Widespread co-occurrence of multiple ploidy levels in fragile ferns (Cystopteris fragilis complex; Cystopteridaceae) probably stems from similar ecology of cytotypes, their efficient dispersal and inter-ploidy hybridization.

Ann Bot 2018 Dec 12. Epub 2018 Dec 12.

Department of Botany, Faculty of Science, University of South Bohemia, Branišovská, Ceské Budejovice, Czech Republic.

Background And Aims: Polyploidy has played an important role in the evolution of ferns. However, the dearth of data on cytotype diversity, cytotype distribution patterns and ecology in ferns is striking in comparison with angiosperms and prevents an assessment of whether cytotype coexistence and its mechanisms show similar patterns in both plant groups. Here, an attempt to fill this gap was made using the ploidy-variable and widely distributed Cystopteris fragilis complex. Read More

Functionally distinct assembly of vascular plants colonizing alpine cushions suggests their vulnerability to climate change.

Ann Bot 2018 Dec 12. Epub 2018 Dec 12.

Institute of Botany, The Czech Academy of Sciences, Průhonice, Czech Republic.

Background And Aims: Alpine cushion plants can initially facilitate other species during ecological succession, but later on can be negatively affected by their development, especially when beneficiaries possess traits allowing them to overrun their host. This can be reinforced by accelerated warming favouring competitively strong species over cold-adapted cushion specialists. However, little empirical research has addressed the trait-based mechanisms of these interactions. Read More

Transgenerational effects of ungulates and pre-dispersal seed predators on offspring success and resistance to herbivory.

PLoS One 2018 12;13(12):e0207553. Epub 2018 Dec 12.

Departamento de Zoología, Universidad de Granada, Granada, Spain.

Herbivorous mammals and insect pre-dispersal seed predators are two types of herbivores that, despite their functional and morphological differences, tend to severely impact many plant species, highly decreasing their seed production and even imperiling the performance of their offspring through transgenerational effects. However, how they influence offspring resistance to herbivory remains largely unknown. In this study we experimentally examined the effects of ungulates and pre-dispersal seed predators on seed quality as well as on the emergence, survival and resistance to herbivory of the seedlings of a semiarid herb.

Genome-wide functional analyses of plant coiled-coil NLR-type pathogen receptors reveal essential roles of their N-terminal domain in oligomerization, networking, and immunity.

PLoS Biol 2018 Dec 12;16(12):e2005821. Epub 2018 Dec 12.

Molecular Plant Pathology, Swammerdam Institute for Life Sciences, University of Amsterdam, Amsterdam, the Netherlands.

The ability to induce a defense response after pathogen attack is a critical feature of the immune system of any organism. Nucleotide-binding leucine-rich repeat receptors (NLRs) are key players in this process and perceive the occurrence of nonself-activities or foreign molecules. In plants, coevolution with a variety of pests and pathogens has resulted in repertoires of several hundred diverse NLRs in single individuals and many more in populations as a whole. Read More

Early-life environment and differences in costs of reproduction in a preindustrial human population.

PLoS One 2018 12;13(12):e0207236. Epub 2018 Dec 12.

Department of Biology, University of Turku, Turku, Finland.

Reproduction is predicted to trade-off with long-term maternal survival, but the survival costs often vary between individuals, cohorts and populations, limiting our understanding of this trade-off, which is central to life-history theory. One potential factor generating variation in reproductive costs is variation in developmental conditions, but the role of early-life environment in modifying the reproduction-survival trade-off has rarely been investigated. We quantified the effect of early-life environment on the trade-off between female reproduction and survival in pre-industrial humans by analysing individual-based life-history data for >80 birth cohorts collected from Finnish church records, and between-year variation in local crop yields, annual spring temperature, and infant mortality as proxies of early-life environment.

Social and ecological conditions of cranberry production and climate change attitudes in New England.

PLoS One 2018 12;13(12):e0207237. Epub 2018 Dec 12.

Earth and Environmental Sciences, Boston College, Chestnut Hill, Massachusetts, United States of America.

Cranberry growers in New England are increasingly pressured by negative effects associated with global climate change, some of which are familiar to this group (such as precipitation fluctuations and pest pressures), others that are rather new (such as warmer winters that threaten needed chill hours for the plants to bloom). The first study of this population of its kind, we use a survey, supplemented with observations and interviews, to assess Massachusetts cranberry grower attitudes towards climate change, and whether certain conditions of production might be associated with their attitudes. Our findings suggest that certain personal and ecological conditions are associated with greater worry of climate change effects, and that communal conditions of the cranberry grower social network provide some ways to cope with a warming climate.

Department of Biochemistry, Molecular Biology, Entomology and Plant Pathology, Mississippi State University, Mississippi State, Mississippi, United States of America.

Plant protein kinases form redundant signaling pathways to perceive microbial pathogens and activate immunity. Bacterial pathogens repress cellular immune responses by secreting effectors, some of which bind and inhibit multiple host kinases. To understand how broadly bacterial effectors may bind protein kinases and the function of these kinase interactors, we first tested kinase-effector (K-E) interactions using the Pseudomonas syringae pv.

Phytopathology 2018 Dec 12. Epub 2018 Dec 12.

University of Lethbridge, Department of Biological Sciences, Lethbridge, Alberta, Canada ;

Plant signalling hormones, such as ethylene, have been shown to affect the host response to various pathogens. Often the resistance responses to necrotrophic fungi are mediated through synergistic interactions of ethylene (ET) with the jasmonate signalling pathway. On the other hand, ethylene is also an inducer of senescence and cell death, which could be beneficial for some invading necrotrophic pathogens. Read More

Cesium has no known beneficial effects on plants and while plants have the ability to absorb it through the root system, plant growth is retarded at high concentrations. Recently, we have shown that potassium influx through a potassium channel complex AKT1-KC1 is inhibited by cesium in Arabidopsis thaliana and the resultant reduction in potassium accumulation in the plant is the primary cause of retarded growth. By contrast, a major potassium transporter, HAK5 whose function is crucial under potassium deficiency, was found to be either not affected or complementary under cesium stress in the low affinity potassium range.

Combing both simulated and field-measured data to develop robust hyperspectral indices for tracing canopy transpiration in drought-tolerant plant.

Environ Monit Assess 2018 Dec 11;191(1):13. Epub 2018 Dec 11.

Xinjiang Institute of Ecology and Geography, CAS, Urumqi, 830011, China.

Transpiration plays a key role in water and energy fluxes at various scales. While in recent remote sensing offers a fast and convenient method for tracing transpiration at multiple scales, the approach is mostly indirect and relies on energy balance. Although several hyperspectral indices have been reported to show potentials for tracing transpiration directly, both at leaf and canopy scales, they remain in pioneer stages and need extensive validations.

Inevitable Decay: Debates over Climate, Food Security, and Plant Heredity in Nineteenth-Century Britain.

J Hist Biol 2018 Dec 11. Epub 2018 Dec 11.

History Faculty, University of Oxford, George St., Oxford, OX1 2RL, UK.

Climate change and the failure of crops are significant but overlooked events in the history of heredity. Bad weather and dangerously low harvests provided momentum and urgency for answers to questions about how best to improve and acclimatize staple varieties. In the 1790s, a series of crop failures in Britain led to the popularization of and widespread debate over Thomas Andrew Knight's suggestion that poor weather was in fact largely unconnected to the bad harvests.
