressed plants, such as the synthesis of protective plant compounds as a response to stress. Many of these, produced within plant primary or secondary metabolism, act as functional compounds not exclusively in plants but in other organisms as well. Concurrently, many of the active compounds in biostimulants which can support plant stress tolerance and productivity in adverse growth conditions are the metabolites or intermediates that may influence the plant's edible parts nutritional quality. Such effects of biostimulants application are not elucidated enough, therefore, we aimed to give an overview of recent advances in the research related to the interplay among abiotic stress, plant response, biostimulants effects and plant‐derived functional food, focusing on plant metabolites as the link which connects the environment with the food chain.
