“…6) An increase in lignin content has already been reported in Cu 2þ -treated plants species, e.g. in Capsicum annuum [14] Raphanus sativus [8], Glycine max [32] and Panax ginseng [2]. The polymerization of lignin precursors is currently known to be catalysed by peroxidases and by laccases, which are Cu-containing glycoproteins [5,14,32,58].…”

“…The increasing of Cu level in root tissues was followed by the rising of lignification. Lignin, comprising of phenolic hetero polymers, was a complex component of cell wall (Lin et al, 2005). The adding of nano-CuO on Glycine max at 100, 200, 400, and 500 mg/L enhanced the lignification of root cells, thereby affecting the root development Remarks: The means in one column followed by the same letter were not significantly different according to DMRT (α 5%).…”

The experiment aimed to identify the root response of eight oil palm hybrids to copper toxicity. The factorial treatments were arranged in Randomized Completely Block Design with three blocks as replication. The first factor was the copper toxicity, while eight oil palm hybrids (DxP) consisted of Yangabi (P1), Avros (P2), Langkat (P3), PPKS 239 (P4), Simalungun (P5), PPKS 718 (P6), PPKS 540 (P7), and Dumpy (P8) as second factor. Root growth variables were observed, including total root length, total root area, root volume and diameter, copper content on root, fractal dimension, relative root water content, fresh root weight, and root dry weight. Data were analysed using analysis of variance (ANOVA) and continued with Duncan's Multiple Range Test at α=5%. There was a declinning in total root length, volume and diameter, fresh and dry weight as the copper content rose on the root tissue, but no significant different was found in total root area.

“…On the other hand, several works have reported the involvement of Cu and Mn in the shikimic acid pathway leading to the biosynthesis of several phenols, such as flavonoids, tannins, and lignin (Santiago et al, 2000;Diaz et al, 2001;Loponen et al, 2001;Lin et al, 2005;Guangqiu et al, 2007). Moreover, it is known that Cu and Mn influence the activity of many cellular enzymes, such as phenylalanine ammonia-lyase (PAL) (Santiago et al, 2000;Kováčik & Klejdus, 2008;Treutter, 2010), peroxidases (Diaz et al, 2001, Lin et al, 2005, Gross, 2008Kováčik et al, 2009), laccases (Lin et al, 2005), and shikimate dehydrogenase (Diaz et al, 2001, Kováčik et al, 2009.…”

Eugenia unifl ora L., Myrtaceae, leaves contain high amounts of phenolic compounds which are responsible for several pharmacological activities. In order to evaluate the phenolics seasonal variation leaves were analysed on a monthly basis during the period of two years for the contents of hydrolysable tannins, total phenols, fl avonoids, and nutrients (N, P, K, S, Ca, Mg, Mn, Zn, Cu, and Fe). Results were correlated with climate conditions (rainfall, humidity, and mean temperature) by Principal Component and Cluster Analysis which allowed four groups to be distinguished with respect to the age of the leaves and the content of some metals. Young leaves were characterised by high levels of Zn and nitrogen whereas old leaves contained high levels of Fe and calcium, and both groups had moderate amounts of phenolics. Adult leaves were divided in two groups and results revealed that while one group had the highest levels of all phenols and lowest amounts of Mn and Cu, the other showed opposite quantities. The Canonical Correlation Analysis confi rmed a highly signifi cant negative correlation between phenol contents and Mn and Cu. These facts suggested that fl avonoids and tannins production depends of the amounts of foliar nutrients, Cu and Mn in particular, which are cofactors of enzymes involved in phenol degradation and lignin biosynthesis. This knowledge can improve this specie cultivation in order to enhance the phenolic compounds concentration.
