Journal description

New Phytologist is an online-only journal owned by the New Phytologist Trust, a not-for-profit organization dedicated to the promotion of plant science. New Phytologist publishes original research on all aspects of plant science in a lively format including expert comment, correspondence and timely reviews. The Trust ensures that any excess revenue from the journal is put straight back into the subject and facilitates projects from Symposia to free access for our Tansley reviews.

    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.

    ABSTRACT: Although numerous studies have shown the ability of silicon (Si) to mitigate a wide variety of abiotic and biotic stresses, relatively little is known about the underlying mechanism(s). Here, we have investigated the role of hormone defense pathways in Si-induced resistance to the rice brown spot fungus Cochliobolus miyabeanus. To delineate the involvement of multiple hormone pathways, a multidisciplinary approach was pursued, combining exogenous hormone applications, pharmacological inhibitor experiments, time-resolved hormone measurements, and bioassays with hormone-deficient and/or -insensitive mutant lines. Contrary to other types of induced resistance, we found Si-induced brown spot resistance to function independently of the classic immune hormones salicylic acid and jasmonic acid. Our data also rule out a major role of the abscisic acid (ABA) and cytokinin pathways, but suggest that Si mounts resistance to C. miyabeanus by preventing the fungus from hijacking the rice ethylene (ET) machinery. Interestingly, rather than suppressing rice ET signaling per se, Si probably interferes with the production and/or action of fungal ET. Together our findings favor a scenario whereby Si induces brown spot resistance by disarming fungal ET and argue that impairment of pathogen virulence factors is a core resistance mechanism underpinning Si-induced plant immunity.
