Stress enhances the gene expression and enzyme activity of phenylalanine ammonia-lyase and the endogenous content of salicylic acid to induce flowering in pharbitis

Arbuscular mycorrhizal fungi enhances salinity tolerance ofPanicum turgidumForssk by altering photosynthetic and antioxidant pathways

“…Similar to our results in Anethum graveolens L., Mehr et al (2012) also demonstrated enhanced accumulation of phenols with increasing salt concentration. Greater accumulation of phenolics in plants subjected to stressful conditions is ascribed to the upregulation of the enzymes involved in their synthesis (Wada et al 2014). In our study, increased phenols content in stressed plants corroborate with the findings of Mehr et al (2012) for A. graveolens L., Tomar and Agarwal (2013) for wheat and Dawood et al (2014) for Vicia faba.…”

Gibberellin-induced changes in the transcriptome of grapevine (Vitis labrusca × V. vinifera) cv. Kyoho flowers

“…The phenylpropanoid pathway has been shown to be coordinated in ripening fruit with the activity of the enzymes involved in the synthesis of flavonoids [71], and many of the distinctive features of fleshy fruits, such as the appearance of characteristic color at ripening, are related to changes in the synthesis and accumulation of phenolic compounds [71]. Moreover, salicylic acid (SA), which can induce flowering, is known to be a downstream product of this pathway [72-74]. These results suggest that both the early opening of flowers and induction of fruit coloring in GA 3 -treated samples (Figure 2A-I) might be triggered, at least in part, by the increased expression of PAL genes and synthesis of SA.…”

Potential of efficient and resistant plant growth‐promoting rhizobacteria in lead uptake and plant defence stimulation in Lathyrus sativus under lead stress

“…It has been reported that, under heavy metal stress, antioxidative properties of phenolic compounds might relate to their ability to chelate transition metal ions, inhibiting the superoxide‐driven Fenton reaction, resulting in efficient scavenging of toxic radicals and better growth performance (Wada et al . ).…”

“…In fact, phenolics mitigate oxidative stress and increase membrane stability by decreasing membrane fluidity and contribute to increased cell wall rigidity and creation of physical barriers that prevent the harmful action of heavy metals on cells (D ıaz et al 2001;Kattab 2007). It has been reported that, under heavy metal stress, antioxidative properties of phenolic compounds might relate to their ability to chelate transition metal ions, inhibiting the superoxide-driven Fenton reaction, resulting in efficient scavenging of toxic radicals and better growth performance (Wada et al 2014).…”
