Seasonal differences in expression patterns of LMPC-enriched poplar wood rays

ABSTRACT: Ray cells were enriched from wood samples of poplar (Populus x canescens) by LMPC and transcripts monitored by poplar whole genome microarrays. Results provided insight into molecular processes during the transition from dormancy to flowering in early spring in contrast to the active growth phase in summer. 4 samples of summer (July) 4 of early spring (February) from Populus x canescens field-culture

ORGANISM(S): Populus tremula x Populus alba

Understanding seasonality and longevity is a major challenge in tree biology. In woody species, growth phases and dormancy follow one another consecutively. In the oldest living individuals, the annual cycle may run for more than 1,000 years. So far, however, not much is known about the processes triggering reactivation from dormancy. In this study, we focused on wood rays, which are known to play an important role in tree development. The transition phase from dormancy to flowering in early spr  ...[more]
