Proteome readjustments in the apoplastic space of Arabidopsis thaliana ggt1 mutant leaves exposed to UV-B radiation [PDF]
, 2015 Ultraviolet-B radiation acts as an environmental stimulus, but in high doses it has detrimental effects on plant metabolism. Plasma membranes represent a major target for ROS generated by this harmful radiation.

Identification and Analysis of Proteins Sharing Dehydroascorbate Reductase Activity
Biologia plantarum, 2002 Dehydroascorbate (DHA)-reducing proteins were observed using a native-PAGE/activity staining method, and identified in soybean and rice by Western analysis using antibodies against homologous protein known to catalyse DHA reduction. Administration of 1 mM DHA apparently did not trigger DHA reductase activity in lupin and onion, whereas activity was ...

Proteomic changes and molecular effects associated with Cr(III) and Cr(VI) treatments on germinating kiwifruit pollen [PDF]
, 2011 The present study is aimed at identifying molecular changes elicited by Cr(III) and Cr(VI) on germinating kiwifruit pollen. To address this question, comparative proteomic and DNA laddering analyses were performed. While no genotoxic effect was detected,

Ex vitro acclimatization of plantain plantlets micropropagated in temporary immersion bioreactor
Biologia Plantarum, 2010 Plantain (Musa ABB CEMSA 3/4) plantlets were micropropagated in temporary immersion bioreactors (TIB) or in gelled medium (GM). After ex vitro transfer ROS accumulation was determined by infiltrating leaves with nitroblue tetrazolium (NBT) and 3,3 ...

The evolution of glutathione metabolism in phototrophic microorganisms [PDF]
The low molecular weight thiol composition of a variety of phototropic microorganisms is examined in order to ascertain how evolution of glutathione (GSH) production is related to the evolution of oxygenic photosynthesis.
