“…The conditioning of plants to stress is an important feature for enhancing crop resilience and reducing productivity losses due to abiotic and biotic stresses (Kerchev et al, 2019). Plant conditioning is based on the molecular activation and priming of plant molecular defense systems so enhanced plant tolerance is exhibited upon subsequent stress occurrences (Martinez-Medina et al, 2016).…”

Phaeophyceaean (Brown Algal) Extracts Activate Plant Defense Systems in Arabidopsis thaliana Challenged With Phytophthora cinnamomi

Seaweed extracts are important sources of plant biostimulants that boost agricultural productivity to meet current world demand. The ability of seaweed extracts based on either of the Phaeophyceaean species Ascophyllum nodosum or Durvillaea potatorum to enhance plant growth or suppress plant disease have recently been shown. However, very limited information is available on the mechanisms of suppression of plant disease by such extracts. In addition, there is no information on the ability of a combination of extracts from A. nodosum and D. potatorum to suppress a plant pathogen or to induce plant defense. The present study has explored the transcriptome, using RNAseq, of Arabidopsis thaliana following treatment with extracts from the two species, or a mixture of both, prior to inoculation with the root pathogen Phytophthora cinnamomi. Following inoculation, five time points (0−24 h post-inoculation) that represented early stages in the interaction of the pathogen with its host were assessed for each treatment and compared with their respective water controls. Wide scale transcriptome reprogramming occurred predominantly related to phytohormone biosynthesis and signaling, changes in metabolic processes and cell wall biosynthesis, there was a broad induction of proteolysis pathways, a respiratory burst and numerous defense-related responses were induced. The induction by each seaweed extract of defense-related genes coincident with the time of inoculation showed that the plants were primed for defense prior to infection. Each seaweed extract acted differently in inducing plant defense-related genes. However, major systemic acquired resistance (SAR)-related genes as well as salicylic acid-regulated marker genes (PR1, PR5, and NPR1) and auxin associated genes were found to be commonly up-regulated compared with the controls following treatment with each seaweed extract. Moreover, each seaweed extract suppressed P. cinnamomi growth within the roots of inoculated A. thaliana by the early induction of defense pathways and likely through ROS-based signaling pathways

“…Stress caused by water scarcity is one of the most important factors limiting crop yields. Reports on biochemical and physiological studies of drought resistance are regularly summarized in the reviews (Foyer and Noctor 2009;Jogaiah et al 2013;Wani et al 2016;Kerchev et al 2019). It is generally accepted that maintaining cell membranes integrity and stability under water stress conditions is a major component of drought tolerance in plants (Bajji et al 2001;Quan et al 2004;Liu et al 2019).…”

The effectiveness of exogenously applied zearalenone (ZEN) in alleviating water deficiency stress of pea (Pisum sativum L.) and yellow lupine (Lupinus luteus L.) was analyzed in the pot experiment. ZEN was applied in the form of spraying in the flowering phase on the first day of induced drought. The effectiveness of ZEN was evaluated based on physiological (electrolyte leakage, greenness, and photosystem II activity) and biochemical (protein, proline, ascorbic acid contents, and antioxidant enzyme activity) parameters after 14 days of drought. The yield and yield quality defined as yield components, total protein, fats, sugars, and antioxidants (tocopherols and β-carotene) were measured in newly formed seeds. ZEN residue in the seeds was analyzed employing UHPLC-MS/MS to exclude its accumulation. The results showed the possibility of reducing the effects of drought stress through the use of ZEN. It was manifested by increased cell membranes stability and antioxidant enzyme activity and above all ZEN increased crop yield, compared to untreated plants. ZEN modified seed composition by inducing the accumulation of fats and antioxidants. There was no accumulation of exogenous ZEN in seeds.

“…Recently, GABA has gained attention as a priming agent (Jalil and Ansari, 2020). Plant priming or conditioning is a promising strategy in which the plant's physiological state is intentionally altered by natural products or synthetic chemicals to promote a more effective defense response in the case of subsequent harsher stresses (Kerchev et al, 2020). When the plant reaches the "primed" state, broad-spectrum defense is partially induced by activating defense genes, changing the proteome profile and accumulating defense compounds, among other processes, minimizing the corresponding negative effects on crop productivity (Vijayakumari et al, 2016).…”

Challenges and Prospects of New Plant Breeding Techniques for GABA Improvement in Crops: Tomato as an Example

Over the last seven decades, g-aminobutyric acid (GABA) has attracted great attention from scientists for its ubiquity in plants, animals and microorganisms and for its physiological implications as a signaling molecule involved in multiple pathways and processes. Recently, the food and pharmaceutical industries have also shown significantly increased interest in GABA, because of its great potential benefits for human health and the consumer demand for health-promoting functional compounds, resulting in the release of a plethora of GABA-enriched products. Nevertheless, many crop species accumulate appreciable GABA levels in their edible parts and could help to meet the daily recommended intake of GABA for promoting positive health effects. Therefore, plant breeders are devoting much effort into breeding elite varieties with improved GABA contents. In this regard, tomato (Solanum lycopersicum), the most produced and consumed vegetable worldwide and a fruit-bearing model crop, has received much consideration for its accumulation of remarkable GABA levels. Although many different strategies have been implemented, from classical crossbreeding to induced mutagenesis, new plant breeding techniques (NPBTs) have achieved the best GABA accumulation results in red ripe tomato fruits along with shedding light on GABA metabolism and gene functions. In this review, we summarize, analyze and compare all the studies that have substantially contributed to tomato GABA breeding with further discussion and proposals regarding the most recent NPBTs that could bring this process to the next level of precision and efficiency. This document also provides guidelines with which researchers of other crops might take advantage of the progress achieved in tomato for more efficient GABA breeding programs.
