Plants naturally produce various substances of different chemical nature, which represent the products of primary and secondary plant metabolism. Primary metabolites such as carbohydrates, amino acids, fatty acids, and organic acids are required for processes of plant growth and development. Products obtained from primary metabolites and produced by biosynthetic modifications into more complex structural composition are considered secondary metabolites; these include flavonoids, carotenoids, sterols, phenolic acids, alkaloids, and glucosinolates. They are responsible for the color of fruits, protection against herbivores and microorganisms, and the attraction of pollinators and seed-dispersing animals, and act as signal molecules in stress conditions.
The biological functions of many metabolites are still widely unrecognized in plants due to their frequently low concentrations, so emerging challenges in plant biology primarily include the selection of appropriate methods for the extraction of compounds of interest and their subsequent quantification. Recently, the application of advanced analytical methods such as chromatography, mass spectrometry, infrared spectrometry, nuclear magnetic resonance, etc. has enabled quantitative and qualitative research in metabolomics. Even so, knowledge regarding a huge number of plant metabolites is still obscure, and their functions remain unknown. Therefore, this Special Issue focuses on the qualitative and quantitative evaluation of different classes of metabolites with broad activities in plant tissues. We welcome both review and original research articles.

Abstract: Abstract: This study aimed to investigate the effect of cultivar, microbiological fertiliser and season on the phenolics and sesquiterpene lactones content in lettuce. Plants were grown in the greenhouse using two microbiological fertilisers (EM Aktiv and Vital Tricho), and their combination. Experiments were organized in three consecutive growing seasons (autumn, winter and spring) with six red and green cultivars. Red cultivars showed higher phenolics and lactones content compared to green. Chicoric acid and luteolin-7-glucoside were the most abundant phenolics found in red cultivar ‘Gaugin’ in winter trial. Fertiliser EM Aktiv and Vital Tricho led to significantly higher phenolic acids content in a range of 29.2-75.0%. On contrary, application of single fertilisers had no effect, or their combination even lowered flavonoids content. Generally, lactones were accumulated during autumn, whereas phenolics in winter, with few exceptions. Total phenolics content, caffeoylmalic acid and quercetin-3-malonylglucoside-7-glucoside were higher in autumn while chlorogenic, neochlorogenic acid and dihydrolactucopicrin in spring. Lactucopicrin was predominant lactone among tested cultivars with highest value in red cultivar ‘Carmesi’. Combined fertilisers led to significantly increased lactones content by 40-200% in autumn. Sensory analysis showed negative correlation between taste and total sesquiterpene lactones, lactucopicrin, caffeoylmalic and chlorogenic acid, indicating less bitter taste with decreasing content of these compounds. Our findings indicate that cultivar, fertiliser and growing season jointly affected all of the tested parameters highlighting the importance of application of EM Aktiv and/or combined fertilisers.
