Transcription profiling by array of poplar grown in different light and temperature cycles

ABSTRACT: Poplar (Populus trichocarpa, clone Nisqually-1) plants were grown in a Conviron PGR 15 growth chamber using precise control of temperature, light, and humidity. Diurnal (driven) conditions included 12L:12D light cycles and 25C/12C thermocycles in three different combinations. These were: photocycles (LDHH), 12 hrs. light (L)/12 hrs. dark (D) at a constant temperature (25C; HH); photo/thermocycles (LDHC): 12 hrs. light (L) /12 hrs. dark (D) with a high day temperature (25C) and a low night temperature (12C); and thermocycles (LLHC): continuous light (LL) with 12 hrs. high/12 hrs. low temperature (25C, day; 12C, night). Light intensity and relative humidity were 700 micromol m-2s-2 and 50%, respectively. Three-month-old poplar plants were entrained for at least one week under the respective condition prior to initiation of each experiment. Leaves and stems from individual poplar plants were collected every four hours for 48 hrs in driven (diurnal) conditions followed by a two day freerun spacer under continuous light/temperature followed by two additional days of sampling under the same continuous free run condition.

Circadian clocks provide an adaptive advantage through anticipation of daily and seasonal environmental changes. In plants, the central clock oscillator is regulated by several interlocking feedback loops. It was shown that a substantial proportion of the Arabidopsis genome cycles with phases of peak expression covering the entire day. Synchronized transcriptome cycling is driven through an extensive network of diurnal and clock-regulated transcription factors and their target cis-regulatory ele  ...[more]
