Post-harvest UV-B irradiation induces changes of phenol contents and corresponding biosynthetic gene expression in peaches and nectarines.

Claudia Scattino et al.

Food chemistry, 163, 51-60 (2014-06-11)

In the present study the possibility of enhancing phenolic compound contents in peaches and nectarines by post-harvest irradiation with UV-B was assessed. Fruits of 'Suncrest' and 'Babygold 7' peach and 'Big Top' nectarine cultivars were irradiated with UV-B for 12

Isoprene emission by poplar is not important for the feeding behaviour of poplar leaf beetles.

Anna Müller et al.

BMC plant biology, 15, 165-165 (2015-07-01)

Chrysomela populi (poplar leaf beetle) is a common herbivore in poplar plantations whose infestation causes major economic losses. Because plant volatiles act as infochemicals, we tested whether isoprene, the main volatile organic compound (VOC) produced by poplars (Populus x canescens)

Aedesin: structure and antimicrobial activity against multidrug resistant bacterial strains.

Sylvain Godreuil et al.

PloS one, 9(8), e105441-e105441 (2014-08-28)

Multidrug resistance, which is acquired by both Gram-positive and Gram-negative bacteria, causes infections that are associated with significant morbidity and mortality in many clinical settings around the world. Because of the rapidly increasing incidence of pathogens that have become resistant
