Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In this work, Calotropis procera latex extract (CPLE) was evaluated as an environmentally benign corrosion inhibition on mild steel in 1‐M HCl using gravimetric, electrochemical, surface, and computational approaches. The results revealed that CPLE exhibited an efficient corrosion inhibitor with the efficiency of 94.26% and 93.10% at 200‐ppm ...

An Expanding Role For Purine Uptake Permease (PUP) -like Transporters In Plant Secondary Metabolism.
Frontiers in Plant Science, 2012 For the past decade, our understanding of the plant purine uptake permease (PUP) transporter family of was primarily oriented on purine nucleobase substrates and their tissue-specific expression patterns in Arabidopsis.

Soil-borne microorganisms and soil-type affect pyrrolizidine alkaloids in Jacobaea vulgaris [PDF]
Secondary metabolites like pyrrolizidine alkaloids (PAs) play a crucial part in plant defense. We studied the effects of soil-borne microorganisms and soil-type on pyrrolizidine alkaloids in roots and shoots of Jacobaea vulgaris.
