In species with high gene flow and consequent low interpopulation differentiation over wide geographic ranges, differential gene expression along ecological gradients often reveals adaptive significance. We investigated potential differences in protein expression between Picea abies ecotypes adapted to contrasting altitude conditions. Protein expression patterns were compared between needles an...

Stilbenes are dibenzyl polyphenolic compounds produced in several unrelated plant families that appear to protect against various biotic and abiotic stresses. Stilbene biosynthesis has been well described in economically important plants, such as grape (Vitis vinifera), peanut (Arachis hypogaea), and pine (Pinus species). However, very little is known about the biosynthesis and ecological role ...

The mechanism of water-stress-induced xyletn embolism was studied in three species of conifers: Abies balsamca (L.) Mill., Picea rtibens Sarg. and ./uniperus virginiana L. Each species showed a characteristic relationship between xylem tension and the loss of hydraulic conductivity by air etnbolistn. Abies balsamea and Picea rubens began to etnbolize at tensions between 2 and 3 MPa and were com...
