    ABSTRACT: Experimental data on the perception of day length and temperature in dormant temperate zone trees are surprisingly scarce. In order to investigate when and where these environmental signals are perceived, we carried out bagging experiments in which buds on branches of Fagus sylvatica, Aesculus hippocastanum and Picea abies trees were exposed to natural light increase or kept at constant 8-h days from December until June. Parallel experiments used twigs cut from the same trees, harvesting treated and control twigs seven times and then exposing them to 8- or 16-h days in a glasshouse. Under 8-h days, budburst in Fagus outdoors was delayed by 41 d and in Aesculus by 4 d; in Picea, day length had no effect. Buds on nearby branches reacted autonomously, and leaf primordia only reacted to light cues in late dormancy after accumulating warm days. Experiments applying different wavelength spectra and high-resolution spectrometry to buds indicate a phytochrome-mediated photoperiod control. By demonstrating local photoperiodic control of buds, revealing the time when these signals are perceived, and showing the interplay between photoperiod and chilling, this study contributes to improved modelling of the impact of climate warming on photosensitive species.

    ABSTRACT: Chloroplasts contain their own genome that is a relic of the endosymbiont that gave rise to the organelle. The coding capacity of the plastome is limited, it only encodes 75–80 proteins (Timmis et al., 2004) of the 3500–4000 proteins present in the chloroplast (Soll & Schleiff, 2004). Nevertheless, its proper expression is essential for plant growth and development (Pogson & Albrecht, 2011). The chloroplast genes of higher plants are transcribed by at least two types of RNA polymerases; the nuclear encoded plastid RNA polymerase (NEP), a T3-T7 bacteriophage type, and the plastid encoded RNA polymerase (PEP), a eubacterial-type multi-subunit enzyme. PEP represents the major transcription machinery in mature chloroplasts and > 80% of all primary plastid transcripts appear to be transcribed by PEP (Zhelyazkova et al., 2012). True to its cyanobacterial origin, PEP has a catalytic core comprised of plastid encoded proteins (rpoA, rpoB, rpoC1 and rpoC2). Additionally, the nuclear encoded sigma factors are required for promoter specificity (Hanaoka et al., 2003) and refined proteomic studies have revealed several additional nuclear-encoded proteins constituting this multimeric enzyme. Genetic disruption of these subunits severely compromises PEP-mediated transcription, suggesting that PEP has an intricate organization (Pfalz & Pfannschmidt, 2013). Despite their essential role, we know very little about the specific roles of these PEP-associated proteins in plastid transcription. In this issue of New Phytologist, Pfalz et al. (2015; pp. 1024–1037) use detailed biochemical analysis to characterize one of the associated PEP proteins in maize, ZmpTAC12. ZmpTAC12 is shown to interact with single-stranded nucleic acids and to be required for the assembly of the PEP-complex. The work by Pfalz et al. (2015) presents a new model where the PEP-associated proteins are essential for the structural establishment of chloroplast transcriptional activity.
