Transcription profiling of Populus leaves under nitrogen limitation

ABSTRACT: Gene expression response of Populus plants subjected to hydroponic nitrogen manipulation was analyzed using the Affymetrix poplar genome microarrays. Experiment Overall Design: Populus fremontii x angustifolia genotypes were grown hydroponically with either 5 mM (N+) or 0.125 mM (N-) nitrogen. Young and mature leaves at Leaf Plastchron Index (LPI) 2 and 5, respectively, were sampled 4 weeks after the start of low N feeding. Two biological replicates were obtained for each condition.

Transcription profiling of Populus wound induced gene expression changes 1 week; clone RM5

Project description:Gene expression response of Populus plants subjected to leaf wounding was analyzed using the Affymetrix poplar genome microarrays. Experiment Overall Design: Populus fremontii x angustifolia genotypes were grown hydroponically. Wounding treatment was applied by pinching leaves at Leaf Plastchron Index (LPI) 8-12 with pliers at a rate of 10 1-inch wounds per leaf. Young (LPI 0 and LPI 1) and mature leaves (LPI 5) were sampled 1 week after the treatment. Two biological replicates were obtained for each condition.
