Soil cadmium toxicity and nitrogen deposition differently affect growth and physiology in Toxicodendron vernicifluum seedlings

Complete Chloroplast Genome Sequence of Chinese Lacquer Tree (Toxicodendron vernicifluum, Anacardiaceae) and Its Phylogenetic Significance

“…Many recent studies of the Chinese lacquer tree have focused on secondary metabolites [9][10][11], anatomic features [12][13][14], growth traits [15][16][17], and classification and evaluation of cultivars of the species [18,19]. Since 1978, more than 90 local cultivars, including some rare ones, have been recognized [20].…”

Di-n-butyl phthalate-induced phytotoxicity in Hordeum vulgare seedlings and subsequent antioxidant defense response

“…Activity of CAT followed an increasing trend in the shoots and roots of barley seedlings under DBP exposure. In the various studies, the increase in CAT activity is reported to be correlated positively with H2O2 generation during stress (Choudhary et al 2012, Li et al 2013. Moreover, phthalates are also reported to enhance the production of H2O2 remarkably in plants (Bai et al 2009, Zhang et al 2014.…”

Surface chromium on Terracotta Army bronze weapons is neither an ancient anti-rust treatment nor the reason for their good preservation

“…Microscopic examination and Raman analyses of lacquer samples failed to identify any crystalline form of chromium, thus making it unlikely that a ground mineral such as chromite, crocoite (PbCrO 4 ), or other water-insoluble oxide would have been mixed in. Although some plants are known to be tolerant to toxic elements such as chromium 38 the lacquer tree is not among them 39 . Even if the ashes of a chromium hyperaccummulator plant were to have been mixed with the lacquer, a substantial quantity of these would have been needed to raise the bulk chromium in the lacquer to detectable levels.…”
