      abstract     = {Growing leaves do not expand at a constant rate but exhibit
                      pronounced diel growth rhythms. However, the mechanisms
                      giving rise to distinct diel growth dynamics in different
                      species are still largely unknown. As a first step towards
                      identifying genes controlling rate and timing of leaf
                      growth, we analysed the transcriptomes of rapidly expanding
                      and fully expanded leaves of Populus deltoides Bartr. ex.
                      Marsh at points of high and low expansion at night. Tissues
                      with well defined temporal growth rates were harvested using
                      an online growth-monitoring system based on a digital image
                      sequence processing method developed for quantitative
                      mapping of dicot leaf growth. Unlike plants studied
                      previously, leaf growth in P. deltoides was characterised by
                      lack of a base-tip gradient across the lamina, and by
                      maximal and minimal growth at dusk and dawn, respectively.
                      Microarray analysis revealed that the nocturnal decline in
                      growth coincided with a concerted down-regulation of
                      ribosomal protein genes, indicating deceleration of
                      cytoplasmic growth. In a subsequent time-course experiment,
                      Northern blotting and real-time RT-PCR confirmed that the
                      ribosomal protein gene RPL12 and a cell-cycle gene H2B were
                      down-regulated after midnight following a decrease in
                      cellular carbohydrate concentrations. Thus, we propose that
                      the spatio-temporal growth pattern in leaves of P. deltoides
                      primarily arises from cytoplasmic growth whose activity
                      increases from afternoon to midnight and thereafter
                      decreases in this species.},
