“…This wild species has effective resistance mechanisms to different abiotic stress factors, but also to some biotic agents, like aphids (Alvarez et al, 2006), nematodes (Austin et al, 1993) or fungi (Lokossou et al, 2010). In this context, higher TPC, TFC and AA were actually expected for the wild species, all three physiological traits taken into consideration being actively involved in the resistance mechanisms (Lattanzio et al, 2006;Mierziak et al, 2014).…”

“…maintaining the redox state of the cell are the phenolic compounds, due to their strong antioxidant capacity. Phenols may be found constitutively in plant cells, but it was demonstrated that their quantity is rapidly increasing, by de novo synthesis, in the presence of a stressful factor (JacoboVelázquez and Cisneros-Zevallos, 2012; Mierziak et al, 2014). In this way, phenolic compounds are directly involved in the plant defence mechanisms and in overcoming abiotic stress conditions (Ramakrishna and Ravishankar, 2011).…”

Phenols, important secondary metabolites in plants, are responsible for specific defence mechanisms against abiotic stress, due to their strong antioxidant activity. Flavonoids, as part of phenolic group, are also involved in plant stress responses, being primarily responsible for photo-protection against UV solar radiation. Based on these premises, the plant response to optimized in vitro culture was evaluated, by quantifying the total polyphenolic content, the total flavonoid content and the antioxidant activity, both under in vitro and ex vitro conditions. Four closely related potato genotypes were analysed: the wild species Solanum bulbocatanum, S. tuberosum cv. 'Rasant' and two somatic hybrids between them. For all genotypes, both total polyphenolic content and antioxidant activity were increasing under optimized in vitro culture. The shoot responses were genotype dependent and the two somatic hybrids were intermediate between the parents both as morphology and reaction to in vitro stress. The somatic hybrid 1508/5, having morphology similar to potato, was reacting as the wild species, while the somatic hybrid 1508/2, with a similar morphology to the wild species was reacting as potato to in vitro stress. The somatic hybrid 1508/5 being also resistant to late blight is of interest for further use in pre-breeding. Total flavonoid content is decreasing under in vitro as compared to ex vitro conditions, UV-B radiation, the major trigger of flavonoid biosynthesis being absent in the fluorescent light. This study reveals the effect of in vitro culture on flavonoid content and details aspects of the biochemical parameters involved in plant in vitro stress.

“…57 Flavonoids are implicated in many important functions in plant including signaling to symbiotic bacteria and they may play an important role in plant resistance against pathogenic bacteria and fungi. 58 Flavonoids may enhance plant resistance to pathogens in several different ways: (1) by quenching the reactive oxygen species which form in plants after infection, (2) by inhibition of pathogen's digestive enzymes as a result of chelating metals required for their activity, (3) by induction of the hypersensitivity reaction and programmed cell death, (4) and by tightening of the plant cell structure by altering indole-3-acetic acid activity. 59 In addition, flavonoids, can stimulate or inhibit insect feeding and oviposition.…”

Currently, the global citrus production is declining due to the spread of Huanglongbing (HLB). HLB, otherwise known as citrus greening, is caused by Candidatus Liberibacter asiaticus (CLas) and is transmitted by the Asian citrus psyllids (ACP), Diaphorina citri Kuwayama. ACP transmits CLas bacterium while feeding on the citrus phloem sap. Multiplication of CLas in the phloem of citrus indicates that the sap contains all the essential nutrients needed for CLas. In this study, we investigated the micro-and macro-nutrients, nucleotides, and others secondary metabolites of phloem sap from pineapple sweet orange. The micro-and macro-nutrients were analyzed using inductively coupled plasma-mass spectroscopy (ICP-MS) and inductively coupled plasma-optical emission spectroscopy (ICP-OES). Nucleotides and other secondary metabolites analysis was accomplished by reversed phase HPLC coupled with UV, fluorescence detection, or negative mode electrospray ionization mass spectrometry (ESI-MS). Calcium (89 mM) was the highest element followed by potassium (38.8 mM) and phosphorous (24 mM). Magnesium and sulfur were also abundant and their concentrations were 15 and 9 mM, respectively. The rest of the elements were found in low amounts (< 2mM). The concentrations of ATP, ADP, and AMP were 16, 31, and 3 m mole/Kg fwt, respectively. GTP, GMP. NAD, FMN, FAD, and riboflavin were found at concentrations below (3 m mole/Kg fwt). The phloem was rich in nomilin 124 mM and limonin 176 m mole/Kg fwt. Hesperidin, vicenin-2, sinensetin, and nobiletin were the most predominant flavonoids. In addition, several hydroxycinnamates were detected. The results of this study will increase our knowledge about the nature and the chemical composition of citrus phloem sap.

“…Also, the flavonoids are beneficial to plants themselves from participating in plants' interactions with other organisms and their reactions to environmental stresses. 2 S. chamaejasme synthesizes a group of flavonoids, which gained much attention due to their biological activities to cancer cells and virus.…”

Stellera chamaejasme L. (Thymelaeaceae), a perennial weed, distributes widely in the grasslands of Russia, Mongolia and China. The plant synthesizes various secondary metabolites including a group of flavonoids. To our knowledge, flavonoids play important roles in the interactions between plants and the environment. So, what are the benefits to S. chamaejasme from producing these flavonoids? Here, we discuss the potential ecological role of flavonoids from S. chamaejasme in protecting the plant from insects and other herbivores, as well as pathogens and competing plant species, and new data are provided on the phytotoxicity of flavonoids from S. chamaejasme toward Poa annua L.Flavonoids are small molecular secondary metabolites synthesized only by plants.
