  • Deciduous trees exhibit autumn senescence driven by environmental seasonality. Here, the authors show that senescence timing in aspen tree genotypes depends on environmental changes but also on the ability of each genotype to sustain stress tolerance mediated by the phytohormone salicylic acid.

  • Molecular mechanism of how temperature-mediated control of bud break in perennial plants remains unclear. Here, the author show that transcriptional factor SHORT VEGETATIVE PHASE-LIKE and its downstream target TCP18 are negative regulators of hybrid aspen bud break.

  • The draft genome of the Norway spruce (P. abies) is presented; this is the first gymnosperm genome to be sequenced and reveals a large genome size (20 Gb) resulting from the accumulation of transposable elements, and comparative sequencing of five other gymnosperm genomes provides insights into conifer genome evolution.

  • Eileen Furlong and colleagues report the development and application of BiTS-ChIP (batch isolate tissue specific chromatin immunoprecipitation), in which a tagged nuclear protein is expressed in developing cells of interest. They apply this method to investigate six chromatin markers and RNA Pol II occupancy in mesodermal cells in developing Drosophila embryos and find that histone modifications and Pol II occupancy can predict enhancer activity.

  • The molecular nature of large-cell neuroendocrine lung carcinomas (LCNEC) has remained unclear. Here, the authors show LCNECs represent a distinct transcriptional subgroup among lung cancers and comprise two molecular subgroups, type I (TP53 and STK11/KEAP1 alterations) and type II (TP53 and RB1 inactivation).

  • Plants are sensitive to temperature changes. Now, researchers have found an alternative splicing factor that is essential for the development of Arabidopsis under low temperature, and bridges between alternative splicing and temperature sensitivity.

  • In an inter-laboratory study, the authors compare the accuracy and performance of three optical density calibration protocols (colloidal silica, serial dilution of silica microspheres, and colony-forming unit (CFU) assay). They demonstrate that serial dilution of silica microspheres is the best of these tested protocols, allowing precise and robust calibration that is easily assessed for quality control and can also evaluate the effective linear range of an instrument.
